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

inventory-check 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 2mo ago.

The scan reads SKILL.md. This mod also ships 4 executable files (__init__.py, __main__.py, main.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.

What it actually says

Inventory Check

Reads beer.md, spirits.md, and wine.md from the inventory directory. Compares each item's quantity against its reorder threshold. Reports items at or below threshold.

Read-only. Does not modify files or reach external services. No PII in output.

When to Use

  • Daily morning check before opening (scheduled: 10:00 AM)
  • Before placing vendor orders (Sunday/Monday)
  • When a bartender reports running low on something
  • After receiving a delivery, to confirm stock levels updated

Procedure

Run the skill from the repo root:

# Human-readable summary
python -m skills.inventory_check

# Structured JSON output (for automation)
python -m skills.inventory_check --format json

# Against a custom inventory directory
python -m skills.inventory_check --inventory-dir path/to/inventory --format json

Parse the JSON result:

  • status: "ok" (nothing to reorder) or "warn" (items need attention)
  • findings: array of LOW_STOCK items with category, item name, qty, reorder_at
  • data.items_scanned: total items checked
  • data.low_stock: detailed list of low items

Exit Codes

Code Meaning
0 All stock levels acceptable
1 One or more items at or below reorder threshold
2 Config error (bad arguments)
3 Data error (can't read inventory files)
10 Unexpected error

Verification

After running, confirm:

  • Exit code is 0 or 1 (not 2, 3, or 10)
  • stdout is valid JSON (when using --format json)
  • data.items_scanned > 0 (files were actually read)
  • If exit code is 1, findings array is non-empty
Files

What ships with it

13 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.

Changes

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.
