echo-report

A final checker that rereads files created during a component build and compares them with the component specification. It uses a separate parser to check the Vue files, Storybook story, and optional Figma mapping.

In plain words
What is it for?
Use it as the final verification step after generating a component, its Storybook story, and its Figma mapping.
Why use it?
It catches missing or extra props, events, slots, stories, or mappings after other checks have run. Differences between the two checks are flagged for human review.

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-report 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.

Skill: echo-report

Purpose

After scaffolding + storybook + code-connect have written files, this skill re-reads them from disk, re-parses defineProps / defineEmits / defineSlots / story exports / .figma.ts mappings, and produces a diff against the spec. If validate-spec-compliance.mjs (the PostToolUse hook) and this skill disagree on any artifact, the run is marked degraded and a human is asked to review.

Two parsers agreeing is the precision boost.

When to invoke

  • Step 7 of /component-create, after code-connect-write (or its skip).

Inputs

  • The list of files the orchestrator's run log says were written.
  • The full text of .specs/<name>.md.
  • The output of validate-spec-compliance.mjs for the same files (passed by the orchestrator).

Workflow

  1. Re-read every <name>.vue, every sub-component .vue, the <Name>.stories.js, and (if present) <name>.figma.ts.
  2. Independent parsing. Do not call into _lib/spec.mjs. Parse with a hand-rolled regex/AST pass:
    • defineProps<{...}>() block → list of { name, type, optional, default }.
    • defineEmits<{ name: [args] }>() → list of { name, payload }.
    • defineSlots<{ name(...): unknown }>() → list of { name }.
    • defineOptions({ name: '...' }) → component name.
    • provide(<Key>InjectionKey, ...) / inject(<Key>InjectionKey) → composition marker.
    • Story file: export const <Name> names + their args.
    • .figma.ts: figma.connect(<Component>, '...', { props: {...} }) keys.
  3. Diff against spec.
    • Props in .vue ≠ spec.Props → block.
    • Events in .vue ≠ spec.Events → block.
    • Slots in .vue ≠ spec.Slots → block.
    • Sub-components: every <name>-<part>.vue matches spec.Sub-components.
    • Story exports ≠ spec.Stories → block.
    • .figma.ts enum keys ≠ spec.Props values → block.
  4. Animations cross-check. The spec's ## Motion & Animations section lists the expected animate-* / transition-* classes per state. Grep the .vue files:
    • Every animation class in the spec must appear at least once in the .vue.
    • Every animation class in the .vue must appear in the spec.
    • Each animate-* class on a transformable element must be paired with motion-reduce:animate-none or motion-reduce:transition-none (or have a same-line escape). Spec says _none_ → zero animate-* / transition-* classes allowed.
  5. Cross-check with the hook. Compare your diff with the validate-spec-compliance.mjs output. Same verdict → run continues. Different verdict → mark the run degraded and ask the user to investigate.
  6. Emit the final report using the structure in 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 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.

echo-report is a skill published in the GitHub repository aziontech/webkit (2 stars, last pushed 4d ago), licensed MIT. It adds 36 tokens to every session and 1,079 once invoked, about $0.0002 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.
