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 | $0.00037 | $0.02237 |
| Opus 5 | $0.00018 | $0.01118 |
| Sonnet 5 | $0.00007 | $0.00447 |
| Haiku 4.5 | $0.00004 | $0.00224 |
Grade A, and why
growth-loop-design 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 12d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Growth Loops & Network Effects
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:
- Referral Program Design
- Incentive System Design
- Marketplace Growth Strategy
- Network Effects Strategy
Determine whether a qualified output from one cycle creates a qualified input for a later cycle, where that mechanism weakens, and what evidence or design should come next. Do not call a funnel a loop because it is drawn as a circle, or treat gross sharing, revenue, content, or invitations as proof of retained growth.
Read loop-contract.md before mapping entities, value, evidence, identity, windows, economics, permissions, or a verdict. Read analysis-methods.md before calculating transitions, yield, cycle time, retained quality, saturation, or economics. Read diagnosis-and-design.md before naming a constraint or proposing a mechanism. Use playbook-sources.md to cite the pinned Growth Playbook basis.
Select One Mode
| Mode | Use |
|---|---|
audit |
Determine whether an existing mechanism closes and identify its most decision-relevant weak transition |
design |
Define a new loop hypothesis after customer or system value, retained value, and the next useful input are explicit |
measurement |
Specify entities, events, cohorts, identity, windows, quality, economics, and instrumentation needed to evaluate a loop |
What ships with it
29 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.
- 12d ago First seen · 115 lines · 37 tokens per session scan A 6706d6d2e39a
growth-loop-design is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 15d ago), licensed MIT. It adds 37 tokens to every session and 2,237 once invoked, about $0.0002 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 2026-08-30.
