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 | $0.00128 | $0.01221 |
| Opus 5 | $0.00064 | $0.00611 |
| Sonnet 5 | $0.00026 | $0.00244 |
| Haiku 4.5 | $0.00013 | $0.00122 |
Grade C, and why
model scanned grade C 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 5d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Business Model — Lean Canvas & Unit Economics
Answer "how does this make money, and does the math survive contact with reality?" Two artifacts: the Lean Canvas (the whole model on one page) and the unit economics workbook (per-customer math + scenarios). All arithmetic shown, every input sourced or flagged as assumption.
Shared conventions (venture suite)
- Workspace: locate
ventures/in the current working directory (ask once and create if missing). All outputs go toventures/<slug>/<NN-module>/. - Templates are read-only. Files under a skill's
references/live inside the installed plugin and are shared by every venture. Never write to them. "Fill template X" always means: copy it intoventures/<slug>/<NN-module>/under a dated name and fill the copy. - Read
VENTURE.mdfirst. When done: update its Status table and append key findings to "Key facts & numbers" (format:- [module, YYYY-MM-DD] finding (source, confidence)). - Language: converse in the user's language. Write formal deliverables (reports, canvases, battlecards) in the
report_languageset in VENTURE.md. Persian reports keep standard English business terms as-is (TAM, SAM, SOM, CAC, LTV, GTM, churn, retention...). - Research integrity: cite every external claim (source + date). Mark every estimate with confidence (high/med/low). Never fabricate numbers — write "no data found" instead.
- Chain: end by updating VENTURE.md and suggesting the logical next module.
Workflow
1. Gather inputs — reuse before asking
Mine the workspace first: pricing & competitor price range (03-competitors, 05-gtm), market size & segment (02-market), willingness-to-pay evidence (01-discovery), churn/retention (04-pmf). Then ask the user only for what's missing: actual costs, current price, real CAC if any spend happened, capacity constraints (service businesses). Label every input: measured / sourced / assumption.
2. Lean Canvas
Copy references/lean-canvas.md to 06-model/lean-canvas-YYYY-MM-DD.md and fill the copy — pull problem/segment from discovery, UVP from positioning if GTM ran, revenue/cost lines from this module's math. Canvas cells cite their source module. Unknowns stay visibly TBD (a canvas full of guesses presented as facts is worse than gaps).
What ships with it
2 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.

model is a skill published in the GitHub repository heyparsadev/claude-venture-plugin (4 stars, last pushed 24d ago), licensed MIT. It adds 128 tokens to every session and 1,221 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
