OST

Run a full Opportunity Solution Tree workflow from a single skill, backed by a lightweight graph database and CLI.

Entry Flow (Minimize File Loading)

Goal: Start a session, pick a workspace, and select or create an outcome.

1. Ensure DB exists

• If .agr/ost.db is missing, initialize it:

- uv run python scripts/ost.py init --path.agr/ost.db

1. Select workspace

• List workspaces:

- uv run python scripts/ost.py workspace list

• If needed, create one:

- uv run python scripts/ost.py workspace create \"<name>\"

1. Select outcome

• List outcomes:

- uv run python scripts/ost.py outcome list --workspace <name>

• If needed, create one:

- uv run python scripts/ost.py outcome add --workspace <name> \"<title>\"

1. Route to phase (load only the relevant file)

• Outcomes: references/outcomes.md
• Opportunities: references/opportunities.md
• Solutions: references/solutions.md
• Assumptions/Experiments: references/assumptions.md

Data Model + Storage

Use a lightweight graph DB at .agr/ost.db with multi-workspace support. The CLI manages nodes and edges; do not edit DB files manually.

CLI

Use the CLI to read/write the OST graph. The CLI is expected to live in this skill’s scripts/ directory and be run via uv run.

Commands (intended):

• uv run python scripts/ost.py init --path.agr/ost.db
• uv run python scripts/ost.py workspace list
• uv run python scripts/ost.py workspace create "<name>"
• uv run python scripts/ost.py outcome list --workspace <name>
• uv run python scripts/ost.py outcome add --workspace <name> "<title>"
• uv run python scripts/ost.py opportunity add --outcome <id> "<title>"
• uv run python scripts/ost.py solution add --opportunity <id> "<title>"
• uv run python scripts/ost.py assumption add --solution <id> "<title>"
• uv run python scripts/ost.py show --outcome <id>

If the CLI is not yet implemented, document the intended command and proceed with non-destructive guidance only.

Output Format

## OST Session

### Selected Workspace
- Name: ...

### Selected Outcome
- ID: ...
- Title: ...

### Next Action
- [What the user wants to do next]

### Next Step
- Load the relevant phase reference file

What NOT to Do

• Do NOT edit .agr/ost.db directly.
• Do NOT invent node IDs.
• Do NOT run destructive commands without explicit user intent.
