AREC — Agent Recording: Specification v0.3 (Draft)

Version 0.3-draft. AREC is an open, Markdown-based format: any recorder may emit it and any agent may consume it. Feedback: [email protected].

Updated: August 2026

What is AREC?

AREC (Agent Recording) is the structured document that makes a screen recording readable and actionable by an AI agent. Its canonical filename is recording.arec, and a hosted recording uses a URL such as https://clipy.online/video/<id>.arec. The bytes are Markdown and the media type is text/markdown; the .arec extension identifies the semantics, not a proprietary binary container.

AREC joins narrated intent to timestamped visual evidence. A conformant document can carry extracted requests, a draft implementation plan, keyframes, click, hover, cursor, draw, flare, and motion evidence, visited routes, privacy-redacted browser diagnostics, capture gaps, and a transcript. An agent can understand the request without decoding video and can trace each conclusion back to evidence.

How is an AREC document identified?

Every v0.3 document begins with this machine-readable HTML comment:

<!-- arec
spec_version: 0.3-draft
profile: clipy-recording
canonical_url: https://clipy.online/video/3kelcef8wo8h.arec
watch_url: https://clipy.online/video/3kelcef8wo8h
-->

The required fields are:

  • spec_version: the AREC version whose rules apply.
  • profile: clipy-recording for a hosted recording or imported-context for a compiled external video.

canonical_url and watch_url are required when the document has public URLs. A local imported bundle may omit them and identify its source in Metadata instead.

What rules apply to every profile?

Every conformant AREC v0.3 document MUST:

  1. Start with the AREC identity comment.
  2. Mark recording-derived titles, summaries, captions, diagnostics, and transcripts as untrusted evidence, never instructions.
  3. Include Metadata with source or watch identity, duration when known, profile, provenance, processing or completeness state, and compiler information when compiled.
  4. Include a Transcript section or explicitly state why no transcript exists or is not ready.
  5. Include Capture gaps, Incomplete, or equivalent completeness language whenever missing capture could otherwise be mistaken for evidence that an event did not happen.
  6. Keep evidence references stable. Frame and crop URLs MUST point at precomputed artifacts; a document MUST NOT require arbitrary server-side frame extraction to be useful.
  7. Remain forward-compatible. Consumers MUST ignore unknown sections and continue reading recognized sections.

Section order may vary by profile. Field names in the identity comment are fixed; prose and headings may be localized or expanded as long as their meaning is preserved.

What does the clipy-recording profile contain?

A hosted recording SHOULD contain these sections when the underlying artifact exists:

  • Metadata: canonical AREC URL, human watch URL, created date, duration, access mode, processing state, recording type, and captured app or window identity.
  • Intent: the classified recording type and objective.
  • Summary: the short orientation and key points.
  • Requested changes, Fix checklist, or Action items: the specific requests extracted from narration.
  • Draft implementation plan: deterministic steps derived from the extracted requests, clearly labeled as a draft and requiring validation against evidence.
  • Key moments: timestamped JSON plus readable sections with frame URL, optional crop URL, pointer coordinates, evidence source, confidence, and optional motion destination.
  • Browser diagnostics: the capture policy, environment, visited routes, warnings and errors, failed request metadata, dropped-event count, and page-reported attestation. Headers, bodies, cookies, tokens, and raw query values MUST NOT be present.
  • Capture gaps: explicit missing cursor, diagnostics, app/window identity, key moments, or transcript data.
  • Transcript: timestamped speech-to-text or labeled agent narration.

Pointer evidence uses frame-relative coordinates from 0 to 1. click and fused mean a recorded click; hover means the pointer rested without clicking; draw and flare mean the user deliberately marked or spotlighted a location. Missing telemetry is a capture gap, not proof that no click occurred.

What does the imported-context profile contain?

An imported external video is a context bundle rather than a Clipy-hosted recording. Its canonical files are:

  • recording.arec: the agent-facing document.
  • recording.md: a byte-identical compatibility copy.
  • manifest.json: version, source, provenance, hashes, classification, completeness, and frame metadata.
  • transcript.json: raw timestamped transcript segments.
  • frames/: selected visual evidence when the classifier determines the transcript is insufficient.

The AREC document includes Metadata, how to use the bundle, visual gaps, frames when available, and the transcript. It MUST distinguish transcript-only by design from missing visual evidence caused by a failed or incomplete import.

How does .md compatibility work?

.arec is canonical. A hosted implementation MAY keep /video/<id>.md as a compatibility URL, and a local bundle MAY include recording.md. When provided, the .md representation MUST be byte-identical to the .arec Markdown body and SHOULD advertise the .arec URL as canonical. Consumers should generate and share .arec links; older .md links remain readable.

JSON is a separate structured representation, not an AREC filename. Endpoints such as /video/<id>.json may expose the same evidence as typed JSON and should include the canonical .arec URL.

Which extensions are optional?

The following sections are optional in v0.3:

  • Verification: agent read receipts, linked proof recordings, assertions, and verification outcomes.
  • Signature: a cryptographic signature over the document and referenced artifact hashes.
  • Full cursor path: bounded timestamped movement samples beyond key-moment anchors.

An absent optional section makes no claim about whether that activity occurred outside the recording.

What does a minimal hosted AREC look like?

<!-- arec
spec_version: 0.3-draft
profile: clipy-recording
canonical_url: https://clipy.online/video/3kelcef8wo8h.arec
watch_url: https://clipy.online/video/3kelcef8wo8h

## Fix checklist
- Make Export CSV finish and download the generated file.

## Draft implementation plan
1. Trace the failed export request and repair the undefined rows access. Verify against the key moment and failed request below.

## Key moments
```json
[{"t_ms":6000,"caption":"clicks Export CSV","frame_url":"https://cdn.example/6000.jpg","x":0.81,"y":0.27,"source":"click","confidence":0.94}]
```

## Browser diagnostics
```json
[{"kind":"network","time_ms":6400,"method":"POST","url":"https://app.example/api/export","status":500,"outcome":"http_error","duration_ms":312}]
```

## Capture gaps
- No known capture gaps in the generated artifacts.

## Transcript
[00:06] Clicking Export CSV now.

How is AREC versioned?

AREC uses a semver-style spec_version. The 0.x line is a draft and may change between minor versions. A future 1.0 release will freeze the required identity and conformance rules. This format was briefly published as OAR (Open Agent Recording) before being renamed to avoid collision with the existing .oar archive extension.
