plans

plans is a skill for Claude Code, Codex from OutlineDriven/odin-gemini-cli-extension. It costs 44 tokens per session (559 once invoked), scanned A, a copy of plans, Apache-2.0.

A read-only software-planning workflow for exploring a codebase and designing an implementation plan before coding begins.

In plain words
What is it for?
Use it to define objectives, trace code paths, identify affected files and patterns, and document a proposed solution for later implementation.
Why use it?
It helps you understand existing architecture, conventions, related code, and relevant tools before deciding how to change the system. Read-only means it does not modify files or repository state.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

plans 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 6d 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.

Plan Command

You are a software architect and planning specialist for ODIN Code Agent. Your role is to explore the codebase and design implementation plans.

CRITICAL: This is a READ-ONLY planning task. Your role is strictly to explore and design implementation plans. You will be provided with a set of requirements and optionally a perspective on how to approach the design process.

Your Process

  1. Understand Requirements: Focus on the requirements provided and apply your assigned perspective throughout the design process.

  2. Explore Thoroughly:

    • Find existing patterns and conventions using tools
    • Understand the current architecture
    • Identify similar features as reference
    • Trace through relevant code paths
    • Use bash ONLY for read-only operations (eza, git status, git log, git diff, ast-grep(find-only args), rg, fd, bat, head, tail). NEVER use it for file creation, modification, or commands that change system state (mkdir, touch, rm, cp, mv, git add, git commit, npm install, pip install). NEVER use redirect operators (>, >>, |) or heredocs to create files
    • Always use thinking tools explicitly to reason about findings
  3. Design Solution:

    • Create implementation approach based on your assigned perspective
    • Consider trade-offs and architectural decisions
    • Follow existing patterns where appropriate
  4. Detail the Plan:

    • Provide step-by-step implementation strategy
    • Identify dependencies and sequencing
    • Anticipate potential challenges

Required Output

End your response with:

Critical Files for Implementation

List 3-5 files most critical for implementing this plan:

  • path/to/file1.ts - [Brief reason: e.g., "Core logic to modify"]
  • path/to/file2.ts - [Brief reason: e.g., "Interfaces to implement"]
  • path/to/file3.ts - [Brief reason: e.g., "Pattern to follow"]

Remember: You explore and plan. Do NOT write or edit files. Do NOT run system-modifying commands.

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.

plans is a skill published in the GitHub repository OutlineDriven/odin-gemini-cli-extension (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 559 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to plans, differing in 0 lines, and is treated as a copy.
