implement_plan

implement_plan is a skill for Claude Code from parcadei/Continuous-Claude-v3. It costs 13 tokens per session (2,374 once invoked), scanned A, original, MIT.

A workflow for carrying out an approved technical plan stored in a project folder, one phase at a time, with checks that confirm the work is complete.

In plain words
What is it for?
Use it to implement small or multi-phase engineering plans, including plans that are split among helper agents and passed between them.
Why use it?
It turns a written plan into concrete code changes and keeps track of progress, reducing missed steps and unverified work.

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

implement_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 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.

Implement Plan

You are tasked with implementing an approved technical plan from thoughts/shared/plans/. These plans contain phases with specific changes and success criteria.

Execution Modes

You have two execution modes:

Mode 1: Direct Implementation (Default)

For small plans (3 or fewer tasks) or when user requests direct implementation.

  • You implement each phase yourself
  • Context accumulates in main conversation
  • Use this for quick, focused implementations

Mode 2: Agent Orchestration (Recommended for larger plans)

For plans with 4+ tasks or when context preservation is critical.

  • You act as a thin orchestrator
  • Agents execute each task and create handoffs
  • Compaction-resistant: handoffs persist even if context compacts
  • Use this for multi-phase implementations

To use agent orchestration mode, say: "I'll use agent orchestration for this plan" and follow the Agent Orchestration section below.


Getting Started

When given a plan path:

  • Read the plan completely and check for any existing checkmarks (- [x])
  • Read the original ticket and all files mentioned in the plan
  • Read files fully - never use limit/offset parameters, you need complete context
  • Think deeply about how the pieces fit together
  • Create a todo list to track your progress

Pre-Implementation Risk Check

Before starting implementation, run a deep pre-mortem:

/premortem deep <plan-path>

This analyzes the plan against comprehensive checklists:

  • Technical risks (scalability, dependencies, data, security)
  • Integration risks (breaking changes, migration, rollback)
  • Process risks (unclear requirements, stakeholder input)
  • Testing risks (coverage gaps, load testing needs)

If HIGH severity risks are identified:

  • The premortem will block via AskUserQuestion
  • User must: accept risks explicitly, add mitigations, or research solutions
  • If mitigations are added, update the plan before proceeding

Skip premortem if:

  • Plan already has a "## Risks (Pre-Mortem)" section with mitigations
  • User explicitly requests to skip (--skip-premortem)

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
