Adds metareview source-review to review the committed first-party source of a whole repository. It uses the logged-in Claude, Grok, or Codex CLI and saves findings.json plus a standalone HTML report outside the repository.

Quick start

From a metareview source checkout:

bin/source-review --model grok --repo /path/to/repo

Both --model and --repo are required. The script builds metareview automatically and prints a unique report directory under /tmp. Replace grok with opus or astra; use --repo . to review your current directory. You need Go and a logged-in provider CLI. The README includes this example and the full CLI options.

Changes

  • One command supports --model opus|grok|astra, with shared source preparation, findings schema, and result handling.
  • Adds bin/source-review as a simple source-checkout entry point, with automatic builds and report directories, plus a README walkthrough.
  • Selects a fixed HEAD snapshot; skips tests, docs, dependencies, and generated files. Repeated --path options support smaller reviews of real repository code.
  • Packs source into bounded prompts with original line numbers, splitting oversized files and avoiding repeated prompt reconstruction.
  • Gives Opus and Grok the same system prompt, disabled tools, and medium effort. Grok receives each complete prompt directly, eliminating its tool-driven prompt rereading. Calls run in temporary workspaces with provider-specific settings to limit local instruction injection.
  • Adds parallel calls (--jobs, default 8), per-call timeouts (--call-timeout, default 30m), progress reporting, and process cleanup on failure or interruption.
  • Handles provider response formats, rejects explicit incomplete responses, and validates findings against committed filenames and line ranges. Invalid individual findings are skipped with diagnostics.
  • Saves reports only after all calls succeed; publication errors restore previous reports, retaining backups if restoration fails.
  • Adds an offline HTML review page with severity summaries, an area map, filters, filename/text search, findings grouped by file, expandable source excerpts, and dark/mobile layouts.
  • Adds regression tests, HTML interaction checks, a bin/ci coverage entry point, and command documentation in docs/ARCHITECTURE.md.

Verification

  • make cover passed, including the required coverage gate and Go/shell checks.
  • Source-review package coverage is 100%; its race checks passed.
  • git diff --check passed.
  • The wrapper passed controlled end-to-end checks for all three providers, required flags in either order, relative paths with spaces, explicit current repo, unique report directories, and provider failures; bash -n and shellcheck also passed.
  • Task-done and PR-ready reviews passed with advisories and zero blocking findings.

Limits

Codex currently cannot disable its tools or replace its system prompt, so Astra shares the user prompt and schema but differs in those settings. Matching Opus's review accuracy while keeping Grok within 3x its runtime remains unproven; this PR does not claim that target has been achieved.

…, Astra, or Grok

Separate from diff review. Keeps Classify-Code UTF-8 product files and drops tests, vendor, generated code, config, and docs. A short citation maps to the one kept path that ends with it. A finding that still does not match is skipped. Writes findings.json and a self-contained HTML page.
The findings list is a ruled sheet with a severity edge on each row. Opening a row places the issue and consequence beside the quoted lines.

Summary by CodeRabbit

  • New Features
    • Added whole-repository source reviews with Opus, Astra, or Grok, configurable concurrency and timeouts, and optional path filters.
    • Reviews first-party source while excluding tests, generated files, vendored or third-party code, documentation, configuration, and non-UTF-8 files.
    • Saves findings and a self-contained HTML report to a specified directory outside the repository. The report includes severity and directory filters, search, expandable findings, and cited source excerpts.
  • Documentation
    • Documented the command, its options, and review scope.

Walkthrough

This change adds a whole-repository source review command. It selects eligible files from Git HEAD, sends bounded prompts to a selected model CLI, parses findings, and writes JSON and HTML output. It also adds a shell wrapper for the coverage target.

Changes

Whole-repository source review

Layer / File(s) Summary
Git snapshot and source selection
internal/sourcereview/git.go, internal/sourcereview/select.go, internal/sourcereview/fixture_test.go, internal/sourcereview/select_test.go
Reads committed file blobs and classifies paths as kept first-party source or dropped files. Tests cover selection rules, Git output parsing, and error cases.
Model calls and prompt packing
internal/sourcereview/model.go, internal/sourcereview/pack.go, internal/sourcereview/model_test.go, internal/sourcereview/pack_test.go
Maps Astra, Opus, and Grok to their CLI commands and parses their response formats. Packs files into prompts within a byte budget and slices oversized files at UTF-8 boundaries.
Finding parsing and review page
internal/sourcereview/parse.go, internal/sourcereview/page.go, internal/sourcereview/parse_test.go, internal/sourcereview/page_test.go
Validates findings and resolves cited paths against selected files. Renders a self-contained HTML page with severity and directory filters and source excerpts.
Command orchestration and output
internal/sourcereview/run.go, internal/sourcereview/run_test.go, cmd/metareview/main.go, cmd/metareview/main_test.go, docs/ARCHITECTURE.md
Connects the CLI to source selection, model calls, finding parsing, and output writes. Refuses output directories inside the reviewed repository. Tests cover CLI flags, concurrency, timeouts, and failure handling.
Feature records and local tooling
metareview-whole-repo-source-review-*.md, metareview-grok-source-review-*.md, metareview-grok-speed-*.md, .gitignore, bin/ci
Adds goal and progress records for source review and Grok execution, ignore rules for local Claude files, and a script that runs make cover.

Merge Risk: 🟠 High · up to 6eba3

The review command still has correctness, reliability, and scalability issues that can produce incomplete or failed reviews, so it is not ready to merge.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 6eba3

The new review command can print complete source to terminal logs, and interruption or failed output writes can leave review work running or results out of date. It is opt-in, but these behaviors matter when reviewing sensitive repositories.

Retained concerns

  • Medium · security · observed: The new command prints each full source-bearing prompt to stdout before invoking the selected model. When stdout is captured or shared, that creates a copy of reviewed source outside the selected output directory, including on failed runs.
  • Medium · security · inferred: Operator interruption is not connected to the review context. Because model children run in separate process groups, interruption may leave them processing source until their individual timeout; abrupt parent termination can also bypass deferred prompt-file cleanup. Actual signal delivery depends on the launcher.
  • Low · reliability · inferred: Review results are not published as one generation. Reusing an output directory can leave old artifacts after a failed review, while failure during the second direct write can leave an old or partial page without its matching findings file. A consumer that ignores the command's failure status could mistake these for current security results.
Security review details

Security Blast Radius

  • inferred — For an operator-selected repository, the independently exposed copies are model-process inputs, complete prompts on stdout, and finding artifacts in the output directory. The maximum shared-log or filesystem audience cannot be determined from this PR.

Security Findings and Attack Paths

  • observed — Writing the prompt to stdout precedes each model call and is not conditional on successful parsing or output publication. Disclosure to another party requires stdout to be captured or accessible to that party.
  • inferred — A caller treating interruption or a reused output directory as a completed rollback can encounter continuing model work or old and mismatched artifacts. Internal timeouts and failure exit codes reduce, but do not eliminate, those contingent outcomes.

Trust Boundaries and Controls

  • observed — Committed file content is supplied as review data to a selected model CLI. Tool restrictions, finding validation against kept files, output-directory containment, and HTML escaping constrain separate execution and rendering paths; they do not control stdout retention.

Resilience and Maintainability Implications

  • observed — Model-call errors cancel sibling work and ordinary function return removes temporary model files. The context originates inside the review rather than at the public command, and direct output writes have no generation-level rollback.

Hardening Proposals

  • proposed — Make full-prompt stdout logging an explicit opt-in and keep routine progress output free of source bodies.
  • proposed — Propagate an operator-cancellable context to child processes and publish findings and HTML as a clearly identified, paired result generation.

In `@internal/sourcereview/git.go`:
- Around line 72-88: Update readBlobs to support paths containing newlines:
remove the newline rejection and send each HEAD:path request using NUL-delimited
input with cat-file’s NUL mode. Ensure the batch response is still parsed
correctly for the supplied paths.

In `@internal/sourcereview/model.go`:
- Around line 80-85: Update the Grok branch in `model.go` to write the prompt to
a private temporary file, pass its path with `--prompt-file` instead of
including the prompt in argv, and remove the file after `runner.Run` returns.
Preserve the existing error and output handling; update the goal contract and
`TestCallShapes` to verify the argument shape and temporary-file lifecycle.

In `@internal/sourcereview/pack.go`:
- Around line 88-101: Update `packWhole` to track each bin’s prompt size
incrementally instead of copying candidate slices and rebuilding prompts with
`promptWith` for every placement check. Account for the base prompt and the
separator and file-content bytes described in the comment, then build each
output prompt once from the completed bins.

In `@internal/sourcereview/page_test.go`:
- Around line 117-121: Update runPage to check for Node.js with exec.LookPath
before invoking exec.Command; skip the test when Node.js is unavailable locally,
but fail when CI is set so the DOM proof remains mandatory in CI.

In `@internal/sourcereview/parse.go`:
- Around line 127-148: Update extractFindings to accept only the complete body
returned by objectText: propagate its error, reject the body when findingsObject
fails, and remove the scan that accepts findings embedded in surrounding prose
or trailing text. Ensure malformed or unclosed fences fail rather than yielding
an empty review.
- Around line 44-63: Update Parse so failures from decodeEntry, f.Validate, and
resolveKept, as well as nonexistent EndLine values, return an error immediately
instead of being appended to skipped and continuing; preserve successful-entry
handling.

In `@internal/sourcereview/select.go`:
- Around line 35-43: Resolve HEAD once in the selection flow and use the
resulting commit SHA for both `ls-tree` and blob reads. Update `readBlobs` to
accept the revision and format each blob specifier as that revision plus the
path, then pass `commit` from the caller.
- Around line 48-59: Split keepPath into path-only and body-dependent checks,
using the existing path-based exclusions before loading file contents. Call
readBlobs only for paths that pass the path check, then apply the body check to
those blobs and preserve the existing kept and dropped results.

In `@metareview-whole-repo-source-review-progress.md`:
- Around line 1-7: Remove the transient session progress document from the PR,
and preserve the feature contract from the goal document in durable
documentation. Retain the contract while omitting session-specific identifiers,
temporary evidence paths, and workflow status or directives.

Note that: - the behaviour is slightly different from that of &quot;/bin/ls&quot; in that the denotes just a list of patterns to match, e.g. so specifying directory name (without `-r`) will behave differently, and order of the arguments does not matter. - the behaviour is similar to that of &quot;/bin/ls&quot; in that the is taken as relative to the current working directory. E.g. when you are in a directory sub that has a directory dir, you can run git ls-tree -r HEAD dir to list the contents of the tree (that is `sub/dir` in `HEAD`). You don’t want to give a tree that is not at the root level (e.g. `git` `ls-tree` `-r` `HEAD:sub` `dir`) in this case, as that would result in asking for `sub/sub/dir` in the `HEAD` commit. However, the current working directory can be ignored by passing --full-tree option. ## OPTIONS : Id of a tree-ish. -d : Show only the named tree entry itself, not its children. -r : Recurse into sub-trees. -t : Show tree entries even when going to recurse them. Has no effect if `-r` was not passed. `-d` implies `-t`. -l --long : Show object size of blob (file) entries. -z : \0 line termination on output and do not quote filenames. See OUTPUT FORMAT below for more information. --name-only --name-status : List only filenames (instead of the &quot;long&quot; output), one per line. Cannot be combined with `--object-only`. --object-only : List only names of the objects, one per line. Cannot be combined with `--name-only` or `--name-status`. This is equivalent to specifying `--format=&`#39`;%`(`objectname`), but for both this option and that exact format the command takes a hand-optimized codepath instead of going through the generic formatting mechanism. --abbrev[=] : Instead of showing the full 40-byte hexadecimal object lines, show the shortest prefix that is at least hexdigits long that uniquely refers the object. Non default number of digits can be specified with --abbrev=. --full-name : Instead of showing the path names relative to the current working directory, show the full path names. --full-tree : Do not limit the listing to the current working directory. Implies --full-name. --format= : A string that interpolates `%`(`fieldname`) from the result being shown. It also interpolates `%%` to `%`, and `%xNN` where `NN` are hex digits interpolates to character with hex code `NN`; for example `%x00` interpolates to \0 (NUL), `%x09` to \t (TAB) and `%x0a` to \n (LF). When specified, `--format` cannot be combined with other format-altering options, including `--long`, `--name-only` and `--object-only`. [ …​] : When paths are given, show them (note that this isn’t really raw pathnames, but rather a list of patterns to match). Otherwise implicitly uses the root level of the tree as the sole path argument. ## Output Format The output format of `ls-tree` is determined by either the `--format` option, or other format-altering options such as `--name-only` etc. (see `--format` above). The use of certain `--format` directives is equivalent to using those options, but invoking the full formatting machinery can be slower than using an appropriate formatting option.

<excerpt>What’s the recommended way to store files in Git? : While Git can store and handle any file of any type, there are some settings that work better than others. In general, we recommend that text files be stored in ... -8 without a byte-order mark (BOM ... ) endings. We ... BOM) in commit messages. ... With text files, Git will generally ensure that LF endings are used in the repository. The `core.autocrlf` and `core.eol` configuration variables specify what line-ending convention is followed when any text file is checked out. You can also use the `eol` attribute (e.g., `eol=crlf`) to override which files get what line-ending treatment. ... For example, generally shell files must have LF endings and batch files must have CRLF endings, so the following might be appropriate in some projects: ... ``` # By default, guess. * text=auto ... # Mark all C files as text. *.c text ... # Ensure all shell files have LF endings and all batch files have CRLF # endings in the working tree and both have LF in the repo. *.sh text eol=lf *.bat text eol=crlf</excerpt>

Compute bin sizes arithmetically instead of rebuilding each candidate prompt.

For every file and every open bin, packWhole copies the bin slice and calls promptWith, which rebuilds the whole prompt buffer (up to 120 KB). Files are sorted by decreasing size, so small files pass many full bins before one fits. Cost is O(files × bins × budget). On a whole-repo run with thousands of files and hundreds of bins, this copies hundreds of GB before any model call.

Keep a running byte count per bin. The added cost is: a separator (1 if the previous body is empty or does not end in \n), plus len(Path)+1+len(Body). Build each prompt once at the end.

⚡ Proposed change
-	var bins [][]File
+	type bin struct {
+		files []File
+		size  int
+	}
+	base := len(promptWith(instruction, nil))
+	cost := func(b *bin, f File) int {
+		n := len(f.Path) + 1 + len(f.Body)
+		if k := len(b.files); k > 0 {
+			prev := b.files[k-1].Body
+			if len(prev) == 0 || prev[len(prev)-1] != '\n' {
+				n++
+			}
+		}
+		return n
+	}
+	var bins []*bin
 	for _, f := range sorted {
 		placed := false
-		for i := range bins {
-			candidate := append(append([]File{}, bins[i]...), f)
-			if len(promptWith(instruction, candidate)) <= budget {
-				bins[i] = candidate

Make the node dependency explicit.

runPage runs exec.Command("node", ...) and calls t.Fatalf when node is missing. go test ./internal/sourcereview/... therefore fails on any machine without Node.js, even though the Go code is correct. Check exec.LookPath("node") first. If node is missing, skip the test unless an environment variable such as CI is set, in which case fail. The DOM proof stays mandatory in CI, and local runs stop breaking.

Make per-entry failures fail the run, or change the contract. The code and the goal file disagree.

The goal contract (metareview-whole-repo-source-review-goal.md Lines 113-124) says that an element that does not unmarshal fails the run and that a missing field fails the run. It also requires the path to be a kept file and the line numbers to exist in that file. Parse instead skips each such entry, writes a message to stderr, and Run then writes findings.json. The run exits 0 even when the model returned malformed or hallucinated entries. The wireEntry comment at Lines 15-17 still says "This command fails the run on that pointer", so the comment is stale. The progress file also reports these cases as "rejects".

Pick one behavior. To follow the contract, return an error for each case:

🐛 Proposed fix (follow the contract)
 		f, err := decodeEntry(raw)
 		if err != nil {
-			skipped = append(skipped, err.Error())
-			continue
+			return nil, nil, err
 		}
 		if err := f.Validate(); err != nil {
-			skipped = append(skipped, err.Error())
-			continue
+			return nil, nil, err
 		}
 		kept, err := resolveKept(f.File, files)
 		if err != nil {
-			skipped = append(skipped, err.Error())

-			skipped = append(skipped, fmt.Sprintf("line numbers do not exist in %s", f.File))
-			continue
+			return nil, nil, fmt.Errorf("line numbers do not exist in %s", f.File)
 		}

If skip-and-report is the intended behavior, update the goal contract, the wireEntry comment, and the progress file. Also, the internal/sourcereview/run_test.go "fails the run" tests do not cover a bad entry.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Stop accepting prose and trailing text around the findings object, or document the change.

The goal contract says: "When the body of that fence is the object, the parser uses the body. Any other extra text fails the run." extractFindings falls back to the first { that decodes as a findings object. It therefore accepts {"findings":[]} trailing, "The review follows.\n{...}\nThanks.", and an unclosed fence. TestParseRejects (internal/sourcereview/parse_test.go Lines 74-87) asserts this lenient behavior. An answer such as "I could not review this; example: {"findings":[]}" is recorded as a clean, empty review.

To follow the contract, remove the scan loop and return an error when objectText or findingsObject fails. Invert the test cases in internal/sourcereview/parse_test.go Lines 74-87 to match. If the leniency is intentional, record that change in the goal or architecture docs.

Resolve HEAD once and use that SHA for ls-tree and cat-file.

rev-parse HEAD, ls-tree -r -z HEAD, and readBlobs (HEAD:%s in internal/sourcereview/git.go Line 81) each resolve HEAD separately. If a commit or checkout happens between these calls, the reported commit does not match the reviewed content. The page and findings then name the wrong commit. Pass commit to ls-tree and to readBlobs, and format "<commit>:<path>".

Apply the path-only cuts before reading any blob.

readBlobs loads every blob at HEAD into memory. This includes vendor/, node_modules/, lockfiles, docs, and binary assets. cat-file --batch output is fully buffered by cmd.Output(), so a repository with large committed assets or vendored trees needs memory equal to the whole tree. Only utf8.Valid and isGenerated need the body. classify.Classify, claimcheck.IsTestPath, and vendored need only the path.

Split keepPath into a path check and a body check. Call readBlobs only for paths that pass the path check.

…the page

Grok call: `grok -p <prompt>` ran Grok's full agent. It cut the 120 KB prompt
to an excerpt and re-read it with read_file/grep: 11 model calls and 845K
input tokens for one hh prompt. Grok now runs as one turn with no tools:
--prompt-file --verbatim --json-schema --tools "" --max-turns 1
--no-subagents --disable-web-search --system-prompt-override. The prompt file
lives in os.TempDir() and is removed after the call.

Run: --jobs runs up to n prompts at once (default 8), keeping findings in
prompt order. --call-timeout (default 30m) kills a call and its process
group. Each finished prompt prints a progress line.

Line numbers: every prompt line now starts with its number and "| ", and
the instruction says to cite those numbers. Slices of large files number
from their original line, and the size limit counts the prefixes. On one hh
file (5 runs each) this cut Opus from 47 s to 29 s and Grok from 634 s to
540 s per prompt, with no fewer findings. Also fixes cutEnd reading one byte
past the end when the room exactly equals the bytes left.

Page: findings grouped by file, worst first, with the issue's first sentence
in each row; a severity bar and a map of where findings sit, both of which
filter; search; sticky controls; full-width layout; light and dark themes.

Also: ignore .claude/cost/, and add the Grok goal and its progress file.

Cancel the review context on SIGINT and SIGTERM.

CLI currently runs the review with a context derived from context.Background() and installs no signal handler. A signal can terminate metareview before the context is canceled. The per-call timeout runs in that process, so it cannot kill detached CLI groups after the process exits. These children can run beyond 30 minutes, and Grok prompt cleanup defers do not run.

Pass a signal-aware context through Options:

Suggested fix
-	ctx, cancel := context.WithCancel(context.Background())
+	parent := opts.Context
+	if parent == nil {
+		parent = context.Background()
+	}
+	ctx, cancel := context.WithCancel(parent)
 	defer cancel()
// Options: add
Context context.Context

// CLI:
ctx, stop := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
defer stop()
err = Run(Options{Context: ctx, /* ... */})
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
ctx, cancel := context.WithCancel(context.Background())

`source-review` only reviewed a whole checkout, so any measurement meant an
hour-long run or a fixture repo. --path limits the review to the kept files at
that path or under that directory, and repeats to add more. It runs the real
selection, prompt, call, and parser on the real repo; it only narrows which
kept files are sent. A --path that matches no kept file (a typo, a partial
name, or a file the source cut dropped) fails the run before any model call.
Grok ran locked down (one turn, no tools, our system prompt, a findings JSON
schema) while Opus and Astra ran on their CLI defaults, so the comparison was
not like for like. Every model now gets the same system prompt and the same
findings schema, with tools off:

- claude -p: --tools "" --system-prompt --json-schema --strict-mcp-config
  --no-session-persistence
- grok: unchanged (--prompt-file --verbatim --json-schema --tools ""
  --max-turns 1 --no-subagents --disable-web-search --system-prompt-override)
- codex exec: -s read-only --ephemeral --output-schema <temp file>. Codex has
  no switch to remove its tools or replace its system prompt, so it is the one
  model that differs.

The schema now sets "additionalProperties": false on every object; Codex's
strict schema mode rejects it otherwise (HTTP 400 invalid_json_schema).

A real --path web/src/routes/DirectDeposit.svelte run on hh, one per model,
finished cleanly: Opus 24 s / 4 findings, Astra 52 s / 2, Grok 426 s / 7.

<excerpt>&gt; Reference for Claude Code hook events, configuration schema, JSON input/output formats, exit codes, async hooks, HTTP hooks, prompt hooks, and MCP tool hooks. ... Hooks are user-defined shell commands, HTTP endpoints, MCP tool calls, LLM prompts, or subagents that execute automatically at specific points in Claude Code&`#39`;s lifecycle. Claude Code fires the same hook events wherever it runs: sessions in the terminal, IDE extensions, the Desktop app, and Claude Code on the web. Use this reference to look up event schemas, configuration options, JSON input/output formats, and advanced features like async hooks, HTTP hooks, and MCP tool hooks. ... The Configuration section ... the full schema, and each hook event section documents what input your command receives and what output it can return ... Claude Code sends the ... input as the POST request body with `Content ... json`. The response body uses the same JSON output format as command ... ## Hook input and output ... Command hooks receive JSON data via stdin and communicate results through exit codes, stdout, and stderr. HTTP hooks receive the same JSON as the POST request body and communicate results through the HTTP response body. This section covers fields and behavior common to all events. Each event&`#39`;s section under Hook events includes its specific input schema and decision control options. ... Exit code output ... command tells Claude Code whether the action should proceed, ... from stdout on every exit code, not just 0, ... events that use the ... validation takes effect alongside the code ... can&`#39`;t override ... ### JSON output ... Exit codes only let you block or stay silent, but JSON output gives you finer-grained control. Instead of exiting with code 2 to block, exit 0 and print a JSON object to stdout. Claude Code reads specific fields from that JSON to control behavior, including decision control for blocking, allowing, or escalating to the user. ... Choose one approach per hook: either use exit codes alone for signaling, or exit 0 and print JSON for structured control. If you mix them, exit 2 keeps its blocking effect, and Claude Code still reads the JSON fields, with the one elicitation exception noted under Exit code 2. ... Hook output strings, including `additionalContext`, `systemMessage`, and plain stdout, are capped at 10,000 characters. Output that exceeds this limit is saved to a file and replaced with a preview and file path, the same way a large valid Bash result is handled under Output limits. ... The JSON object supports three kinds of fields: ... - Universal fields like `continue` are listed in the table below. Every event accepts them, but some events discard them or deliver `systemMessage` somewhere other than the transcript. Each event&`#39`;s section says so. `terminalSequence` works on those events too, with the exceptions listed under Emit terminal notifications. - Top-level `decision` and `reason` are used by some events to block or provide feedback. - `hookSpecificOutput` is a nested object for events that need richer control. It requires a `hookEventName` field set to the event name. ... | Field | Default | Description | | --- | --- | --- | | `continue` | `true` | If `false`, Claude stops processing entirely after the hook runs. Takes precedence over any event-specific decision fields | | `stopReason` | none | Message shown to the user when `continue` is `false`.

Read Claude’s structured_output for --json-schema.

When the opus branch passes --json-schema, Claude Code returns the schema-constrained object in structured_output. claudeModelText reads only result, so a valid response with no usable result returns missing model text and aborts the review.

Parse and marshal structured_output before falling back to result. Update TestCallShapes to use the schema-constrained envelope.

Reject an empty --path before cleaning it.

When a caller passes --path "", path.Clean returns ".". onlyPaths then reviews every kept file instead of rejecting the unmatched path. Check for an empty value before path.Clean, so an accidentally empty path cannot expand the review scope.

baseline in the same batch:

  default effort: 623 s, 6.4 findings, 2.8 of 3 core bugs
  medium effort:  502 s, 7.8 findings, 3.0 of 3 core bugs

19% faster with no lost findings. Low effort stays out: it is faster still but
loses findings.

2. Bigger prompts: raise `MaxPromptBytes` so S2 packs into about a quarter
as many prompts. Measure Grok on S2 with `--jobs 1`, and Opus on S2.
Also record findings per prompt. First check that Grok accepts a prompt
that large; if it rejects it, record the CLI's error and pick the largest
size it accepts.

Hi @benkruger, thanks for this. It's substantial and careful work. The Grok measurements in particular are exactly the kind of evidence we wish more PRs came with: the grok -p agent trap, the one-shot call shape, and the side-by-side effort, schema and prompt-size experiments. Here's what we did with it, and why.

What we did

  • Read your goal, progress and commit files to pin down the intent. The PR description is empty, so these were the only source. A second reviewer then checked our summary against them.
  • Reviewed the code closely from three angles: correctness, security, and fit with metareview's design.
  • Ran the full make cover gate locally on the PR head, with the CI-pinned golangci-lint v2.13.1.
  • Checked each of CodeRabbit's 14 open threads against the code.
  • Checked whether metareview's existing machinery can already do part of this. It can: a whole-repo review works today through the sharded gates, by reviewing from an empty base commit to a commit with HEAD's tree. On this repo that produced 315 shard packs in 37 s with no model calls, and about 27 with your first-party cut applied.

Why we wrote #167 instead of asking you to reshape this PR

As we read it, your goals are:

  1. a whole-repo, first-party source review;
  2. a fair way to choose between and benchmark Opus, Astra and Grok as reviewers;
  3. a readable report;
  4. making Grok work as a one-shot reviewer.

Most of that can be delivered inside metareview's existing design, instead of as a parallel subsystem:

  • the sharded gates already handle over-size input and record the run in the normal review history;
  • internal/fsm/judge already has claude-cli/ and codex/ transports with retries, effort checks and typed errors;
  • the lens finding contract is already lensoutput.TypedFinding.

#167 has the full plan, starting with our summary of your intent; please correct anything we got wrong. In brief:

  • W0: isolate the model CLIs from the reviewed repository (below).
  • W1: a full grok/ judge transport, built on your measured call shape, usable everywhere a judge is.
  • W2: review task-done --whole-repo.
  • W3: an opt-in --source-only filter lifted from your select.go.
  • W4: a discovery judge kind plus a review shards run --reviewer <model> driver, which is what makes the model choice work, and single-model and unattended runs too.
  • W5: review shards compare for benchmarking, including a precision check. Your S2 result, with Grok at about 3.4× Opus's finding count, is interesting and worth adjudicating.
  • W6: your HTML page, rendered from our result files.

Findings on the PR as it stands (detail on request):

  • Security (blocking): the model CLIs run with the reviewed repository as their working directory. In headless mode they can still load that repository's project-level configuration, and turning off tools doesn't switch that off, so reviewing an untrusted checkout isn't isolated. Our own claude-cli/ judge has the same exposure; that's W0, and we're fixing it on our side.
  • Codex: under -s read-only it keeps a shell that can read the disk, so hostile repository content could steer it into putting local file contents into findings. It needs the same isolation.
  • Parsing differs from the goal file: bad entries are skipped rather than failing the run, and prose around the {"findings":…} object is accepted. So a refusal that happens to quote an example reads as "no bugs".
  • No SIGINT/SIGTERM handling: Ctrl-C leaves up to --jobs model CLIs running and billing, plus prompt temp files that contain source.
  • CI would be red: golangci-lint reports 13 errcheck issues (fmt.Fprintln in run.go).
  • Files that shouldn't ship: the six root-level goal/progress files (they carry local paths and session ids), bin/ci, and the .gitignore line.
  • CodeRabbit: about 10 of the 14 threads are valid. The main ones are the parse contract, signal handling, NUL-safe cat-file, filtering before reading blobs, and the node dependency in page_test.go. The structured_output one isn't needed, because result already carries the JSON.

Where you could help, if you're up for it

  • The grok/ transport (W1), since you have the call-shape knowledge.
  • The first-party filter (W3), which is essentially select.go and its tests.
  • The report page (W6).

Each would be a small focused PR against current main (0.13.2). We'll take W0 now, since it affects released code.

We'd also value your view on #167's open questions:

  • should whole-repo runs gate or report?
  • shard size: your data suggests smaller prompts find more;
  • review shards run versus an FSM workflow for the driver.

It would also help to know whether you intended this for upstream or mainly for your own benchmarking. The goal files don't say.

We're not closing this PR. It's a useful reference while the pieces land. Let us know how you'd like to proceed.

…iew (#168)

* fix(judge): run judge CLIs in an isolated directory, not the reviewed repo

The claude-cli/ and codex/ judges started the model CLI in metareview's own
working directory, which is normally the repository under review. A headless
CLI still loads that directory's project configuration without the interactive
trust prompt, and disabling tools does not switch it off, so reviewing an
untrusted checkout (a fork's PR branch) was not isolated from it. Verified
offline: under 0.13.2, `fsm judge --model claude-cli/...` run inside a repo
carrying project hooks fired them; with this change it does not.

- Every attempt runs in a fresh, empty, 0700 temp dir (judge.isolatedDir),
  removed after the call; if one cannot be made the attempt fails as a
  transport error and nothing is spawned.
- claude: --setting-sources user --strict-mcp-config (not --bare, which skips
  the keychain and so the OAuth session).
- codex: -c project_doc_max_bytes=0, covering the escalation path's
  materialized tree, which is still honoured as an explicit work dir.

* fix(judge): user-private judge dirs, deferred cleanup, no session persistence

From the self-review of e30a904:
- Create judge dirs under os.UserCacheDir (0700 base) instead of a shared temp
  dir: codex walks up to a .git root and loads repo-scoped skills, which on a
  multi-user host with TMPDIR unset another user could plant in /tmp. The temp
  dir remains the fallback when there is no cache dir.
- Defer the directory cleanup so a panic in the exec seam cannot leave it.
- claude --no-session-persistence and codex --ephemeral: a judge call is not a
  session, and a fresh dir per attempt would otherwise leave one transcript
  (carrying the full prompt and diff) per call. Verified offline: no .jsonl
  transcript is written.

Hi @benkruger, thanks for the Oct 3 round — we re-reviewed at e8c6560.

What stood out, and we mean it: the Grok work is the best part of this PR. The grok -p agent trap, the one-shot flag set, effort parity with Opus, line-numbered prompts, and the keep/drop discipline (≥10% faster, ≤0.5 findings lost, core bugs intact) are exactly the evidence we wish more PRs carried. We also noticed the fixes since the last review — temp-workspace isolation, HEAD pinned once, NUL-safe cat-file, filter-before-read, SIGINT/SIGTERM, atomic publish. All good.

Mechanically it's nearly green: go test, go vet, gofmt, shellcheck and the coverage gate all pass (100% on sourcereview). The only red is 13 errcheck findings in run.go. We're happy to fix those with you, or push them directly — your fork allows it.

But here's the part we owe you straight: the command is a second review engine. It deliberately bypasses the typed lens contract and the anchor gate, and re-implements the judge runner internal/fsm/judge already has. For a tool whose whole promise is "findings are validated before they count," that's the one thing we can't take as-is — it's a product invariant, not a critique of your code. We'd also be re-solving sharding, state and reporting that already exist, and the tool can't do incremental review.

And the thing we had to be honest with ourselves about: whole-repo review already works in metareview today — an empty root base commit plus the existing sharded gates — and it records into runs.jsonl/FINDINGS.md and supports --base last-reviewed. So the "review a whole repo" deliverable is covered. Your PR's real novelty is elsewhere.

What only your PR does (what we want):

  1. A model that discovers, headless — today discovery is the agent's subagent lenses, and judges only adjudicate. (Whole-repo review, model-selectable reviewers and a grok/ judge: a metareview-native path for #165's intent #167 → W4)
  2. Fair model benchmarking — same job for every model, side by side, with recall against seeded bugs. (W5)
  3. The first-party source cut with a kept/dropped preview. (W3)
  4. The offline HTML report. (W6)
  5. The Grok call shape as a real judge transport, usable everywhere a judge is. (W1)

The invitation: #167 (written after your PR) is our plan for exactly this. W1, W3 and W6 are small, mostly lift straight from your code, and are yours if you want them — we'd open them as focused PRs against current main and credit you, or you can take one. That gets your knowledge upstream without either of us unwinding a second engine later.

One open question, and no wrong answer: was this meant for upstream, or mainly your own benchmarking? Your goal files said "do not commit, push, or open a PR," so we don't want to assume.

A suggestion: what a PR we'd merge would look like

To make this concrete, here's the shape we'd accept — and it's smaller than it sounds, because we already have the engine. A whole-repo review works today (an empty-root base commit plus the existing sharded gates), and it records into runs.jsonl/FINDINGS.md and supports --base last-reviewed. So the missing pieces are the four things only your work does, each as a focused PR against current main:

A PR we can take has:

  1. The right home. It extends the existing layers — a judge transport, shardpack, the typed lensoutput contract — instead of a parallel runner/parser/reporter. That is the one thing we can't take as-is in the current PR: a second engine that bypasses the anchor gate and the typed contract.
  2. The isolation invariants kept: an empty isolated working directory; one turn, no tools, our system prompt, no user hooks/plugins; the prompt never in argv (a private file, removed after the call); a per-attempt deadline with process-group kill; the same retry ladder and typed errors as the other transports.
  3. The typed contract end to end: lensoutput.TypedFinding + ValidatePayload, with malformed output failing closed — not skipped, and never read as "no findings."
  4. Real token accounting, so a run trips budget/max_iterations like the others do.
  5. The repo's gates: make cover green (100% coverage on the touched packages) and the pinned golangci-lint clean, run locally — our CI does not run on a fork PR, so we can't see it for you.
  6. Small and described: one workstream per PR, against current main, with the intent and the verification commands in the description. No root goal/progress files, no bin/ci.
  7. A live smoke behind -tags smoke (W1's done-when), because a couple of Grok facts can't be read off the docs and can only be settled by running it.

We've sketched W1 to show the shape we mean, and we're happy to share or push it as a starting point — take it, rewrite it, or ignore it; W1 stays yours. #167 is the plan if you want the full detail.
