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

chrome-webstore 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 today.

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

<quick_start>

  1. Identify whether the task is listing creation, listing review, field-spec lookup, or another Chrome Web Store request.
  2. Read references/listing-spec.yaml before quoting any field limit, required flag, or asset dimension.
  3. Route creation work to workflows/create-listing.md and review work to workflows/review-listing.md.
  4. Use references/search-optimization.md only when copy or discoverability guidance is needed.
  5. Use references/official-docs.md when the user challenges or asks to verify a spec. </quick_start>

<essential_principles>

How This Skill Works

Principle 1: Data-driven field specs

All character limits, asset dimensions, formats, and required/optional flags live in references/listing-spec.yaml. Read the YAML — never recite limits from memory. When Google updates the requirements, only the YAML changes.

Principle 2: Two listing surfaces, four dashboard tabs

A CWS submission has two deliverable groups: (1) listing content (text + images on the public store page) and (2) compliance metadata (privacy, distribution, test instructions). The dashboard splits these into four tabs — Store Listing, Privacy, Distribution, Test Instructions — all must be complete before "Submit for Review" is enabled.

Principle 3: Assets first, copy second

Image assets have hard pixel dimensions and a review pass of their own. Produce assets to spec before writing descriptions so copy can reference what's shown in screenshots.

Principle 4: Single purpose is the spine

Every field (title, summary, description, permissions justification, category) must reinforce one narrow purpose. Google rejects or delays extensions whose listing suggests multiple purposes. </essential_principles>

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.
