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 | $0.00093 | $0.00975 |
| Opus 5.5 | $0.00037 | $0.00390 |
| Sonnet 5.5 | $0.00019 | $0.00195 |
| Haiku 4.5 | $0.00009 | $0.00097 |
Grade A, and why
market-entry 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 1mo 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Market entry
Entry decisions are usually made on the size of the opportunity and lost on the cost of serving it. The market was real; what was underestimated was everything required to operate there.
Size from the bottom up, then check it against the top down
A market report gives you a number that includes companies who will never buy from you. Build the estimate from countable things: how many organizations fit your profile, how many have the problem acutely, what they spend on it today, what share you could plausibly hold in a defined period.
Use a top-down figure only as a sanity check. If bottom-up and top-down differ by an order of magnitude, one of them contains an assumption nobody has stated, and finding it is the most valuable hour in the analysis.
Test whether the advantage actually transfers
The question is not whether the market is attractive — attractive markets are attractive to everyone, including incumbents already there. The question is what you have that wins.
Advantages transfer unevenly. Product capability usually transfers. Brand rarely does across geographies. Distribution and relationships almost never do. Cost structure may invert entirely. An entry justified by "we are strong in the adjacent market" needs to name the specific thing that carries over, and it is usually less than assumed.
Ask why the incumbent has not already done what you plan to do. Either they cannot, which is your advantage, or they have found it does not work, which is your warning.
Choose the entry mode against speed, control and reversibility
- Organic — full control, slowest, and every local capability has to be built. Right when the advantage is the product and the market is reachable with your existing motion.
- Partnership or distribution — fast and cheap, and you learn less. Right when local relationships are the barrier and you can accept less control of the customer relationship.
- Acquisition — buys presence and capability immediately, at the highest price and with the integration risk. Right when time matters more than money and the target has something you cannot build quickly.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

market-entry is a skill published in the GitHub repository cbrock84/headcount (2,077 stars, last pushed 2d ago), licensed MIT. It adds 93 tokens to every session and 975 once invoked, about $0.0004 per session on Opus 5.5. 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.
Other skills, from other repositories
launch-google-search
Launch a complete Google Ads Search campaign — campaign, ad group, responsive search ads, keywords, sitelinks, callouts, and negatives — built paused and ready to review. Use when the user wants to spin up a new Search campaign on Google Ads.
negative-keyword-sweep
Find wasted spend in Google Ads search terms and add negatives at the right scope (account list, campaign, or ad group). Use when the user says "find junk keywords", "stop wasting on bad searches", or wants a search-terms cleanup.
rotate-creative
Pause fatigued ads and ship fresh creative variants in their place. Works on both Meta and Google Ads. Use when CTR is dropping, frequency is climbing, or the user says "creative is tired" / "let's refresh ads". Always starts new variants paused.
go
Compatibility entry for Visual Stack's former /vstack:go command. Runs the wireframe and UI review tool, now called review. Use only when the user invokes /vstack:go.
save
Save durable decisions, findings, plans, and implementation knowledge from the visible Codex conversation into a new or existing NeatContext context. Use only when the user explicitly invokes this skill or asks to preserve the current conversation as reusable context.
dns
This skill should be used when the user asks about "DNS", "domain resolution", "GeoDNS / geo routing", "latency-based routing", "weighted / failover routing", "Route 53 / Cloud DNS", an "A/CNAME/ALIAS record", "anycast", or "DNS TTL / propagation". It gives the global front door that maps a name to the right IP and…
