67%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 well-organized, actionable body with concrete code examples, checklists, and well-signaled one-level-deep references. Its main weaknesses are redundancy (routing guidance repeated three times, duplicated sections) and a body long enough that more material should be offloaded to the existing reference files.
Suggestions
Deduplicate the routing/boundary guidance: state it once in 'When to Activate' or 'Integration' and drop the other two restatements, and merge 'Tool Description as Prompt' (Core Concepts) into the Detailed Topics version.
Move the MCP naming tutorial and one of the two worked code examples into references/best_practices.md, leaving a one-line pointer with a 'Read when' trigger in the body.
Add an explicit validate-and-iterate loop to the Tool Selection Framework (e.g., 'if the audit fails at any step, merge/split the tool and re-test') to complement the audit checklist.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and dense with domain-specific guidance, but noticeably redundant: the routing boundaries appear three times (opening paragraph, 'When to Activate', and 'Integration'), 'Tool Description as Prompt' is covered in both Core Concepts and Detailed Topics, and the 'Guidelines' list largely restates the audit checklist. This fits 'mostly efficient but includes some unnecessary explanation or could be tightened' better than anchor 2 because there is no padding explaining concepts Claude already knows at length — the excess is duplication, not filler. | 3 / 5 |
Actionability | Concrete, near-executable guidance throughout: fully qualified MCP name format 'ServerName:tool_name' with correct/incorrect examples, a copy-paste-ready get_customer docstring with 'CUST-######' format and error codes, a runnable optimize_tool_description prompt template, and an 8-item audit checklist. Not score 5 because the optimize_tool_description snippet is a schematic wrapper (pseudocode-like get_agent_response) and some sections (Architectural Reduction) stay at the principle level with no concrete starting recipe. | 4 / 5 |
Workflow Clarity | The Tool Selection Framework gives a clear 5-step sequence and the Tool Audit Checklist provides explicit checkpoints, and testing with actual agent interactions is repeatedly mandated as the validation step. Not score 5 because the frameworks lack an explicit validate-and-iterate loop (what to do when the audit fails, how to re-test after fixes); not score 3 because checkpoints (the checklist, the testing criteria) are explicit rather than missing. This is a design-guidance skill, not a destructive/batch operation, so the cap at 3 does not apply. | 4 / 5 |
Progressive Disclosure | Good structure with two real, one-level-deep references, each clearly signaled with a 'Read when' trigger ('[Best Practices Reference](./references/best_practices.md) - Read when: designing a new tool...'). Minor gaps: the body at ~290 lines inlines substantial material (the full case-study rationale, both worked examples, and the MCP naming tutorial) that could partly live in the references, and the external-resources list is unstructured. It exceeds anchor 3 because what is referenced is clearly signaled and appropriately split; it falls short of anchor 5 because more content should have been pushed down into the existing reference files. | 4 / 5 |
