Implement a story according to the requirements and tasks is a skill for Claude Code from Intai/story-flow. It costs 17 tokens per session (615 once invoked), scanned A, original, MIT.

An orchestration skill for implementing a software story from its requirements and tasks. It assigns the work to separate agents and coordinates their results.

In plain words
What is it for?
Implementing story tasks, grouping work by dependencies, delegating coding jobs, and checking that the resulting changes meet the stated requirements.
Why use it?
It divides dependent work among agents and requires testing, coverage, linting, and visual checks where the instructions call for them.

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 a story according to the requirements and tasks 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 9d 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 a story according to the requirements and tasks

Instructions

  • The story should have tasks grouped by dependencies using the format from story-flow:analyze-task-dependencies skill.
  • You are an orchestrator, not an implementer.
    • REQUIRED: Immediately delegate ALL tasks to subagents using the Task tool to run them in isolated context.
    • FORBIDDEN tools for orchestrator (NEVER use directly):
      • Glob, Grep, Read
      • Write, Edit, MultiEdit
      • WebSearch, WebFetch
      • TaskCreate, TaskUpdate, TaskGet, TaskList
      • Task with Explore subagent
  • Instruct each subagent:
    • When installing dependencies, use the latest stable version, or a higher patch version within the existing minor if the project pins one.
    • After implementing UI according to UI design HTML files, verify by taking screenshots of both the UI and the design using mcp__plugin_story-flow_chrome-devtools__navigate_page and mcp__plugin_story-flow_chrome-devtools__take_screenshot.
    • For every source file created or modified, update the corresponding test file to achieve 100% coverage and ensure all linting warnings and errors are resolved.
      • One test case per scenario/behavior, not one test per assertion.
      • Combine test assertions for basic rendering into a single test - only separate tests when testing different states, behaviors, or edge cases.
      • Every test must have assertions that verify the behavior described in its test name — not just that the code runs without crashing.
        • No missing assertions: every test must contain at least one expect() that checks a meaningful outcome.
        • Assertions must be correct: expected values must match the actual business logic, not be copied from implementation output without verification.
    • Report back to the orchestrator just "completed" or "failed". On success, strictly nothing else. On failure, include a brief summary of the issues encountered.
  • When a story references the qa-tester subagent for planning BDD scenarios, use the qa-tester subagent and instruct it to load BOTH skills in this order using the Skill tool:
    1. First: story-flow:plan-bdd-scenarios (plugin - general BDD planning protocol)
    2. Then: plan-bdd-scenarios (project-level - overrides/extends the plugin)
    3. Confirm both skills are loaded before continuing with BDD planning.

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.
