76%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A high-signal, actionable reference for a non-trivial experimental API, with complete runnable examples and a useful builder table. Its main weakness is workflow clarity: the end-to-end process is implied rather than presented as an explicit, checkpointed sequence.
Suggestions
Add an explicit numbered "Workflow" section (1. fill the rerun-data-model mapping table → 2. configure ParquetReader.stream() → 3. drop /__properties → 4. apply lenses → 5. .to_chunks()) with the stream() schema validation framed as a checkpoint and an error-recovery note, rather than leaving the sequence implied across sections.
De-duplicate the Gotchas section against the body: gotchas #3, #4, #5, #9 repeat the static_columns raise behavior, the `data` struct naming, prefix-stripped field names, and the keep-columnar guidance already stated in their respective sections — collapse these to one-line cross-references or remove the redundancy.
Consider moving the full lens builder table and the Selector grammar into a bundled reference file (e.g. references/lens-builders.md) referenced from SKILL.md, so the main file stays a lean overview and progressive disclosure reaches a cleaner split.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely efficient and free of basic-concept over-explanation, but the Gotchas section restates body content (static_columns raise behavior, the `data` struct naming, prefix-stripped field names, keep-the-pipeline-columnar) that could be trimmed; short of the every-token-earns-its-place leanness of a 5. | 4 / 5 |
Actionability | Provides copy-paste-ready runnable examples with imports for the primary flows (end-to-end Transform3D, Points3D via to_packed_component), an exhaustive concrete builder signature table, and a help command — covering the common cases fully. | 5 / 5 |
Workflow Clarity | The process is only implied (fill the rerun-data-model mapping table, configure stream(), drop /__properties, apply lenses) and validation exists (schema check at stream(), static-column raise), but there is no explicit numbered sequence with checkpoints or error-recovery framing, matching the 3 anchor's implicit-sequence characterization. | 3 / 5 |
Progressive Disclosure | Well-sectioned with a clearly signaled References section pointing one level deep to source files and sibling skills, but it is a monolithic ~240-line document with the builder table and selector grammar inlined rather than split into bundled reference files, so it does not reach the 5 anchor's "content appropriately split". | 4 / 5 |
