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 | $0.00160 | $0.04264 |
| Opus 5 | $0.00080 | $0.02132 |
| Sonnet 5 | $0.00032 | $0.00853 |
| Haiku 4.5 | $0.00016 | $0.00426 |
Grade A, and why
sketch-checker 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 12d 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.

Sketch Checker: Metal Band Fascist Ties Research
Overview
Research whether a metal band has ties to far-right, NSBM (National Socialist Black Metal), or fascist movements. Produces a sourced "sketch report" with dual-axis verdicts using the Hellseatic community convention.
This skill uses a 3-phase parallel research methodology: cast a wide net across community databases, music industry records, and press/interviews simultaneously, then follow up on specific leads, then synthesize into a structured verdict.
Output: A markdown report saved to sketch-reports/{band-name}.md plus a concise conversation summary.
Rating System
Historical Tier
Evaluates the band's entire history from formation to present.
| Tier | Meaning | Criteria |
|---|---|---|
| Safe | No connections found | No sketch ties in any research phase. Clean across members, labels, splits, and statements. |
| Mild Sketch | Tangential or ambiguous connections | One-off split with a sketch band. Appeared on a compilation with sketch acts. Single member's very old side project had sketch ties but was brief. |
| Moderate Sketch | Pattern of connections or significant single incident | Multiple splits/collaborations with sketch acts. Played known sketch festivals. Member(s) with sustained sketch side projects. Dog-whistle lyrics that go beyond "edgy." |
| Major Sketch | Direct ideological engagement | Band members made public statements supporting far-right ideology. Lyrics with explicit NS themes. Close, sustained ties to NS organizations or labels. Band logo/imagery incorporates explicit NS symbolism (beyond standard BM aesthetic). |
| Nazi | Openly NSBM or white supremacist | Self-identifies as NSBM. Explicit NS lyrics across discography. Active in NS organizations. No ambiguity. |
Current Status
Evaluates the band's present-day stance and activity (last ~3 years).
| Tier | Meaning | Criteria |
|---|---|---|
| Safe | Currently clean | No current sketch ties. May have distanced themselves from past connections. Active statements or actions against far-right. |
| Mild Sketch | Minor current concerns | Still on a label with some sketch roster. Hasn't explicitly denounced past connections but isn't actively sketch. |
| Moderate Sketch | Active sketch-adjacent behavior | Currently playing sketch festivals. Active collaborations with sketch acts. Ambiguous statements when confronted. |
| Major Sketch | Active ideological engagement | Recent far-right statements. Current NS-adjacent projects. Active in sketch scenes. |
| Nazi | Currently active NSBM/WS | Self-identifies as NSBM. Active NS organizing. Explicit current propaganda. |
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.

sketch-checker is a skill published in the GitHub repository sam-dumont/claude-skills (39 stars, last pushed 6mo ago), licensed MIT. It adds 160 tokens to every session and 4,264 once invoked, about $0.0008 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.
