Command for Claude CodeGitHub Copilot

Written for Claude Code and GitHub Copilot: argument-hint in frontmatter, but also a Copilot chat mode or prompt. Also seen: agent in frontmatter.

This is coleam00/Archon's own configuration. It tells Claude Code and GitHub Copilot how to work on Archon 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 Archon configures →

About the project

Archon is a workflow engine for AI coding agents that turns development processes into YAML-defined sequences with phases, validation gates, and artifacts. Developers use it to run repeatable processes such as planning, implementation, testing, code review, and pull-request creation across projects. The catalogue entries provide commands, agents, skills, hooks, instructions, and settings for working with Archon.

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

review 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.

Code Review

Input: ${input:scope}

Your Mission

Perform a thorough code review:

  1. Understand what you're reviewing and its purpose
  2. Check the code against project patterns
  3. Run validation (type-check, lint, tests)
  4. Identify issues by severity
  5. Report findings

Golden Rule: Be constructive and actionable. Every issue should have a clear recommendation.


Phase 1: DETERMINE SCOPE

Parse Input

Input Type Example Action
PR number 123, #123 Fetch PR diff with gh pr diff 123
PR URL github.com/.../pull/123 Extract number, fetch PR diff
File path src/api/flags.ts Review single file
Folder path server/src/ Review all files in folder
Blank (none) Review unstaged git changes

Get Review Target

For PR:

gh pr view {NUMBER} --json number,title,author,files
gh pr diff {NUMBER}

For file/folder:

find {path} -name "*.ts" -o -name "*.tsx" | grep -v node_modules

For blank (unstaged changes):

git diff --name-only
git diff

Phase 2: CONTEXT

Read Project Rules

  • Read copilot-instructions.md for project conventions
  • Understand the patterns in the codebase

Understand Intent

  • For PRs: Read title and description
  • For files: Understand the file's purpose in the codebase
  • For changes: What was modified and why?

Phase 3: REVIEW

Review Each File

For each file in scope, check:

Category Check
Correctness Does the code work as intended?
Type Safety Are types explicit, no implicit any?
Patterns Does it follow existing codebase patterns?
Error Handling Are errors handled appropriately?
Tests Are there tests for this code?

Categorize Issues

Severity Criteria
Critical Security issues, data loss, crashes
High Type violations, missing error handling, logic errors
Medium Pattern inconsistencies, missing edge cases
Low Style suggestions, minor improvements

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.
