Names the domain (Amplitude via Rube MCP/Composio) and lists some actions (events, user activity, cohorts, user identification), but these are more like category labels than concrete actions. It doesn't specify what it does with events or cohorts (create, query, delete?).

The 'what' is partially addressed (automate Amplitude tasks), but there is no explicit 'Use when...' clause or equivalent trigger guidance. The instruction to 'always search tools first' is operational guidance rather than a trigger condition. Per rubric, missing 'Use when' caps completeness at 2.

Includes relevant keywords like 'Amplitude', 'events', 'user activity', 'cohorts', and 'user identification', which are natural terms. However, it misses common variations users might say like 'analytics', 'tracking', 'funnel', 'retention', or 'Amplitude API'.

The description is quite specific to Amplitude via Rube MCP (Composio), which is a distinct niche. It's unlikely to conflict with other skills given the specific tool and platform references.

The skill is reasonably well-structured but contains significant repetition—pitfalls about user_id vs internal ID are stated in workflows 2, 3, the Common Patterns section, AND the Known Pitfalls section. The Known Pitfalls section largely restates information already covered in individual workflow pitfalls. Some explanatory text could be trimmed (e.g., 'When to use' descriptions are somewhat obvious).

Tool sequences and key parameters are clearly listed, which is helpful. However, there is no truly executable code—the 'code' blocks are pseudocode step lists rather than actual tool invocations with complete parameter examples. The JSON example for user properties is a good concrete snippet, but most workflows lack copy-paste-ready tool call examples with full parameter structures.

Multi-step workflows are clearly sequenced with numbered steps, prerequisite/required/optional labels, and explicit validation patterns (e.g., the async cohort operation pattern with status checking loop, the ID resolution prerequisite before GET_USER_ACTIVITY). The setup section includes a verification step before proceeding.

The content is well-organized with clear sections and a quick reference table, but it's a monolithic ~180-line document with no bundle files to offload detail into. The repeated pitfalls and detailed parameter lists for each workflow could be split into separate reference files. The single external link to Composio docs is appropriate but the skill itself could benefit from splitting detailed workflow docs out.
