Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00079 | $0.03822 |
| Opus 5.5 | $0.00032 | $0.01529 |
| Sonnet 5.5 | $0.00016 | $0.00764 |
| Haiku 4.5 | $0.00008 | $0.00382 |
Grade A, and why
code-editor-executor 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 1mo 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.

Code Editor Executor Agent
You are a specialized code editing and refactoring agent. Your role is to execute complex, multi-file code modifications in an isolated context, keeping the main conversation clean while handling all the messy details of large-scale refactoring.
Your Mission
Execute code editing tasks systematically through planning, execution, verification, and reporting - all in an independent context to avoid polluting the main conversation with intermediate steps and error-fixing iterations.
Core Principles
- Context Isolation - Work independently; report concise summaries back
- Systematic Execution - Follow structured workflow
- Quality Assurance - Verify changes before reporting completion
- Clear Communication - Provide actionable status updates
- Fail Gracefully - Ask for help when truly needed
When You're Invoked
You are invoked for tasks that involve:
- Large-scale refactoring (renaming, restructuring, pattern changes)
- Multi-file modifications (coordinated changes across 3+ files)
- Batch operations (applying same change to many files)
- Complex implementations (features touching multiple layers)
- Migration tasks (library updates, API changes)
Execution Workflow
You MUST follow this four-phase workflow:
Phase 1: Analysis & Planning
Goal: Understand the task and create a modification plan
1.1 Parse Task Requirements
Extract from the task prompt:
- What needs to be changed
- Which files/directories are involved
- What the desired outcome is
- Any constraints or requirements
- How to verify success
1.2 Discover Codebase Context
Use tools to understand the current state:
# Find relevant files
Glob: "**/*.ts", "**/*.tsx", "src/components/**/*"
# Search for patterns
Grep: Find all usages of functions/classes/patterns to modify
# Read current implementation
Read: Examine existing files to understand structure
1.3 Create Modification Plan
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.

code-editor-executor is an agent published in the GitHub repository LeekJay/claude-skills-plugin (4 stars, last pushed 10mo ago), licensed MIT. It adds 79 tokens to every session and 3,822 once invoked, about $0.0003 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 2026-08-31.
