At a glance

Takes a bug report for the triagebot-action GitHub Action through reproduction, root-cause diagnosis, an intended-behavior check and a fix attempt.

  • Works in 4 steps: Reproduce → Diagnose → Verify → …
  • Investigating a newly filed bug in the triagebot-action repository
  • SKILL.md covers General Rules, Input, Step 1: Reproduce and Step 2: Diagnose, plus 3 more sections
  • Calls gh

What it does

This is a repository-specific workflow for triagebot-action, a small TypeScript GitHub Action whose code lives in src/ and test/. You supply the issue title and body, or a GitHub issue number or URL that the agent fetches with gh issue view. Four stages follow, each handed to a subagent to keep context separate and each with its own instruction file: reproduce, diagnose, verify and fix.

The flow stops early when that makes sense. Skipped or non-reproducible issues, low-confidence diagnoses and a verdict of intended behavior all jump straight to the output, and if infrastructure trouble persists after two attempts the agent reports with the data it has. The result is a structured report that an orchestrator uses to post a comment and manage labels.

When your agent uses it

  • Investigating a newly filed bug in the triagebot-action repository
  • Checking whether a reported behavior is intended before changing any code
  • Producing a structured triage report that automation can turn into an issue comment

Example prompts

  • “Triage the issue titled 'Labels not removed after reclassification' and try to reproduce it.”
  • “Reproduce and diagnose the bug in this issue body, then tell me how confident you are.”
  • “Check whether the routing behavior in this report is intended, and fix it if it is a real bug.”

Requirements

  • GitHub CLI (gh) to fetch issue details when only an issue reference is given

Workflow steps

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

  1. Reproduce
  2. Diagnose
  3. Verify
  4. Fix

What it can do on your machine

Read from SKILL.md and the folder at commit 28e7410. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    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

Triagebot Action Bug Triage loads about 639 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 355 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~639

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 355 words (~639 tokens).

“Triage a bug report end-to-end: reproduce the bug, diagnose the root cause, verify whether the behavior is intentional, and attempt a fix.”
