87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a strong, action-oriented code skill: lean, with fully executable Rust examples and exact build commands. Its main gap is workflow clarity—validation checkpoints are implicit rather than explicit, which would otherwise be the only dimension holding it back from full marks.
Suggestions
Add an explicit validation checkpoint in the workflow, e.g. after `cargo build` note "If the build fails, fix the reported errors and rebuild before running the command."
Make the regeneration-safety feedback loop explicit (e.g. "After `fern generate`, re-run `cargo build` to confirm your `custom.rs` still compiles against the new SDK surface").
Consider de-duplicating the file listing between Architecture and Regeneration Safety to tighten token usage.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and token-efficient: mostly executable code, a compact client table, and short command blocks, with no padding explaining CLI or Rust basics Claude already knows. The mild overlap between the Architecture and Regeneration Safety file listings is minor and serves distinct purposes, so it stays at level 3 rather than dropping to 2. | 3 / 3 |
Actionability | It provides a complete, executable `register()` example, concrete `super::sdk::client(ctx)` / `block_on(...)` patterns, an SDK sub-client table, and exact build/run commands (`cargo build`, `RUST_LOG=debug`) that are copy-paste ready, matching the level-3 anchor. | 3 / 3 |
Workflow Clarity | The "Adding a Custom Command" section is clearly sequenced (numbered 1–4 plus Build & Test), but validation is only implicit—`cargo build` acts as the check yet there is no explicit "verify the build passes before running" checkpoint or fix-and-retry loop, matching the level-2 anchor rather than level 3. | 2 / 3 |
Progressive Disclosure | The skill is self-contained with no bundle files present, and its content is well-organized into clearly signaled sections (Overview, Architecture, Adding a Custom Command, Regeneration Safety, Build & Test) that do not need to be split out, so the well-organized single-file structure merits level 3. | 3 / 3 |
