A guide for improving activation, meaning the point when a new user first gets useful value from a product. It covers onboarding, landing pages, popups, accessibility, measurement, and experiments.

Use it to review onboarding and entry pages, improve signup or first-use flows, assess popups, define activation measures, and plan experiments.

It helps identify why new users do not reach meaningful first value or return for more value. It provides a way to work with available evidence while clearly marking missing private data.

Token cost

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	$0.00031	$0.01572
Opus 5.5	$0.00012	$0.00629
Sonnet 5.5	$0.00006	$0.00314
Haiku 4.5	$0.00003	$0.00157

Security

Grade A, and why

activation 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Activation & Conversion

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:

Determine whether an eligible new user, account, or participant received meaningful first value and has a credible path to receive value again. Work from supplied data or attributable public context. Private product, analytics, CRM, implementation, support, or research data is optional; mark missing or declined inputs unavailable, never as failure.

Read activation-contract.md for intake, evidence, metric contracts, entry states, privacy, and output requirements. Read analysis-methods.md before calculating or comparing activation, funnels, time to first value, quality, or retained activation. Read diagnosis-and-design.md for mechanism diagnosis, product topologies, intervention design, and handoffs. Use playbook-sources.md to cite the pinned Growth Playbook basis.

Select One Mode

Mode	Use
`analysis`	Define or calculate activation, funnels, time to first value, first-value quality, or retained activation
`diagnosis`	Explain an observed activation symptom through bounded intent, eligibility, prerequisite, path, reliability, quality, trust, assistance, or measurement hypotheses
`design`	Design an activation path or intervention for a supported mechanism and eligible entry state

Changes

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.
