gitto

A search tool for finding bug-related code patterns, issues, and example fixes in public GitHub repositories.

In plain words
What is it for?
Use it to investigate a bug, search for matching error messages or framework patterns, find related GitHub issues, and compare candidate fixes in public code.
Why use it?
It gives developers prior examples from other projects when a bug is unfamiliar or the current codebase offers no clear solution.

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

gitto 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 2d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Turn a bug description into targeted GitHub code and issue searches, then summarize patterns and candidate fixes.

When to Use

  • Investigating a bug and want to see how others solved similar issues
  • Looking for code patterns or examples from public repositories
  • The user provides a problem statement but no specific repo to inspect
  • Redux/RTK issue triage - finding related issues or prior art

Inputs

  • Bug description (required)
  • Optional: language, framework, error strings, org/repo constraints, result limit

Process

  1. Extract key phrases, error strings, and likely library/framework terms from the bug description
  2. Build 2-4 query variants with GitHub code search qualifiers
  3. Run searches using the gitto script (uses gh CLI if authenticated, falls back to API)
  4. Rank results by relevance and return URLs with snippets
  5. Provide analysis: summarize patterns, likely root causes, and 2-3 candidate fixes

Command

bun ~/.config/opencode/skill/gitto/gitto-search.ts \
  --query "<bug description or keywords>" \
  --language "typescript" \
  --limit 15 \
  --issues true

Options

  • --query (required): Bug description or search keywords
  • --language: Filter by language (e.g., "typescript", "javascript")
  • --repo: Specific repo (e.g., "reduxjs/redux-toolkit")
  • --org: Organization filter
  • --limit: Max results (default: 20)
  • --issues: Include issue search (default: true)

Output Format

  • Code results: Repo, file path, URL, snippet
  • Issue results: Title, URL, body snippet
  • Use results to provide analysis of patterns and candidate fixes

Example Usage

For Redux middleware issues:

bun ~/.config/opencode/skill/gitto/gitto-search.ts \
  --query "middleware dispatch undefined action" \
  --org "reduxjs" \
  --language "typescript" \
  --limit 10

For React hooks errors:

bun ~/.config/opencode/skill/gitto/gitto-search.ts \
  --query "useEffect cleanup memory leak" \
  --language "typescript" \
  --issues true

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.

gitto is a skill published in the GitHub repository markerikson/opencode-config-example (44 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 605 once invoked, about $0.0002 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 2026-08-30.
