AgentDir

Use AgentDir as the local flight recorder for coding-agent work in this repository.

The engineer should not have to run AgentDir commands during normal coding work. The agent owns the background recording flow:

• Before starting work in an unfamiliar checkout, run agentdir root --require --quiet. Exit 0 means an initialized local or shared worktree store is ready; do not decide whether AgentDir is set up from the presence of .agentdir in this checkout.
• If the probe exits 3, run agentdir adopt --if-needed --gitignore user. If hook installation is blocked in a restricted linked worktree, rerun it with --no-hooks.
• Then start non-trivial coding work yourself with agentdir work start "<subsystem: distinctive behavior or constraint>". Keep the title concise but retrieval-specific: name the subsystem plus a distinctive behavior or constraint, preserving request terms likely to match prior work.
• Retrieval is automatic. Configured FastEmbed stores use fused semantic and lexical matching; other stores keep the built-in hybrid path. Use the default invocation without a retrieval flag during normal work.
• Read the printed context briefing, re-opening it with agentdir work context --show when the original output is unavailable. Treat briefing excerpts as previews. Prefer the printed agentdir work context --pack <pack-id> --expand <number> command before marking a source used when implementation details, prior patterns, or exact evidence matter. Expansion is optional and does not replace the terminal review decision.
• After reading and any useful expansion, close the review once. Repeat --use in that command for every useful numbered source: agentdir work context --use <number> [--use <number> ...] --reason "<how they help>", or record a reasoned agentdir work context --none-relevant --reason "<why>" decision. Use --skip --reason "<why>" only when review is impossible; no decision is needed when the briefing presents no sources.
• Run evidence-bearing commands through agentdir run -- <command>.
• Evidence-bearing commands include tests, lint, typecheck, build, release checks, reproduced failures, and diagnostics that support final claims.
• Do not wrap routine exploration commands such as rg, sed, nl, cat, ls, find, or quick read-only git status checks.
• Use agentdir status for a single view of session, evidence, memory, context, registered roots, and doctor health.
• Use agentdir evidence --brief and agentdir timeline to skim recorded work.
• Record each verification the final response relies on with agentdir claim <family> --passed|--failed, e.g. agentdir claim test --passed. Families: test, lint, typecheck, build, doctor, release.
• Record failures as failures. A claim that overstates a result is reported as contradicted; an honest failure claim is acknowledged.
• Re-recording a family replaces its earlier claim; withdraw one made in error with agentdir claim <family> --retract.
• Use agentdir audit session and agentdir audit claims before final claims when evidence support matters.
• Before the final response, run agentdir work finish --json --brief when practical. Use agentdir report final --format json to preview the same agent handoff without ending the session.
• Read the agent_handoff object before making final verification claims.
• Do not record secrets, private keys, raw environment dumps, or credential-bearing command output.
