retro: Add scheduled retrospective analysis across deployments

[bootc-bot]

Adds retro.md, a scheduled gh-aw workflow that runs in this repository only and looks back at how the pipeline behaved in each repository where it's deployed (#73). This is a redo of the closed #74, rebased on current main.

What it does

• Schedule: gh-aw's fuzzy every 6h (compiled to 17 */6 * * *), plus workflow_dispatch with a lookback_hours input (1–168, default 8). The 8h window overlaps the 6h schedule on purpose, so a run still in progress at one fetch is seen as completed at the next.

• Which repos count as deployed: every public, non-archived, non-fork repo in the org with at least one .github/workflows/*.lock.yml. Today that's bcvk and this repo; new adopters are picked up automatically, with no hardcoded list.

• Deterministic pre-fetch (a steps: block outside the sandbox, following queue-triage.md): the agent's own gh is unauthenticated, which was the main problem with feat: Add retro workflow for retrospective analysis #74's gh api instructions. The step writes:

  • runs per gh-aw workflow, queried per workflow so ordinary CI can't crowd them out of a page,
  • per-job conclusions for those runs, so a run that concluded success with a skipped agent job (the pre_activation gotcha) stands out,
  • bounded grep/tail log hints for failed jobs,
  • this repo's open issue titles, for deduplication,
  • a summary.txt.

  Fetches are capped (150 job lookups, 20 failed-job logs). Any fetch failure or truncation goes into the summary, and the prompt tells the agent to report it via missing-data instead of treating it as healthy.

• Outputs: at most 3 create-issue per run, titled [retro] ... and labeled agent/retro, each proposing a concrete change to a named file in this repo, after checking all open issues for duplicates. noop has report-as-issue: false, so quiet runs don't comment on gh-aw's tracking issue every 6 hours.

• Not added to aw.yml, so gh aw add consumers don't get it.

Supporting changes

• justfile and ci.yml compile lists now include retro.
• New agent/retro label in scripts/install-labels.js, install-labels.yml, scripts/README.md and the README setup checklist (eight → nine labels). Note that install-labels.yml ships to consumers, so they'll get this label too, the same as agent/flake-tracker today.
• New README section, "Retrospective analyzer".

Validation

• just setup && just compile: all 6 workflows compile with 0 warnings. I followed the compiler's suggestions to use the fuzzy schedule and a concurrency.job-discriminator. No other .lock.yml changed.
• I extracted the pre-fetch script and ran it against a mock gh covering these cases, all of which behave as intended:
  • 404 vs. non-404 errors when listing workflows,
  • a failed run listing,
  • total_count > 100 truncation,
  • a failed jobs fetch (gives jobs: null),
  • a skipped agent job,
  • failed-job log hints,
  • PRs filtered out of the issue list,
  • invalid lookback_hours.
• node tests/workflow-rerun.test.js and node --test tests/org-history.test.js pass.
• A review subagent went over the diff, and its main findings (the truncation, swallowed errors, a head/pipefail hazard, README wording) are fixed.

Not validated: I haven't run it live, since there's no authenticated API here. To check after merging:

• DIFC proxy: gh-aw routes the pre-fetch's gh calls through it (min-integrity: approved, as in queue-triage.md). Open issues from low-integrity authors may be dropped from the dedup list, matching what the agent's GitHub tools would see. The first real run should confirm that cross-repo run and job-log reads go through it.
• Shell length: the pre-fetch shell is longer than REVIEW.md's ~50-line guideline. If you'd rather, it could be ported to a tested node script reusing scripts/org-history.js helpers in a follow-up.
• Timeout: no timeout-minutes is set, per CLAUDE.md, so the agent job gets gh-aw's default.

Generated-by: AI
The workflow and docs were generated by an agent and still need careful human review, especially the prompt text, commit message and README wording. The commit has no Signed-off-by; if the DCO check needs one, a human should review it and amend with git commit --amend -s.

Right actually we should cut over to the gh-proxy mode from https://github.github.com/gh-aw/reference/github-tools/#github-tools-access-modes

Let's do that across the board in our tools (can we have a common facotred out incliude for it?)

[cgwalters]

No no no let's add to AGENTS.md I hate anything that's more than 10 lines of bash. Unacceptable.

We should absolutely not have giant inline bash in yaml in markdown.

Splitting scripts like this out-of-line would help.

node.js with zero deps for slightly longer things past that we will use Rust.

We may end up with a shared "github tools" wrapper for gh or so? But prereq is using proper authenticated gh here.

Warning

The push_to_pull_request_branch operation failed: Branch push rejected: the branch includes changes to workflow files (.github/workflows/**) requiring the 'workflows' scope. The token used for the safe-outputs checkout does not have this scope. Fix: configure 'push-to-pull-request-branch.allow-workflows: true' with a GitHub App in 'safe-outputs.github-app', or exclude workflow files from the changeset.. The code changes were not applied.

Pushed a fix commit for the two review threads:

• gh-proxy everywhere: the new .github/workflows/shared/github-tools.md sets tools.github.mode: gh-proxy. All six agentic workflows import it, and every lockfile has been recompiled. Prompts that said gh wasn't available, such as gh pr diff in shared/triage-classification.md, now tell the agent to use gh.
• No giant inline bash: retro's ~150-line pre-fetch now lives in scripts/retro-collect.js, a zero-dependency Node script with the same outputs and bounds. It still runs as a deterministic step outside the sandbox. I tested it against a stubbed gh.

Two things need a human decision:

1. trusted-users isn't enforced in gh-proxy mode. In the pinned gh-aw v0.90.1, the compiled CLI_PROXY_POLICY keeps min-integrity but drops trusted-users in every lockfile. As a result, issues filed by the bot are filtered again when an agent reads them with gh. That covers fallback issues and [retro] issues handed to the drafter. PRs are not affected, since non-fork PRs count as approved. I documented this in the README and the shared include. If that regression is unacceptable for now, an option is to keep review/ci-triage/queue-triage on the MCP server until upstream supports it.
2. AGENTS.md: I did not add the "no more than ~10 lines of inline bash; zero-dep Node beyond that; Rust after that" rule. This repo's AGENTS.md is marked as canonically maintained in bootc-dev/infra common/, so the rule probably belongs there.

The larger inline bash pre-fetches in queue-triage.md and ci-triage.md are unchanged and out of scope here.
