A frontend coding agent for building the React single-page application in the web/ directory. It works on boards, backlogs, sprints, and issue screens with mobile and accessibility requirements.

Use it to build and test React screens, accessible drag-and-drop interactions, forms, navigation, and data-fetching UI.

It helps implement one web feature at a time while following the project's UI, form, routing, and test-driven development rules. TDD means writing tests as part of developing each feature.

Per session 82 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 451 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin unknown No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.00451
Opus 5.5	$0.00033	$0.00180
Sonnet 5.5	$0.00016	$0.00090
Haiku 4.5	$0.00008	$0.00045

Security

Grade A, and why

web 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 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.
