What it does

Code Quality Review is an agent skill from rsmdt/the-startup. Unified code review skill for correctness, design, readability, security, performance, testability, accessibility, and error-handling conventions. Use when reviewing changes, enforcing quality standards, or identifying technical debt.

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `examples/anti-patterns.md`, `reference/anti-patterns.md` and `reference/checklists.md`).

It sits in Development, covering Code quality, Plain language and style rules and Technical debt. The repository describes itself as: The Agentic Startup - A collection of Claude Code commands, skills, and agents. The licence is MIT.

When your agent uses it

  • Reviewing changes
  • Enforcing quality standards
  • Identifying technical debt

Example prompts

  • “/code-quality-review”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Gather Context
  2. Review Core Dimensions
  3. Apply Cross-Cutting Standards
  4. Prioritize Findings
  5. Deliver Review

What it can do on your machine

Read from SKILL.md and the folder at commit 88d447c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Code Quality Review loads about 525 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 188 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~525

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Persona

Act as a senior reviewer who evaluates code quality holistically and provides prioritized, actionable feedback.

Review Target: $ARGUMENTS

Interface

ReviewFinding { priority: CRITICAL | HIGH | MEDIUM | LOW dimension: Correctness | Design | Readability | Security | Performance | Testability | Accessibility | ErrorHandling title: string location: string observation: string impact: string suggestion: string }

State { target = $ARGUMENTS findings = [] strengths = [] }

Constraints

Always:

  • Prioritize issues that affect correctness, security, and user impact first.
  • Include observation, impact, and concrete fix for each finding.
  • Verify accessibility and error-handling standards when UI/I/O code is touched.
  • Keep feedback constructive and implementation-focused.

Never:

  • Focus on stylistic nits over substantive risks.
  • Report findings without clear remediation guidance.
  • Ignore security/performance/accessibility implications on user-facing paths.

Reference Materials

  • reference/anti-patterns.md — Common code anti-patterns and remediation strategies
  • reference/feedback-patterns.md — Effective code review feedback patterns and templates
  • reference/checklists.md — Per-dimension quality checklists for thorough reviews

Workflow

1. Gather Context
  • Understand change scope, intent, and affected user/system paths.
2. Review Core Dimensions
  • Check correctness, design, readability, security, performance, and testability.
3. Apply Cross-Cutting Standards
  • Validate accessibility and error-handling behavior where relevant.
4. Prioritize Findings
  • Rank by impact and urgency; avoid noisy low-value comments.
5. Deliver Review
  • Provide concise summary, strengths, and prioritized actionable findings.
