ct-skill-validator

ct-skill-validator is a skill for Claude Code, Codex from kryptobaseddev/cleo. It costs 93 tokens per session (2,384 once invoked), scanned A, original, MIT.

A validator for checking whether a skill folder follows the full CLEO standard. It runs structural, ecosystem, and quality checks and produces an HTML report.

In plain words
What is it for?
Use it to validate skill folders, inspect body quality, check manifests and dispatch settings, and prepare a report for release.
Why use it?
It catches format errors and ecosystem problems before a skill is distributed. Re-running the checks helps confirm that fixes worked.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ct-skill-validator 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.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/_skill_finder.py, scripts/audit_body.py, scripts/check_depth.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

CLEO Skill Validator

Full 3-phase validation loop for CLEO skills. Every phase must reach PASS before the skill is considered ecosystem-ready. Run the phases in order and iterate on failures.

Always end with the HTML report — the final deliverable to the user is the combined report opened in their browser, not terminal output.


Phase 1: Structural Compliance (Iterate to Zero Errors)

Run validate.py until the result is PASS or PASS (with warnings) with 0 errors. Warnings are acceptable; errors are not. Fix errors and re-run.

# Full gauntlet — text output
python ${CLAUDE_SKILL_DIR}/scripts/validate.py <skill-dir>

# With manifest checks (Tier 4):
python ${CLAUDE_SKILL_DIR}/scripts/validate.py <skill-dir> \
  --manifest <manifest.json> --dispatch-config <dispatch-config.json>

# JSON output (for scripting):
python ${CLAUDE_SKILL_DIR}/scripts/validate.py <skill-dir> --json

# Deep body quality audit (optional, run alongside validate.py):
python ${CLAUDE_SKILL_DIR}/scripts/audit_body.py <skill-dir>

# Manifest alignment check: bundled into validate.py Tier 4. Use:
#   python validate.py <skill-dir> --manifest <manifest.json> --dispatch-config <dispatch-config.json>

# Progressive-disclosure depth check (T9684 — CI gate):
python ${CLAUDE_SKILL_DIR}/scripts/check_depth.py <skill-dir>

# Repo-wide depth sweep:
python ${CLAUDE_SKILL_DIR}/scripts/check_depth.py <repo-root> --all

# Allowlist audit (CI / cron — exit 1 on findings):
python ${CLAUDE_SKILL_DIR}/scripts/check_depth.py <skill-dir> --audit-allowlist
python ${CLAUDE_SKILL_DIR}/scripts/check_depth.py <skill-dir> --audit-allowlist --json

Depth rule (T9684): A skill PASSES when ANY of:

  • SKILL.md body has ≥ 100 content lines, OR
  • references/ subdir has ≥ 3 markdown files, OR
  • manifest.json references[] array enumerates ≥ 3 files (all on disk)

Pre-existing stubs are allowlisted with follow-up task IDs in scripts/check_depth.py::ALLOWLIST. Gold-standard skills: ct-orchestrator (9 refs) and ct-skill-creator (7 refs).

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.
