Development Workflow

scope-triage is the development entry point. It classifies the request and picks the minimum appropriate process, so a one-line configuration change and a new subsystem do not receive the same ceremony.

    S[scope-triage] --> R{Route}

    R -->|A: Direct| D[Direct implementation]
    R -->|B: Light spec| L[Light spec]
    L --> D

    R -->|C: Full design| F[Approved design]
    F --> P[plan-crafting]

    P --> E{Execution mode}
    E --> I[inline-plan-dev]
    E --> SA[subagent-plan-dev]

    D -. behavior changes .-> T[tdd]
    I -. behavior changes .-> T
    SA -. behavior changes .-> T

    D --> Q{Review warranted?}
    I --> Q
    SA --> Q

    Q -->|Yes| RR[review-request]
    RR --> RF{Findings?}
    RF -->|Yes| RES[review-resolution]
    RF -->|No| V[verification-gate]
    RES --> V

    Q -->|No| V

    V -->|PASS| B{Branch/workspace lifecycle?}
    B -->|Yes| BF[branch-finish]
    B -->|No| DONE[Complete]

    BF --> DONE

When work fails unexpectedly, the diagnostic path runs alongside the main flow and returns to whatever workflow discovered the failure.

    F[Unexpected failure / bug / regression] --> D[debugging]

    D --> W{Browser evidence needed?}
    W -->|Yes| WD[web-debug]
    WD --> D

    W -->|No or evidence sufficient| RC{Root cause established?}

    RC -->|No| D
    RC -->|Yes| B{Behavior correction?}

    B -->|Yes| T[tdd]
    B -->|No| FIX[Root-cause fix]

    T --> FIX

    FIX --> RET[Return to calling workflow]

    D -. material redesign required .-> S[scope-triage]

Four properties of this workflow are worth stating explicitly.

• tdd is used within implementation, whenever behavior changes. It is a micro-cycle inside a task rather than a sequential phase that follows implementation. Both execution modes and direct implementation invoke it at the moment a behavior change is written.
• Review is proportional; verification is authoritative. review-request is invoked when the change warrants independent eyes, and review-resolution validates findings before anything is changed in response. A review verdict stands separate from completion: verification-gate owns the authoritative pass or fail against the current tree.
• The diagnostic path has three distinct owners. debugging owns causal investigation, web-debug supplies browser and runtime evidence when the symptom lives in a page, and tdd drives the regression behavior once the cause is known. The fix then returns to the workflow that discovered the failure.
• The workflow is composable rather than mandatory-linear. Every step after scope-triage is reached on a condition. Route A terminates in implementation with proportional verification, and branch-finish runs only when a branch or workspace lifecycle exists.

Conditional capabilities, invoked when the work calls for them rather than in sequence: tdd, debugging, web-debug, git-worktree-isolation, parallel-agents, frontend-crafting, vitest, typescript, echarts.

Debugging

Skill	Skill Version	Release	Description
debugging	1.0.9	v1.33.1	Investigate bugs and unexpected technical behavior with a root-cause-first evidence workflow.
web-debug	1.3.3	v1.26.0	Debug and verify local web apps via Playwright.

Review & Verification

Skill	Skill Version	Release	Description
review-request	1.0.3	v1.27.0	Prepare and dispatch independent code review against requirements, exact scope, and the actual diff.

echarts	1.2.1	v1.22.0	Build, audit, style, debug, and optimize Apache ECharts visualizations in vanilla JS, React, or Vue.

TypeScript & Testing

Writing Style

Skill	Skill Version	Release	Description
dashfix	1.2.2	v1.12.1	Ban typographic dashes in English text, check their form where a language's orthography requires them, audit a project, and score it 0-100.
negafix	1.2.2	v1.12.1	Ban negative parallelism ("it's not just X, it's Y"), audit prose for it, and score it 0-100.

Have fun ;)
