mal-mcp: Skill for Claude Code

.agents/skills/changelog-style/SKILL.md

changelog-style is a skill for Claude Code, Codex from Grinv/mal-mcp. It costs 50 tokens per session (1,489 once invoked), scanned A, a copy of changelog-style, MIT.

A procedure for turning a range of code commits into short entries in CHANGELOG.md, the file that records changes between software releases.

In plain words
What is it for?
Use it when finishing a pull request or preparing a release, including updates to the Unreleased section or a new version heading.
Why use it?
It keeps release notes brief, consistent, and focused on user-visible changes instead of implementation details.

Skill for Claude CodeCodex

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

This is Grinv/mal-mcp's own configuration. It tells Claude Code and Codex how to work on mal-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 mal-mcp configures →

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

changelog-style 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 9d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Changelog entries: style & workflow

Entries in CHANGELOG.md should be short and self-describing. Style reference: common-changelog. The workflow below (how to actually produce those entries from commit history) is synthesized from three changelog-generation agent skills: GoogleChromeLabs/changelog-generation-skill, ComposioHQ/awesome-claude-skills/changelog-generator, and glincker/changelog-generator.

Style

  • One line per entry — two only if it genuinely needs a "why". Common-changelog is stricter here ("a change should be brief and to the point, no more than one line long"); we allow a second line for a real rationale. Skip mechanism/implementation detail; that belongs in the commit message or PR description, not the changelog. Concrete gut-check: after writing an entry, measure the prose (excluding the trailing link) — past ~150 chars you're burying the fact, not stating it; reread it and cut, don't just eyeball "does this look like one line" (a long single physical line with no embedded newline still fails this rule even though it dodges the separate "no dangling link" issue below) — e.g. generalize the affected set instead of enumerating every affected tool/field by name.
  • Imperative, present tense: "Add X", "Fix Y" — not "Added X" / "Fixed Y".
  • Self-describing: a reader skimming just the bullet — without its ### Added / ### Fixed category heading for context — should still understand the change and its effect.
  • Exclude dev-only/maintenance changes: dotfile tweaks, dev-dependency bumps, test-only changes, pure code-style edits — these are not interesting to someone consuming the released package, so they don't get an entry; put them in the commit message instead. Exception: a refactor that could have user-visible side effects (behavior change, perf, a fixed edge case) still gets an entry describing that effect, not the refactor itself.
  • Link commits/PRs/issues: reference the commit that made the change, and the PR or issue too when one exists. Exception: a version whose entire content is one single commit — don't repeat the identical link after every bullet; put one link at the section level instead (e.g. "Everything below is one commit: [<sha>](...)." right under the version heading).
  • No dangling link line: keep an entry and its link(s) on one physical source line, even if long. GitHub renders a single soft-wrapped newline inside a list item as a real line break, so a wrapped entry shows its link stranded alone on the next line instead of reading as one continuous bullet.

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.
