taken?

taken? answers one question before you volunteer for a GitHub issue: is it already taken?

The catch it was built for: GitHub shows "linked a pull request" events in the issue timeline, but never in the comments. You can read every comment on an issue and still miss that someone already opened a PR for it. taken? checks the timeline, scans comments for people claiming the work, looks at assignees, reads CONTRIBUTING.md for AI contribution policies, and checks whether the repo is still active. Then it gives a verdict, GO, TAKEN, or CAUTION, with the evidence cited.

Requirements

• Python 3.10 or newer
• The GitHub CLI (gh), authenticated

taken? only makes read-only API calls through your own gh login. It never sees or stores tokens, and it never writes anything to GitHub.

Install as a tool

uv tool install taken-gh
taken owner/repo#123

Or with pipx:

pipx install taken-gh
taken owner/repo#123

Usage

uv run taken owner/repo#123

A full issue URL works too:

uv run taken https://github.com/owner/repo/issues/123

Useful flags:

• --json: print the full findings as JSON instead of the human summary
• --me LOGIN: ignore your own comments when scanning for claimants
• --file PATH: read targets from a file, one per line
• --limit N: scan mode checks at most N open issues per repo (default: 20)
• --label LABEL: scan mode only considers open issues carrying this label
• --no-cache: bypass the API response cache
• --version, --help

Exit codes: 0 means GO, 1 means TAKEN, 2 means CAUTION, 3 means something broke (bad target, no gh, API error). With several targets the exit code is 0 when every target produced a verdict and 3 when any target failed.

Batch mode and repo scans

Give taken several targets and it prints one verdict line per target:

taken owner/repo#123 owner/repo#124 --me mylogin
TAKEN   owner/repo#123  assigned to: dk5488
GO      owner/repo#124  no linked PRs, no assignees, no claimants, repo is active

A bare owner/repo scans the repo automatically: its open issues (most recently updated first, PRs excluded) are each checked:

taken django/django --label "good first issue" --limit 10

API responses are cached for one hour in ~/.cache/taken (override with TAKEN_CACHE_DIR), so repeated scans stay cheap. --no-cache skips the cache.

Discover mode

taken --discover finds contribution candidates across GitHub. It piggybacks on GitHub's issue search API (the same source the web aggregators use) for raw candidates, then runs taken's full verification on each one and ranks the survivors. Only GO verdicts make the list.

taken --discover --language python --min-stars 50 --limit 10
  6  octocat/hello-world#42  maintainer replied; updated 1d ago; repo pushed 0d ago
  4  octocat/other-repo#7    updated 3d ago; repo pushed 2d ago

Candidates are scored on the signal no aggregator filters on: maintainer responsiveness. A non-author, non-bot comment scores +3; an issue updated in the last 7 days scores +2; a repo pushed in the last 7 days scores +1. Each line explains its own score. --label restricts the search to one label instead of the default set (good first issue, good-first-issue, beginner friendly, help wanted).

Candidates are verified in parallel (8 workers by default; --jobs N tunes it). A progress bar on stderr shows live feedback during the run; --no-progress hides it. The bar never touches stdout, so --json stays script-friendly.

JSON output

taken --json owner/repo#123 prints an object with three keys:

• verdict: one of GO, TAKEN, CAUTION
• reasons: list of human-readable strings explaining the verdict
• findings: the raw check results:
  • target: e.g. owner/repo#123
  • issue: number, state, title, labels, assignees, comment_count, author, url, created_at
  • linked_prs: list of number, title, state, merged, author, url
  • claimants: list of author, date, pattern, snippet, url
  • ai_policy: verdict (ban, disclosure-required, or none-found), snippet, source
  • repo_health: pushed_at, pushed_recently, recent_merges, stars

Examples

An issue with a PR already fixing it:

$ uv run taken Exodus-Privacy/exodus#300
taken? Exodus-Privacy/exodus#300
verdict: TAKEN
  ...
  why:
    - open PR #700 already covers this: https://github.com/Exodus-Privacy/exodus/pull/700

An issue someone is already assigned to:

$ uv run taken chahe-dridi/vscode-agent-bell#200
taken? chahe-dridi/vscode-agent-bell#200
verdict: TAKEN
  ...
  why:
    - assigned to: dk5488

A clean issue, with your own volunteering comment filtered out:

$ uv run taken snowflakedb/snowflake-cli#3145 --me RogueAlg0
taken? snowflakedb/snowflake-cli#3145
verdict: GO
  ...
  why:
    - no linked PRs, no assignees, no claimants, repo is active

How the verdict works

TAKEN wins over CAUTION, which wins over GO.

• TAKEN: the issue is closed, an open PR links to it, or someone is assigned.
• CAUTION: a comment says someone wants it (soft claim, they may have moved on), a linked PR was merged but the issue is still open, the repo has an AI policy to respect, or the repo looks inactive.
• GO: none of the above.

The claimant scan is a heuristic over comment text, not proof. The verdict always prints its evidence so you can judge for yourself.
