execute-task

A command for carrying out one development task described in a task-breakdown file. It reads the task's requirements, acceptance checks, referenced files, and existing code patterns before implementation.

In plain words
What is it for?
Use it to implement a specific task from docs/tasks/, follow Given-When-Then acceptance scenarios, and fit the change to existing code conventions.
Why use it?
It reduces the risk of missing requirements or coding against the wrong parts of a project. It also turns a broad task document into a focused implementation plan.

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

execute-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.

Execute Development Task

Implement a specific development task using the detailed task specification.

Task File: $ARGUMENTS

Execution Process

  1. Load Task Document

    • Read the specified task breakdown file from docs/tasks/
    • Understand task context, requirements, and acceptance criteria
    • Review all referenced files and code patterns
    • Load the comprehensive task template structure
    • Identify specific task within document if multiple tasks present
  2. Task Analysis

    • Extract the specific task requirements and constraints
    • Review Given-When-Then acceptance criteria scenarios
    • Study referenced code patterns and file locations
    • Understand integration points and dependencies
  3. Implementation Planning

    • Use TodoWrite tool to create focused implementation plan
    • Break down the single task into micro-steps if needed
    • CRITICAL: Study all referenced files specified in task description
    • PATTERN MATCHING: Identify exact patterns to mirror from existing code
    • Plan implementation approach following established conventions
  4. Focused Implementation

    • BEFORE coding: Read reference files to understand exact structure
    • MIRROR PATTERNS: Follow existing code patterns exactly
    • Implement only the specific task requirements (no scope creep)
    • Apply error handling patterns from reference implementations
    • Follow code organization and naming conventions from examples
  5. Acceptance Criteria Validation

    • Execute each Given-When-Then scenario manually
    • Verify rule-based criteria checklist completion
    • Execute validation commands specified in task
  6. Quality Gates

    • Run project-specific validation commands
    • Fix any linting, type-checking, or build errors
    • Ensure task-specific Definition of Done criteria met
    • Verify integration with existing systems
  7. Task Completion

    • Mark task as completed in TodoWrite
    • Verify all acceptance criteria satisfied
    • Document any implementation notes or gotchas discovered
    • Report completion status with validation results

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.

execute-task is a command published in the GitHub repository croffasia/cc-blueprint-toolkit (194 stars, last pushed 9mo ago), licensed MIT. It adds 8 tokens to every session and 551 once invoked, about $0.0000 per session on Opus 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.
