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 | $0.00026 | $0.04042 |
| Opus 5 | $0.00013 | $0.02021 |
| Sonnet 5 | $0.00005 | $0.00808 |
| Haiku 4.5 | $0.00003 | $0.00404 |
Grade A, and why
validation-coordinator 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 5d 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 — 506 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
The validation-coordinator skill provides structured methods for managing sequential validation specialist invocation, tracking validation workflow progress, and ensuring all quality gates are satisfied before deployment. It handles specialist dependencies, failure tracking, and overall validation status reporting.
When to Use
This skill auto-activates when you:
- Coordinate sequential validation specialists (5-6 specialists)
- Manage validation workflow across test writing, test execution, quality checks, and security scans
- Track validation progress and status
- Ensure specialist dependencies are satisfied (e.g., tests written before execution)
- Monitor validation failures and re-validation cycles
- Generate comprehensive validation status reports
- Prepare validation results for deployment phase
Provided Capabilities
1. Sequential Specialist Invocation
- Specialist Ordering: Invoke specialists in correct sequence with dependencies
- Prerequisite Validation: Ensure each specialist's inputs are ready before invocation
- Invocation Tracking: Log each specialist invocation with timestamp
- Status Monitoring: Track specialist status (pending, in-progress, completed, failed)
2. Validation Workflow Management
- Phase Tracking: Monitor validation phases (test writing, test execution, quality, security)
- Dependency Resolution: Ensure specialists run in order (unit tests → integration tests → test execution)
- Workflow Visualization: Provide clear view of validation progress
- Completion Detection: Identify when all validations complete
3. Failure Tracking
- Failure Logging: Record all validation failures with details
- Iteration Tracking: Count re-validation attempts per specialist
- Failure Analysis: Identify patterns in validation failures
- Escalation Detection: Flag specialists exceeding max iterations
4. Overall Validation Status
- Aggregate Status: Compute overall validation status (in-progress, passed, failed)
- Quality Gate Tracking: Monitor each quality gate (tests, coverage, quality, security)
- Pass/Fail Reporting: Report which validations passed/failed
- Readiness Assessment: Determine if feature is ready for deployment
What ships with it
2 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.

validation-coordinator is a skill published in the GitHub repository matteocervelli/llms (25 stars, last pushed 3mo ago), licensed MIT. It adds 26 tokens to every session and 4,042 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 2026-09-03.
