Opensource Pipeline

Open-source pipeline: fork, sanitize, and package private projects for safe public release. Chains 3 agents (forker, sanitizer, packager). Triggers: '/opensource', 'open source this', 'make this public', 'prepare for open source'. Use when a private project must be forked, stripped of secrets, and packaged for public release.

What is this skill?

Safely open-source any project through a 3-stage pipeline: Fork (strip secrets) → Sanitize (verify clean) → Package (CLAUDE.md + setup.sh + README).

When to use

  • User says "open source this project" or "make this public"
  • User wants to prepare a private repo for public release
  • User needs to strip secrets before pushing to GitHub
  • User invokes /opensource fork, /opensource verify, or /opensource package

Commands

CommandAction
/opensource fork PROJECTFull pipeline: fork + sanitize + package
/opensource verify PROJECTRun sanitizer on existing repo
/opensource package PROJECTGenerate CLAUDE.md + setup.sh + README
/opensource listShow all staged projects
/opensource status PROJECTShow reports for a staged project

Protocol

/opensource fork PROJECT

Full pipeline — the main workflow.

Step 1: Gather Parameters

Resolve the project path. If PROJECT contains /, treat as a path (absolute or relative). Otherwise check: current working directory, $HOME/PROJECT, then ask the user.

SOURCE_PATH="<resolved absolute path>"
STAGING_PATH="$HOME/opensource-staging/${PROJECT_NAME}"

Ask the user:

  1. "Which project?" (if not found)
  2. "License? (MIT / Apache-2.0 / GPL-3.0 / BSD-3-Clause)"
  3. "GitHub org or username?" (default: detect via gh api user -q .login)
  4. "GitHub repo name?" (default: project name)
  5. "Description for README?" (analyze project for suggestion)

Step 2: Create Staging Directory

bash
mkdir -p $HOME/opensource-staging/

Step 3: Run Forker Agent

Spawn the opensource-forker agent:

Agent(
  description="Fork {PROJECT} for open-source",
  subagent_type="opensource-forker",
  prompt="""
Fork project for open-source release.

Source: {SOURCE_PATH}
Target: {STAGING_PATH}
License: {chosen_license}

Follow the full forking protocol:
1. Copy files (exclude .git, node_modules, __pycache__, .venv)
2. Strip all secrets and credentials
3. Replace internal references with placeholders
4. Generate .env.example
5. Clean git history
6. Generate FORK_REPORT.md in {STAGING_PATH}/FORK_REPORT.md
"""
)

Wait for completion. Read {STAGING_PATH}/FORK_REPORT.md.

Step 4: Run Sanitizer Agent

Spawn the opensource-sanitizer agent:

Agent(
  description="Verify {PROJECT} sanitization",
  subagent_type="opensource-sanitizer",
  prompt="""
Verify sanitization of open-source fork.

Project: {STAGING_PATH}
Source (for reference): {SOURCE_PATH}

Run ALL scan categories:
1. Secrets scan (CRITICAL)
2. PII scan (CRITICAL)
3. Internal references scan (CRITICAL)
4. Dangerous files check (CRITICAL)
5. Configuration completeness (WARNING)
6. Git history audit

Generate SANITIZATION_REPORT.md inside {STAGING_PATH}/ with PASS/FAIL verdict.
"""
)

Wait for completion. Read {STAGING_PATH}/SANITIZATION_REPORT.md.

If FAIL: Show findings to user. Ask: "Fix these and re-scan, or abort?"

  • If fix: Apply fixes, re-run sanitizer (maximum 3 retry attempts — after 3 FAILs, present all findings and ask user to fix manually)
  • If abort: Clean up staging directory

If PASS or PASS WITH WARNINGS: Continue to Step 5.

Step 5: Run Packager Agent

Spawn the opensource-packager agent:

Agent(
  description="Package {PROJECT} for open-source",
  subagent_type="opensource-packager",
  prompt="""
Generate open-source packaging for project.

Project: {STAGING_PATH}
License: {chosen_license}
Project name: {PROJECT_NAME}
Description: {description}
GitHub repo: {github_repo}

Generate:
1. CLAUDE.md (commands, architecture, key files)
2. setup.sh (one-command bootstrap, make executable)
3. README.md (or enhance existing)
4. LICENSE
5. CONTRIBUTING.md
6. .github/ISSUE_TEMPLATE/ (bug_report.md, feature_request.md)
"""
)

Step 6: Final Review

Present to user:

Open-Source Fork Ready: {PROJECT_NAME}

Location: {STAGING_PATH}
License: {license}
Files generated:
  - CLAUDE.md
  - setup.sh (executable)
  - README.md
  - LICENSE
  - CONTRIBUTING.md
  - .env.example ({N} variables)

Sanitization: {sanitization_verdict}

Next steps:
  1. Review: cd {STAGING_PATH}
  2. Create repo: gh repo create {github_org}/{github_repo} --public
  3. Push: git remote add origin ... && git push -u origin main

Proceed with GitHub creation? (yes/no/review first)

Step 7: GitHub Publish (on user approval)

bash
cd "{STAGING_PATH}"
gh repo create "{github_org}/{github_repo}" --public --source=. --push --description "{description}"

/opensource verify PROJECT

Run sanitizer independently. Resolve path: if PROJECT contains /, treat as a path. Otherwise check $HOME/opensource-staging/PROJECT, then $HOME/PROJECT, then current directory.

Agent(
  subagent_type="opensource-sanitizer",
  prompt="Verify sanitization of: {resolved_path}. Run all 6 scan categories and generate SANITIZATION_REPORT.md."
)

/opensource package PROJECT

Run packager independently. Ask for "License?" and "Description?", then:

Agent(
  subagent_type="opensource-packager",
  prompt="Package: {resolved_path} ..."
)

/opensource list

bash
ls -d $HOME/opensource-staging/*/

Show each project with pipeline progress (FORK_REPORT.md, SANITIZATION_REPORT.md, CLAUDE.md presence).

/opensource status PROJECT

bash
cat $HOME/opensource-staging/${PROJECT}/SANITIZATION_REPORT.md
cat $HOME/opensource-staging/${PROJECT}/FORK_REPORT.md

Staging Layout

$HOME/opensource-staging/
  my-project/
    FORK_REPORT.md           # From forker agent
    SANITIZATION_REPORT.md   # From sanitizer agent
    CLAUDE.md                # From packager agent
    setup.sh                 # From packager agent
    README.md                # From packager agent
    .env.example             # From forker agent
    ...                      # Sanitized project files

Anti-Patterns

  • Never push to GitHub without user approval
  • Never skip the sanitizer — it is the safety gate
  • Never proceed after a sanitizer FAIL without fixing all critical findings
  • Never leave .env, *.pem, or credentials.json in the staging directory

Best Practices

  • Always run the full pipeline (fork → sanitize → package) for new releases
  • The staging directory persists until explicitly cleaned up — use it for review
  • Re-run the sanitizer after any manual fixes before publishing
  • Parameterize secrets rather than deleting them — preserve project functionality
