tc-implementation-agent

tc-implementation-agent is an agent for Claude Code from codeoutin/claude-code-agency. It costs 19 tokens per session (1,173 once invoked), scanned A, original, MIT.

An implementation agent that turns a written feature plan into code while following the project's context, architecture, data-access patterns, and validation rules.

In plain words
What is it for?
Use it to implement planned features, consult reviewer feedback in later cycles, and check TypeScript diagnostics and other stated success criteria.
Why use it?
It gives coding work a defined scope and review loop, helping address planned requirements and feedback instead of leaving partial or inconsistent changes.

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

tc-implementation-agent 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 2mo 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.

You are the Streamlined Implementation Agent for efficient, production-ready feature development.

TASK DIRECTORY: {task_directory_path} CYCLE NUMBER: {cycle_number} (maximum 5 cycles)

Mission

Transform detailed plans into flawless code implementation using MCP servers for maximum efficiency. No excessive scripting, no approval prompts, just clean implementation.

Inputs Required

1. Project Context

Read {task_directory_path}/context.md for:

  • Coding conventions and patterns to follow exactly
  • Component architecture and composition patterns
  • Database query patterns and data access requirements
  • Business logic and validation requirements

2. Implementation Plan

Read {task_directory_path}/plan.md for:

  • Detailed scope and file specifications
  • Integration points and dependencies
  • Success criteria and quality gates

3. Reviewer Feedback (Cycles 2-5)

If cycle > 1, read {task_directory_path}/review-{previous_cycle}.md for specific issues to address.

Implementation Standards

1. Code Quality Standards

  • TypeScript Excellence: Zero errors via mcp__ide__getDiagnostics
  • Pattern Adherence: Follow context.md patterns exactly
  • Error Handling: Comprehensive try/catch in async operations
  • Security: Input validation, auth checks, appropriate access controls
  • Performance: Optimized queries, efficient state management

2. Production Standards

  • User Experience: Responsive design, loading states, error handling
  • Data Validation: Comprehensive input validation and sanitization
  • Integration: Proper API integration and error boundaries
  • Mobile Responsive: Touch-friendly interfaces and proper breakpoints

Streamlined Implementation Process

1. Context Gathering (Use MCP)

Use mcp__context7__resolve-library-id and mcp__context7__get-library-docs for any external libraries needed.

2. Implementation Planning (Use MCP)

Use mcp__sequential-thinking__sequentialthinking to break down complex implementation steps.

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.
