What is forgejo-claude-code-action CLAUDE.md?

A contributor guide for a GitHub Action that lets Claude respond to GitHub issues and pull requests. It describes the project’s Bun-based development commands, event handling, GitHub data collection, and supported AI providers.

Developing and testing the action, handling /claude triggers, gathering GitHub discussions, creating prompts, and configuring integrations with Anthropic, AWS Bedrock, Google Vertex, and GitHub MCP.

It gives coding agents the project-specific rules and commands needed to change, format, and test the action consistently.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00497	$0.00497
Opus 5.5	$0.00199	$0.00199
Sonnet 5.5	$0.00099	$0.00099
Haiku 4.5	$0.00050	$0.00050

Measured 2mo ago against content hash 14c0e9e1f2a3, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

forgejo-claude-code-action CLAUDE.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 2mo 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.

Architecture Overview

This is a GitHub Action that enables Claude to interact with GitHub PRs and issues. The action:

Trigger Detection: Uses check-trigger.ts to determine if Claude should respond based on comment/issue content
Context Gathering: Fetches GitHub data (PRs, issues, comments) via github-data-fetcher.ts and formats it using github-data-formatter.ts
AI Integration: Supports multiple Claude providers (Anthropic API, AWS Bedrock, Google Vertex AI)
Prompt Creation: Generates context-rich prompts using create-prompt.ts
MCP Server Integration: Installs and configures GitHub MCP server for extended functionality

Key Components

Trigger System: Responds to /claude comments or issue assignments
Authentication: OIDC-based token exchange for secure GitHub interactions
Cloud Integration: Supports direct Anthropic API, AWS Bedrock, and Google Vertex AI
GitHub Operations: Creates branches, posts comments, and manages PRs/issues

Important Notes

Actions are triggered by @claude comments or issue assignment unless a different trigger_phrase is specified
The action creates branches for issues and pushes to PR branches directly
All actions create OIDC tokens for secure authentication
Progress is tracked through dynamic comment updates with checkboxes

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.
