Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00050 | $0.00404 |
| Opus 5 | $0.00025 | $0.00202 |
| Sonnet 5 | $0.00010 | $0.00081 |
| Haiku 4.5 | $0.00005 | $0.00040 |
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 8d 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
- Inspect the current workspace changes with the narrowest useful git commands, normally
git status --shortand focusedgit diffreads. - Identify changed paths, behavioral surfaces, test coverage, risks, and unresolved questions.
- Read
../artifacts/references/visual-explainer-defaults.mdand use thereview-matrixpreset. - Use
../../templates/visual-explainer.htmlas the HTML starting point when helpful. - Save through the
artifacttool 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
styleOverrideswhile keeping the review readable and source-backed.
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.
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.

diff-review-artifact is a skill published in the GitHub repository patleeman/neon-pilot (23 stars, last pushed 1mo ago), licensed MIT. It adds 50 tokens to every session and 404 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
