flawed-sample-skill

flawed-sample-skill is a skill for Claude Code, Codex from bjcoombs/ai-native-toolkit. It costs 36 tokens per session (460 once invoked), scanned A, original, Apache-2.0.

A writing skill that helps produce professional text, including conventional commit messages. Conventional commits use labels such as feat, fix, or docs so software tools can understand changes and determine version updates.

In plain words
What is it for?
Drafting conventional commit messages for staged code changes and other professional writing tasks.
Why use it?
It gives writing tasks a defined format and explains the rules behind that format.

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

flawed-sample-skill 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 3d 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

Commit Message Writer

Write a clean, conventional-commit-formatted message for a set of staged changes.

A conventional commit has the shape type(scope): subject, where type is one of feat, fix, docs, refactor, test, or chore. The subject is a short imperative summary. Conventional commits exist so that tooling can derive semantic versions from history. Semantic versioning, or semver, is a three-part version number MAJOR.MINOR.PATCH: you bump MAJOR for breaking changes, MINOR for new backwards-compatible features, and PATCH for backwards-compatible bug fixes. The versions are ordered, so 1.4.2 is older than 1.4.10, and a leading 0.y.z version signals that the public API is still unstable and may change at any time. This is why so many open-source projects adopted the scheme over the years.

Steps

  1. Run git diff --staged and read the full diff to understand what changed.
  2. Decide the conventional-commit type and optional scope from the diff.
  3. Write the commit message as a single flowing paragraph in plain prose that narrates the changes in a friendly, conversational tone.
  4. Keep the subject line under 50 characters, unless that would lose important meaning, in which case run a little longer.
  5. Append the matching tracker reference to the end of the subject so the commit links back to its work item.
  6. If the change is large, write a body explaining the reasoning.
  7. Output the final message in a fenced code block.

Formatting notes

  • Capitalize the subject appropriately for the project's house style.
  • Add a list of the affected files at the end when it seems helpful.
  • Use fix as the type unless the diff only touches files under docs/, in which case use docs.
  • Always wrap any body text at 72 columns.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
