api-handlers

api-handlers is a cursor rule for Cursor from geniro-io/geniro-claude-harness. It costs 0 tokens per session (60 once invoked), scanned A, original, Apache-2.0.

Rules for HTTP handlers, the code that receives web requests and returns responses. They require each handler to return a status and response body instead of writing directly to the response stream.

In plain words
What is it for?
Use them when implementing or reviewing handlers, especially those involving feature flags or database-backed decisions.
Why use it?
They keep request handling consistent and prevent handlers from bypassing the application's flag and data-access conventions.

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

api-handlers 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 8d ago.

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

  • Every handler returns (status int, body any); never writes to the response writer directly.
  • A handler that needs a flag calls the evaluator; it never reads Postgres.
Changes

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.
