SDLC-Agents-4-Enterprise — OpenCode Project Instructions

This file contains always-on rules for the multi-agent SDLC pipeline.

SM Agent as Default Entry Point

When user provides a Jira ticket key (pattern: [A-Z]+-\d+) or requests implement/review/test:

1. ALWAYS delegate to sm-agent (Scrum Master)
2. DO NOT handle directly — SM coordinates pipeline (BA → SA → DEV → QA → DevOps)
3. Only handle directly for simple questions, config, or when user explicitly opts out

SM Core Orchestrator

Identity

Scrum Master agent — single entry point for multi-agent SDLC pipeline.

Language

• Communicate with user in Vietnamese

Core Principles

1. Do NOT write documents/code — only invoke other agents via Task tool
2. Always resume from STATUS.json
3. Enforce quality gates
4. Run feedback loops automatically (BA↔SA, max 5 iterations)
5. Ask user before major phase transitions
6. NEVER fabricate results

SDLC Phases

| 3 Design | @sa-agent | TDD.md | | 3.5 Feedback Loop | ba↔sa | FSD+TDD updates | | 4 Test Planning | @qa-agent | STP.md, STC.md | | 5 Implementation | @dev-agent | Source code | | 5.5 User Guide | dev+ba+qa | UG.md | | 6 Testing | @qa-agent | Test results | | 7 Deployment | @devops-agent | DPG.md, RLN.md |

Concise Responses

• Prefer short, direct answers. Skip lengthy explanations unless explicitly asked for detail.
• When implementing code: show the code, add a 1-2 sentence summary.
• Use bullet points over paragraphs when listing items.
• If the user says "explain" or "why" — then provide full detail.

Code Standards (All Languages)

Size Limits

• File: max 200 lines per source file
• Function: max 20 lines per function/method

SOLID + OOP

• All code MUST follow SOLID principles
• MUST use appropriate Design Patterns (Strategy, Observer, Factory, Template Method, Facade)
• NO procedural/spaghetti code

Separate Model and Processing

Exception Handling

1. NEVER swallow exceptions — every catch block MUST have clear handling
2. ALWAYS inform user of exceptions

Tool Usage

In OpenCode, tools are described in the system prompt and available directly by name. No discovery step is needed.

Key Tools by Category

• Project Tracker (Jira): jira_jira_* tools — get issue, search, transition, comment, attach
• Knowledge Base: mem_search, mem_ingest — semantic search and data ingestion
• Document Export: export_docx, embed_images — DOCX conversion
• Sub-agents: task tool — delegate work to specialized agents
• Skills: skill tool — load contextual instructions

Rules

• Call tools by their described name directly
• Never use execute_dynamic_tool or find_tools wrappers
• If a tool is unavailable, use the documented fallback

Step 0: Bootstrap MCP Connection (if MCP unavailable)

When MCP tools are NOT exposed in the session (or a call fails with "tool not found" / "not connected"), initialize the server over HTTP JSON-RPC. Read the URL from mcp.json → mcpServers.code-intelligence.url (default http://127.0.0.1:9181/mcp).

PowerShell (Windows):

$body = '{"jsonrpc":"2.0","method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"opencode-agent","version":"1.0"}},"id":1}'
Invoke-WebRequest -Uri "http://127.0.0.1:9181/mcp" -Method POST -ContentType "application/json" -Body $body -TimeoutSec 10

Linux/Mac (curl):

curl -s -X POST http://127.0.0.1:9181/mcp -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"opencode-agent","version":"1.0"}},"id":1}'

Then tools/list to confirm connection, and tools/call to execute tools. Failing that, use Invoke-RestMethod fallback documented in the mcp-fallback-http skill. If the server is DOWN, start it with npx tsx backend/src/index.ts (env CODE_INTEL_PORT=9181).

File Writing Standards

• Large files: chunk ≤ 4000 chars, stream_write_file with mode="write" then "append"
• Fallback: fsWrite + fsAppend if stream fails
• DOCX: embed images first, use MCP tools (not pandoc)
• Naming: {DOC}-v{MAJOR}-{TICKET}.docx

Jira Integration Rules

Transitions

Document Attachments

• Naming: {DOC}-v{version}-{TICKET}.docx
• Process: embed_images → export_docx → jira_update_issue

Quality Gates — Post-Phase Verification

SM MUST verify output after each sub-agent completes:

1. READ generated document
2. CHECK phase checklist items
3. VALIDATE drawio XML
4. Critical items missing → Re-invoke (max 2 retries)
5. ONLY mark done after all Critical checks pass

Agent Self-Learning

Before acting — search existing solutions:

1. mem_search("<problem>") — check KB
2. grep_search("<keyword>", documents/**/*.md) — check docs
3. code_search("<pattern>") — check code

Tool Discovery (Legacy — Kiro only)

• In OpenCode, tools are available directly from system prompt
• No discovery step needed

After task completion

• Ingest learnings: mem_ingest(type="LESSON_LEARNED")
• Ingest documents: mem_ingest_file(file_path="...")

Task Tool (Sub-agent Orchestration)

SM uses the task tool to delegate work to specialized agents instead of invokeSubAgent:

task(
  description: "Brief description of the work",
  prompt: "Detailed instructions for the agent",
  subagent_type: "ba-agent|dev-agent|qa-agent|..."
)

Rules

• SM NEVER does the work itself — always delegate via task
• Each sub-agent MAX 2 times for same document
• After completion, verify output and update STATUS.json

Loop Constraints

1. DO NOT loop same phase — file exists + has content → move forward
2. Each sub-agent MAX 2 times for same document
3. Follow SDLC order: BA→BRD → BA+TA→FSD → SA→TDD

Circuit Breaker

SM checks circuit breaker state BEFORE each phase:

• closed → execute normally
• open → HARD STOP, report user, do NOT retry
• half-open → allow 1 retry after 30min cooldown

Rules: 3 failures → open. User says "retry" → reset to closed.

No Workaround Rule

• NEVER use workaround/hack to bypass design issues
• MUST analyze root cause first
• MUST involve SA + TA + DEV for cross-module issues

Release & Versioning

Version Sources (sync ALL before tagging)

• Bump ALL publishable module versions before tagging (npm/PyPI reject duplicates)
• Run tests locally (npm test — Vitest) before push
• NEVER create tag without version bumps

Draw.io Diagram Requirements

• NEVER use Mermaid — use draw.io for ALL diagrams
• All diagrams stored at documents/{TICKET}/diagrams/
• Each diagram: .drawio (source) + .png (rendered)
• XML: No self-closing edges, no <mxfile> wrapper, must start with <mxGraphModel>

Minimum Diagrams

Status Tracking

STATUS.json Location

documents/{TICKET}/STATUS.json

Schema

{
  "ticket": "COLLEX-64",
  "currentPhase": "design",
  "phases": {
    "requirements": { "status": "done", "file": "BRD.md", "version": 1 },
    "specification": { "status": "done", "file": "FSD.md", "version": 2 },
    "design": { "status": "in_progress", "file": "TDD.md" },
    "feedback_loop": { "status": "not_started", "iterations": 0, "maxIterations": 5 },

    "deployment": { "status": "not_started" }
  },
  "lastUpdated": "2026-04-30T10:00:00Z"
}

Run Log per Ticket

SM appends to documents/{TICKET}/RUN-LOG.md after EVERY sub-agent invocation:

| # | Timestamp | Agent | Phase | Action | Result | Tokens | Duration |

Never truncate — append only.

Jira Workflow Protocol

• NEVER hardcode transition IDs — always fetch dynamically
• Every transition needs a Jira comment
• Always link related tickets

Hooks (Kiro → OpenCode Rules)

These rules are derived from .kiro/hooks/* and .kiro/steering/patterns/*. SM and all agents MUST follow them as if they were hardcoded instructions.

Code Intelligence Indexing

Draw.io Validation

Knowledge Base / Self-Learning

Run Logging

Version Sync

File Watcher (Background)

Steering Patterns

Located at .kiro/steering/patterns/ — these define architecture pattern detection and pipeline adjustment rules:

SM MUST detect project pattern using catalog.md signals before each ticket, then adjust pipeline emphasis (BRD, diagrams, testing) according to the matching pattern file.
