Dev Fix Agent Skill

Dev Fix Skill

> [!IMPORTANT]

> Unified developer workflow for fixing bugs. Analyzes issue-tracker context, cross-checks docs/code, proposes a solution, implements the fix, verifies locally, and delivers a PR/MR.

Optional args: slug=<feature>, ticket=<id/url>, mode=interactive|autonomous|channel, channel=<id>, auto_continue=true|false, profile=business|hybrid|technical.

Instructions

When the user asks to perform this workflow, execute the following steps:

Dev-Fix — Bug Remediation

Goal: Take a bug ticket from root-cause analysis through a locally-verified PR/MR, enforcing a strict Propose -> Approve -> Verify cycle.

Input

/dev-fix <issue-url-or-key>

Workflow

Step 0: Environment Prep (Turbo)

// turbo

• Sync Registry: git pull origin main in the standard repo.

Step 1: Research & Discovery (Implementation Plan Phase)

> [!TIP]

> Sub-Agent Delegation: If your platform supports sub-agents, delegate ticket extraction to specialist-jira-analyst and context lookup to specialist-codebase-scout. If sub-agents are NOT supported, execute these steps yourself.

• Analyze Ticket: Use installed Jira/GitHub/GitLab/ADO MCP first; otherwise use exported ticket text. Extract Reproduce steps, Expected Result, and Actual Result.
• Cross-Check Context: Use knowledge-base MCP when configured; otherwise use local code search. Locate relevant code.
• Create Implementation Plan:
• Use the Implementation Plan Template below.
• Initialize project-local docs/prd/prd-plan-[slug].md.
• Goal: Clear description of the root cause.
• Proposed Changes: Exact files and logic to be modified.
• Verification Plan: Detail which QE skill will be used to verify the fix _locally_ before PR.
• Do not propose code changes until repro steps, expected result, and root cause hypothesis are explicit.
• HARD STOP: Request user approval for the implementation plan.
• Readiness Gate: Run implementation-readiness; code only after READY or approved PARTIAL.

Step 2: Implementation (TDD Phase)

> [!TIP]

> Sub-Agent Delegation: For the actual fix, delegate the TDD loop to specialist-tdd-implementer. If sub-agents are NOT supported, execute the TDD loop yourself using the TDD skill matched in AGENTS.md.

• Worktree Branching: Create a new worktree for the fix using git worktree add ../<ticket-key> -b fix/<ticket-key> and cd into it.
• Task Tracking:
• Use the Task Template below.
• Initialize project-local docs/srs/srs-task-list.md.
• Code: Implement the fix using common-tdd or the @specialist-tdd-implementer sub-agent. Follow common-best-practices and service-specific AGENTS.md rules.
• Delete any pre-test implementation spike before starting the TDD loop.

Step 3: Local Verification (Enterprise Standard)

Do NOT rely on "it builds" — verify the fix against the issue reproduction steps.

• Launch Dev Server: Run the local dev environment for the service.
• Execute QE Audit:
• Web: Load quality-engineering-playwright-cli. Run the reproduction steps. Capture "After" snapshots.
• Mobile: Load quality-engineering-appium-mcp. Run the reproduction steps on an emulator.
• Final Verdict: Compare results against the issue Expected Result. If any sub-3px regressions exist, fix them now.
• No success claim without fresh local evidence in docs/srs/srs-walkthrough.md.

Step 4: Deliver PR

• Commit: Generate a commit message using caveman-commit.
• PR/MR Details: Draft provider-appropriate PR/MR notes and link the source issue.
• Walkthrough:
• Use the Walkthrough Template below.
• Create project-local docs/srs/srs-walkthrough.md with evidence of the local verification.

Runtime Contract

• Use for bug tickets that need root-cause remediation and a PR/MR.
• Required inputs: issue URL/key or exported ticket text with reproduce steps.
• Return BLOCKED only when repro steps, expected result, or root-cause hypothesis cannot be established.

Handoff Payload

• slug, operator_profile (carried, not re-inferred), implementation plan path, task list path, walkthrough path, PR/MR link, outcome report, next workflow.

Blocking Questions

• Ask max 3 at a time with a recommended default and 2-3 options.

Cost Report

Call get_session_cost(workflow="dev-fix") before final handoff.

Anti-Patterns

• No Blind Implementation: Never write code before the implementation plan is approved.
• No Orphan Sessions: Always close browser/appium sessions used during verification.
• No skipping local verify: "I checked it manually" is not enough. Provide snapshots/logs in the project-local docs/srs/srs-walkthrough.md.
