create-implementation-plan

create-implementation-plan is a skill for Claude Code, Codex from GulajavaMinistudio/awesome-copilot-id. It costs 29 tokens per session (1,418 once invoked), scanned A, a copy of create-implementation-plan, MIT.

A workflow for creating an implementation-plan file for software features, refactoring, package upgrades, design, architecture, or infrastructure changes. It structures work into discrete phases with completion criteria.

In plain words
What is it for?
Use it to write machine-readable plans that break a change into executable tasks and state when each phase is complete.
Why use it?
It reduces ambiguity by making the intended work and its definition of done explicit for people or coding agents.

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

create-implementation-plan 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 12d 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.

Create Implementation Plan

Primary Directive

Your goal is to create a new implementation plan file for ${input:PlanPurpose}. Your output must be machine-readable, deterministic, and structured for autonomous execution by other AI systems or humans.

Execution Context

This prompt is designed for AI-to-AI communication and automated processing. All instructions must be interpreted literally and executed systematically without human interpretation or clarification.

Core Requirements

  • Generate implementation plans that are fully executable by AI agents or humans
  • Use deterministic language with zero ambiguity
  • Structure all content for automated parsing and execution
  • Ensure complete self-containment with no external dependencies for understanding

Plan Structure Requirements

Plans must consist of discrete, atomic phases containing executable tasks. Each phase must be independently processable by AI agents or humans without cross-phase dependencies unless explicitly declared.

Phase Architecture

  • Each phase must have measurable completion criteria
  • Tasks within phases must be executable in parallel unless dependencies are specified
  • All task descriptions must include specific file paths, function names, and exact implementation details
  • No task should require human interpretation or decision-making

AI-Optimized Implementation Standards

  • Use explicit, unambiguous language with zero interpretation required
  • Structure all content as machine-parseable formats (tables, lists, structured data)
  • Include specific file paths, line numbers, and exact code references where applicable
  • Define all variables, constants, and configuration values explicitly
  • Provide complete context within each task description
  • Use standardized prefixes for all identifiers (REQ-, TASK-, etc.)
  • Include validation criteria that can be automatically verified

Output File Specifications

  • Save implementation plan files in /plan/ directory
  • Use naming convention: [purpose]-[component]-[version].md
  • Purpose prefixes: upgrade|refactor|feature|data|infrastructure|process|architecture|design
  • Example: upgrade-system-command-4.md, feature-auth-module-1.md
  • File must be valid Markdown with proper front matter structure

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-implementation-plan is a skill published in the GitHub repository GulajavaMinistudio/awesome-copilot-id (73 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 1,418 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to create-implementation-plan, differing in 22 lines, and is treated as a copy.
