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 | $0.00209 | $0.03613 |
| Opus 5.5 | $0.00084 | $0.01445 |
| Sonnet 5.5 | $0.00042 | $0.00723 |
| Haiku 4.5 | $0.00021 | $0.00361 |
Grade A, and why
find-engineering-firm scanned grade A with 1 finding 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.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

find-engineering-firm
Drive the ServiceGraph API (https://api.servicegraph.co) to find,
shortlist, and enrich US real-world engineering firms — buildings,
infrastructure, energy, manufacturing — via the pro_services
dataset. The catalog tags firms with industry:engineering_services
and a ~23-tag service sub-taxonomy.
This is NOT for software engineering. "Software engineering firm", "engineering team", "engineering manager hire", "system architecture review" — those are all software-developer territory. The first thing this skill confirms is that the user means real engineering, not software.
Always pin industry:engineering_services. Note the _services
suffix — older docs sometimes show industry:engineering but the
literal pin returns zero results in the live catalog. Sub-disciplines
are typically structured service_provided tags
(civil-engineering, structural-engineering, mep-engineering,
etc.) — confirm exact names via
/v1/datasets/pro_services/fields?include_values=1. Surveying is
surveying-mapping, not surveying.

When NOT to use this skill
The dominant failure mode is firing on software-engineering asks. Refuse those.
- Software / SaaS / app-development asks — even when phrased as "software engineering firm", "engineering team partner", "build our platform" → defer to
find-software-developer. - In-house "engineering manager" hires — in modern B2B usage this is almost always software-engineering recruiting. Refuse.
- System / cloud / database architecture questions ("Postgres vs DynamoDB", "monolith vs microservices") — software topics.
- Architecture (buildings) —
find-architecture-firmcovers that industry (when it exists). This skill covers engineering disciplines that work with architects (structural, MEP, civil), but the architect-of-record procurement is a different fire. - Consumer/residential ("architect for a residential remodel", "engineer to inspect my house"). Catalog is B2B procurement only.
- Non-US firms / individual freelance engineers / DIY questions / engineering-software product comparisons (Revit, AutoCAD, SolidWorks, Ansys).
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.

find-engineering-firm is a skill published in the GitHub repository nostrband/ServiceGraph (61 stars, last pushed 5mo ago), licensed MIT. It adds 209 tokens to every session and 3,613 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
