68%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 exemplary in its token efficiency but under-specified in execution: the single command lacks the inputs and paths needed to run it, and a batch export operation ships with no validation of output. The closing self-modification instruction ("update this skill automatically so later runs work") is vague direction rather than actionable guidance and dilutes an otherwise crisp one-step skill.
Suggestions
Complete the command with execution details: the full path to tool.py, the arguments identifying which records to export and where output is written, and one worked example invocation.
Add a post-export validation checkpoint (e.g., verify the JSON parses and the exported record count matches the source) since this is a batch operation — this would lift the workflow_clarity cap.
Replace the vague self-modification line with a concrete maintenance note under its own heading (e.g., a "Deprecated commands" section documenting what to do when an invocation changes), or remove it, since "update this skill automatically" is not executable direction.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is three terse lines ("Keep credentials out of logs.", "Use `python3 tool.py --legacy` for JSON output.", plus the maintenance note) with zero padding and no explanation of concepts Claude already knows. Every line carries information; it matches "Lean and efficient; assumes Claude's competence; every token earns its place". | 5 / 5 |
Actionability | One concrete command is present ("python3 tool.py --legacy") but it is missing key details: no path or location of tool.py, no arguments indicating which records or what output destination, and "Keep credentials out of logs" states a constraint without any mechanism for achieving it. This matches "Some concrete guidance but incomplete... missing key details"; it is not level 4 because the gaps exceed minor — the command cannot be run as given without guessing inputs. | 3 / 5 |
Workflow Clarity | Exporting local records is a batch operation, and the body includes no validation or verification step (e.g., confirming the JSON parses or the record count matches), which caps workflow clarity at 3 per the batch-operations rule. The single step is stated but with implicit checkpoints only; it is not level 2 because the action given is unambiguous in intent and correctly sequenced for a one-step task. | 3 / 5 |
Progressive Disclosure | The skill is under 50 lines, self-contained, references no external files (and none exist in the bundle), and keeps everything appropriately in SKILL.md under a single heading. It does not reach 5 because the three lines mix distinct concerns — a security constraint, an invocation command, and a maintenance instruction — without section separation that would make navigation clearer. | 4 / 5 |
