tool-filter-mcp: Command for Claude Code

.claude/commands/implement.md

implement is a command for Claude Code from respawn-llc/tool-filter-mcp. It costs 14 tokens per session (661 once invoked), scanned A, original, MIT.

An implementation command that reads a project's task list and supporting design documents, then carries out the planned software work. It follows task phases, dependencies, file paths, and parallel-work markers.

In plain words
What is it for?
Use it to execute tasks from tasks.md, consult the plan and related specifications, and work through setup, testing, core, integration, and polishing phases.
Why use it?
It gives an agent a defined execution order and the context needed to implement planned changes consistently.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is respawn-llc/tool-filter-mcp's own configuration. It tells Claude Code how to work on tool-filter-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything tool-filter-mcp configures →

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 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 1mo 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.

What it actually says

The user input can be provided directly by the agent or as a command argument - you MUST consider it before proceeding with the prompt (if not empty).

User input:

$ARGUMENTS

  1. Run .specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute.

  2. Load and analyze the implementation context:

    • REQUIRED: Read tasks.md for the complete task list and execution plan
    • REQUIRED: Read plan.md for tech stack, architecture, and file structure
    • IF EXISTS: Read data-model.md for entities and relationships
    • IF EXISTS: Read contracts/ for API specifications and test requirements
    • IF EXISTS: Read research.md for technical decisions and constraints
    • IF EXISTS: Read quickstart.md for integration scenarios
  3. Parse tasks.md structure and extract:

    • Task phases: Setup, Tests, Core, Integration, Polish
    • Task dependencies: Sequential vs parallel execution rules
    • Task details: ID, description, file paths, parallel markers [P]
    • Execution flow: Order and dependency requirements
  4. Execute implementation following the task plan:

    • Phase-by-phase execution: Complete each phase before moving to the next
    • Respect dependencies: Run sequential tasks in order, parallel tasks [P] can run together
    • Follow TDD approach: Execute test tasks before their corresponding implementation tasks
    • File-based coordination: Tasks affecting the same files must run sequentially
    • Validation checkpoints: Verify each phase completion before proceeding
  5. Implementation execution rules:

    • Setup first: Initialize project structure, dependencies, configuration
    • Tests before code: If you need to write tests for contracts, entities, and integration scenarios
    • Core development: Implement models, services, CLI commands, endpoints
    • Integration work: Database connections, middleware, logging, external services
    • Polish and validation: Unit tests, performance optimization, documentation
  6. Progress tracking and error handling:

    • Report progress after each completed task
    • Halt execution if any non-parallel task fails
    • For parallel tasks [P], continue with successful tasks, report failed ones
    • Provide clear error messages with context for debugging
    • Suggest next steps if implementation cannot proceed
    • IMPORTANT For completed tasks, make sure to mark the task off as [X] in the tasks file.
  7. Completion validation:

    • Verify all required tasks are completed
    • Check that implemented features match the original specification
    • Validate that tests pass and coverage meets requirements
    • Confirm the implementation follows the technical plan
    • Report final status with summary of completed work

Note: This command assumes a complete task breakdown exists in tasks.md. If tasks are incomplete or missing, suggest running /tasks first to regenerate the task list.

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.

implement is a command published in the GitHub repository respawn-llc/tool-filter-mcp (36 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 661 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
