Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00005 | $0.00569 |
| Opus 5.5 | $0.00002 | $0.00228 |
| Sonnet 5.5 | $0.00001 | $0.00114 |
| Haiku 4.5 | $0.00001 | $0.00057 |
Grade A, and why
create-command scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Phase 1: Skill Requirements Extraction (BLOCKING)
Read these files NOW before proceeding:
${CLAUDE_PLUGIN_ROOT}/skills/command-development/SKILL.md${CLAUDE_PLUGIN_ROOT}/skills/command-development/references/testing-strategies.md
After reading, output a Requirements Summary with these exact sections:
Frontmatter Fields
| Field | Purpose | Valid Values |
|---|---|---|
| [extract each field from skill] |
Argument Syntax Rules
- $ARGUMENTS: [when/how to use]
- Positional ($1, $2): [when/how to use]
- argument-hint: [format requirement]
File Reference Syntax
- @ syntax: [correct usage]
- Static vs dynamic: [difference]
Bash Execution Syntax
- Inline execution syntax: [exact format from skill]
- allowed-tools requirement: [pattern]
Command Location Rules
- Project commands: [path]
- Personal commands: [path]
- Plugin commands: [path]
Anti-Patterns (from "Critical: Commands are Instructions FOR Claude")
- Incorrect approach: [what to avoid]
- Correct approach: [what to do]
Do not proceed until this summary is complete with skill-specific content.
Phase 2: Command Specification
Command name: Purpose: Location: [project/personal/plugin] Arguments (if any): Tools needed (if any): File references (if any):
Phase 3: Implementation
Create the command file applying ALL requirements from Phase 1.
Phase 4: Testing Plan (from testing-strategies.md)
Generate a testing checklist for this specific command:
Level 1-2: Structural Validation
# [generate validation commands for this command]
Level 4: Argument Testing
| Test Case | Command | Expected |
|---|---|---|
| [generate test matrix for this command's arguments] |
Edge Cases
- [list 3-5 edge cases specific to this command]
Phase 5: Self-Verification
| Skill Requirement | Implemented? | Evidence |
|---|---|---|
| Instructions written FOR Claude (not TO user) | ||
| description < 60 chars | ||
| argument-hint matches actual arguments | ||
| allowed-tools if bash used | ||
| @ syntax correct for file refs | ||
| Single responsibility |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

create-command is a command published in the GitHub repository basher83/lunar-claude (23 stars, last pushed today), licensed MIT. It adds 5 tokens to every session and 569 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
