mozaiks: Skill for Claude Code

.agents/skills/oss-contribution-review/SKILL.md

oss-contribution-review is a skill for Claude Code from BlocUnited-LLC/mozaiks. It costs 33 tokens per session (304 once invoked), scanned A, original, MIT.

A review guide for open-source software changes, covering where a change belongs, what it affects, and what supporting work is needed.

In plain words
What is it for?
Use it before or after editing to review code layers, build and runtime effects, tests, documentation, and risks to public interfaces or project rules.
Why use it?
It helps prevent changes from crossing architectural boundaries, breaking build workflows, or drifting from the project's public agreement.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; installed under .agents/ (shared by several agents).

This is BlocUnited-LLC/mozaiks's own configuration. It tells Claude Code how to work on mozaiks itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mozaiks configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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

oss-contribution-review 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 11d 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

Review $ARGUMENTS against the Mozaiks OSS contribution contract.

Inspect the owning files first. Start from the nearest concrete anchor and classify:

  1. layer changed: universal substrate, framework capability, or hosted product capability
  2. build workflow impact: workflow_sequence, transition, handoff, entrypoint, control-plane route, or none
  3. runtime/platform impact
  4. app workspace impact
  5. tests required
  6. docs, rules, or skills required
  7. contract drift or public-framing risk

Use these anchors when relevant:

  • AGENTS.md
  • CLAUDE.md
  • ARCHITECTURE.md
  • active task skills under .agents/skills/ or .claude/skills/
  • .claude/skills/README.md
  • .claude/rules/architecture-boundaries.md
  • .claude/rules/factory-build-workflows.md
  • .claude/rules/control-plane-refinement.md
  • .claude/rules/testing.md

Return:

  1. Layer changed
  2. Build workflow impact
  3. Runtime/platform impact
  4. App workspace impact
  5. Tests required/run
  6. Docs required/updated
  7. Contract drift risk

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.
