implementation_review

implementation_review is a skill for Claude Code from MarcusJellinghaus/mcp-workspace. It costs 8 tokens per session (355 once invoked), scanned A, original, MIT.

A compact review of a code change by examining its difference from the project’s current code and checking for bugs, unnecessary debug output, broken behavior, and architecture violations.

In plain words
What is it for?
Reviewing a feature branch, checking implementation logic, assessing tests and project structure, and reporting critical issues, suggestions, and strengths.
Why use it?
It gives developers a focused list of problems and suggestions before a change is merged, without changing the code.

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

implementation_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 6d 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

Implementation Review (Code Review)

First, ensure we're up to date: Call mcp__mcp-workspace__git with command "fetch" and args ["origin"]. Use mcp__mcp-workspace__git with command "status" to check working directory state. Call mcp__mcp-workspace__check_branch_status.

Confirm and display the current feature branch name.


Then run the code review:

Code Review Request

Use mcp__mcp-workspace__git with command "diff" to get the changes to review.

No need to run all checks; do not use pylint warnings. Feel free to further analyse any mentioned files and/or the file structure.

Focus Areas:

  • Logic errors or bugs
  • Tests for __main__ functions should be removed (not needed)
  • Unnecessary debug code or print statements
  • Code that could break existing functionality
  • Compliance with existing architecture principles, see docs/architecture/architecture.md

Output Format:

  1. Summary - What changed (1-2 sentences)
  2. Critical Issues - Must fix before merging
  3. Suggestions - Nice to have improvements
  4. Good - What works well

Do not perform any action. Just present the code review.

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.
