kanban-mcp: Skill for Claude Code

.claude/skills/kanban-sprint/SKILL.md

kanban-sprint is a skill for Claude Code from SimonBlancoE/kanban-mcp. It costs 30 tokens per session (1,974 once invoked), scanned A, original, MIT.

An orchestrator for a complete Kanban development cycle involving planning, implementation, and quality review.

In plain words
What is it for?
Use it to run a feature from planning through execution and review, with named specialist agents and repeated refinement when needed.
Why use it?
It coordinates Architect, Agent, and QA roles and can send rejected work back for another iteration until it passes review or reaches the limit.

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

kanban-sprint 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 10d 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.

Kanban Sprint - Ralph Wiggum Full Development Cycle

You are running a Sprint - a full development cycle that orchestrates Architect, Agent, and QA roles with iterative refinement (Ralph Wiggum pattern) and session tracking for cross-context-window continuity.

Arguments

Optional task/feature description after the command. Example: /kanban-sprint implement user authentication

Agent Naming

IMPORTANT: Use descriptive agent names based on task specialization, NOT generic names.

Good examples:

  • frontend-specialist - For UI/React/CSS work
  • backend-engineer - For API/database work
  • test-writer - For test coverage
  • security-reviewer - For security tasks
  • devops-agent - For infrastructure work

Bad examples (too generic):

  • agent-alpha, agent-beta, agent-gamma

Sprint Lifecycle

PLANNING -> EXECUTING -> REVIEWING -> COMPLETE/FAILED
             ^    |
             |    v (if rejections)
             +----+

A sprint can have multiple iterations. Each iteration:

  1. Agents work on tasks
  2. QA reviews
  3. If rejections, loop back (up to maxIterations)

Execution Instructions

Phase 0: Session Start & Learning Context

Start a session and get project insights:

kanban_session_start with agentId: "sprint-orchestrator"

This returns:

  • Board state and recent activity
  • Last session notes for continuity
  • Urgent items (escalated, blocked, critical)
  • Learning context

Also get detailed learning insights:

kanban_get_learning_insights with role: "architect"

Review:

  • Past project lessons
  • Codebase conventions
  • Common patterns to follow

Phase 1: Planning

Create the sprint first:

kanban_sprint_create:
  role: "architect"
  goal: "[User's goal description]"
  successCriteria:
    - "Criterion 1"
    - "Criterion 2"
    - "All tests pass"
  maxIterations: 5

Generate a summary for sub-agents:

kanban_generate_summary

Then spawn an Architect agent:

Task tool:
  subagent_type: "general-purpose"
  description: "Architect planning sprint"
  prompt: |
    You are the ARCHITECT for Kanban sprint [SPRINT_ID].

    GOAL: [User's goal]

    1. Start session: kanban_session_start with agentId: "architect"
    2. Get learning insights: kanban_get_learning_insights
    3. Analyze the codebase to understand patterns
    4. Create 3-8 tasks using kanban_create_task with:
       - role: "architect"
       - sprintId: "[SPRINT_ID]"
       - acceptanceCriteria: { description, verificationSteps, testCommand }
       - maxIterations: 3
    5. Set priorities and dependencies
    6. Assign tasks to descriptive agent names based on task type:
       - frontend-specialist (UI/React work)
       - backend-engineer (API/database work)
       - test-writer (test coverage)
       - Or other descriptive names matching the task domain
    7. End session: kanban_session_end with sessionNotes

    IMPORTANT: Each task must have clear acceptance criteria!
    IMPORTANT: Use descriptive agent names, NOT generic names like agent-alpha!

    Report: tasks created with their acceptance criteria and agent assignments.

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.
