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

p3-sec-api 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.

/p3-sec-api – API Security Requirements

Defines input validation, rate limiting, CORS and security headers.

Argument: $ARGUMENTS = [Focus, e.g. "CORS", "Rate Limiting", "Headers"]

If provided: Deep-dive the named area. If not provided: Create complete API security requirements.

Prerequisites

  • ARCHITECTURE.md exists
  • API endpoints known (from DATA_MODEL.md or API_SPEC.md)

Agent

  • Type: security-master
  • Model: sonnet

Context (Orchestrator prepares)

Orchestrator reads beforehand and delivers inline:

  • From ARCHITECTURE.md: API components and data flows
  • From DATA_MODEL.md: API endpoints (if available)
  • From TECH_STACK.md: Backend framework

Prompt Template

Goal: Define API security requirements.

Context: [inline from ARCHITECTURE.md, DATA_MODEL.md]

Output Format:

  1. Input validation: strategy (whitelist/blacklist), sanitization
  2. Rate limiting: Table | Endpoint Type | Limit | Time Window |
  3. CORS: allowed origins, methods, headers
  4. Security headers: Table | Header | Value | Purpose |

Constraints:

  • ONLY API security, NO auth concept, NO data encryption
  • Max. 6 rate limit rules
  • Max. 8 security headers
  • If no API present: explicitly justify and keep section minimal

Orchestrator Checkpoint

  • OWASP Top 10 API risks considered?
  • Security headers complete (CSP, X-Frame-Options, etc.)?

Write Detail File

Write the result to docs/architecture/API_SECURITY.md (overwrite if it exists). Start with this YAML frontmatter:

---
phase: P3
subskill: sec-api
status: active
last_updated: <DD.MM.YYYY>
---

Body sections: ## Input Validation, ## Rate Limiting, ## CORS, ## Security Headers.

Update Sub-Index

Update docs/architecture/SECURITY.md:

  • Set **Last Updated:** <DD.MM.YYYY>.
  • In its Detail Files table: ensure a row for [API_SECURITY.md](API_SECURITY.md) with status complete.
  • Note any OWASP Top-10-API risk that is NOT yet mitigated under Open Risks of the sub-index.
  • Do not edit ARCHITECTURE.md directly.

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.

p3-sec-api is a command published in the GitHub repository jonase47/ccpr (1 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 865 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
