75%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.
The body is a tight, actionable guide: executable Rust code, an architecture map, a regeneration-safety table, and build commands, with almost no token waste. The main defects are the empty "Available SDK Clients" section that promises sub-clients it never lists, and the absence of an explicit post-edit validation step.
Suggestions
Fix the "Available SDK Clients" section: either list the actual sub-clients (or show how to discover them, e.g. inspect acme_cli_sdk::api::Client) instead of the current placeholder line "(Sub-clients are derived from the API spec at generation time.)".
Add a validation checkpoint after editing custom.rs, e.g. "Verify with `cargo build && acme-cli my-command --help` before moving on", to close the workflow gap.
State where the .fernignore file lives (or that it is created by fern init) so the regeneration-safety claim is actionable rather than asserted.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes competence — no padding explaining Rust, clap, or codegen concepts — with only minor redundancy (the .fernignore protection is stated in prose at "protected by .fernignore — fern generate will never overwrite it" and again in the Regeneration Safety table). | 4 / 5 |
Actionability | The registration example is concrete, executable Rust code with real commands ("cargo build", "RUST_LOG=debug acme-cli ..."), but the "Available SDK Clients" section promises "the following sub-clients" and then lists none — a visible gap in an otherwise copy-paste-ready guide. | 4 / 5 |
Workflow Clarity | The edit → build → run sequence is clearly laid out with a numbered section and concrete commands, plus an error-recovery hint (RUST_LOG=debug), but there is no explicit validation checkpoint (e.g. confirming the build succeeds or the command appears in --help) after editing custom.rs. | 4 / 5 |
Progressive Disclosure | The ~100-line body is well organized with clear sections (Overview, Architecture, Adding a Custom Command, Regeneration Safety, Build & Test) and no inlined bulk content; it is above the <50-line simple-skill threshold and has no external references, so structure is good but not exemplary. | 4 / 5 |
