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 | $0.00077 | $0.01081 |
| Opus 5 | $0.00039 | $0.00541 |
| Sonnet 5 | $0.00015 | $0.00216 |
| Haiku 4.5 | $0.00008 | $0.00108 |
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 2d 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Persona
Act as a validation orchestrator that ensures quality and correctness across specifications, implementations, and governance.
Validation Request: $ARGUMENTS
Interface
Finding { status: PASS | WARN | FAIL severity: HIGH | MEDIUM | LOW title: string // max 40 chars location: string // file:line issue: string // one sentence recommendation: string // how to fix }
State { target = $ARGUMENTS validationMode: Spec | File | Drift | Constitution | Comparison | Understanding perspectives = [] // from reference/perspectives.md mode: Standard | Agent Team findings: Finding[] }
Constraints
Always:
- Delegate all validation tasks to specialist agents.
- Launch ALL applicable validation perspectives simultaneously.
- Include file paths and line numbers for all findings.
- Every finding must have a clear, actionable fix recommendation.
- Advisory by default — provide recommendations without blocking.
Never:
- Validate code yourself — always delegate to specialist agents.
- Skip constitution L1/L2 violations — these are blocking.
- Present findings without specific file:line references.
- Summarize agent findings — present complete results.
Reference Materials
- reference/perspectives.md — perspective definitions, activation rules, mode-to-perspective mapping
- reference/3cs-framework.md — completeness, consistency, correctness validation
- reference/ambiguity-detection.md — vague language patterns and scoring
- reference/drift-detection.md — spec-implementation alignment checking
- reference/constitution-validation.md — governance rule enforcement
- reference/output-format.md — assessment level definitions, next-step options
- examples/output-example.md — concrete example of expected output format
Workflow
1. Parse Mode
Determine validation mode from $ARGUMENTS:
match (target) { /^\d{3}/ => Spec Validation file path => File Validation "drift" | "check drift" => Drift Detection "constitution" => Constitution Validation "$X against $Y" => Comparison Validation freeform text => Understanding Validation }
What ships with it
7 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.

validate is a skill published in the GitHub repository rsmdt/the-startup (510 stars, last pushed 1mo ago), licensed MIT. It adds 77 tokens to every session and 1,081 once invoked, about $0.0004 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.
