Bridge Contribute — give improvements back upstream

This is the skill the open-bridge community uses to feed features and improvements back: it turns work on your user/* branch into a clean, reviewed pull request against bks-lab/open-bridge (or your org's overlay repo) — and it refuses to ship anything the content-safety gate flags. Protecting your own customer names, personal data, and internal paths is a hard gate, not a checkbox.

Read the referenced file ONLY when triggered.

Arguments

Decision Tree

User wants to...
├── Scan branch for contributions            → references/workflow.md
├── Contribute a specific file/dir           → references/workflow.md ({path})
├── Adapt/generalize content first           → references/workflow.md § Adapt mode
├── Promote whole commits by scope           → use the bridge-promote skill (/promote)
└── Questions about scope routing            → docs/org-overlays.md (tier model)

Safety (MANDATORY — the reason this skill exists)

No PR is created until the two-layer gate passes for the exact outgoing file set:

1. python3 scripts/no-scrub-leak.py {files} — scripts/no-scrub-leak.py is a shared repo-root utility shipped with the Bridge repo itself, not a file inside this skill's own directory. It checks universal classes (absolute user paths, key/token shapes, merge-conflict markers) plus your own roster from scripts/leak-patterns-internal.txt (local-only, never shipped — you maintain your customer/PII regexes there; the shipped scanner cannot know them).
2. The per-destination blocklist scan from rules/promote-safety.md — the OSS upstream uses the strictest list.

REFUSE path: personal-PII or roster hits exclude the affected files — no override flag, no "it's just an example". Remediation: --adapt, re-scan, only a clean re-scan unblocks. Clean files in the same batch still ship.

Relationship to /promote

/promote (bridge-promote skill) moves whole commits by scope: routing — the lightweight path when your branch has clean per-commit scope discipline. /contribute works file-level, with adaptation and always ending in a PR — the path for mixed branches and for first-time community contributions.
