🤖 Agents

Dataviewer Developer

Interactive agent for launching, browsing, annotating, and improving the Dataset Analysis Tool.

Property	Value
Handoffs	Start Dataviewer, Browse Dataset, Annotate Episodes
Tools	All (no restrictions)
Skill	dataviewer
Prompts	/start-dataviewer

Four-phase workflow: Launch/Configure → Interactive Browsing (Playwright) → Episode Annotation (API+UI) → Feature Development (React+FastAPI).

OSMO Training Manager

Multi-turn agent for managing LeRobot imitation learning training lifecycle on OSMO with Azure ML integration.

Property	Value
Handoffs	Submit Training Job, Check Training Status, Run Inference Evaluation
Tools	11 explicit (run_in_terminal, memory, runSubagent, ...)
Skill	osmo-lerobot-training
Prompts	/submit-lerobot-training, /check-training-status

Five-phase workflow: Submit → Monitor → Analyze → Summarize → Inference Evaluation. Handles VM eviction recovery, CUDA errors, and KeyError failures.

📝 Instructions

Instructions activate automatically when files matching their applyTo pattern appear in the chat context.

Name	Applies To	Purpose
Commit Messages	**	Conventional Commits format, scopes, line-length limits
Dataviewer	data-management/viewer/**	SOLID principles, test-first, validation commands
Docs Style and Conventions	**/*.md	Document hierarchy, tables, voice/tone, frontmatter
Shell Scripts	**/*.sh	Script template, library functions, deployment patterns

⚡ Prompts

Prompts are slash commands invoked via / in the chat input. Each prompt targets a specific agent.

Command	Agent Target	Required Inputs
/chatlog	Generic	None
/check-training-status	OSMO Training Manager	workflowId (optional)
/start-dataviewer	Dataviewer Developer	datasetPath
/submit-lerobot-training	OSMO Training Manager	dataset (required)

🛠️ Skills

Skills provide multi-file capabilities with progressive 3-level loading: discovery (frontmatter only) → instructions (SKILL.md body) → resources (bundled reference files).

dataviewer

Property	Value
Directory	.github/skills/dataviewer/
Resources	references/PLAYWRIGHT.md (selectors, interaction recipes, API endpoints)
Used by	Dataviewer Developer agent

osmo-lerobot-training

Property	Value
Directory	.github/skills/osmo-lerobot-training/
Resources	references/DEFAULTS.md (env, datasets, GPU profiles), references/REFERENCE.md (CLI, inference, AzureML navigation)
Used by	OSMO Training Manager agent

🔄 Workflow Chains

Agents compose prompts and skills into end-to-end workflows:

OSMO Training Manager (agent)
  ├── /submit-lerobot-training (prompt)
  ├── /check-training-status   (prompt)
  └── osmo-lerobot-training    (skill)
       ├── references/DEFAULTS.md
       └── references/REFERENCE.md

Dataviewer Developer (agent)
  ├── /start-dataviewer        (prompt)
  └── dataviewer               (skill)
       └── references/PLAYWRIGHT.md

Standalone:
  └── /chatlog                 (prompt, generic)

➕ Adding New Artifacts

VS Code provides generator commands for scaffolding new artifacts:

• /create-agent — Create a new custom agent
• /create-instruction — Create a new instruction file
• /create-prompt — Create a new prompt file
• /create-skill — Create a new agent skill

Place new artifacts in the corresponding .github/ subdirectory and update this inventory page.
