webshop-price-checker

This skill scans product listings or detail pages to verify if an item's price meets a specified budget constraint. It is triggered when evaluating a potential product for purchase. It extracts the price from the displayed information (e.g., '$164.95') and compares it against the maximum allowed budget, outputting a boolean decision on whether the item is within budget.

Content

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A compact, well-sequenced instruction body for a simple read-only skill, but it leans on a script that is missing from the bundle and fails to link the reference file that does exist. Adding the actual script invocation and referencing the patterns file would close the main gaps.

Suggestions

Add the concrete command for running the script (e.g., `python scripts/check_price.py --price "$164.95" --budget 200.00`) so the Execute Check step is copy-paste executable, and include the script in the bundle.

Link the existing reference from the body, e.g. 'See [price_patterns.md](references/price_patterns.md) for common price string formats and budget phrasings', so the bundled reference is actually discoverable.

Tighten the Notes by removing the redundant budget-phrasing example already covered in the reference file, keeping the body focused on the decision logic.

Dimension	Reasoning	Score
Conciseness	Mostly lean and assumes Claude's competence, with only minor over-explanation such as 'The budget is typically expressed as a dollar amount (e.g., lower than 200.00 dollars)' that could be trimmed.	4 / 5
Actionability	Names the concrete script 'check_price.py' and its inputs but gives no executable invocation (e.g., command line or argument syntax), and the referenced script is not present in the bundle, leaving key execution details missing.	3 / 5
Workflow Clarity	A clear four-step sequence (Identify Budget, Locate Price, Execute Check, Make Decision) with a True/False decision branch and a price-not-found fallback; this is a read-only check so the destructive-operation validation cap does not apply, though explicit checkpoints are minimal.	4 / 5
Progressive Disclosure	The body is well-sectioned into Process and Notes, but the bundled 'references/price_patterns.md' is never linked from the body and the 'check_price.py' script the body depends on is absent from the bundle, leaving references unsignaled and a dangling path.	3 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that clearly conveys both capability and trigger conditions with concrete actions and a worked price example. Only minor gap is missing a few natural budget phrasings users might say.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'scans product listings or detail pages', 'extracts the price', 'compares it against the maximum allowed budget', 'outputting a boolean decision' — covering the full workflow comprehensively.	5 / 5
Completeness	Explicitly states both what it does (scan/extract/compare/output boolean) and when to use it via the explicit trigger clause 'It is triggered when evaluating a potential product for purchase.'	5 / 5
Trigger Term Quality	Includes natural terms like 'price', 'budget', 'product', 'purchase', and a concrete '$164.95' example, but omits common variations users say such as 'under $X', 'within budget', or 'affordable'.	4 / 5
Distinctiveness Conflict Risk	Occupies a clear niche — price-vs-budget verification for purchase decisions — with distinct triggers and minimal overlap risk with other skills.	5 / 5
	Total	19 / 20 Passed
