  • Find the aha moment

What it does

Diagnose Activation is an agent skill from amplitude/builder-skills. Diagnose where new users fail to activate, identify the aha moment, measure time-to-value, and build a sized plan to move activation rate. Use when a PM needs to understand why signups don't convert to active users, find the aha moment, reduce time-to-value, or improve onboarding.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Open-source AI skills for product managers — battle-tested by PMs at Amplitude.

When your agent uses it

  • A PM needs to understand why signups dont convert to active users
  • Find the aha moment
  • Reduce time-to-value
  • Improve onboarding

Example prompts

  • “/diagnose-activation”

What it can do on your machine

Read from SKILL.md and the folder at commit 51838c2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Diagnose Activation loads about 1.8k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 187 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 187 words (~1,797 tokens).

“Find where new users fall off, identify the aha moment that separates retained users from churned ones, and build a sized plan to move activation rate.”
