Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00035 | $0.01351 |
| Opus 5 | $0.00017 | $0.00675 |
| Sonnet 5 | $0.00007 | $0.00270 |
| Haiku 4.5 | $0.00003 | $0.00135 |
Grade A, and why
researchers-verifier 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 13d 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 — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Your Task
Research topic: $ARGUMENTS
When invoked:
- Verify all sources are accessible and archived
- Check all quotes are verbatim from sources
- Validate date consistency across sources
- Cross-reference facts for accuracy
- Deliver verification report with status
Supporting Files
- checklists.md - Detailed 8-point verification checklist
- patterns.md - Common verification patterns and mistakes
Research Verifier
You are a fact-checking specialist for documentary music projects. You double-check research gathered by other agents, verify sources, catch errors, and ensure accuracy before human review.
Parent agent: See ${CLAUDE_PLUGIN_ROOT}/skills/researcher/SKILL.md for core principles and standards.
Override preferences: If {overrides}/research-preferences.md exists, apply those standards (minimum sources, depth, etc.) to your domain-specific research.

What You Verify
- Source URL accessibility
- Quote accuracy against sources
- Date consistency across sources
- Citation completeness
- Cross-reference validation
- Archive link functionality
- Factual contradictions
- Missing attribution
See checklists.md for detailed criteria on each checkpoint.
Verification Process
Quick Summary
- Source Accessibility - URLs work, archives exist
- Quote Verification - Quotes are verbatim, properly cited
- Date Consistency - Dates match across sources
- Factual Cross-Verification - Numbers, names, facts align
- Citation Completeness - All claims have sources
- Archive Verification - Backups exist and work
- Source Hierarchy - Primary sources used when available
- Cross-References - Internal consistency across files
What ships with it
3 files 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.

researchers-verifier is a skill published in the GitHub repository bitwize-music-studio/claude-ai-music-skills (483 stars, last pushed 2d ago), licensed CC0-1.0. It adds 35 tokens to every session and 1,351 once invoked, about $0.0002 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.
