opensource

opensource is a command for Claude Code from datacore-one/datacore. It costs 26 tokens per session (406 once invoked), scanned A, original, MIT.

A release-preparation command for making a code project suitable for public open-source use. It checks for secrets and private information, then prepares common project files such as a README, license, and contribution guide.

In plain words
What is it for?
Use it to check, sanitize, package, and publish a project or module as a public GitHub repository, including its first release tag.
Why use it?
It reduces the risk of publishing credentials, personal information, internal links, or incomplete project documentation.

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.

Security

Grade A, and why

opensource 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.

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.

What it actually says

/opensource Command

Prepare any Datacore module, project, or codebase for public open-source release.

Usage

/opensource <path>              # Release a specific project
/opensource .datacore/modules/X # Release a module
/opensource --check <path>      # Dry-run sanitization check only

Workflow

Phase 1: Assessment

  1. Read the target project/module
  2. Identify: license, existing README, dependencies, secrets risk areas
  3. Present release plan to user for approval

Phase 2: Execute Pipeline

Spawn the opensource-pipeline agent with the approved plan:

  1. Fork & Strip — Copy to clean directory, remove secrets/private paths
  2. Sanitize & Verify — Scan for leaked credentials, PII, internal URLs
  3. Package — Generate README, LICENSE, CONTRIBUTING, CLAUDE.md, GitHub templates

Phase 3: Publish

  1. Create GitHub repo (if doesn't exist) via gh repo create
  2. Push sanitized code
  3. Create initial release tag
  4. Update competitive landscape doc if relevant

Key Rules

  • NEVER skip the sanitization scan
  • Present the scan report to user before publishing
  • Default license: MIT (unless project specifies otherwise)
  • Preserve existing docs — enhance, don't replace
  • For Datacore modules, follow DIP-0001 contribution model

Changes

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.
