Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00109 | $0.00281 |
| Opus 5 | $0.00055 | $0.00140 |
| Sonnet 5 | $0.00022 | $0.00056 |
| Haiku 4.5 | $0.00011 | $0.00028 |
Grade A, and why
mismatch-diagnoser 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 5d 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
Resolve plugin root as ${PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$(cat "$HOME/.config/ui-clone-skills/root" 2>/dev/null)}} if $PLUGIN_ROOT is unset.
Read $PLUGIN_ROOT/skills/ui-reverse-engineering/diagnosis.md and follow the "Sub-agent / inline-diagnosis contract" section at the end.
The Root Cause A-R catalog is the canonical source. Codex hosts use the native mismatch-diagnoser role from .codex/agents/mismatch-diagnoser.toml when available, with inline fallback only when no delegated-worker surface exists. Your output JSON schema is identical across hosts, ensuring cross-host parity.
Do not apply fixes. Return diagnosis only.
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.

mismatch-diagnoser is an agent published in the GitHub repository voidmatcha/ui-clone-skills (9 stars, last pushed today), licensed Apache-2.0. It adds 109 tokens to every session and 281 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

genpage-page-builder
Generates a single complete .tsx generative page from a plan document and schema. Reads genpage-plan.md for page specification, RuntimeTypes.ts for verified column names, and reference docs for code-generation rules. Writes one .tsx file per invocation. Called by the genpage skill in parallel — not invoked directly by…

Power Apps Code App Architect specializing in React/Vite architecture, Dataverse integration, connector patterns, and Power Platform deployment. Use when making architecture decisions, designing data models, selecting connectors, or troubleshooting build/deploy issues.
genpage-edit-planner
Plans edits to an existing generative page. Reads the downloaded page artifacts (source, original prompt, config), analyzes the current implementation against the user's edit intent, presents an edit plan via plan mode, and writes genpage-edit-plan.md for the orchestrator to execute. Called by the genpage skill — not…
quality-fixer-frontend
Specialized agent for verifying React projects and fixing frontend quality failures within the current task scope. Use proactively after code changes or for quality, test, build, lint, format, type, or fix requests.
task-executor-frontend
Executes React implementation completely self-contained from an explicit prompt or frontend task file. Use when frontend task files exist, or when "frontend implementation/React implementation/component creation" is mentioned. Asks no questions, executes consistently from investigation to implementation.
raindrop-gardener
Tends the bookmark annex — same discipline, different soil. Use this agent for read-only Raindrop.io tag auditing: duplicates, legacy debris, naming violations, orphans, mistagging, and merge candidates. Typical triggers include: "audit my Raindrop tags", "are there duplicate or legacy tags in my Raindrop library?"…
