* feat: add Rails 8 application CLAUDE.md example
Adds examples/rails-app-CLAUDE.md as a reference template for Rails 8 applications.
- Add examples/rails-app-CLAUDE.md: full-stack Rails 8 template covering Hotwire (Turbo + Stimulus), ViewComponent, the Solid stack (SolidQueue, SolidCache, SolidCable), service objects, query objects, and Pundit authorization
- Aligns with existing rules/ruby/ conventions (Rails Way first, SolidQueue for greenfield, Hotwire-preferred, Rails 8 generated authentication)
- Includes five Key Patterns code blocks: service object, skinny controller, query object, background job, RSpec test
new file: examples/rails-app-CLAUDE.md
* fix(examples): correct Rails 8 CLAUDE.md examples for auth, transactions, and terminology
- Remove Django `select_related` terminology in favor of direct Rails methods
- Replace `authenticate_user!` (Devise-only) with `require_authentication` (Rails 8 generator default), with inline comment noting Devise as the alternative
- Move `send_notifications` outside the transaction block in the service object example so it only runs after a confirmed commit; safe with both SolidQueue and Sidekiq
- Remove `puts` from the N+1 BAD/GOOD example to align with the Ruby Conventions rule that bans `puts` in committed code
* fix(examples): improve idempotency, notification handling, and job argument guidance
- Wrap send_notifications in its own rescue block so notification failures are logged but do not raise out of the service object, preserving the Result-based error handling pattern
- Update the background job example to show an idempotency_key passed to the external API call, so the example is retry-safe by default rather than relying on a comment to flag the limitation
- Add a Background Jobs rule about pairing local idempotency checks with API-level idempotency tokens and considering with_lock for high-concurrency scenarios
- Soften the absolute "never records" claim for job arguments to explain the real reason (ActiveJob::DeserializationError when records are deleted between enqueue and execute)
* fix(examples): use exported_at.present? to match the column the example writes
The previous `exported?` check assumed a predicate method on the model that this example does not define. Using `exported_at.present?` keeps the guard consistent with the column the next line writes to in `update!(exported_at: Time.current)`.
Add compact prompt-defense baselines to active ECC prompt surfaces and copied CLAUDE examples. AgentShield prompt-defense findings are now zero; local tests passed 2366/2366.
Salvages the useful statusline/context monitor work from stale PR #1504 while preserving the current continuous-learning hook runner wiring.
Adds the metrics bridge, context monitor, statusline script, shared cost/session bridge utilities, and tests. Fixes the reviewed false loop-detection hash collision for non-file tools, avoids default-session cost inflation, sanitizes statusline task lookup, and records hook payload session IDs in cost-tracker.
Implements Anthropic's March 2026 harness design pattern — a multi-agent
architecture that separates generation from evaluation, creating an
adversarial feedback loop that produces production-quality applications.
Components:
- 3 agent definitions (planner, generator, evaluator)
- 1 skill with full documentation (skills/gan-style-harness/)
- 2 commands (gan-build for full apps, gan-design for frontend)
- 1 shell orchestrator (scripts/gan-harness.sh)
- Examples and configuration reference

- Add hooks/README.md: comprehensive hook documentation with input schema,
customization guide, 4 ready-to-use hook recipes, and cross-platform notes
- Expand planner agent with full worked example (Stripe subscriptions plan)
and sizing/phasing guidance (119 → 212 lines)
- Add Django REST API example config (DRF + Celery + pytest + Factory Boy)
- Update README directory tree with new files
