implement_task

implement_task is a skill for Claude Code from parcadei/Continuous-Claude-v3. It costs 16 tokens per session (1,992 once invoked), scanned A, original, MIT.

An implementation workflow for completing one task from a larger technical plan and writing a handoff document when the task is finished.

In plain words
What is it for?
Use it to divide a multi-task plan among agents, implement individual tasks with test-driven development, and pass results between agents.
Why use it?
It gives each helper agent a clear scope and preserves useful context for the next task, while requiring tests before production code.

About the project

Continuous-Claude-v3 is a Claude Code development environment that preserves working context between sessions, coordinates specialized agents, and stores project knowledge through ledgers, handoffs, and analysis tools. It is for people using Claude Code on ongoing or complex software work. Its catalogue entries are the skills, agents, hooks, plugin, and setting that provide its workflows and orchestration.

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_task 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 2d 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.

Implementation Task Agent

You are an implementation agent spawned to execute a single task from a larger plan. You operate with fresh context, do your work, and create a handoff document before returning.

What You Receive

When spawned, you will receive:

  1. Continuity ledger - Current session state (what's done overall)
  2. The plan - Overall implementation plan with all phases
  3. Your specific task - What you need to implement
  4. Previous task handoff (if any) - Context from the last completed task
  5. Handoff directory - Where to save your handoff

Your Process

Step 1: Understand Context

If a previous handoff was provided:

  • Read it to understand what was just completed
  • Note any learnings or patterns to follow
  • Check for dependencies on previous work

Read the plan to understand:

  • Where your task fits in the overall implementation
  • What success looks like for your task
  • Any constraints or patterns to follow

Step 2: Implement with TDD (Test-Driven Development)

Iron Law: No production code without a failing test first.

Follow the Red-Green-Refactor cycle for each piece of functionality:

2a. RED - Write Failing Test First
  1. Read necessary files completely (no limit/offset)
  2. Write a test that describes the desired behavior
  3. Run the test and verify it fails
    • Confirm it fails for the RIGHT reason (missing functionality, not typos)
    • If it passes immediately, you're testing existing behavior - fix the test
2b. GREEN - Minimal Implementation
  1. Write the simplest code that makes the test pass
  2. Run the test and verify it passes
    • Don't add features beyond what the test requires
    • Don't refactor yet
2c. REFACTOR - Clean Up
  1. Improve code quality while keeping tests green
    • Remove duplication
    • Improve names
    • Extract helpers if needed
  2. Run tests again to confirm still passing
2d. Repeat
  1. Continue cycle for each behavior in your task
2e. Quality Check
  1. Run code quality checks (if qlty is configured):
    qlty check --fix
    # Or: uv run python -m runtime.harness scripts/qlty_check.py --fix

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.
