engineering-codebase-onboarding-review

engineering-codebase-onboarding-review is a skill for Claude Code, Codex from aidi1723/safe-agent-skills. It costs 32 tokens per session (351 once invoked), scanned A, a copy of business-competitive-teardown-review, Apache-2.0.

A review guide for deciding whether a draft about understanding and joining an existing codebase should become a local coding-agent skill. A codebase is the collection of source files and related project materials for a software product.

In plain words
What is it for?
Reviewing the draft’s scope, overlap with existing skills, licensing, permissions, and connector assumptions. It produces an adoption recommendation and a checklist for verification.
Why use it?
It helps reviewers avoid importing untrusted, duplicated, or poorly documented guidance. It also keeps the draft as a reference until its source, permissions, and quality are checked.

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

engineering-codebase-onboarding-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 9d 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.

Origin

This is a copy

81% identical to business-competitive-teardown-review — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Codebase Onboarding Review

When To Use

Use this draft when reviewing the codebase-onboarding metadata-only candidate from claude-skills before deciding whether to author a local OneCode skill, merge it into an existing skill, or keep it reference-only.

Safe Workflow

  1. Identify the task, audience, owner, source domain, target catalog category, and expected artifact.
  2. Compare the candidate with existing trusted Safe-Agent-Skills to avoid duplicate or overlapping guidance.
  3. Draft local OneCode guidance from project requirements and operator review; do not copy upstream skill bodies.
  4. Check provenance, license notes, runtime permissions, and connector assumptions before import.
  5. Produce an adoption recommendation only; Do not execute upstream content or mark this draft trusted.

Expected Output

  • metadata-only candidate summary
  • overlap and merge recommendation
  • local authoring notes
  • required verifier checklist
  • adoption decision: convert, merge, keep reference-only, or reject

Verifier Expectations

  • metadata-only boundary check
  • duplicate skill check
  • provenance and license check
  • import, serial approval, schema-check, maintain-check, and verify before trust

Draft Metadata

  • upstream candidate: codebase-onboarding
  • source domain: engineering
  • source path: engineering/skills/codebase-onboarding
  • mapped category: engineering
  • score: 54
  • priority: P3
  • adoption before draft: reference_only

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
