name: pydev-workflow description: comprehensive 12-step project development workflow from initialization through deployment. use when starting a new project, continuing project development, or user mentions project steps, architecture planning, implementation planning, or references pydev-workflow steps 01-12. allowed-tools: Read, Glob, Grep, Write, Edit, Bash(git:), Bash(pytest:), Bash(alembic:), Bash(npm:)

pydev-workflow: Project-Level Development Workflow

execute 12-step structured development process for complete project implementation.

when to apply this skill

• user says "initialize pydev-workflow" or "start pydev-workflow"
• user says "continue pydev-workflow" or "resume project"
• user asks about project status, current step, or workflow progress
• user mentions specific step numbers (01-12) or step names (project-init, system-architecture, etc.)
• user requests architecture design, implementation planning, or deployment prep
• project has PROJECT_FOUNDATION.md, ARCHITECTURE.md, or IMPLEMENTATION_PLAN.md files

workflow entry points

can start at any step based on context:

core principles

always read CLAUDE.md first

check project root for CLAUDE.md - contains project-specific best practices, patterns, and context.

80% certainty rule

• above 80% certain: execute autonomously, document decisions
• below 80% certain: stop, explain uncertainty, ask specific questions

git requirements

• email: isa.lucia.sch@gmail.com
• user: luvisaisa
• branch: main
• commit frequently: after meaningful changes per commit triggers table

documentation practices

• update existing files, do not create new ones without evaluation
• timestamp all documentation updates: > Last updated: [YYYY-MM-DD]
• use mermaid.js for all diagrams
• maintain DEV_LOG.md with implementation summaries
• comments always lowercase, no emojis

12-step workflow

resuming workflow

when user says "continue workflow" or "resume":

1. check for existing documentation:

   Copyls -la PROJECT_FOUNDATION.md ARCHITECTURE.md IMPLEMENTATION_PLAN.md TEST_STRATEGY.md DEV_LOG.md
   

2. determine current step based on what exists:

   • PROJECT_FOUNDATION.md only → at step 02
   • ARCHITECTURE.md exists → check completeness (sections), proceed to next incomplete
   • IMPLEMENTATION_PLAN.md exists → at step 07 (implementation)
   • implementation complete but no TEST_STRATEGY.md → at step 08
   • TEST_STRATEGY.md exists → at step 09 or 10

3. read CLAUDE.md for current status if exists

4. read DEV_LOG.md for recent activity

5. report current status:

   Copy[pydev-workflow STATUS]
   
   current step: [step number and name]
   completed: [list of completed steps]
   in progress: [current work]
   next: [what comes next]
   

6. ask user to confirm or adjust direction

context-aware execution

analyze user messages for context clues:

progress tracking format

Copy[pydev-workflow PROGRESS]

✅ 01: project initialization - PROJECT_FOUNDATION.md created
✅ 02: system architecture - ARCHITECTURE.md with components
✅ 03: data models - added to ARCHITECTURE.md
✅ 04: core logic - added to ARCHITECTURE.md
🔄 05: interface design - in progress
⏸️  06: implementation plan - pending
⏸️  07: implementation - pending
⏸️  08: test strategy - pending
⏸️  09: test implementation - pending
⏸️  10: integration - pending
⏸️  11: documentation - pending
⏸️  12: deployment - pending

integration with pydev-feature

during step 07 (implementation), invoke pydev-feature skill for each implementation unit:

Copy[invoking pydev-feature for unit: [unit name]]

unit todo:
* major task: [goal]
   * mid-level task: [deliverable]
      * minor task: [action]

[pydev-feature will handle task-analysis through cleanup]
[returns when unit complete]

[updating IMPLEMENTATION_PLAN.md progress]
