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 | $0.00027 | $0.02832 |
| Opus 5.5 | $0.00011 | $0.01133 |
| Sonnet 5.5 | $0.00005 | $0.00566 |
| Haiku 4.5 | $0.00003 | $0.00283 |
Grade A, and why
market-sizing 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 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.
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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Market Intelligence & Sizing
Reuse Growth Context
At the start, read .agents/growth-context.md when it exists. Reuse only product, customer, market, outcome, constraint, evidence, and routing fields whose scope, definition, source, and date remain compatible; state what is reused and surface conflicts or staleness before asking for decision-changing gaps. The file grants no system access or execution authority, and this Skill must not silently rewrite the primary diagnosis.
Integrated Capabilities
This Skill consolidates adjacent workflows behind one trigger. Use the main workflow for core requests. When a request matches a module below, read that module before executing it:
Estimate a bounded demand and economic opportunity from explicit customer, job, geography, time, eligibility, frequency, value, serviceability, reachability, overlap, and evidence contracts. Treat TAM, SAM, and SOM as labels only after their definitions are frozen; a market size is a versioned decision model, not a fact that exists independently of units and assumptions.
Read market-contract.md before accepting population, customer, category, demand, price, spend, transaction, or share evidence. Read methods-and-reconciliation.md before using top-down, bottom-up, supply, transaction, value-pool, or observed-demand methods. Read uncertainty-and-scenarios.md before combining sources, returning ranges, estimating attainable share, comparing markets, or refreshing estimates. Read decisions-and-governance.md before connecting size to segments, positioning, price, entry, acquisition, forecasts, privacy, or market transfer. Read output-contract.md before delivery. Use playbook-sources.md to cite the pinned Growth Playbook basis.
What ships with it
15 files 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-sizing is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 2mo ago), licensed MIT. It adds 27 tokens to every session and 2,832 once invoked, about $0.0001 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 2026-08-30.
