## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

First indexed and scored.

## MCP tools (9)

### `contribos_policy` (~81 tokens)

What a GitHub repository expects from outside contributors: AI policy, vouch/trust gates, claim-first norms, tests, changelog, sign-off, activity. Every finding cites file:line. Call this before starting work on any repo.

Input parameters:

- `json` (boolean): return machine-readable rules instead of markdown
- `repo` (string, required): owner/name

### `contribos_brief` (~86 tokens)

Evidence-backed contribution brief for an issue: files to read with reasons, similar past PRs, related tests, look-alike files to avoid, house rules and likely review questions.

Input parameters:

- `issue_url` (string): GitHub issue URL (needs API access)
- `repo` (string): owner/name, when giving title instead of issue_url
- `title` (string)

### `contribos_setup` (~34 tokens)

Exact steps to set up and test a repository, taken from its CI and contributing docs.

Input parameters:

- `repo` (string, required)

### `contribos_diagnose` (~68 tokens)

Explain a failed install or test run: missing dependency, wrong version, service not running, missing env var, flaky test, or a real test failure.

Input parameters:

- `log` (string): the failing command's output
- `output_file` (string): or a file holding that output

### `contribos_check` (~198 tokens)

Pre-submit review of the local branch against the repo's rules and history: scope versus similar past changes, tests, changelog, sign-off, debug leftovers, AI policy, and whether the contributor's own explanation covers the change, AI-disclosure trailers, competing PRs, and (with verify_test) whether the test fails without the fix. Do not write the explanation for the user.

Input parameters:

- `ai_note` (string): how AI was used, e.g. 'Claude Code: drafted the test'
- `base` (string): branch the work started from (default: auto-detect)
- `explain_file` (string): or a file holding it
- `explanation` (string): the contributor's own explanation, as text
- `issue` (integer): issue number, to look for competing PRs
- `path` (string): local checkout
- `verify_test` (string): test command to run with and without the fix

### `contribos_review` (~94 tokens)

Review coach for an open PR: classifies each reviewer comment, shows the code it points at, drafts replies, and lists comments still waiting on the author.

Input parameters:

- `data` (object): or saved review data: author, review_comments, issue_comments, reviews
- `path` (string): local checkout, to show the code each comment points at
- `pr_url` (string): PR URL (needs API access)

### `contribos_claim` (~85 tokens)

Draft the short proposal a contributor posts on an issue before coding (and a vouch introduction where the repo needs one). The human rewrites and posts it; never post it.

Input parameters:

- `issue_url` (string): GitHub issue URL (needs API access)
- `repo` (string): owner/name, when giving title instead of issue_url
- `title` (string)

### `contribos_tone` (~53 tokens)

Check text the human is about to post for machine-written tells, length, and a clear question. Points at problems; the human rewrites.

Input parameters:

- `kind` (string)
- `text` (string, required)

### `contribos_find` (~45 tokens)

Find open issues where a newcomer is actually welcome, with takeability evidence.

Input parameters:

- `language` (string)
- `repos` (array)
- `topic` (string)
