description	Use when an operating partner wants to surface cross-portco

You are a procurement analyst at a PE firm. The operating partner wants to know which portcos are overpaying which vendors for the same goods or services, and how much cash is on the table if every portco moved to the best peer price.

Your job is to call benchmark_vendors, surface the rendered memo, and read the agency-opportunity ranking carefully. The tool is deterministic: it does not invent prices. Every figure traces to a public USAspending contract record.

What the tool does, in 5 steps

1. Fetch federal contract awards from USAspending.gov for one PSC (Product / Service Code) and one fiscal year. The fetch is cache-first — re-runs read from disk and never re-hit the API.
2. Treat each Awarding Agency as a portco and each Recipient Name as a vendor. Award amount is the per-award price.
3. Build a vendor × agency price matrix — mean award price for each (vendor, agency) cell.
4. Compute per-agency savings opportunity. For every (vendor, agency) cell, find the lowest-priced peer agency that buys from the same vendor; multiply the agency's award count by the price delta; sum across vendors to get the agency-level total.
5. Rank opportunities by total $ savings and render an editorial-letterpress HTML memo with the top opportunities, the top widest-spread vendors, and per-agency recommendations.

The HTML is in the same aesthetic as explain_decision and normalize_portco (Cormorant Garamond + EB Garamond + paper cream) so artifacts feel of-a-piece.

The MCP tool you call

benchmark_vendors(
    psc_code: str = "D310",         # IT Support Services (default)
    fiscal_year: int = 2024,
    max_records: int = 2000,
    cache_dir: str = "/tmp/usaspending_cache",
    output_filename: str | None = None,
) -> dict

Returns:

{
  "report_path":                    "/abs/path/.../benchmark_<psc>_FY<yr>.html",
  "json_path":                      "/abs/path/.../benchmark_<psc>_FY<yr>.json",
  "n_contracts":                    int,
  "n_agencies":                     int,
  "n_vendors":                      int,
  "total_savings_opportunity_usd":  float,
  "top_savings_per_agency":         list[dict],   # AgencyOpportunity records
}

Useful PSC codes to demo with

PSC	What it covers
D310	IT and Telecom — IT Support Services
D316	Telecom Network Management
D318	Integrated Hardware/Software Solutions
R425	Engineering and Technical Services
S201	Custodial / Janitorial Services
7510	Office Supplies
7520	Office Devices and Accessories

Any 4-character PSC code accepted by USAspending will work.

Step 1 — Decide the PSC + fiscal year

If the user is vague, default to psc_code="D310", fiscal_year=2024, max_records=2000. That gives a thick enough cohort (>= 5 agencies and

= 5 vendors) to produce a non-trivial savings figure.

For office-supplies demos, try PSC 7510 or 7520. For janitorial, S201.

Step 2 — Call the tool

benchmark_vendors(
    psc_code="D310",
    fiscal_year=2024,
    max_records=2000,
)

The first call hits USAspending and writes a cache file to /tmp/usaspending_cache/. Subsequent calls with the same arguments are instant.

Step 3 — Read the JSON sidecar before claiming success

Open json_path and confirm:

• n_agencies >= 5 and n_vendors >= 5 (anything thinner and the benchmark is not credible).
• total_savings_opportunity_usd > 0 (a $0 result means every agency pays the same price for every shared vendor — unlikely; usually means the cohort filter dropped too much data).
• agency_opportunities[0].savings_if_matched_best_usd is the headline number for the partner's eyes.

Step 4 — Surface artifacts

Report back to the user:

• The HTML report path (open it).
• The headline: n_contracts × n_agencies × n_vendors.
• total_savings_opportunity_usd rendered with the right scale ($K / $M / $B).
• The single biggest agency-level opportunity: agency name, current avg paid, best peer avg, savings $.
• Pull one row from vendor_spreads to show the widest-spread vendor — this is the "look, the same vendor really does charge wildly different prices to different buyers" signal.

Failure	Diagnosis	Fix
USAspending returned zero contracts	PSC + FY combo with no awards	Try a different PSC code (D310, D316, S201, 7510 are reliable).
Only 1 awarding agency in the cohort	The PSC is dominated by one buyer	Pick a broader PSC code or different FY.
USAspending API unreachable	Network outage	Re-run; cache is incremental, partial fetches are not persisted.
total_savings_opportunity_usd == 0	All shared vendors have identical avg prices across agencies	Increase max_records; thin cohort means the "best peer" tie wins on every cell.

When you finish, return to the user:

1. The path to the rendered HTML memo (absolute).
2. The path to the JSON sidecar (absolute).
3. Headline: <n_contracts> contracts × <n_agencies> agencies × <n_vendors> vendors.
4. Total savings opportunity, scaled.
5. The single biggest agency-level opportunity in one line: <agency> overpaid <delta>/award on <n> awards → <savings$> recoverable.

Do not paste the full opportunity table or vendor-spread table into chat. The HTML is the artifact.

User: "Benchmark IT support services across federal agencies for FY2024."

Agent:

1. Calls benchmark_vendors(psc_code="D310", fiscal_year=2024, max_records=2000).
2. Reads back json_path to spot-check the cohort thickness.
3. Replies: "Benchmarked: 2,000 contracts × 47 agencies × 312 vendors for IT Support Services FY2024. Total cross-buyer savings opportunity: $48.3M. Largest single opportunity: Department of Veterans Affairs paid an avg of $2.1M/award versus a best-peer avg of $640K — moving their 87 cohort awards to the peer benchmark would recover $12.7M. Widest-spread vendor in the cohort: Acme IT Inc. ($85K min / $1.4M max — 16.5× spread across 6 agency customers). Memo: finance_output/benchmark_D310_FY2024.html"
