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 | $0.00013 | $0.01200 |
| Opus 5 | $0.00006 | $0.00600 |
| Sonnet 5 | $0.00003 | $0.00240 |
| Haiku 4.5 | $0.00001 | $0.00120 |
Grade A, and why
validate 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 yesterday.
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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/validate - Validate Analysis Before Sharing
If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.
Review an analysis for accuracy, methodology, and potential biases before sharing with stakeholders. Generates a confidence assessment and improvement suggestions.
Usage
/validate <analysis to review>
The analysis can be:
- A document or report in the conversation
- A file (markdown, notebook, spreadsheet)
- SQL queries and their results
- Charts and their underlying data
- A description of methodology and findings
Workflow
1. Review Methodology and Assumptions
Examine:
- Question framing: Is the analysis answering the right question? Could the question be interpreted differently?
- Data selection: Are the right tables/datasets being used? Is the time range appropriate?
- Population definition: Is the analysis population correctly defined? Are there unintended exclusions?
- Metric definitions: Are metrics defined clearly and consistently? Do they match how stakeholders understand them?
- Baseline and comparison: Is the comparison fair? Are time periods, cohort sizes, and contexts comparable?
2. Check for Common Analytical Errors
Systematically review for:
Data completeness:
- Missing data that could skew results (e.g., nulls in key fields, missing time periods)
- Data freshness issues (is the most recent data actually complete or still loading?)
- Survivorship bias (are you only looking at entities that "survived" to the analysis date?)
Statistical issues:
- Simpson's paradox (trend reverses when data is aggregated vs. segmented)
- Correlation presented as causation without supporting evidence
- Small sample sizes leading to unreliable conclusions
- Outliers disproportionately affecting averages (should medians be used instead?)
- Multiple testing / cherry-picking significant results
Aggregation errors:
- Double-counting from improper joins (many-to-many explosions)
- Incorrect denominators in rate calculations
- Mixing granularity levels (e.g., user-level metrics averaged with account-level)
- Revenue recognized vs. billed vs. collected confusion
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.

validate is a command published in the GitHub repository fergupa/claude_plugins (2 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 13 tokens to every session and 1,200 once invoked, about $0.0001 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 2026-08-31.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
