Investigating GitHub Issues

What it does

When your agent uses it

• A GitHub issue URL is provided
• Asked to analyze
• Triage an issue

Example prompts

• “/investigating-github-issues”

Requirements

• Pre-approved tools (allowed-tools): Bash(gh issue view *), Bash(gh issue list *), Bash(gh pr list *), Bash(gh pr view *), Bash(gh pr checks *), Bash(gh pr diff *), Bash(gh release list *), Bash(git log *), Bash(git tag -l*), Bash(git show *), Read, Glob, Grep

Workflow steps

7 steps, taken from the step headings in SKILL.md.

1. 1Fetch Issue Details
2. 2Assess Version Status
3. 3Search for Similar Issues and Existing PRs
4. 4Attempt Code-Level Reproduction
5. 5Investigate Relevant Code
6. 6Classify and Analyze
7. 7Produce the Investigation Report

What it can do on your machine

Read from SKILL.md and the folder at commit 07cdf94. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(gh issue view *)
  • Bash(gh issue list *)
  • Bash(gh pr list *)
  • Bash(gh pr view *)
  • Bash(gh pr checks *)
  • Bash(gh pr diff *)
  • Bash(gh release list *)
  • Bash(git log *)
  • Bash(git tag -l*)
  • Bash(git show *)

  …and 3 more on the same allowed-tools line.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • gh
  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • github.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Investigating GitHub Issues loads about 1.5k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 694 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~101

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Read-only investigation and analysis of GitHub issues for Shopify/shopify-app-js. Fetches issue details via gh CLI, searches for duplicates, examines the codebase for relevant context, applies version-based maintenance policy classification, and produces a structured investigation report. Use when a GitHub issue URL is provided or when asked to analyze or triage an issue.
