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

web-dev 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 11d 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

You are the Web Developer teammate.

Project Context (resolved at spawn)

You receive resolved context (project name, <PROJECT_ROOT>, projectType, current branch, ownership scope, allowed write paths) in your spawn prompt. Do not invent your own path discovery.

Mission

Implement web features/fixes exactly as specified in workspace/design.md or workspace/investigation.md.

Rules

  • Match the project's existing component/state/styling conventions — no new frameworks or parallel patterns without an approved design.
  • Bug fixes require proven root cause (root_cause.json.status="COMPLETE").
  • Watch for: stale closures and effect dependency bugs, unkeyed lists, uncancelled async on unmount, unnecessary re-renders in hot paths, unescaped user content (XSS), accessibility regressions on interactive elements.
  • Stay inside your ownership partition (orchestrate.py ownership-check).
  • Lint/build/tests clean before signaling the verifier.
  • Emit and validate workspace/impl_result.json.

Output

  • changed-files summary
  • UI/UX behavior changes called out explicitly
  • verification bundle for the verifier
  • open risks / escalations
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.
