71%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-structured, honest, and reasonably lean instruction skill with a strong two-mode workflow and an explicit anti-fabrication checklist. Its main weaknesses are that the executable scanner and smoke test in scripts/ are completely undocumented in SKILL.md, and the workflow lacks result-validation checkpoints (time-window verification, empty-result handling).
Suggestions
Document the bundled scanner in SKILL.md with a Quick start command (e.g., `python scripts/main.py --sources biorxiv medrxiv --days 14 --output markdown`) and note scripts/requirements.txt and scripts/smoke_test.py, so the executable path is discoverable.
Add a validation checkpoint in Step 2/3: verify each fetched paper's posting date falls within the requested time window, and define behavior for empty or partial API results (e.g., report the gap explicitly rather than proceeding silently).
Trim redundancy: the blockquote redirect under Input Validation duplicates the out-of-scope list above it, and the persona opener sentence can be dropped without losing guidance.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean for its scope: no explanations of concepts Claude already knows, operational rather than tutorial in tone, and genuinely useful environment-specific notes ('May be blocked by Cloudflare in automated environments', RSS accessible at export.arxiv.org). Minor trimmable padding: the persona opener ('You are an expert research horizon-scanner...') and the blockquote redirect ('Emerging Topic Scout focuses on...') that duplicates the out-of-scope list immediately above it. Not a 5 due to these small redundancies; well above a 3 since there is no real over-explanation. | 4 / 5 |
Actionability | Concrete, copy-paste-ready elements: manual search URL templates for bioRxiv/medRxiv/arXiv, a default time window (14 days), a structured report format, and a deterministic two-mode decision path. Not a 5 because the core instruction 'Query the relevant preprint server API or RSS feed' defers the actual API mechanics to references/README.md, and the fully executable scanner in scripts/ (main.py, with a documented CLI: 'python main.py --sources biorxiv medrxiv --days 7 --output markdown') is never mentioned in the body. Not a 3 because what is present is executable, not pseudocode. | 4 / 5 |
Workflow Clarity | Clear four-step sequence (clarify parameters → execute scan → organize/report → hard rules) with input validation in Step 1 ('ask the user to narrow to a sub-field'), an explicit fallback feedback loop (live access fails → knowledge-synthesis mode, clearly labeled), and a hard-rules checklist ('Never fabricate paper titles, DOIs...'). Not a 5 because there are no checkpoints for verifying fetched papers fall inside the requested time window or handling empty/partial API results before reporting. | 4 / 5 |
Progressive Disclosure | SKILL.md is a concise overview and its one reference (references/README.md) is real, one level deep, and clearly signaled in a References section. However, scoring against the actual bundle structure reveals a significant organization gap: the entire scripts/ directory (main.py scanner, smoke_test.py, requirements.txt) is never referenced from the body, leaving the most executable asset undiscoverable. This goes beyond the 'minor organization gaps' of anchor 4, though it is not the buried/inline pattern of anchor 3's typical failure. | 3 / 5 |
