create-custom-agent

Guide an Amplitude user through building a custom agent by suggesting use cases grounded in their role and data, shaping the idea into a well-formed spec, and generating a ready-to-run Global Agent deeplink that creates it. Use to create, build, or set up a custom agent, automate a recurring analysis, or put a repeated report on a schedule.

Quality

Content

78%Weight 40%Scale 1-5

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

A well-structured, actionable skill body that sequences a multi-step intake-to-delivery workflow with explicit checkpoints and offloads detail to four real one-level-deep reference files. Minor conciseness and worked-example gaps keep most dimensions at 4.

Suggestions

Tighten the behavioral-coaching section ('How to behave') into shorter imperatives to lift conciseness toward a 5.

Add one fully URL-encoded worked example (e.g. a filled prompt rendered to an app.amplitude.com deeplink) so the actionability guidance is copy-paste ready end-to-end.

Show an explicit validate-and-flag feedback loop after Step 5 (e.g. 're-read the filled prompt, confirm every field is non-empty or flagged') to push workflow clarity to 5.

DimensionReasoningScore

Conciseness

Mostly efficient and actionable with purposeful steps, a table, and URL templates rather than padded concept explanations; a few coaching passages ('Help, don't gatekeep') could be trimmed, keeping it just below a 5.

4 / 5

Actionability

Provides concrete, executable guidance — a 9-field intake table with coaching, a fill-in prompt template, explicit URL-encoding character mappings, and a delivery format with a named-link example — with minor gaps such as no fully worked encoded example.

4 / 5

Workflow Clarity

A clear 7-step sequence with explicit checkpoints (skip MCP step if unavailable, flag defaulted fields, conditional Slack/experiment reminders); not quite the full validate-fix-retry feedback-loop depth of a 5.

4 / 5

Progressive Disclosure

The body is a concise overview that signals four one-level-deep references (use-cases.md, best-practices.md, prompting-instructions.md, examples.md), all of which exist as real files, with clear navigation — matching the top anchor.

Description

87%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, specific description that names concrete actions and gives explicit trigger guidance in third-person voice. It clearly answers both 'what' and 'when' and occupies a distinct niche.

DimensionReasoningScore

Specificity

Lists several concrete actions — 'suggesting use cases grounded in their role and data', 'shaping the idea into a well-formed spec', and 'generating a ready-to-run Global Agent deeplink' — with only minor gaps; not quite the comprehensive multi-action coverage of a 5.

4 / 5

Completeness

Explicitly states both what it does (guide a user through building a custom agent via suggestion, spec-shaping, deeplink generation) and when to use it with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Includes natural phrases users would say ('create, build, or set up a custom agent', 'automate a recurring analysis', 'put a repeated report on a schedule') with good coverage, though a few synonyms are absent.

4 / 5

Distinctiveness Conflict Risk

Tightly scoped to Amplitude custom agents and Global Agent deeplinks — a clear niche with distinct triggers and minimal overlap risk with other skills.
