Development

Install dependencies

npm install

npm install installs the repo hook path. .githooks/pre-commit runs npm run precommit, and .githooks/commit-msg enforces Conventional Commits 1.0.0.

Do not use git commit --no-verify or any equivalent bypass.

Run checks

Full precommit suite:

npm run check

This runs:

• docs checks with docs:check: generated surface-reference freshness, generated code-map freshness, internal docs links/sidebar routes, packaged Markdown links, GitHub Pages base-prefixed docs links, and docs-site build
• formatting with oxfmt
• type-aware linting with oxlint
• tsgo typecheck
• Vitest suite

Critical-path coverage gate:

npm run check:coverage

Secondary TypeScript compiler check:

npm run typecheck:tsc

Useful targeted checks:

npm run format
npm run lint
npm run typecheck
npm test
npm test -- tests/queue.test.ts

Run Pi locally

pi -e ./extensions/index.ts

Or install the checkout path:

pi install /path/to/pi-hindsight

Documentation architecture

Use docs/documentation-architecture.md as the migration map for documentation-site work, navigation changes, generated reference placement, and archive decisions.

Work tracking

Use GitHub Issues as the project task ledger. Backlog items, current work, blockers, decisions, and follow-ups should be visible in issues or issue comments. Do not rely on local scratch files, chat-only plans, or private harness TODOs as the source of truth for project work.

When a report or review creates actionable work, turn accepted items into issues and remove or archive the scratch file after the issues carry the work.

Coverage gates

Critical-path coverage thresholds are configured in vitest.config.ts for:

• queue
• queue lock
• JSONL queue store
• import Modules
• config Modules
• lifecycle Modules
• transport Modules

Live smoke

For memory-path behavior changes, prove the live path with a configured Hindsight server:

export HINDSIGHT_BASE_URL=http://localhost:8888
# export HINDSIGHT_API_KEY=... # if needed
npm run smoke:hindsight

The GitHub Hindsight Integration workflow also runs live smoke when configured. An unconfigured workflow skip is not proof for memory-path changes.

Source-of-truth order

1. Official Hindsight docs and API behavior
2. Official Pi extension/session/package docs
3. This repository’s PRD, plans, ADRs, CONTEXT.md, AGENTS.md, and CONTRIBUTING.md
4. Public reference repos as implementation inspiration only
5. User notes and gists as hypotheses only

Definition of done

A change is done only when:

1. it follows official Hindsight memory rules;
2. it uses documented Pi extension hooks;
3. tests cover changed logic;
4. user-visible behavior is documented if changed;
5. the diff is minimal and focused; and
6. no new memory anti-pattern is introduced.

Changelog and releases

CHANGELOG.md is generated from Conventional Commits. The normal release path is release-please: it opens a release PR that updates version metadata and the changelog, then creates the tag and GitHub release after merge.

Local fallback:

npm run changelog

The version script also regenerates and stages CHANGELOG.md during npm version. Use these scripts for inspection or emergency manual releases, not as the normal source of truth. Do not hand-edit generated release entries as the source of truth.
