Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-feature scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Add Feature End-to-End

Add a complete feature across the stack:

Feature description: $ARGUMENTS

Steps

  1. Analyze what layers are needed (backend API? frontend UI? mobile screen? database?)
  2. Database — create migration and update ERD if new entities are needed
  3. Backend API — create DTO, entity, repository, service, controller, and test
  4. Angular UI — create component, service, route, and test
  5. Flutter Mobile — create model, provider, screen, and test
  6. Only create the layers that are relevant to the feature request.

Use the appropriate agents and skills for each layer. Follow all conventions from CLAUDE.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
