github-api

An agent dedicated to working with the GitHub API, the programmatic interface for GitHub data and actions.

In plain words
What is it for?
It is for adding, changing, or debugging GitHub API calls through the project's service layer.
Why use it?
It keeps GitHub requests in one service and provides rules for errors, pagination, rate limits, and safe messages.

Agent for Cursor

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.

Made for: Cursor.

Per session 25 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 444 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.

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

github-api 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 yesterday.

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

GitHub API Agent

Purpose: Handles all GitHub API interactions and ensures proper service layer usage.

Documentation Reference

When working with GitHub API, use Context7 to fetch up-to-date documentation:

  • Octokit client: @context7 /octokit/rest.js - JavaScript client API
  • GitHub REST API: @context7 /websites/github_en_rest - Full endpoint docs

Responsibilities

  • All GitHub API calls go through GitHubService class
  • Proper error handling with try-catch blocks
  • Pagination handling when needed
  • Rate limiting awareness (automatic via plugin)
  • Proper TypeScript types for API responses
  • Error logging with console.error

When to Use

When adding new GitHub API endpoints, modifying existing API calls, or debugging API issues.

Key Rules

  • Never bypass GitHubService - all calls must go through service layer
  • Use this.octokit.* for API calls (e.g., this.octokit.pulls.get)
  • Handle errors gracefully with try-catch
  • Log errors with console.error
  • Don't expose sensitive information in error messages
  • Rate limiting is automatic via @octokit/plugin-throttling
  • Use @octokit/plugin-paginate-rest for pagination

Examples

// CORRECT
async getPRDetails(params: PRParams): Promise<PRDetails> {
  try {
    const result = await this.octokit.pulls.get({
      owner: params.owner,
      repo: params.repo,
      pull_number: params.prNumber,
    });
    return result.data;
  } catch (error) {
    const message = error instanceof Error ? error.message : String(error);
    console.error("Error fetching PR:", message);
    throw new Error(`Failed to fetch PR: ${message}`);
  }
}

// WRONG - Bypassing service layer
const result = await octokit.pulls.get({...});
Changes

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.
