What it does
Product Library is an agent skill from AlpacaLabsLLC/skills-for-architects. Inspect or save reusable FF&E library products through reviewed, guarded transactions. Use for explicit library imports, corrections or recovery; adopted selections and workbook reconciliation belong to master-schedule.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `README.md`, `host-contract.json` and `scripts/csv-library.py`).
It sits in Business, Finance & HR, covering Accounting and bookkeeping. The repository describes itself as: Claude Code skills for architecture, real estate, and workplace strategy. Type /skill-name and go. The licence is MIT.
When your agent uses it
- Explicit library imports
- Adopted selections and workbook reconciliation belong to master-schedule
Example prompts
- “/product-library”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Bash, AskUserQuestion
What it can do on your machine
Read from SKILL.md and the folder at commit 657bfd5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteBashAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Product Library loads about 1.3k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 551 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

allowed-tools: Read, Write, Bash, AskUserQuestion
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

/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.
<!-- architecture-studio:harness-compatibility -->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.

Before changing records
Follow the native mutation sequence: Inspect → Prepare → Verify preparation → Apply → Verify result → Complete. Inspect pending work first. Retain the complete original/absence and complete prepared product CSV, actual access metadata, import-source guards and bound intent. Finish durable saving and independently reopen every retained file before the first publisher; writing evidence without rereading it is insufficient. Validate the entire actual prepared CSV. Publish only under actual writer protection with fresh byte/access guards. Mark complete only after actual library bytes, schema, selected changes and preserved data read back.
Use stable request IDs and the exact preview hash under the library binding/retry rules.
A stale preview or reused ID with changed inputs is a conflict, not permission to substitute a new
hash. Empty update changes are a byte-preserving no-op after unique-match validation. Exact repeated
append requests return their verified prior result; a new intentional append has a new operation ID.
product_library.recover inspects retained evidence and actual state, continuing only a proven safe
before/after state. Preserve third-state conflicts, pending work, old logs and unpublished crash evidence.
Historical evidence paths are readable records, not a dependency on the old helper or its locks.
Report the observed result
Return target, request ID, before/after/current hashes and readback-supported outcome, with any
pending recovery reference. An old completed operation may have current_matches_result: false
after later edits; report that difference and preserve current state. Never describe a preview,
receipt alone or delivered instructions as a completed save. Use the completion contract.
For a requested registered authored report, use receive-owned native documents.resolve/register/query
with confirmed coordinates and its complete document/register publication set. One-off derived files
need no registration. No report or library save authorizes adopted schedule, project-fact or EPD changes.

Can I use Product Library in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add AlpacaLabsLLC/skills-for-architects --skill product-library -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/product-library, .gemini/skills/product-library, .github/skills/product-library and .opencode/skills/product-library in your project.
What does Product Library need to run?
Going by SKILL.md and its folder, Product Library needs Python for the scripts in its folder. Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Bash, AskUserQuestion.
Does Product Library access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Product Library safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Product Library use?
Product Library is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Product Library use?
About 1.3k tokens (SKILL.md is roughly 5.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
