Adds eslint.config.mjs using typescript-eslint's recommended config scoped to src/**/*.ts. Runs `npm run lint` (eslint src) successfully; 271 pre-existing violations (mostly no-explicit-any) are intentionally left unfixed and tracked in docs/eslint-baseline-followup.md as follow-up work, per ticket scope. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds .github/workflows/ci.yml running npx tsc --noEmit, npm run lint, npm test, and npm run build in order on PRs against main. Also fixes a real `npm run build` break: tsup's DTS build failed to resolve types for the optional peer deps `@ai-sdk/openai` and `ollama-ai-provider` (not installed, per peerDependenciesMeta). Added typings/optional-peers.d.ts with minimal ambient module declarations, included via tsconfig.json, so the declaration build succeeds without requiring consumers/CI to install those optional packages (avoids pulling in a live-network-dependent test path that surfaced when the real packages were tried as devDependencies instead). Verified locally: tsc --noEmit exits 0; lint exits 1 with only the 271 baseline violations tracked in LOU-B1; test exits 1 with the 3 known pre-existing provider suite failures (missing optional peer deps) and all 457 other tests passing; build exits 0.

Adds the GitHub Actions CI badge under the top-level heading, pointing at LinuxDevil/agent-sdk's ci.yml workflow (repo confirmed via package.json's repository field). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Fixes test:coverage to run non-watch (vitest run --coverage instead of vitest --coverage, which hung in watch mode locally). Measured baseline coverage (excluding the 3 provider suites that fail to load here due to missing optional peer deps, see LOU-B2): statements 62.81%, branches 84.52%, functions 73.36%, lines 62.81%. Sets vitest.config.ts coverage.thresholds 1-2 points below each, rounded down: statements 61, branches 83, functions 72, lines 61. CI now runs `npm run test:coverage` instead of `npm test` so the threshold gates every run. Verified enforcement: temporarily removed src/flows/FlowExecutor.test.ts, coverage dropped to ~57% and the run exited non-zero on the threshold breach; restored the file and the run passed again at baseline.

Grep of src/ confirmed zero references to either dotenv or dedent, so both were unused dependencies. Removed from package.json and regenerated the lockfile. Verified npm run build and npx vitest run still pass (same baseline: 457 tests passing, 3 known pre-existing provider suite failures from missing optional peer deps).

Moves src/providers/OpenRouterProvider.examples.ts to the top-level examples/ directory so it isn't bundled into the published package. Updated its relative import from '../index' to '../src/index' to account for the new location. package.json's files array was already dist-scoped (dist, README, LICENSE, CHANGELOG, CONTRIBUTING) with no examples entry. Verified: npx tsc --noEmit and npx vitest run pass at the same baseline, and `npm pack --dry-run` output has zero "examples" matches. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The package has no createMockRepositories factory; the actual mocks.ts
exports are five Mock*Repository classes (MockAgentRepository,
MockSessionRepository, MockResultRepository, MockMemoryRepository,
MockAttachmentRepository). Removed their re-export from
src/data/index.ts so they're no longer reachable from the package
root or the ./data subpath.
Added tsup.config.ts entry `data/mocks: src/data/mocks.ts` so it
produces its own dist output, and a new `./testing` subpath in
package.json's exports map pointing at dist/data/mocks.{js,mjs,d.ts},
matching the existing entries' dist shape.
Added a CHANGELOG.md entry under Unreleased/Changed documenting the
breaking change and the real symbol names (adjusted from the ticket's
assumed `createMockRepositories` name, which doesn't exist in this
codebase).
Verified via a scratch script (not committed): dist/index.js,
dist/index.d.ts, dist/data/index.js and dist/data/index.d.ts have zero
occurrences of MockAgentRepository; requiring dist/data/mocks.js
exposes a working MockAgentRepository with functional create/findById/
update/delete methods. npx tsc --noEmit and npx vitest run remain at
the same baseline (457 passing, 3 known pre-existing provider
failures).

…thresholds
src/providers/OllamaProvider.test.ts, OpenAIProvider.test.ts and
OpenRouterProvider.test.ts fail to even load (Vite "Could not resolve
ollama-ai-provider/@ai-sdk/openai" errors) because those optional peer
deps aren't installed. That collection failure aborted vitest before
it ever reached the coverage report / threshold-check step, so
`npm run test:coverage` silently produced no report and enforced
nothing.
Add vitest.coverage.config.ts, a coverage-only config that extends the
base config and excludes exactly those 3 spec files from test
collection (vitest 1.6.1's CLI --exclude flag does not support being
passed multiple times or comma-separated, so this had to go in a
config file rather than a script flag). test:coverage now points at
it. `npm test` / `npx vitest run` are untouched and still run all 31
suites, so the 3 known failures stay visible there.
Installing the peer deps as devDependencies was considered instead,
but OpenRouterProvider.test.ts was previously reported to start
making real network calls once @ai-sdk/openai resolves, so exclusion
is the safer fix.
Verified: npm run test:coverage now completes (exit 0), prints the
coverage summary table, and writes coverage/coverage-final.json and
the HTML report. Hiding src/execution/MemoryManager.test.ts and
rerunning fails for the right reason ("Coverage for functions
(70.46%) does not meet global threshold (72%)", exit 1); restoring it
brings coverage back to a clean pass (exit 0).

…t permanently red The 270 pre-existing violations tracked in docs/eslint-baseline-followup.md were all errors with no suppression, so npm run lint always exited non-zero and CI's lint step would fail on every future PR regardless of what it touched. Downgrades no-explicit-any/no-unused-vars/ban-ts-comment to warn, matching the epic's stated "sane baseline, iterate later" intent — new *errors* still fail CI, existing warnings are visible but don't block.

Summary
Implements all 7 tickets from LOU-B (Phase 0), standing up CI/engineering foundations:

(Note: the ticket referenced acreateMockRepositoriesfactory function that doesn't exist in this codebase; adapted to the real exported classes.)Validation results
Implemented in an isolated worktree, independently QA-verified by a fresh agent from a clean state. QA caught one genuine bug:
test:coveragenever actually produced a coverage report because the 3 known-broken provider test suites aborted vitest's collection phase before coverage/threshold checking ran — fixed with a coverage-only vitest config excluding just those 3 spec files from collection (not fromnpm test, which still surfaces them). Enforcement re-verified after the fix: hiding a real test file drops functions coverage below threshold and fails the build (exit 1, genuine threshold error); restoring it passes cleanly (exit 0).npx vitest run: 457 passing, 3 known pre-existing provider-suite failures (missing optional peer deps@ai-sdk/openai/ollama-ai-provider) — unrelated to this epic.npx tsc --noEmit: clean, exit 0.npm run build: exit 0.npm run test:coverage: exit 0, coverage 62.65%/84.43%/73.17%/62.65% (stmts/branches/funcs/lines), all above configured thresholds.Notes
CI's test step will typically show non-green from the 3 known peer-dep suites — this is expected and documented, not a regression introduced here.
