What it does
Closing Obsolete Issues is an agent skill from dart-lang/ai. Find and close obsolete, stale, or not reproducible issues in the dart-lang/ai repository.
Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rationale_templates.md`).
The repository describes itself as: A general repository for AI / GenAI packages and explorations. The licence is BSD-3-Clause.
Example prompts
- “/closing-obsolete-issues”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify Target Issues
- Investigate Status
- Draft and Review Closing Comments (CRITICAL MANDATE)
- Iterate on Skill Knowledge (Learning Loop)
- Execute and Summarize
What it can do on your machine
Read from SKILL.md and the folder at commit 60a4b18. 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
Closing Obsolete Issues loads about 794 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 448 words of instructions outside code blocks.
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.

Closing Obsolete Issues
Use this skill to find old, outdated issues in the dart-lang/ai repository that can be closed because they have been fixed, are stale, obsolete, or not reproducible.
Instructions
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 10-20 candidates.
- Example command (with label):
gh issue list --repo dart-lang/ai --search "label:bug is:open sort:created-asc" --limit 20 | cat - Example command (without label):
gh issue list --repo dart-lang/ai --search "is:open sort:created-asc" --limit 20 | cat
- Use the GitHub CLI (
Investigate Status:
- For each candidate, analyze its description and comments.
- Use
gh issue view <number> --repo dart-lang/aito get details. - Compare the issue's request or reported bug with the current state of the codebase.
- Refer to
references/rationale_templates.mdfor a library of common reasons issues become outdated. - Safety Rule: Do not assume a bug is fixed or obsolete just because the code has been updated. 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.
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.mdfor wording inspiration. - Each comment MUST end with: "If there is more work to do here, please let us know by commenting on this issue or filing a new one 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.
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.
- If you discover a new, distinct category of closing rationale that is not covered in
Execute and Summarize:
- Once approved, use
gh issue closewith the-cflag to post the comment and close the issue. - Provide the user with a clean bulleted list of links to each closing comment.
- Once approved, use
Show full SKILL.md (40 more words)Show less
Tips
- Use available file and content search tools (such as
grep,ripgrep) 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.
