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 | $0.00053 | $0.00232 |
| Opus 5 | $0.00026 | $0.00116 |
| Sonnet 5 | $0.00011 | $0.00046 |
| Haiku 4.5 | $0.00005 | $0.00023 |
Grade A, and why
bom-schema 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 3d 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
BOM Schema Skill
Define and validate bill-of-materials schemas with stable field names and predictable resource identifiers.
Templates in This Skill
| Template | Purpose |
|---|---|
bom-schema-template.json |
JSON Schema starter for BOM validation rules, required fields, and naming constraints |
Core Rules
- Validate required fields before downstream processing.
- Keep resource identifiers in a single documented format.
- Enforce naming conventions consistently across every row or item.
- Prefer explicit schema rules over free-form notes.
Agent Pairing
Use with agents that ingest BOMs, validate structured inventory data, or generate machine-readable contract files.
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.

bom-schema is a skill published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed 2d ago), licensed MIT. It adds 53 tokens to every session and 232 once invoked, about $0.0003 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.
