compliance-trestle-skills: Instructions file for Gemini CLI

GEMINI.md

compliance-trestle-skills GEMINI.md is an instructions file for Gemini CLI from oscal-compass-lab/compliance-trestle-skills. It costs 525 tokens per session, scanned A, original, Apache-2.0.

Instructions for an engineering toolkit focused on OSCAL, a standard format for describing security controls and compliance information, and Compliance Trestle, its supporting toolset. It also defines rules for using the Gemini command-line tool and preserving document evidence.

In plain words
What is it for?
Use it when working on OSCAL documents, compliance assessments, plans of action, document conversion, validation, or the repository's portable skills.
Why use it?
It gives coding agents the project rules needed to edit compliance documents safely and consistently.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md. Also seen: mentions AGENTS.md; mentions Gemini CLI.

This is oscal-compass-lab/compliance-trestle-skills's own configuration. It tells Gemini CLI how to work on compliance-trestle-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything compliance-trestle-skills configures →

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

compliance-trestle-skills GEMINI.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 11d 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.

Gemini CLI Instructions

This repository is an agent-portable Compliance Trestle and OSCAL engineering toolkit. Use it from Gemini CLI. Read this file and AGENTS.md before you make changes.

Write project documentation in ASD-STE100 Simplified Technical English.

Repository purpose

The toolkit helps coding agents do OSCAL document engineering, Compliance Trestle authoring, assessment workflows, POA&M workflows, and validation.

Key paths

  • AGENTS.md : full generic coding-agent instructions.
  • agent-skills/ : portable skills that Gemini can read as task playbooks.
  • commands/ : primary Compliance Trestle command docs.
  • skills/ : root Compliance Trestle skills.
  • plugins/document-transform/ : OSCAL document workbench scripts, command docs, templates, and skill.
  • docs/AGENT-COMPATIBILITY.md : harness compatibility matrix.
  • docs/PORTABLE-SKILLS.md : portable skill-pack contract.

Required guardrails

  • Use Python 3.10-3.12 with Compliance Trestle. Python 3.14+ prints an expected Pydantic V1 warning on every trestle command.
  • Preserve source traceability for legacy document conversion.
  • Do not treat missing system details as facts. Mark them needs_review.
  • Do not copy licensed framework text.
  • Validate generated OSCAL structurally before you claim success.
  • Keep sensitive customer evidence out of the repository.

Legacy document to OSCAL quick path

For PDF, DOCX, or Markdown SSP conversion, do these steps:

  1. Read agent-skills/oscal-document-engineering/SKILL.md.
  2. Make a workspace outside committed source unless you use a synthetic example.
  3. Extract text.
  4. Keep page and section references.
  5. Build or update a Compliance Trestle workspace.
  6. Map source content into OSCAL SSP fields with source traceability.
  7. Run Trestle and OSCAL validation if installed.
  8. Make summary, validation, and unmapped-content reports.

Validation commands

npm run test:agent-skills
npm run test:agent-adapters
npm run test:cursor-support
npm run test:oscal-document-workbench
npm run test:draft-ssp
npm run test:trestle-integration
npm run test:oscal-review-workflow

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.
