MCPGateway: Skill for Codex

.codex/skills/mcaf-human-review-planning/SKILL.md

mcaf-human-review-planning is a skill for Codex from managedcode/MCPGateway. It costs 76 tokens per session (1,158 once invoked), scanned A, a copy of dotnet-mcaf-human-review-planning, MIT.

A practical plan for reviewing a large AI-generated code change when a person cannot inspect every line. It traces real user and system flows, finds risky boundaries, and ranks the files that deserve attention first.

In plain words
What is it for?
Use it to plan human review of a large generated code drop, prioritize files in a target area, and create a review sequence around key user or operational flows.
Why use it?
It reduces the time needed for manual review while focusing attention on the areas most likely to contain important defects.

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

mcaf-human-review-planning 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 1mo 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

MCAF: Human Review Planning

Trigger On

  • a large AI-generated code drop needs a human review plan
  • the reviewer cannot inspect every line and needs prioritization
  • the user asks which files are highest risk before doing manual review
  • the user names a generated folder and wants a saved review plan for it

Value

  • produce a concrete project delta: code, docs, config, tests, CI, or review artifact
  • reduce ambiguity through explicit planning, verification, and final validation skills
  • leave reusable project context so future tasks are faster and safer

Do Not Use For

  • normal small pull-request review
  • automated bug finding without creating a human review sequence

Inputs

  • the target folder, feature area, or bounded context under review
  • the main user journeys or operational flows involved
  • any known architecture context, adjacent entities, or existing system rules
  • any exact output path the user wants for the saved plan

Quick Start

  1. Read the nearest AGENTS.md and confirm scope and constraints.
  2. Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
  3. Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

  1. Read enough of the target area and its immediate boundaries to understand the generated code before planning review.
  2. Map the natural flow of operations first:
    • sign up or authentication
    • create
    • update
    • register or configure
    • execute primary business action
    • complete, archive, or finalize
  3. Use that flow to derive the most efficient human review sequence.
  4. Use the reviewer's domain knowledge as a force multiplier:
    • compare the generated code against known architecture and existing entities
    • look for places where the new feature should behave like nearby existing flows
    • prioritize boundaries where generated code may drift from established system rules
  5. Identify high-risk review zones:
    • entry points and orchestration layers
    • persistence and state transitions
    • cross-boundary integrations
    • permissions, validation, and invariants
    • side effects such as email, payments, jobs, or notifications
  6. Produce two separate outputs:
    • prioritized review flow
    • prioritized files or modules to inspect
  7. Present both outputs in chat.
  8. If the user asks for a durable artifact, save the plan to the exact docs path they requested; otherwise use docs/AREA/HUMAN_REVIEW_PLAN.md.

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.
