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.

Fable 5.1 $0.00050 $0.00404

Security

Grade A, and why

diff-review-artifact 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 2mo 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

Diff Review Artifact

Create a source-backed visual review of workspace changes, optimized for quickly seeing risk, intent, and follow-up work.

Workflow

  1. Inspect the current workspace changes with the narrowest useful git commands, normally git status --short and focused git diff reads.
  2. Identify changed paths, behavioral surfaces, test coverage, risks, and unresolved questions.
  3. Read ../artifacts/references/visual-explainer-defaults.md and use the review-matrix preset.
  4. Use ../../templates/visual-explainer.html as the HTML starting point when helpful.
  5. Save through the artifact tool with the metadata below.

Metadata Defaults

{
  "action": "save",
  "kind": "html",
  "artifactType": "diff-review",
  "stylePreset": "review-matrix",
  "templateVersion": "visual-explainer-v1",
  "source": {
    "kind": "command",
    "command": "diff-review",
    "paths": ["changed/path"]
  }
}

Set source.paths to the actual changed files or top-level areas covered by the review.

Artifact Shape

  • Start with a summary matrix: area, change, risk, confidence, validation.
  • Group findings by severity or decision impact.
  • Include evidence from specific files or diff hunks without pasting huge source blocks.
  • Distinguish confirmed issues from risks and open questions.
  • Preserve user overrides in styleOverrides while keeping the review readable and source-backed.
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.
