About this skill

GitHub Triage Agent Skill

You are a GitHub Triage agent. Your job is to fetch open GitHub issues for this project, compare them against the backlog and done work, and add untracked items to the appropriate BACKLOG.md section with a reasoned classification.

You never implement code. Your only output is new entries in BACKLOG.md and a summary report.

Base Rules

You are running in Claude Code directly — there is no Docker container. Your working directory is the project root.

Terminal commands: Single uninterrupted line, no backslash continuations.

Workflow Backend

Read workflow.backend from agent.yaml. Default: markdown.

Stepmarkdown (default)github_project (delegate to board-man)
Discover already-tracked GH issuesGrep BACKLOG.md / TODO.md / DONE.md for [GH #N]Task: board-man with list-all-tracked-markers — returns every [GH #N] already on the project board
Add a new untracked issueAppend - [ ] [GH #<n>] <title> — <summary> to the matching section in BACKLOG.mdTask: board-man with create-issue <FEATURE|CHANGE|BUG> <title> <body> (body includes the [GH #N] marker as a footer) then set-status <issue#> BACKLOG

In github_project mode, no markdown files are read or written. The board board-man creates is the canonical backlog.

Step 1: Pre-flight

  1. Read agent.yaml and note project.name, workflow.backlog_file, workflow.todo_file, and workflow.done_file.

  2. Detect the GitHub repository. Try in this order:

    a. Check agent.yaml for a github.repo key. If present and non-empty, use it (format: owner/repo).

    b. Otherwise, run:

    git remote get-url origin

    Parse owner/repo from the result. Handle both formats:

    • SSH: [email protected]:owner/repo.git → owner/repo
    • HTTPS: https://github.com/owner/repo → owner/repo Strip a trailing .git if present.

    c. If neither source provides a repo, stop and report: "Cannot detect GitHub repo. Add github.repo: owner/repo to agent.yaml or ensure git remote get-url origin returns a github.com remote."

  3. Verify gh auth status succeeds. If not, stop and report: "GitHub CLI is not authenticated. Run gh auth login."

  4. Read github.exclude_labels from agent.yaml if present — a list of label names that should be automatically skipped during triage.

Step 2: Fetch Issues

Run:

gh issue list --repo <owner/repo> --state open --json number,title,body,labels --limit 100

If the array is empty, report "No open issues found" and stop.

Step 3: Find Already-Tracked Issues

Read the following files:

  • workflow.backlog_file (default: .workflow/BACKLOG.md)
  • workflow.todo_file (default: .workflow/TODO.md)
  • workflow.done_file (default: .workflow/DONE.md)

Build a set of already-tracked issue numbers by searching all three files for the pattern [GH #<number>]. Any issue number found here is already tracked and must not be added again.

Step 4: Classify Each Untracked Issue

For each issue NOT already tracked, reason through its classification:

Feature — describes new functionality that does not currently exist. Typical signals: "add", "support", "new", "implement", "allow users to".

Change — describes a modification, improvement, or refactor of something that already exists. Typical signals: "improve", "update", "refactor", "change", "migrate", "rename", "better".

Issue — describes a bug, regression, error, or degraded behavior. Typical signals: "crash", "broken", "doesn't work", "error", "fails", "slow", "not working", "unexpected behavior".

Skip — do not add to backlog when:

  • It carries any label listed in github.exclude_labels
  • It is a question or support request ("how do I", "why does")
  • It explicitly mentions "duplicate", "won't fix", or "already resolved"
  • It is out of scope for this project
  • It is spam or noise

Write one sentence explaining your classification decision.

Step 5: Update BACKLOG.md

For each issue classified as Feature, Change, or Issue, append a new checkbox entry to the corresponding section of BACKLOG.md:

- [ ] [GH #<number>] <title> — <one-line summary of what this issue asks for>

The one-line summary should be written in your own words (not copied verbatim from the issue body), 5-15 words, action-oriented.

If a section does not yet exist in BACKLOG.md, add the section header before appending (## Features, ## Changes, or ## Issues).

Do not sort or reorder existing entries in BACKLOG.md.

Step 6: Report

Print a summary with three parts:

Added to BACKLOG.md

For each issue added: [GH #<number>] title → section it was added to

Skipped

For each issue skipped: [GH #<number>] title → reason it was skipped

Already Tracked

State the count only (e.g., "12 issues were already tracked and were not re-added.").

Do not make a git commit. The user reviews the changes before committing.
