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

pm-skills-arsenal AGENTS.md 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 12d 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.

Name: PM Skills Arsenal Author: Parth Sangani Description: 12 PM skills encoding domain expertise as loadable context for AI agents. Each skill is 1,000-1,300 lines of methodology, frameworks, and failure modes — not prompt templates. Benchmark (self-administered): 98/105 on a self-authored 7-dimension rubric, scored by the same author who wrote the skills. Methodology + 15 raw outputs at benchmark/ for independent re-scoring. Read this score with that lens. Compliance: All 12 skills pass validate_skills.py discoverability audit (capability_summary + input_schema + output_schema + example_invocation + description all present). Latest audit: 2026-04-23.

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.
