turritopsis-human-facing-pwa is a skill for Codex from anhe2021212-spec/Turritopsis. It costs 81 tokens per session (265 once invoked), scanned A, original, MIT.

A guide for designing and checking progressive web apps (PWAs)—web apps that can behave like installed apps—for people using an agent or service.

In plain words
What is it for?
Use it to plan user interactions, offline and retry behavior, sign-in and privacy rules, service-worker updates, responsive layouts, and deployment checks.
Why use it?
It helps prevent confusing differences between server data, browser state, cached data, and what the screen shows, including when a connection fails or a request is repeated.

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.

Security

Grade A, and why

turritopsis-human-facing-pwa 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.

What it actually says

Turritopsis Human-facing PWA

Map the PWA as a real product surface, not a decorative dashboard.

  1. Use $turritopsis-onboarding for local scanning and skeleton application.
  2. Read stage-suite.md.
  3. Choose Stages around human tasks and complete interaction paths, not component directories.
  4. Identify the authority for each visible value. Separate backend truth, client state, cache, and rendered presentation.
  5. Record offline, retry, duplicate-submit, authentication, privacy, update, and rollback semantics.
  6. Treat service-worker and asset versions as route-specific operational evidence, not proof that every client updated.
  7. Verify real installed and browser behavior at supported viewports; source inspection alone is insufficient.
  8. Use fixture.json as a quality example, not a template.
Files

What ships with it

3 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.

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.
