p3-security

p3-security is a command for coding agents from jonase47/ccpr. It costs 0 tokens per session (983 once invoked), scanned A, original, MIT.

Creates the complete security architecture: threat model, auth concept, data security, API security and developer checklist. Each area is its own sub-skill.

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-security 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-security – Security Architecture, Threat Model & Auth Concept

Creates the complete security architecture: threat model, auth concept, data security, API security and developer checklist. Each area is its own sub-skill.

Argument: $ARGUMENTS = [Focus, e.g. "Auth", "API Security", "Data Encryption"]

If provided: Passed through to the sub-skills. If not provided: All sub-skills run sequentially.

Flow

0. Ensure Sub-Index Exists

Make sure docs/architecture/SECURITY.md exists as a sub-index with the standard header (Status / Last Updated / Key Decisions / Open Risks / Detail Files / Gate Notes — see ~/.claude/docs/PROJECT_PHASES.md). If missing, create it with empty placeholders. The five p3-sec-* sub-skills below each refresh their own row in this sub-index's Detail Files table.

1. STRIDE Threat Model

/p3-sec-threats $ARGUMENTS – Analyzes the system according to the STRIDE model.

2. Auth & Authorization Concept

/p3-sec-auth $ARGUMENTS – Defines auth method, roles and session management.

3. Data Security

/p3-sec-data $ARGUMENTS – Encryption (transit/rest), secrets management, backups.

4. API Security

/p3-sec-api $ARGUMENTS – Input validation, rate limiting, CORS, security headers.

5. Developer Checklist

/p3-sec-checklist – Concrete security checklist for phase 5.

6. Roll Up Sub-Index to Phase Index

After all p3-sec-* sub-skills have run, summarise the security sub-index into the phase index docs/architecture/ARCHITECTURE.md:

  • Add an entry in the phase-index Detail Files table for [SECURITY.md](SECURITY.md) (the sub-index itself), status complete once all five sub-skill rows in SECURITY.md are complete.
  • Lift the headline security decisions (auth method, encryption strategy, top critical threat) into the phase-index Key Decisions.
  • Lift any unresolved Critical/High threats from THREATS.md into the phase-index Open Risks.

7. Final HANDOVER Update (Orchestrator-owned)

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-security 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 983 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.
