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 | $0.00092 | $0.02520 |
| Opus 5.5 | $0.00037 | $0.01008 |
| Sonnet 5.5 | $0.00018 | $0.00504 |
| Haiku 4.5 | $0.00009 | $0.00252 |
Grade A, and why
marketplace-growth-strategy 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.

Marketplace Growth Strategy
Design marketplace growth around complete, valuable cross-side interactions inside a declared atomic market. Optimize reliable local liquidity, participant value, quality, trust, and contribution rather than users, listings, requests, transactions, GMV, subsidies, or geographic coverage alone.
Read marketplace-contract-and-evidence.md before accepting participant, market, supply, demand, interaction, or evidence claims. Read liquidity-matching-and-quality.md before measuring liquidity, diagnosing the hard side, or changing discovery and matching. Read cold-start-economics-and-expansion.md before seeding, subsidizing, monetizing, or replicating a market. Read governance-experiments-and-output.md before proposing ranking, experiments, trust controls, AI, or delivery. Use playbook-sources.md for the pinned Growth Playbook basis.
Select One Mode
| Mode | Use |
|---|---|
specification |
Private operating evidence or a stable market contract is absent |
audit |
Diagnose an existing liquidity, quality, retention, economic, or scale claim |
cold-start |
Select an atomic market, hard-side hypothesis, seeding path, and graduation gates |
optimization |
Improve one constrained transition in a functioning market without damaging another side |
replication |
Decide whether a working local market can expand, bridge, or transfer |
Name one primary mode, decision, owner, customer, participant sides, payer, product, atomic market, core interaction, horizon, and external-action boundary. If decision-critical evidence is missing, return an evidence-pending specification rather than inventing a score, threshold, forecast, or roadmap.
Freeze The Marketplace Contract
Record:
- customers, users, providers, suppliers, buyers, requesters, payers, beneficiaries, operators, and affected nonparticipants;
- atomic market boundary across geography, time, category, use case, service promise, product version, language, and legal entity;
- supply, inventory, availability, demand, request, candidate, offer, match, transaction, payment, fulfillment, quality, review, dispute, repeat, and exit entities;
- participant value before and after the core interaction, natural frequency, eligibility, identity, deduplication, state, window, and maturity;
- discovery, ranking, response, match, acceptance, completion, cancellation, failure, refund, dispute, off-platform, and recovery rules;
- side-specific acquisition, onboarding, utilization, retention, economics, incentives, concentration, multi-homing, and disintermediation;
- trust, safety, accessibility, privacy, security, moderation, payment, insurance, support, incident, appeal, and stop controls;
- source, owner, version, as-of, period, evidence state, contradiction, limitation, expiry, and requested external action.
What ships with it
5 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.

marketplace-growth-strategy is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 2mo ago), licensed MIT. It adds 92 tokens to every session and 2,520 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 2026-08-30.
