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 | $0.00000 | $0.00402 |
| Opus 5.5 | $0.00000 | $0.00161 |
| Sonnet 5.5 | $0.00000 | $0.00080 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
metadata-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 1mo 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.
What it actually says
metadata-validator Skill
Validate ingestion package integrity, manifest schemas, and detect privileged content.
Capabilities
-
Manifest Validation (
scripts/validate-manifest.py)- Validates
manifest.yamlagainstmetadata-schema.yaml - Checks required fields, data types, enum values, patterns
- Usage:
python3 validate-manifest.py <manifest_path>
- Validates
-
Package Validation (
scripts/validate-package.py)- Checks complete ingestion package integrity
- Validates: normalized text, structural parse, manifest, clauses, numbering
- Applies hard-fail and soft-fail conditions
- Usage:
python3 validate-package.py <package_dir> - Exit codes: 0=valid, 1=hard fail, 2=soft fail
-
Privilege Leak Detection (
scripts/check-privilege-leak.py)- Scans for internal comments, attorney-client privilege markers, strategy notes
- Supports English and Korean patterns
- Usage:
python3 check-privilege-leak.py <file_or_dir> - Exit codes: 0=clean, 2=found but isolable, 3=found and cannot isolate
When to Use
- WF1 Step 8 (Validation & Risk Check): run all three validators
- Before publishing any asset to approved/
- When checking external-safe eligibility
Hard-Fail Conditions
These cause QUARANTINE:
- Normalized text is absent or empty
- Structural parse output is missing
- Three or more required manifest fields are missing
- Privileged content detected and cannot be isolated
- Source file is corrupt or unreadable
Soft-Fail Conditions
These cause STAGING (human review):
- Unmapped clauses ≥ 30%
- Defined term extraction failed
- Governing law is ambiguous
- Near-duplicate conflict unresolved
- Freshness-sensitive clause lacks

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.

metadata-validator is a skill published in the GitHub repository lowtidebuild/contract-review (41 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 402 tokens. 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.
