subagent-creator

Guide for creating AI subagents with isolated context for complex multi-step workflows. Use when users want to create a subagent, specialized agent, verifier, debugger, or orchestrator that requires isolated context and deep specialization. Works with any agent that supports subagent delegation. Triggers on "create subagent", "new agent", "specialized assistant", "create verifier". Do NOT use for Cursor-specific subagents (use cursor-subagent-creator instead).

Content

65%

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

The body is actionable and well structured with strong worked examples, but it carries conceptual padding Claude doesn't need, omits explicit validation checkpoints in its creation workflow, and is monolithic with no file-level progressive disclosure. Targeted trimming and a feedback loop would raise the weaker dimensions.

Suggestions

Trim the 'What are Subagents?' intro and ASCII decision tree to essentials, or move them to a reference file, to remove concepts Claude already knows and improve conciseness.

Add an explicit validation step to the creation process (e.g., 'Test the description by simulating a delegation request; if the wrong subagent triggers, revise the description and re-test') to introduce a validate→fix→retry feedback loop.

Split the four common-pattern examples and the templates into a separate references/ file (e.g., PATTERNS.md) and link to it from SKILL.md so the main file is a lean overview.

DimensionReasoningScore

Conciseness

Mostly efficient and instruction-focused, but the conceptual 'What are Subagents?' intro, the ASCII decision tree, and repeated template blocks add scaffolding Claude already knows (delegation/isolation concepts); not 3 due to this unnecessary conceptual padding, not 1 because it avoids library/tutorial verbosity.

2 / 3

Actionability

Provides a concrete metadata template, a prompt template, and four fully fleshed-out worked examples (verifier, debugger, security-auditor, code-reviewer) that are copy-paste ready, matching the 'fully executable/specific examples' anchor; not 2 because it goes beyond placeholder pseudocode to complete examples.

3 / 3

Workflow Clarity

The creation process is clearly numbered (Define purpose → Configure metadata → Write prompt) but lacks explicit validation checkpoints or a validate→fix→retry feedback loop; 'Test the description' is a one-line best practice rather than a sequenced validation step, so it sits at the 'steps listed but validation gaps' anchor.

2 / 3

Progressive Disclosure

No bundle files exist and the ~300-line body keeps all patterns and templates inline in one monolithic file rather than splitting them into reference files; sections are well organized so it is above 1, but it is too large/monolithic for the single-file exception to reach 3.

Description

100%

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

The description is excellent: third-person voice, concrete capabilities, natural trigger terms, explicit when/what guidance, and a strong conflict-prevention exclusion. No changes needed.

DimensionReasoningScore

Specificity

Names the domain and enumerates multiple concrete deliverable types ("specialized agent, verifier, debugger, or orchestrator" with "isolated context"), matching the 'lists multiple specific concrete actions' anchor; not 2 because it goes beyond naming a single domain to listing distinct outputs.

3 / 3

Completeness

Explicitly answers both what ("Guide for creating AI subagents with isolated context") and when ("Use when users want to create a subagent..."), with an explicit 'Use when' clause plus 'Triggers on' and a 'Do NOT use' exclusion; matches the 'clearly answers both what AND when' anchor.

3 / 3

Trigger Term Quality

Includes natural phrasings a user would say ("create subagent", "new agent", "specialized assistant", "create verifier") with good coverage of common variations, matching the 'good coverage of natural terms' anchor; not 2 because it lists several common phrasings rather than one.

3 / 3

Distinctiveness Conflict Risk

Clear niche (subagent creation) with distinct triggers and an explicit negative-scope guard ("Do NOT use for Cursor-specific subagents (use cursor-subagent-creator instead)") that prevents conflicts, matching the 'clear niche with distinct triggers' anchor.
