Conciseness

The body is disciplined for an orchestration skill: a compact Terms table, tight DO/DON'T blocks ("DO NOT call `to_chunks()` in conversion code"), and it assumes Rerun/Arrow knowledge ("Rerun can store arbitrary Arrow-compatible data") without re-explaining it. Minor trimmable framing ("Every dataset is unique, which makes it hard to set universal guidelines…") and small text glitches ("Run census undecodable channels"; the broken line "`is_<validity>`, `has_<attribute>`and the / census") keep it below the lean-everywhere 5 anchor, but it is well above the some-unnecessary-explanation 3 anchor.

Actionability

Concrete, specific instruction throughout: "Write a download script (with caching for faster lookup and options to select what to download)", "Add round-trip tests to ensure the conversion is lossless", "Build them with `Chunk.from_property`", and enumerated survey dimensions (FPS, GOP/codec, missing topics). As an instruction-only orchestration skill it routes executable code to the rerun-* skills and references, so steps like "Write the conversion code using the skills" stay high-level — mostly executable guidance with minor gaps rather than the copy-paste-ready 5.

Workflow Clarity

Steps 0–7 are clearly sequenced with explicit validation and checkpoints: a dedicated conversion-check step ("Add round-trip tests… (original -> base -> original)", "Compare the file sizes… Investigate if there is a gap"), census error handling ("compare decoded rows against the source's own counts, flag the episode in a property, and store the raw bytes"), and user gates ("Pause for user to review the survey", "Pause for user to sign-off on the conversion mapping"). Not 4 because checkpoints are explicit rather than implicit and error paths (undecodable channels, size gaps) carry recovery handling.

Progressive Disclosure

The body is a clear overview with well-signaled, one-level-deep references, each with stated scope: "`references/registering.md` carries the view commands, the registration template, and where querying is covered" and "Read `references/post-processing.md` before deriving a layer from data that is already converted". Both referenced files exist in the bundle, and the rerun-* routing table with a "When to read it" column makes navigation easy. Not 4 because content is appropriately split with no orphaned or buried references.

Specificity

"Convert a multi-modal robotics dataset (MCAP, HDF5, LeRobot, parquet, raw video) into layered Rerun recordings (.rrd) and a catalog-ready dataset" names the domain, formats, and output artifacts, and the trigger clause adds further concrete actions (pipeline "reviewed or extended", "enriched with a new layer"). Multiple specific concrete actions with comprehensive coverage; not 4 because the action list spans convert, ingest, review, extend, and enrich with explicit formats and file extensions rather than having minor gaps.

Completeness

The 'what' is explicit and concrete (convert multi-modal robotics datasets into layered .rrd recordings and a catalog-ready dataset) and the 'when' is explicit with concrete trigger phrases: "Use whenever the user wants a dataset converted or ingested into Rerun, a conversion pipeline reviewed or extended, or an existing dataset enriched with a new layer". Clearly answers both what and when; not 4 because the when-clause is already fully explicit, including indirect phrasings users actually say.

Trigger Term Quality

It quotes the exact phrases a user would naturally say — "'convert X to rrd', 'ingest this dataset', 'enrich this dataset', or 'append a layer'" — alongside format names and extensions (MCAP, HDF5, LeRobot, parquet, .rrd). Comprehensive natural-term coverage including synonyms and quoted user paraphrases; not 4 because no common variation is missing.

Distinctiveness Conflict Risk

A clear niche (robotics dataset conversion orchestration) with distinct triggers like "convert X to rrd" and "ingest this dataset", and it explicitly separates mechanics ("Routes to the rerun-* skills for Rerun mechanics"). Not 5 because the rerun-* family it routes to (rerun-mcap, rerun-parquet, rerun-lerobot) shares the same format triggers, leaving minor overlap risk with closely related skills; not 3 because the description carves out the conversion-pipeline role distinctly from those mechanics skills.
