Shared delegation contract for SGAI agents that invoke Task subagents. Use before delegating implementation, review, verification, deployment, writing, safety review, or project-critic work.
Skill Claude CodeCodex
Shared return contract for SGAI Task subagents. Use before any delegated implementation, deployment, writing, verification, review, or project-critic subagent reports back to its caller.

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions.
Skill Claude CodeCodex
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first.
Skill Claude CodeCodex
Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies.
Skill Claude CodeCodex
Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes.

YOU MUST USE THIS SKILL WHENEVER YOU NEED TO USE git OR jj. Use jj instead of git for version control operations. When you need to perform version control tasks like committing, branching, merging, etc. Traps git use cases to steer to jj.
Skill Claude CodeCodex
Use when starting any conversation - establishes mandatory workflows for finding and using skills, including using Skill tool before announcing usage, following brainstorming before coding, and creating TodoWrite todos for checklists.
Skill Claude CodeCodex
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always.

Run and manage ad-hoc AI prompts in sgai workspaces without starting a full agentic session. Use when you need to run a one-off AI prompt against a workspace, check the status of a running ad-hoc prompt, or stop a running ad-hoc prompt.
Skill Claude CodeCodex
Use the sgai compose wizard to create and manage GOAL.md files for workspaces. Supports reading compose state, updating wizard fields, saving drafts, previewing generated GOAL.md content, browsing workflow templates, and writing the final GOAL.md to the workspace.
