.agents/skills/authoring-issues-prs/SKILL.md

authoring-issues-prs is a skill for Claude Code, Codex from pvliesdonk/markdown-vault-mcp. It costs 99 tokens per session (2,273 once invoked), scanned A, original, MIT.

A set of instructions for writing and submitting GitHub issues and pull requests. GitHub issues track problems or tasks, while pull requests propose code changes for review.

In plain words
What is it for?
Use it when filing a bug, recording a review finding, creating a ticket, or opening a pull request.
Why use it?
It helps route work to the right repository and follow that repository’s rules for clear, focused reports and changes.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is pvliesdonk/markdown-vault-mcp's own configuration. It tells Claude Code and Codex how to work on markdown-vault-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything markdown-vault-mcp configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

authoring-issues-prs 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Authoring issues and pull requests

CONTRIBUTING.md holds the issue rules, the agent-post footer and the three-tier routing; AGENTS.md and .github/PULL_REQUEST_TEMPLATE.md hold the PR rules. This skill adds the order of operations, the sizing procedure behind the limits AGENTS.md sets, and the API steps issue forms cannot perform; it states none of the other rules itself.

Procedure

1. Read CONTRIBUTING.md — now, not from memory

Read CONTRIBUTING.md (repository root) before drafting a single sentence, even if you believe you remember it:

  • "Observation, not work order" and "The uncertainty rule" — issue voice and the [verified: how] / [unverified] markers.
  • "One issue, one observed problem" and the "Remove before posting" table — run your draft through the table before submitting.
  • "Pull requests" — which AGENTS.md sections and template govern a PR, and the merge style.
  • "Where to send fixes" — the routing walked in step 2.
  • "Agent-authored posts" — the footer every post ends with, and how to read earlier posts under the account holder's name (step 8).

Where this skill and CONTRIBUTING.md disagree, the file wins.

2. Route before writing

Decide the repo before writing: ask which file a fix would change, and look that file up in CONTRIBUTING.md's "Where to send fixes" (library, template or domain). When the tier is unclear, file where you think it belongs and say so in the issue with an [unverified] marker.

3. Search for duplicates

Search the target repo's issues — open and closed — before filing:

gh issue list --repo OWNER/REPO --state all --search "<key terms>"

Match on the observation, not the wording. If the problem is already on file, comment on the existing issue rather than opening a twin; if a closed issue shows it regressed, say that in the new issue and link it.

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.
