codebase-onboarding

Analyze a codebase and generate onboarding documentation for engineers, tech leads, and contractors. Fast fact-gathering and repeatable onboarding outputs. Use when onboarding a new engineer, writing architecture-overview docs for a new project, or producing tech-lead briefings for unfamiliar repos.

Quality

Content

50%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-organized with a sensible Quick Start and audience-tailored workflow, but its core executable path depends on a script and template files that are absent from the bundle, and it lacks validation checkpoints. Some padding (Overview, Core Capabilities) duplicates the description abstractly.

Suggestions

Ship the referenced bundle files (scripts/codebase_analyzer.py, references/onboarding-template.md, references/output-format-templates.md) or remove the references so no guidance points to files that do not exist.

Add an explicit validation step to the Recommended Workflow (e.g., verify generated setup instructions run in a clean environment before finalizing docs), promoting the pitfall into a workflow checkpoint.

Trim the Overview and Core Capabilities sections — they restate the description and list abstract capabilities — and spend the saved tokens on a concrete example of analyzer output or a filled template snippet.

DimensionReasoningScore

Conciseness

The "Overview" section repeats the frontmatter description almost verbatim and "Core Capabilities" lists abstract capabilities ("Architecture and stack discovery", "Audience-aware documentation framing") that add little beyond "When to Use" and "Recommended Workflow"; both could be tightened or removed.

3 / 5

Actionability

The Quick Start gives concrete bash commands ("python3 scripts/codebase_analyzer.py /path/to/repo", "--json"), but the script and both referenced templates ("references/onboarding-template.md", "references/output-format-templates.md") do not exist in the bundle, so the guidance is specific yet not actually executable as shipped.

3 / 5

Workflow Clarity

The Recommended Workflow is a coherent 4-step sequence (run analyzer, capture signals, fill template, tailor by audience), but no validation or verification checkpoints appear — validation is only mentioned as a pitfall ("Writing docs without validating setup commands on a clean environment") rather than as a workflow step.

3 / 5

Progressive Disclosure

The body is cleanly sectioned and appropriately delegates template content to reference files, but the bundle contains no references/ or scripts/ directories at all, so the three clearly-signaled references are dangling and the disclosure structure does not actually exist.

Description

78%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that clearly answers both what the skill does and when to use it, in third person with concrete trigger phrases. Its main gaps are limited action specificity beyond the two core verbs and a few missing natural synonym phrases.

DimensionReasoningScore

Specificity

"Analyze a codebase and generate onboarding documentation" names the domain and two concrete actions, but "Fast fact-gathering and repeatable onboarding outputs" are characteristics rather than actions, leaving coverage short of the several specific actions a 4 requires.

3 / 5

Completeness

Both what ("Analyze a codebase and generate onboarding documentation for engineers, tech leads, and contractors") and when ("Use when onboarding a new engineer, writing architecture-overview docs for a new project, or producing tech-lead briefings for unfamiliar repos") are explicitly answered with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural phrases users would say are present ("onboarding a new engineer", "architecture-overview docs", "tech-lead briefings", "unfamiliar repos"), but common variations like "new team member", "project handoff", or "get up to speed on a repo" are missing.

4 / 5

Distinctiveness Conflict Risk

The onboarding-documentation framing with named audiences is a clear niche, but "Analyze a codebase" and "architecture-overview docs" overlap with general repo-documentation and code-exploration skills, so minor conflict risk remains.
