A contribution checklist for deciding whether and how to work on an issue in an external GitHub repository. It requires checking the repository's contribution policy before implementation.

Use it before forking, cloning for implementation, coding, or opening a pull request for an external repository issue or feature.

It prevents wasted work and helps avoid choosing a contribution path that the project does not accept.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.02151
Opus 5.5	$0.00000	$0.00860
Sonnet 5.5	$0.00000	$0.00430
Haiku 4.5	$0.00000	$0.00215

Security

Grade A, and why

gitworthy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/agent-plugins-check.ts, scripts/bench-frozen.ts, scripts/docs-links.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use gitworthy before spending time on an external repository issue or feature request.

Mandatory contribution loop

Never invert this order. Scout and execute are separate lanes; execute never skips gates.

1. contrib_policy   → 2. hunt/scan (optional)  → 3. worth_check
        ↓
4. ledger record / claim intent  → 5. worth_check again (apply-lane revalidation)
        ↓
6. fork  → 7. repro  → 8. implement  → 9. review  → 10. PR or comment

Gate 1: `contrib_policy` before fork, implement, or PR

Run contribution policy before forking, cloning for implementation, or opening a PR:

npx gitworthy policy owner/repo --json

Or use npx gitworthy scan owner/repo --json / npx gitworthy hunt … only as tracker triage; follow policy reminders when no cached policy exists.

Do not fork or implement until policy is read and the contribution path is chosen (see path matrix below).

Gate 2: Path matrix from policy signals

Pick exactly one contribution path from contrib_policy evidence before investing:

Path	When to use	Deliverable
pr	Default when policy allows PRs; no `no_pr_path`; no security-only channel	Fork → branch → PR
issue_comment_patch	`issue_first_or_alignment` in policy; or `no_pr_path` with a forum/discussion/issue feedback channel	Repro + minimal patch or steps in an issue comment (or linked discussion)
security_report	`SECURITY.md` or policy excerpt requires private disclosure	Report via stated channel; do not open a public PR for the vulnerability
skip	`worth_check` SKIP; or `no_pr_path` with no actionable alternate channel; or policy forbids the change type	Do not invest; pick the next queue item

When no_pr_path is present, read feedback_channel in evidence and map it to issue_comment_patch or security_report — never default to pr.

Gate 3: Hunt loop (perf)

Wall time is usually N × worth_check, not one slow check. Prefer a narrow funnel:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gitworthy is a skill published in the GitHub repository trippyogi/gitworthy (2 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,151 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
