Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00276 | $0.00276 |
| Opus 5 | $0.00138 | $0.00138 |
| Sonnet 5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
gangsta 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 5d 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
Contributing to Gangsta
What This Is
Gangsta is an AI agentic skills framework for spec-driven development. Skills are behavior-shaping code, not documentation. They must be tested rigorously.
What Will NOT Be Accepted
- Third-party dependencies (this is a zero-dependency package)
- Changes that weaken Omerta governance rules
- Skills without adversarial pressure testing
- Bulk PRs with unrelated changes bundled together
- "Improvements" that add complexity without clear value
- Narrative storytelling in skill content (skills are instructions, not blog posts)
Skill Changes
Every skill change requires:
- Baseline testing: Run a pressure scenario WITHOUT the change, document behavior
- Change testing: Run the same scenario WITH the change, document improvement
- Include both results in your PR
The Laws Apply to Contributors Too
- Omerta Law 3 (Rule of Truth): Every claim in a PR must be verifiable
- Omerta Law 5 (Spec is Law): Changes must align with the framework design spec
The Constitutional Floor
Active Negative Constraints in docs/gangsta/constitution.md are binding on contributors. Adding or modifying a Negative Constraint requires Don approval through a Heist; do not edit docs/gangsta/constitution.md directly in a PR without an associated Heist.
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.

gangsta AGENTS.md is an instructions file published in the GitHub repository kucherenko/gangsta (81 stars, last pushed 22d ago), licensed MIT. It adds 276 tokens to every session, about $0.0014 per session on Opus 5. 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 2026-08-30.
