Update Practices

3-phase pipeline to keep dotforge up to date with discovered practices.

Practice sources:

• Post-session hook (detect-claude-changes.sh) → automatic
• Manual capture (/forge capture) → user
• For manual web search: research and then use /forge capture with the findings

Phase 1: EVALUATE — Process inbox

Read all files in $DOTFORGE_DIR/practices/inbox/.

For each practice:

Acceptance criteria

1. Is it actionable? — Can be translated into a concrete change in dotforge
2. Is it new? — Does not duplicate something already in practices/active/
3. Is it generalizable? — Applies to >1 project (not project-specific)
4. Does it prevent a specific error? — If yes, annotate error_type and error description for tracking in metrics.yml

Classify

• Accept → move to practices/evaluating/, note proposed concrete change
• Reject → remove from inbox with a note explaining why
• Defer → leave in inbox with tag needs-more-info

Priority

1. Security (vulnerabilities, permissions)
2. Breaking changes (APIs that changed)
3. New features that simplify something existing
4. Patterns validated in >1 project
5. Minor optimizations

Show summary:

═══ INBOX EVALUATION ═══
{{N}} practices in inbox

✅ ACCEPT: {{title}} → {{proposed change}}
❌ REJECT: {{title}} → {{reason}}
⏸️ DEFER: {{title}} → {{what is missing}}

Proceed with accepted? (yes/no/select)

Phase 2: INCORPORATE — Apply changes to dotforge

For each accepted practice in evaluating/:

Determine impact

Apply

1. Show proposed diff to the user and ask for confirmation
2. Modify the corresponding dotforge files
3. If the practice warrants a new rule: generate a .md file in template/rules/ or stacks/*/rules/ with proper globs: (eager) or paths: + alwaysApply: false (lazy) frontmatter. Only create a rule if the practice is a repeatable constraint (not a one-time fix). Use existing rules as format reference.
4. Move practice from evaluating/ to active/ with incorporated_in: updated
5. Set frontmatter fields: effectiveness: monitoring (or informational if no error targeted — informational is excluded from the validation rate metric), error_type matching CLAUDE_ERRORS.md types
6. Register in $DOTFORGE_DIR/practices/metrics.yml:
   • error_targeted: description of the error this practice prevents (null if not error-targeted)
   • error_type: syntax | logic | integration | config | security | null
   • activated: today's date
   • status: monitoring (or informational — for general-knowledge practices, never validated)
   • recurrence_checks: 0
   • recurrence_target: 5
7. Update docs/changelog.md
8. Bump VERSION according to type

Phase 3: PROPAGATE — Suggest project updates

1. Read $DOTFORGE_DIR/registry/projects.local.yml
2. For each project, show what changed since its last sync:

═══ SUGGESTED PROPAGATION ═══

project-a (last sync: {{date or "never"}})
  → {{N}} rules updated

project-b (last sync: {{date or "never"}})
  → {{N}} rules updated

To propagate: run /forge sync in each project.

DO NOT propagate automatically. Inform only.

Phase 4: VERIFY — Recurrence check for active practices

For each entry in $DOTFORGE_DIR/practices/metrics.yml where status: monitoring:

1. Read CLAUDE_ERRORS.md from each project in registry where the practice is applied
2. Check if any error matching error_type + error_targeted description was logged AFTER the activated date
3. Increment recurrence_checks by 1, update last_checked to today
4. If error recurred: set recurred: true, status: failed
5. If recurrence_checks >= recurrence_target and recurred: false: set status: validated
6. Update effectiveness field in the practice's frontmatter file to match

Report:

═══ EFFECTIVENESS CHECK ═══
{{practice title}} — {{status}} ({{recurrence_checks}}/{{recurrence_target}} checks)
  {{if failed: "⚠ Error recurred — practice needs revision"}}
  {{if validated: "✅ No recurrence after {{N}} checks"}}
  {{if monitoring: "🔍 {{remaining}} checks remaining"}}

Skip practices with status: informational or status: validated. Informational practices are general-knowledge captures — they don't target an error, so recurrence is undefined and they never enter the validation rate.
