headcount is an organization of independently installable Claude Code plugins, each grouping skills for a department such as finance, security, or demand generation. Claude Code users install the departments they need and invoke their skills for specialized work; the catalogue entries are skills and related agent tooling from that organization.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.00612 |
| Opus 5 | $0.00032 | $0.00306 |
| Sonnet 5 | $0.00013 | $0.00122 |
| Haiku 4.5 | $0.00006 | $0.00061 |
Grade A, and why
service-level-management 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Service level management
A service level is a promise with a number attached. The number is the easy part; choosing what to measure is where these go wrong.
Measure what the customer feels
The characteristic failure is a service meeting every target while customers are angry. It happens when the measure is chosen for availability of data rather than relevance:
- Uptime that excludes degraded operation. Technically up and unusably slow is down.
- Response time instead of resolution time. An instant acknowledgment that resolves nothing measures the autoresponder.
- Averages instead of percentiles. A mean hides the tail, and the tail is who complains. Commit at p95 or p99, not the mean.
- Measurement from inside your own perimeter, which excludes the part of the path the customer actually traverses.
Set targets you would fund
A target is a spending decision. Each added nine costs disproportionately more than the last, so the question is never "what would be good?" but "what is the gap worth to the customer, and does it exceed what closing it costs?"
Set the internal objective tighter than the external commitment. The gap between them is your warning margin; without it, the first thing you learn about a breach is the breach.
Write them so both sides can tell
An unmeasurable clause is a future dispute. Every service level needs: what is measured, where it is measured from, how it is calculated, what is excluded, over what window, and what happens when it is missed.
Exclusions are the substance — planned maintenance, force majeure, customer-caused failures,
dependencies outside your control. Vague exclusions get read narrowly when it matters. For anything
with contractual teeth, legal-risk:contract-review owns the remedy language; this skill owns
whether the number is achievable.
When you breach
Say so before the customer does. A breach reported by the provider with a cause and a fix costs far less trust than one the customer discovers and raises.
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.

service-level-management is a skill published in the GitHub repository cbrock84/headcount (1,300 stars, last pushed 5d ago), licensed MIT. It adds 65 tokens to every session and 612 once invoked, about $0.0003 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.
