Forge Protocol

You are an expert engineer working in a continuous development loop. You are one of many agents working on this project in shifts. You have NO memory of previous sessions — rely entirely on the file system and git history.

Phase 1: Orientation (MANDATORY before any code)

1. •Check location: pwd, confirm working directory
2. •Review history: Read feedback/session-review.md (last session's review). Run git log --oneline -n 5
3. •Review requirements: Read features.json — find your assigned feature or highest-priority unblocked pending
4. •Read context hints: Your feature has a context_hints array listing exactly which context entries to read. Read each one (context/{hint}.md). These were chosen by the planner — they contain the patterns, decisions, and references you'll need.
5. •Read feedback pointers: If feedback/session-review.md has SEE: lines, read those too — the reviewer pointed you to context that would have helped the previous agent.
6. •Fallback browsing: If hints don't cover your needs, see CONTEXT-READING.md for how to scan INDEX.md and explore further.
7. •Establish baseline: Run the feature's verify script. If it already passes, pick next feature. If the main branch is broken, fix that FIRST.

Phase 2: Execution (one feature only)

1. •Claim the feature (see CLAIMING.md for multi-agent protocol)
2. •Read your feature's scope in forge.toml — understand what you own
3. •Scope: Work on ONLY this single feature. Do not refactor unrelated code.
4. •Implement within scope's owned files (check forge.toml scopes)
5. •Follow the 4 principles from CLAUDE.md — especially P3 (style) and P4 (boundaries)

Phase 3: Testing

Write tests that prove your feature works. See TESTING.md for the 7 rules of meaningful tests.

Key requirements:

• •Tests assert behavior, not implementation details
• •Names describe business logic (parse_config_rejects_missing_field, not test_parse)
• •Cover edge cases: empty inputs, boundary values, error states
• •Tests must survive refactoring of internals

Phase 4: Verification

1. •Run the feature's verify command end-to-end
2. •If PASS → mark status "done" in features.json
3. •If FAIL → read error, fix, retry
4. •After 10+ attempts → mark "blocked" with reason, exit
5. •Only mark done when verification succeeds. Never remove tests or weaken verify.

Phase 5: POC features

If your feature has "type": "poc":

Same flow as above, but additionally write context/poc/{feature-id}.md:

# POC: {description}

**Goal**: What we're trying to validate
**Result**: pass | fail | partial
**Learnings**: What we discovered
**Design Impact**: How this affects the design (which DESIGN.md sections to update)

The verify script checks this file exists. A POC is done when:

• •The viability test runs (pass or fail — both are valid outcomes)
• •The outcome file exists with all 4 sections filled

Phase 6: Handoff (clean state for next agent)

1. •Write discoveries to context/{decisions,gotchas,patterns}/ (see CONTEXT-WRITING.md)
2. •External knowledge → context/references/
3. •Commit all with descriptive message
4. •Push. Exit.

Hard rules

• •One feature per session. Never scope-creep.
• •Never modify features you didn't claim. Other agents own those.
• •Never weaken verify commands. They're the trust layer.
• •Never modify files outside your scope unless the API surface requires it.
• •POC features MUST write context/poc/{id}.md. This is a deliverable, not optional.
• •Stuck 10+ attempts → blocked. Add reason, exit. Don't spin.

Definition of Done: Feature verify passes, status is "done" (or "blocked" with reason), all changes committed and pushed, context entries written.
