open-agent-kit: Skill for Claude Code

.agents/skills/project-governance/SKILL.md

project-governance is a skill for Claude Code from goondocks-co/open-agent-kit. It costs 59 tokens per session (1,527 once invoked), scanned A, original, MIT.

A set of tools for defining project rules and keeping coding-agent instructions consistent. It supports constitutions, which are shared project standards, as well as RFCs and ADRs for recording technical decisions.

In plain words
What is it for?
Creating project standards, adding agent guidance, finding existing instruction files, synchronizing rules across them, and documenting technical decisions.
Why use it?
It gives people and coding agents a common source of project expectations instead of leaving rules scattered across files. It also helps discover and update the instruction files already used by a project.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is goondocks-co/open-agent-kit's own configuration. It tells Claude Code how to work on open-agent-kit 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 open-agent-kit 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

project-governance 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Governance

Create, modify, and maintain project constitutions and agent instruction files that guide AI agents. Also supports RFC/ADR documents for formalizing technical decisions.

Quick Start

Create a constitution

# Analyze the project, then create oak/constitution.md
# See references/constitution-guide.md for the full process

Create agent instruction files

oak-dev rules detect-existing      # Discover all configured agent instruction files
oak-dev rules sync-agents          # Sync constitution references to all agent files

Commands Reference

Command Purpose
oak-dev rules detect-existing Discover all configured agent instruction files
oak-dev rules detect-existing --json Machine-readable output of agent files
oak-dev rules sync-agents Sync constitution references to all agent instruction files
oak-dev rules sync-agents --dry-run Preview what files will be checked/updated

When to Use

  • Creating a new constitution for a project that doesn't have one
  • Creating agent instruction files for a new project (use oak-dev rules detect-existing to discover correct file names)
  • Adding rules when you identify patterns that should be standardized
  • Syncing agent files after constitution changes
  • Learning context engineering theory behind effective rule writing -- see /context-engineering for the altitude concept, canonical examples, and structured context patterns

Constitution Structure

A good constitution is explicit, enforceable, and anchored:

Quality Good Bad
Specificity "All API endpoints MUST validate input using Pydantic models" "Use best practices"
Anchors "Copy src/features/auth/service.py for new services" "Follow good patterns"
Non-goals "This tool is NOT a CI/CD orchestrator" (no boundaries)
Gates "make check must pass for all changes" "Add tests if needed"

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.

project-governance is a skill published in the GitHub repository goondocks-co/open-agent-kit (10 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 1,527 once invoked, about $0.0003 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 2026-08-31.
