What it does

Closing Obsolete Issues is an agent skill from flutter/devtools. Find and close obsolete, stale, or not reproducible issues in the flutter/devtools repository.

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/rationale_templates.md`, `scripts/fetch_issue_details.sh` and `scripts/search_prs.sh`).

It sits in Mobile, covering Cross-platform mobile apps. It works with Flutter. The repository describes itself as: Developer tools for Flutter & Dart. The licence is BSD-3-Clause.

When your agent uses it

  • Tasks that involve Cross-platform mobile apps

Example prompts

  • “/closing-obsolete-issues”

Requirements

  • A Bash shell

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify Target Issues
  2. Investigate Status
  3. Draft and Review Closing Comments (CRITICAL MANDATE)
  4. Iterate on Skill Knowledge (Learning Loop)
  5. Execute and Summarize

What it can do on your machine

Read from SKILL.md and the folder at commit e25ba13. 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

    Ships 4 files in scripts/ (Shell and Dart), which the agent can run.

    Shell commands in SKILL.md call:

    • gh
    • dart

    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

Closing Obsolete Issues loads about 949 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 30 tokens; SKILL.md has 534 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~949
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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); the scripts in this folder are not scanned.

Closing Obsolete Issues

Use this skill to find old, outdated issues in the flutter/devtools repository that can be closed because they have been fixed, are stale, obsolete, or not reproducible.

Instructions

  1. Identify Target Issues:

    • Use the GitHub CLI (gh) to search for the oldest open issues.
    • Use any label that the user gives you, or none if the user does not specify any issue labels.
    • Sort by creation date (created-asc) or last update (updated-asc) to find the most likely candidates for being outdated.
    • Fetch at least 20-30 candidates.
    • Example command (with label): gh issue list --repo flutter/devtools --search "label:bug is:open sort:created-asc" --limit 30 | cat
    • Example command (without label): gh issue list --repo flutter/devtools --search "is:open sort:created-asc" --limit 30 | cat

  2. Investigate Status:

    • For each candidate, analyze its description and comments.
    • Pro Tip: Use the bundled script dart scripts/fetch_issues.dart <numbers...> or dart scripts/fetch_issues.dart --page <number> to get a comprehensive view of issues and their comments.
    • Compare the issue's request or reported bug with the current state of the codebase.
    • Refer to references/rationale_templates.md for a library of common reasons issues become outdated in DevTools.
    • Safety Rule: Do not assume a bug is fixed or obsolete just because the screen has been updated or the file modified. Verify if the specific bug behavior is still possible. Valid bugs or feature requests should not be closed as stale just because they are old or have no activity. Inactivity alone does not invalidate a feature request or bug report.

  3. Draft and Review Closing Comments (CRITICAL MANDATE):

    • For issues identified as candidates for closing, draft a detailed comment for each explaining why it can be closed.
    • Style Constraint: DO NOT use em dashes (—) in the comments. Use hyphens (-) or colons (:) instead.
    • Template: Consult references/rationale_templates.md for wording inspiration.
    • Each comment MUST end with: "If there is more work to do here, please let us know by filing a new issue with up to date information. Thanks!"
    • User Approval Required: You MUST present the identified issues (including URLs to the issues for easy navigation) and their drafted comments to the user and obtain explicit approval BEFORE running any command that closes an issue.

  4. Iterate on Skill Knowledge (Learning Loop):

    • If you discover a new, distinct category of closing rationale that is not covered in references/rationale_templates.md, update the reference file to include it.

  5. Execute and Summarize:

    • Once approved, use gh issue close with the -c flag to post the comment and close the issue.
    • Provide the user with a clean bulleted list of links to each closing comment.

Tips

  • Use available file and content search tools (such as grep, ripgrep, or environment-specific search tools) to check the current codebase for references to the issue or relevant code.
  • Look for related PRs that might have fixed the issue but didn't close it automatically.
  • Pro Tip: Use the bundled script dart scripts/search_prs.dart <query> to search for PRs in the repository.
  • For issues reporting specific versions, check the current DevTools version in packages/devtools_app/pubspec.yaml to determine if the reported version is very old. If the reported version is 1 or more major versions behind or 12 or more minor versions behind the current version, this issue is a good candidate for being obsolete.
