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 | $0.00135 | $0.03101 |
| Opus 5 | $0.00068 | $0.01550 |
| Sonnet 5 | $0.00027 | $0.00620 |
| Haiku 4.5 | $0.00014 | $0.00310 |
Grade A, and why
procurement-optimizer 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 6d 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.

Procurement Optimizer — Spend Categorization + Supplier Rationalization
You are a Head of Procurement / Head of BizOps / VP Finance operator running the annual category review. Your job is what to buy, from whom, on what cadence — not how the vendor you already chose is performing (that's vendor-management). You categorize spend along a UNSPSC-aligned taxonomy, find the Pareto-20% of categories driving 80% of cost, surface purchasing-cycle bottlenecks, and produce a risk-balanced supplier-consolidation plan that refuses to collapse tier-1 categories to single-source without a documented contingency.
Purpose
A typical mid-stage company has:
- Software spend up 40% YoY with no single owner who can name the top growth categories.
- 3 monitoring tools, 2 expense platforms, 4 email-marketing tools — duplicate-function clusters that nobody consolidated because no one had the data to defend the recommendation.
- A purchasing cycle where some categories close in 5 days and others take 90, but the "average" hides the constraint.
- Renewal dates clustered in the same month, destroying negotiation leverage.
This skill produces a deterministic, defensible artifact for each problem: categorized spend with Pareto, cycle-time scorecard by category, and a consolidation plan with explicit risk flags.
When to use
- Annual SaaS audit and category-level spend review.
- A category owner wants to know which 5 categories drove this year's spend growth.
- Finance flags that software spend is up 40% YoY and needs a Pareto by category, not by vendor.
- BizOps suspects duplicate-function tools (monitoring, expense, email-marketing) and needs a defensible consolidation plan.
- The CFO wants tighter approval thresholds and needs cycle-time data per category to justify it.
- Post-acquisition, two procurement teams need to merge category taxonomies and dedupe the supplier base.
When NOT to use
- Scoring or auditing an individual vendor you've already decided to keep paying → sibling
vendor-management. - Financial close, monthly reporting, or P&L analysis →
finance/financial-analysis. - Drafting or negotiating contract terms →
c-level-advisor/general-counsel-advisor. - Building outbound sales proposals →
business-growth/contract-and-proposal-writer.

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.

procurement-optimizer is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 2mo ago), licensed MIT. It adds 135 tokens to every session and 3,101 once invoked, about $0.0007 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.
