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 | $0.00227 | $0.03168 |
| Opus 5.5 | $0.00091 | $0.01267 |
| Sonnet 5.5 | $0.00045 | $0.00634 |
| Haiku 4.5 | $0.00023 | $0.00317 |
Grade A, and why
find-cybersecurity-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.
Any HTTP client works (curl, fetch, requests). Examples below use curl. How it starts
The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
find-cybersecurity-firm
Drive the ServiceGraph API (https://api.servicegraph.co) to find,
shortlist, and enrich US cybersecurity firms via the pro_services
dataset.
Always pin service_provided:cybersecurity — that's the only
relevant structured tag in the live catalog. Older docs and the
catalog source mention sub-tags like pen-testing and
security-audit, but in the current release none of those exist as
separate tags — cybersecurity is the broad catch-all and every
sub-type (pen-testing, red-team, vCISO, SOC 2 readiness, IR retainer,
IAM, cloud security, AppSec) is a keyword substring search on firm
text. Confirm via /v1/datasets/pro_services/fields?include_values=1
once per session.
The industry tag also drifts between releases — newer catalogs may
use industry:cybersecurity, older ones used industry:security.
Confirm the value via /fields and pin both industry and
service_provided:cybersecurity for safety.

When NOT to use this skill
- Consumer/personal cybersecurity ("my Gmail got hacked", "how do I secure my home wifi") — the catalog is B2B procurement only.
- In-house security hires (Security Engineer, CISO, SOC analyst).
- DIY/configuration questions ("how do I patch CVE-X", "configure firewall rules", "review this Terraform").
- Security-product comparisons (CrowdStrike vs SentinelOne, EDR vendors, SIEM vendors).
- Generic security knowledge ("explain zero-trust", "what is OWASP Top 10").
- Non-US firms / individual freelance pen-testers / bug-bounty hunters.
MCP server (preferred for authed calls)
If your harness has the ServiceGraph MCP server loaded (tools
containing servicegraph), prefer those — OAuth 2.1 + PKCE keeps the
token in the harness sandbox. Otherwise use the REST flow below.
API surface (dataset id: pro_services)
Every endpoint requires the bearer (Authorization: Bearer vk_…).
No anonymous tier.
| Endpoint | Cost | Use it for |

GET /v1/datasets/pro_services/fields[?include_values=1] |
free | Confirm industry value name and cybersecurity is in service_provided. |
GET /v1/datasets/pro_services/check?filter=… |
free | Validate filter. |
POST /v1/datasets/pro_services/translate-intent |
free | {intent} → DSL filter + sanity count. |
GET /v1/datasets/pro_services/search?filter=…&limit= |
free | Brief firm cards + per-row unlock hint + total. |
GET /v1/datasets/pro_services/:apex |
free | One row brief; detail only if unlocked. |
POST /v1/datasets/pro_services/unlocks |
10 credits / firm | {apexes:[...]} ≤100; atomic; 30-day TTL on detail. |
GET /v1/me/credits |
free | Balance. |
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-cybersecurity-firm is a skill published in the GitHub repository nostrband/ServiceGraph (61 stars, last pushed 5mo ago), licensed MIT. It adds 227 tokens to every session and 3,168 once invoked, about $0.0009 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.
