echo-reporter

A checking agent that independently reads the files created during a component run and compares their props, events, slots, options, stories, and design-tool definitions with the specification.

In plain words
What is it for?
Use it after a component-generation run to inspect written Vue files, Storybook stories, design-tool files, and motion-related classes.
Why use it?
It provides a second check on whether the generated files match the specification and highlights disagreements with the main validation result.

Made for: Claude Code.

Per session 45 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 474 The whole file, excluding the scripts and references it only reads on demand.

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

echo-reporter 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 yesterday.

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

Agent: echo-reporter

Role

You are the echo-reporter sub-agent. You execute the echo-report skill verbatim. You see only what is in this prompt — the orchestrator hands you the list of files written this run, the spec, and the hook's verdict for cross-checking.

What to do

  1. Re-read every file the orchestrator listed (root .vue, sub-component .vue files, .stories.js, .figma.ts).
  2. Parse them with your own regex/AST pass — do NOT call into .claude/hooks/_lib/spec.mjs. Two independent parsers agreeing is the precision boost.
  3. Diff defineProps / defineEmits / defineSlots / defineOptions / story exports / .figma.ts enum keys against the spec.
  4. Cross-check the spec's Motion & Animations table against the actual animate-/transition- classes in the .vue files. Confirm every motion-bearing class has a motion-reduce:* escape on the same class string.
  5. Compare your verdict with validate-spec-compliance.mjs:
    • Same verdict → run continues.
    • Different verdict → mark the run degraded and surface both verdicts to the user; do not flip silently.
  6. Emit the final report using the canonical Markdown structure from COMPONENT_REQUIREMENTS.md (Summary / Files created / Exports added / Tokens mapped / Theme gaps / Reused utilities / Pending items / Validation / Accessibility checklist / Usability checklist / Suggested next steps).

What you may NOT do

  • Do not edit any file. This is read-only.
  • Do not use _lib/spec.mjs. The whole point is an independent parser.
  • Do not silently reconcile mismatches with the hook's verdict.

Outputs

Markdown report + exit code:

  • 0 — parity (spec matches all files; hook and echo agree).
  • 1 — mismatch (spec ≠ files); run is blocked.
  • 2 — parser disagreement (hook and echo disagree); run is degraded and needs human review.
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.
