Command Creator

Create command files that delegate to skills. Commands live in .claude/commands/ and are auto-discovered by Claude Code as /commandname.

Step 0: Check for Existing Command

Before creating, check if command already exists:

test -f .claude/commands/<command-name>.md && echo "EXISTS" || echo "NEW"

If EXISTS → use Read to inspect the current command file, then Edit to apply changes directly. Run the post-creation integration steps (Step 4) after updating.

If NEW → continue with Step 0.5.

Step 0.5: Companion Check

Before proceeding with creation, run the ecosystem companion check:

  1. Use companion-check.cjs from .claude/lib/creators/companion-check.cjs
  2. Call checkCompanions("command", "{command-name}") to identify companion artifacts
  3. Review the companion checklist — note which required/recommended companions are missing
  4. Plan to create or verify missing companions after this artifact is complete
  5. Include companion findings in post-creation integration notes

This step is informational (does not block creation) but ensures the full artifact ecosystem is considered.

When to Use

  • Creating user-facing shortcuts to skills
  • Simplifying complex skill invocations
  • Providing memorable command names for common workflows

Command File Format

All commands use this pattern:

---
description: Brief description of what this command does
disable-model-invocation: true
---

Invoke the {skill-name} skill and follow it exactly as presented to you

Example: /tdd command

---
description: Test-driven development workflow with Iron Laws
disable-model-invocation: true
---

Invoke the tdd skill and follow it exactly as presented to you

Creation Workflow

Step 1: Validate Inputs
// Validate command name (lowercase, hyphens only)
const commandName = args.name.toLowerCase().replace(/[^a-z0-9-]/g, '-');

// Validate target skill exists
const skillExists = await fileExists(`.claude/skills/**/${args.skill}/SKILL.md`);
if (!skillExists) {
  throw new Error(`Target skill not found: ${args.skill}`);
}
Step 2: Create Command File
const commandPath = `.claude/commands/${commandName}.md`;
const description = args.description || `Invoke the ${args.skill} skill`;

const content = `---
description: ${description}
disable-model-invocation: true
---

Invoke the ${args.skill} skill and follow it exactly as presented to you
`;

await writeFile(commandPath, content);
Step 3: Update Command Catalog
const catalogPath = '.claude/context/artifacts/catalogs/command-catalog.md';
const catalogContent = await readFile(catalogPath, 'utf-8');

// Add entry to catalog
const newEntry = `| /${commandName} | ${description} | ${args.skill} |`;

// Insert alphabetically
Step 4: Run Post-Creation Integration
const {
  runIntegrationChecklist,
  queueCrossCreatorReview,
} = require('.claude/lib/creators/creator-commons.cjs');

await runIntegrationChecklist('command', commandPath);
await queueCrossCreatorReview('command', commandPath, {
  artifactName: commandName,
  createdBy: 'command-creator',
});

Post-Creation Integration

After command creation, run integration checklist:

const {
  runIntegrationChecklist,
  queueCrossCreatorReview,
} = require('.claude/lib/creators/creator-commons.cjs');

// 1. Run integration checklist
const result = await runIntegrationChecklist('command', '.claude/commands/<command-name>.md');

// 2. Queue cross-creator review
await queueCrossCreatorReview('command', '.claude/commands/<command-name>.md', {
  artifactName: '<command-name>',
  createdBy: 'command-creator',
});

// 3. Review impact report
// Check result.mustHave for failures - address before marking complete

Integration verification:

  • Command added to command-catalog.md
  • Target skill exists and is valid
  • Command file has proper YAML frontmatter
  • Command is discoverable via /commandname

Usage Examples

Create TDD Command
Skill({
  skill: 'command-creator',
  args: '--name tdd --skill tdd --description "Test-driven development workflow"',
});
Create Debug Command
Skill({
  skill: 'command-creator',
  args: '--name debug --skill debugging --description "Systematic debugging workflow"',
});

Related Skills

  • skill-creator - Create the skills that commands delegate to
  • skill-updater - Update the underlying skill a command delegates to

Memory Protocol (MANDATORY)

Before starting: Read .claude/context/memory/learnings.md

After completing:

  • New command pattern → .claude/context/memory/learnings.md
  • Command creation issue → .claude/context/memory/issues.md
  • Delegation decision → .claude/context/memory/decisions.md

ASSUME INTERRUPTION: If it's not in memory, it didn't happen.

Cross-Reference: Creator Ecosystem

This skill is part of the Creator Ecosystem. When research uncovers gaps, trigger the appropriate companion creator:

Gap DiscoveredRequired ArtifactCreator to InvokeWhen
Domain knowledge needs a reusable skillskillSkill({ skill: 'skill-creator' })Gap is a full skill domain
Existing skill has incomplete coverageskill updateSkill({ skill: 'skill-updater' })Close skill exists but incomplete
Capability needs a dedicated agentagentSkill({ skill: 'agent-creator' })Agent to own the capability
Existing agent needs capability updateagent updateSkill({ skill: 'agent-updater' })Close agent exists but incomplete
Domain needs code/project scaffoldingtemplateSkill({ skill: 'template-creator' })Reusable code patterns needed
Behavior needs pre/post execution guardshookSkill({ skill: 'hook-creator' })Enforcement behavior required
Process needs multi-phase orchestrationworkflowSkill({ skill: 'workflow-creator' })Multi-step coordination needed
Artifact needs structured I/O validationschemaSkill({ skill: 'schema-creator' })JSON schema for artifact I/O
User interaction needs a slash commandcommandSkill({ skill: 'command-creator' })User-facing shortcut needed
Repeated logic needs a reusable CLI tooltoolSkill({ skill: 'tool-creator' })CLI utility needed
Narrow/single-artifact capability onlyinlineDocument within this artifact onlyToo specific to generalize

Ecosystem Alignment Contract (MANDATORY)

This creator skill is part of a coordinated creator ecosystem. Any artifact created here must align with and validate against related creators:

  • agent-creator for ownership and execution paths
  • skill-creator for capability packaging and assignment
  • tool-creator for executable automation surfaces
  • hook-creator for enforcement and guardrails
  • rule-creator and semgrep-rule-creator for policy and static checks
  • template-creator for standardized scaffolds
  • workflow-creator for orchestration and phase gating
  • command-creator for user/operator command UX
Cross-Creator Handshake (Required)

Before completion, verify all relevant handshakes:

  1. Artifact route exists in .claude/CLAUDE.md and related routing docs.
  2. Discovery/registry entries are updated (catalog/index/registry as applicable).
  3. Companion artifacts are created or explicitly waived with reason.
  4. validate-integration.cjs passes for the created artifact.
  5. Skill index is regenerated when skill metadata changes.
Research Gate (Exa + arXiv — BOTH MANDATORY)

For new patterns, templates, or workflows, research is mandatory:

  1. Use Exa for implementation and ecosystem patterns:
    • mcp__Exa__web_search_exa({ query: '<topic> 2025 best practices' })
    • mcp__Exa__get_code_context_exa({ query: '<topic> implementation examples' })
  2. Search arXiv for academic research (mandatory for AI/ML, agents, evaluation, orchestration, memory/RAG, security):
    • Via Exa: mcp__Exa__web_search_exa({ query: 'site:arxiv.org <topic> 2024 2025' })
    • Direct API: WebFetch({ url: 'https://arxiv.org/search/?query=<topic>&searchtype=all&start=0' })
  3. Record decisions, constraints, and non-goals in artifact references/docs.
  4. Keep updates minimal and avoid overengineering.

arXiv is mandatory (not fallback) when topic involves: AI agents, LLM evaluation, orchestration, memory/RAG, security, static analysis, or any emerging methodology.

Regression-Safe Delivery
  • Follow strict RED -> GREEN -> REFACTOR for behavior changes.
  • Run targeted tests for changed modules.
  • Run lint/format on changed files.
  • Keep commits scoped by concern (logic/docs/generated artifacts).
