Example prompts

  • “Use the signals-scout-feature-flags skill to signal scout for PostHog feature flags. An agent skill from PostHog/posthog”
  • “/signals-scout-feature-flags”

Requirements

  • Compatibility (from SKILL.md): PostHog Signals agent (Claude sandbox). Read-only analytics + signal_scout_internal:write (scratchpad) + signal_scout_report:write (report channel), plus the feature-flag and analytics tools in the MCP tools section.

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Traffic contradictions — a healthy flag's evaluation volume falling off a cliff (the code call was removed or an SDK path broke), code…
  2. Flag debt — the flags a weekly server-side health check has already classified as cleanup candidates (you re-verify each one and give it…

What it can do on your machine

Read from SKILL.md and the folder at commit c012c8d. 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

    Shell commands in SKILL.md call:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    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.

  • Compatibility

    PostHog Signals agent (Claude sandbox). Read-only analytics + signal_scout_internal:write (scratchpad) + signal_scout_report:write (report channel), plus the feature-flag and analytics tools in the MCP tools section.

    From compatibility in the SKILL.md frontmatter.

Context cost

Signals Scout Feature Flags loads about 14k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 7,186 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~14k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 7,186 words (~13,589 tokens).

“You are a focused feature flags scout. A flag's configuration is a promise about what code paths users get — "this flag is serving", "this rollout is 25%", "this variant split is live" — and your job is to catch…”
