GitHub Safe Publisher

Overview

Use this skill to turn private project material into public-safe GitHub artifacts such as case studies, skill releases, README updates, demo notes, and example prompts. The skill produces a safety verdict and concrete next steps; it must not auto-commit, auto-push, publish, upload, send, or share anything without explicit human review.

Workflow

1. Identify the intended public artifact: skill, case study, README section, demo screenshot note, example prompt, template, or changelog.
2. Read references/public-safety-boundaries.md before deciding what can be reused, generalized, or removed.
3. Work from a copy or rewritten summary, not the private original. Prefer a sanitized draft folder before touching a public repo.
4. Remove or replace sensitive details: credentials, account data, client material, raw prompts, logs, databases, exports, local paths, private source, and screenshots with private UI.
5. Run the scanner on the proposed public folder:

python scripts/scan_public_safety.py path/to/public-candidate --no-baseline

1. Read references/release-workflow.md before staging changes.
2. Require manual review of git status --short, the unstaged diff, and the staged diff before any commit or push.

Verdicts

Return one of these verdicts in every review:

• BLOCK: Real secrets, credentials, raw private data, client-identifying material, local machine paths, databases, exports, logs, or unintended source files are present.
• REVIEW: The artifact is probably publishable after specific human checks or rewrites.
• READY: The artifact uses public-safe examples, passes the scanner, and has a clean manual diff review.

If blocked, explain the minimum fix. Do not rewrite blocked material into a public repo until the sensitive source is removed or generalized.

Sanitization Rules

• Replace real people, businesses, accounts, emails, phone numbers, domains, addresses, and project codenames with neutral examples.
• Replace credentials with placeholders such as YOUR_API_KEY_HERE.
• Convert raw private notes into public explanations; do not copy memory files, chat logs, prompts, or operational strategy verbatim.
• Publish patterns, workflows, and lessons. Keep implementation source, deployment details, private data, and system-of-record content private unless the user explicitly confirms they are public-safe.
• For screenshots, crop or recreate them with fake data. Do not publish account menus, browser tabs, analytics, emails, invoices, API dashboards, or file paths.

Scanner

Use scripts/scan_public_safety.py for a deterministic first pass. Treat it as a guardrail, not proof of safety.

Recommended commands:

python scripts/scan_public_safety.py path/to/candidate
python scripts/scan_public_safety.py path/to/candidate --no-baseline --json
python scripts/scan_public_safety.py path/to/candidate --no-baseline

The scanner checks risky filenames, file extensions, binary-like artifacts, local path patterns, credential terms, token formats, private-key blocks, and private/client wording. Folder scans use .public-safety-baseline.json when present to suppress known review findings; use --no-baseline to see the raw scan. A clean scan still requires human diff review.

Git Safety

Scanner reports withhold matched text and absolute input locations. Relative filenames may still identify private work, so keep reports private. Linked inputs are refused; unreadable content and incomplete enumeration prevent readiness. Excluded build/dependency folders and binary content are not a complete content audit.

The baseline file itself is scanned. Existing review fingerprints remain compatible for unchanged content, but blocking findings are never suppressed. Inspect matches privately at their locations rather than copying sensitive lines into chat or logs. Review the exact proposed release file list separately.

• Never run broad staging commands such as git add . unless the user has already reviewed the whole repo state.
• Prefer staging named files only after inspecting them.
• Always inspect:

git status --short
git diff -- path/to/file
git diff --cached

• Do not commit or push unless the user explicitly asks for that action after the safety review is clean.

Output Format

When preparing or reviewing a public candidate, respond with:

1. Verdict: BLOCK, REVIEW, or READY.
2. Public artifact type and target repo/folder.
3. Files inspected or created.
4. Scanner result summary.
5. Remaining manual checks.
6. Exact next commands, if any, without auto-running publish actions.
