AC historical-data-compare-claw
历史数据比对虾 — 专注于环比、同比、趋势等数据差异分析。激活场景：当用户提供两期或多期历史数据（Excel/CSV/数据库导出等），要求进行同比分析、环比分析、趋势对比、差异排查、变动归因、KPI变动说明、或"和上个月比怎么样"、"今年比去年如何"等数据对比类问题时触发。也适用于多维度数据切片对比（按区域、品类、渠道等维度拆解差异）。核心价值：趋势洞察——翻阅历史记录，清晰告诉决策者当下的变量。触发关键词：同比、环比、趋势、对比、差异、变动、变化、涨跌、增减、和上期比、和去年同期比、period over period、YoY、MoM、QoQ、同比分析、环比分析、趋势分析、数据对比。
As a process C 53/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec
- warning
description-no-whendescription does not say WHEN to use the skill (no "use when")
Process rating: all ten parameters 53/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 100Tools and files. No external tools needed
- 100Steps. 25 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 554 tokens
- 100Running it twice. No mutating operations
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
Quality signals
- +4Description does not say when NOT to use the skill (false activations)
- +3Output format is not stated: the model decides each time
- -41 reference files, but SKILL.md never points to them: the model will not open them
- +1No license
- +2Single-language instructions
- +5Description quotes 2 example trigger phrases
- +3Description length 296: enough signal without eating the budget
- +4Structure: 11 headings
- +3Step-by-step instructions: 25 items
- +4Has examples (2 code blocks)
- +3All 1 scripts are documented
