mcp4openapi: Skill for Claude Code

.claude/skills/use-correct-github-review-comment-enums/SKILL.md

use-correct-github-review-comment-enums is a skill for Claude Code from davidruzicka/mcp4openapi. It costs 44 tokens per session (358 once invoked), scanned A, original, MIT.

A guide for using the correct fixed values when posting review comments on GitHub pull requests. Pull requests are proposed code changes, and review comments can be attached to a line or an entire file.

In plain words
What is it for?
Use it when creating inline or file-level pull-request comments through GitHub tools, or when correcting an enum validation error from a previous comment attempt.
Why use it?
It prevents GitHub from rejecting comments because fields such as comment location or page side use an invalid value or capitalization.

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

use-correct-github-review-comment-enums 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.

What it actually says

Goal

Prevent avoidable GitHub MCP tool failures caused by invalid enum values or casing in review-comment payloads.

When to Use

  • You call mcp__github__add_comment_to_pending_review.
  • You create or submit PR review comments with enum fields such as subjectType or side.
  • A prior tool call failed with GraphQL validation mentioning enum mismatch.

Rules

  1. Validate enum fields before sending:
  • subjectType must be LINE or FILE.
  • side and startSide should use LEFT or RIGHT when present.
  1. Prefer subjectType: LINE for inline code comments.
  2. Include path and line for inline comments; use subjectType: FILE only for file-level comments.
  3. If a validation error reports enum mismatch, retry once with corrected enum casing/values without changing comment meaning.
  4. Do not repeat retries beyond one automatic correction attempt.
  5. Keep review text unchanged while fixing transport/schema fields.

Procedure

  1. Build comment payload and preflight-check enum fields.
  2. Send tool call.
  3. If response contains enum-validation error:
  • map invalid enum values to valid constants (LINE/FILE, LEFT/RIGHT),
  • resend exactly once.
  1. Confirm comment presence by reading review comments after successful submission.

Quick Reference

  • Correct: subjectType: "LINE"
  • Incorrect: subjectType: "line"
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.
