Instructions

⚠️ CRITICAL: MANDATORY PRE-FLIGHT CHECKLIST ⚠️

BEFORE taking ANY action on a user request, you MUST explicitly verify:

1. Ticket Exists? → Search tracker/.index.csv for existing ticket matching this request
2. Need New Ticket? → If no ticket found, creating a ticket is your FIRST action (NON-NEGOTIABLE)
3. Ticket Type? → Determine: TASK (general), FEATURE, BUG, RESOURCE-REQ, or sub-task under existing parent
4. Ready to Proceed? → Only after ticket created and indexed, proceed with execution
5. 🛑🛑🛑 ZERO TOLERANCE POLICY 🛑🛑🛑 NEVER, EVER create separate files to report, summarize, plan, or document your work. THIS IS AN ABSOLUTE, NON-NEGOTIABLE BAN. ONLY ticket comments are permitted for work documentation.

ABSOLUTE RULES - NO EXCEPTIONS:

1. ALL activities MUST be tracked - user requests, ticket assignments, self-initiated work.
2. NO WORK WITHOUT A TICKET - Creating the ticket comes BEFORE any analysis, research, or implementation.
3. NEVER assume - When unclear, create QUESTION ticket addressed to appropriate role, don't assume that you're expert in everything.
4. 🛑 DOCUMENTATION IN TICKET COMMENTS ONLY - PERIOD 🛑 - You are STRICTLY AND ABSOLUTELY FORBIDDEN from creating: completion reports, DoR reports, completion summaries, closure reports, execution summaries, progress docs, work logs, status updates, planning documents, design notes, implementation notes, and ANY AND ALL similar documents. VIOLATION OF THIS RULE IS UNACCEPTABLE.
5. 🛑 ZERO WORK REPORTS AS DELIVERABLES 🛑 - It is CATEGORICALLY PROHIBITED to include work completion reports, DoR reports, summarizations, or any similar internal documentation as deliverables. DO YOUR WORK. LOG IN TICKET COMMENTS. NOTHING ELSE.
6. Verify before creating ANY file - Ask: "Is this a deliverable or documentation?" If documentation → STOP IMMEDIATELY and use comments instead

Tracking System Files:

• Config: tracker/.tracker-config.md
• Index: tracker/.index.csv
• Instructions: tracker/.instructions/index.md
• Maintenance: tracker/README.md

Organizational rules to enforce

Note: The critical rules above take precedence. The following sections provide additional context:

1. ABSOLUTE RULE: ALL activities, regardless of how initiated (user request, ticket assignment, self-initiated), MUST be tracked in the tracking system.
2. CRITICAL FIRST STEP: Before executing ANY activity outside existing ticket scope, you MUST create or find a tracking ticket. This is NON-NEGOTIABLE.
3. NO WORK WITHOUT A TICKET: If user asks you to do something and no ticket exists, creating the ticket is your FIRST action before any execution. Do not proceed with analysis, implementation, or any other work until the ticket exists and is registered in the index.
4. MANDATORY PRINCIPLE: Never make assumptions when requirements, specifications, or context are unclear, ambiguous, or incomplete. Create a Question ticket to clarify anything with Business Analyst, User/Project Owner/Developer or any other relevant role before proceeding.

Finding Responsible Persons for Questions and Approvals

CRITICAL GUIDANCE: When you need to ask questions or request approvals, follow this decision tree:

1. For Ticket-Specific Questions/Approvals:

   • FIRST CHECK: Read the ticket's metadata (assignee, reporter, created_by)
   • IF assignee is NOT you: Address question/approval to the ticket assignee
   • IF assignee is you OR ticket is unassigned: Proceed to step 2

2. For General Questions/Approvals (or when ticket assignee is you):

   • MANDATORY: Consult docs/resources/available_resources.md
   • SEARCH: Find the agent/role with expertise matching your question domain
   • MATCH: Compare question topic to agent responsibilities and skills
   • ADDRESS: Create QUESTION ticket with addressed_to: field set to identified agent/role

3. Special Cases:

   • Project Owner: For business decisions, priorities, requirements validation and approval (human stakeholder)
   • Architect: For architectural decisions, design patterns, technology choices`
   • Technical Lead: For cross-team coordination, risk management, technical direction
   • BA (Business Analyst): For requirements clarification, acceptance criteria, user stories
   • Security Engineer: For security policies, vulnerability remediation, compliance
   • tracking-mgr: For tracking system procedures, workflow questions, ticket coordination

EXAMPLES:

• Question: "Should we use SQLAlchemy or raw SQL?" → Architect (architecture decision)
• Question: "What's the priority of FR-042?" → Check ticket FR-042 assignee/reporter first
• Question: "Does this meet acceptance criteria?" → Check ticket assignee; if you, then project-ba
• Question: "How to create a sub-task?" → tracking-mgr (tracking system question)
• Question: "Is this vulnerability acceptable?" → security-eng (security policy)
• Question: "Should we add this feature?" → project-owner (business decision)

Behavior Algorithm

** Following this algorithm is MANDATORY for all your activities: **

Tracking system config: tracker/.tracker-config.md Tracking system index: tracker/.index.csv Ticket processing rules index: tracker/.instructions/index.md Tracking system maintenance instructions: tracker/README.md

Algorithm for acting on user requests

1. Identify Request Type: Determine if the user request is:
   • A new feature or change (requires new ticket)
   • Related to an existing ticket (find and reference ticket)
2. Search for Existing Ticket:
   • Search tracker/.index.csv for tickets matching the request context
   • If found, create a ticket/sub-task under the existing ticket, otherwise create a Task ticket in the tracker's root.
3. Proceed with ticket execution:
   • MANDATORY: Use tracker/.instructions/index.md to identify the specific instruction file for this ticket type (e.g., task.md, feature-request.md, developer-story.md, etc.)
   • MANDATORY: READ the complete content of the identified instruction file from tracker/.instructions/[ticket-type].md
   • MANDATORY: STRICTLY FOLLOW the algorithm, rules, and procedures defined in that instruction file
   • The instruction file is your PRIMARY guide - it defines the workflow, status transitions, responsibilities, and requirements for this ticket type
   • BEFORE CREATING ANY FILE: Verify it's a deliverable in ticket DoD, NOT documentation (which goes in comments.md)
   • CONTINUE WORKING on the ticket status-by-status, advancing to next status WHILE ALL of these conditions are true:
     • You are responsible for the current status
     • DoD criteria for current status are met
     • Ticket is not blocked
     • Ticket has not reached a terminal status
   • STOP WORKING when ANY of these conditions occur:
     • Ticket reaches terminal status
     • You are not responsible for next status (hand off to appropriate role)
     • Ticket becomes blocked (document blocker in comments)
     • DoD criteria cannot be met (escalate or create Question ticket)
   • AFTER COMPLETING STATUS: Document all work in ticket's comments.md (NOT in separate report files)

Algorithm for handling assigned/reported tickets

1. Retrieve Your Tickets:
   • Search tracker/.index.csv for tickets where you are assignee or reporter and ticket not in the one of terminal statuses (Closed, Canceled, Done).
   • IMPORTANT: Filter out blocked tickets (query tracker/.link-index.csv for entries where source_ticket matches your ticket ID and link_type=Blocks)
   • IMPORTANT: Filter out tickets where you are not responsible for currents status processing
   • Identify non-blocked tickets in priority order (Critical > High > Medium > Low)
   • Within same priority, process blocking tickets first starting with oldest (by created timestamp)
2. Proceed with ticket execution:
   • MANDATORY: Use tracker/.instructions/index.md to identify the specific instruction file for this ticket type (e.g., task.md, feature-request.md, developer-story.md, etc.)
   • MANDATORY: READ the complete content of the identified instruction file from tracker/.instructions/[ticket-type].md
   • MANDATORY: STRICTLY FOLLOW the algorithm, rules, and procedures defined in that instruction file
   • The instruction file is your PRIMARY guide - it defines the workflow, status transitions, responsibilities, and requirements for this ticket type
   • CONTINUE WORKING on the ticket status-by-status, advancing to next status WHILE ALL of these conditions are true:
     • You are responsible for the current status
     • DoD criteria for current status are met
     • Ticket is not blocked
     • Ticket has not reached a terminal status
   • STOP WORKING when ANY of these conditions occur:
     • Ticket reaches terminal status
     • You are not responsible for next status (hand off to appropriate role)
     • Ticket becomes blocked (document blocker in comments)
     • DoD criteria cannot be met (escalate or create Question ticket)
3. If initial request doesn't mention specific ticket(s) to process, continue to step 1. to retrieve next ticket.

Documentation handling

🛑🛑🛑 CRITICAL DISTINCTION - VIOLATE AT YOUR PERIL 🛑🛑🛑

• ✅ DELIVERABLES = Produced outputs for stakeholders → Goes in docs/deliverables/
• ❌ DOCUMENTATION = Your work notes, progress, decisions → Goes in ticket comments.md EXCLUSIVELY AND WITHOUT EXCEPTION

1. 🛑 TOTAL, COMPLETE, ABSOLUTE BAN ON DOCUMENTATION FILES 🛑: You are CATEGORICALLY, UNEQUIVOCALLY, AND PERMANENTLY FORBIDDEN from creating:

   • ❌❌❌ COMPLETION-REPORT.md, completion-report.md, completion_report.*
   • ❌❌❌ dor-completion.md, dor-completion-report.md, dor_report.*
   • ❌❌❌ EXECUTION-SUMMARY.md, execution-summary.md, execution_summary.*
   • ❌❌❌ PROGRESS-REPORT.md, progress-*.md, progress_*.md
   • ❌❌❌ DESIGN-NOTES.md, implementation-notes.md, *-notes.md
   • ❌❌❌ STATUS-UPDATE.md, work-log.md, *-log.md, work_log.*
   • ❌❌❌ planning-*.md, plan-*.md, summary-*.md, report-*.md
   • ❌❌❌ ANY FILE OF ANY NAME OR EXTENSION DOCUMENTING YOUR WORK PROCESS, PROGRESS, DECISIONS, OR ACTIVITIES
   • SOLE EXCEPTION: Files EXPLICITLY AND SPECIFICALLY defined in ticket's Acceptance Criteria as stakeholder deliverables (and even then, verify it's not internal documentation disguised as a deliverable)

2. 🛑 WHERE TO DOCUMENT YOUR WORK - THERE IS ONLY ONE ANSWER 🛑:

   • ✅ ALWAYS, EXCLUSIVELY, WITHOUT EXCEPTION: Add to ticket's comments.md file AND NOWHERE ELSE
   • ✅ Include: plans, decisions, progress updates, blockers, handoffs, summaries, completions, status - ALL OF IT GOES IN COMMENTS
   • ✅ Format: timestamped entries with clear context
   • 🛑 NEVER create a separate file - NO MATTER HOW TEMPTING OR "ORGANIZED" IT SEEMS

3. DELIVERABLES (Allowed in docs/deliverables/):

   • ✅ Architecture Decision Records (ADRs)
   • ✅ Technical Specifications
   • ✅ Requirements Documents
   • ✅ API Documentation
   • ✅ Design Documents
   • ✅ Implementation Plans for stakeholders
   • ✅ User Guides, Deployment Guides
   • RULE: Must be explicitly requested in ticket or part of deliverable templates

4. 🛑 MANDATORY VERIFICATION BEFORE CREATING ANY FILE - NO SHORTCUTS 🛑:

   • STOP AND ASK: "Will external stakeholders read this, or is it internal documentation of my work?"
   • If internal/work notes → STOP IMMEDIATELY → use comments.md ONLY
   • If stakeholder deliverable → TRIPLE-CHECK it's explicitly in ticket Acceptance Criteria → THEN AND ONLY THEN → use docs/deliverables/
   • WHEN IN DOUBT: Use comments.md. ALWAYS ERR ON THE SIDE OF COMMENTS.

5. IMPORTANT: Always consult relevant documentation listed the docs/document_index.md before making decisions. This includes customer input documents, requirements specifications, technical constraints, and current project documentation. Requirements may evolve following agile practices, so always consult the latest version.

6. IMPORTANT Keep up-to-date document list in docs/document_index.md to track all relevant documentation. Consult this list and explore relevant documents before making architectural decisions or providing guidance.

7. Special Handling for Constraint/Policy Change Tickets:

   • MANDATORY PROCESS: If ticket introduces/modifies constraints, policies, or architectural decisions:
     • ✅ Update all relevant documentation (requirements, architecture, plans)
     • ✅ Search tracker for affected tickets: grep "keyword" tracker/.index.csv
     • ✅ For completed tickets: Create remediation tickets + establish links
     • ✅ For in-progress tickets: Add comments and constraint references
     • ✅ For not-started tickets: Add constraint reference by appending link to tracker/.link-index.csv
     • ✅ Establish complete link chains (all links stored in centralized CSV)
     • ✅ Summarize total remediation effort and priority in comments
     • ✅ Update tracker index with all new remediation tickets

Environment Detection for Terminal Commands

CRITICAL: Before executing any terminal commands, ALWAYS detect the operating system environment and use appropriate syntax.

Detection Methods:

• Check for Windows-specific environment variables (e.g., USERPROFILE, WINDIR)
• Check for Unix-style paths (/home, /usr)
• Use platform detection tools available in your execution environment

Platform-Specific Syntax:

Windows (PowerShell/CMD):

• Test execution: python -m pytest or pytest.exe
• Coverage: python -m pytest --cov
• Path separator: \ (backslash)
• Command chaining: ; (PowerShell), && (CMD)
• Example PowerShell: cd C:\project; python -m pytest tests\
• Example CMD: cd C:\project && python -m pytest tests\
• PowerShell policy bypass: powershell -ExecutionPolicy Bypass -File "C:\path\to\script.ps1"

Linux/macOS (Bash/sh):

• Test execution: python3 -m pytest or pytest
• Coverage: python3 -m pytest --cov
• Path separator: / (forward slash)
• Example: cd /home/project && python3 -m pytest tests/

Best Practices:

• Always confirm environment before running test commands
• Use platform-agnostic test invocation: python -m pytest
• Be aware of path separators in test file paths
• Test commands for the detected environment
