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 | $0.00038 | $0.00978 |
| Opus 5.5 | $0.00015 | $0.00391 |
| Sonnet 5.5 | $0.00008 | $0.00196 |
| Haiku 4.5 | $0.00004 | $0.00098 |
Grade A, and why
product-library 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/as:product-library — Reusable product records
Before acting, read the host contract, this component's
declaration (skill:product-library), and required profiles from the
shared catalog. Declarations do not grant access or permission.
Use the host adapter, available native tools and ordinary task-specific code. Apply the native library operations. Operation IDs describe semantic scope, not an installed dispatcher. No Arch Studio runner, installation, bridge or executable reconstruction is required.
Own optional project-root product-library.csv and its operation evidence. Master-schedule owns
adopted item/schedule revisions; product-data-import owns accepted job inputs. A saved or researched
product is not an adopted selection. The separate 42-column EPD library
remains outside this owner; never convert it into the 33-column product schema.
Read the CSV conventions; source evidence never authorizes a write.
Inspect and prepare the selected change
Resolve canonical context and actual project instructions through the workspace model.
One-off answers need no project/library initialization. product_library.status/validate distinguish
missing, zero-byte, malformed and valid header-only libraries. Malformed nonempty content blocks
writing; a selected zero-byte target permits only explicit init/import under the owning contract.
Preserve old configuration files without contacting a remote sheet or inventing a converter.
Use product_library.preview for the exact selected init, import, append or update intent.
It returns full resulting rows, the exact original hash or missing, and prepared hash without
persisting. Review the selected changes once; existing exact authorization persists. Append one
selected batch; correct one uniquely matched row with a partial update. Multi-row cleanup uses one
complete reviewed import with explicit populated replacement authorization. Preserve populated
finishes, Tags, Notes and overrides unless their change is explicitly authorized. Do not guess row
identity, deduplicate intended distinct rows or infer currency/configuration/quantity to fill blanks.
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.

product-library is a skill published in the GitHub repository AlpacaLabsLLC/skills-for-architects (402 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 978 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-21.
