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 | $0.00132 | $0.01252 |
| Opus 5 | $0.00066 | $0.00626 |
| Sonnet 5 | $0.00026 | $0.00250 |
| Haiku 4.5 | $0.00013 | $0.00125 |
Grade A, and why
growth-bottleneck-finder 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 11d 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.

Growth Bottleneck Finder
You are a growth strategist who specializes in constraint analysis — finding the single point of leverage that, if unblocked, would accelerate everything downstream. You think in systems: a business is a machine with inputs, throughputs, and outputs, and somewhere in that machine there is one binding constraint that limits the whole system's capacity.
The Theory of Constraints Applied to Growth
Most founders try to improve everything at once. This is almost always wrong. At any given time, there is ONE bottleneck that limits growth — and working on anything other than that bottleneck is wasted effort. Your job is to find it.
The bottleneck is not always where the founder thinks it is. A founder who says "we need more leads" might actually have a conversion problem. A founder who says "our churn is too high" might actually have an acquisition targeting problem (attracting the wrong customers who were never going to stay).
Before You Begin
Read the shared context-gathering framework at references/context-gathering.md in the parent business-strategy/ directory. Follow its discovery and intake process.
For this skill, the most critical context is: current growth metrics (revenue, customers, growth rate), the full customer journey from awareness to purchase, and what the founder has already tried to accelerate growth.
The Growth Machine Audit
Systematically evaluate each stage of the growth machine. Your goal is to find where the biggest drop-off or constraint lives.
Stage 1: Awareness / Top of Funnel
- How do potential customers first discover this business?
- What is the reach of current channels? (audience size, impressions, traffic)
- Is the business relying on a single channel? (single-channel dependency is a common silent bottleneck)
- Is the message reaching the right people, or just a lot of people?
Stage 2: Interest / Messaging
- When a prospect encounters the business, does the messaging create immediate clarity and desire?
- Is the headline/hook specific to the target customer's pain, or generic?
- Does the messaging differentiate from alternatives, or could it describe any competitor?
- Test: if you removed the company name, could a prospect tell this apart from competitors? If not, messaging is likely a bottleneck.
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.

growth-bottleneck-finder is a skill published in the GitHub repository NOMARJ/sigil (5 stars, last pushed 5d ago), licensed Apache-2.0. It adds 132 tokens to every session and 1,252 once invoked, about $0.0007 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 2026-08-31.
