If the user reports the result is wrong (e.g. aggregation values don't match), retry with `analyst`. Only use `builder` when the task genuinely needs the warehouse-investigation tools (it's 10–20× more expensive than fast-edit and rarely required). -**Recommended invocation** — captures the final response to a file and runs in the right directory: +### Step 2 — invoke with the chosen agent ```bash -altimate-code run "" \ +altimate-code run "" \ + --agent \ --yolo \ --output /tmp/altimate-result.md \ --dir "$(pwd)" ``` -Then read `/tmp/altimate-result.md` and pass it straight back to the user. +Then `Read /tmp/altimate-result.md` and emit its contents to the user without re-summarising, re-formatting, or commenting on the result. altimate-code has already produced the answer. -### Key flags +### Required flags -| Flag | When to use | +| Flag | Why it is required | |---|---| -| `--yolo` | Required for non-interactive — auto-approves tool calls. Without this it hangs on the first permission prompt. | -| `--output ` | Write the final assistant response to a file. Use `.md` or `.txt`. | -| `--dir ` | Run the agent in a specific directory (e.g. a dbt project root). Defaults to cwd. | -| `--model provider/model` | Override the model. Useful for fast/cheap exploration. | -| `--format json` | Emit raw JSON events instead of formatted output. Use only when post-processing programmatically. | -| `--continue` / `--session ` | Continue a previous altimate-code session. | - -### Example invocations +| `--agent ` | Picks the agent persona. Default `builder` is overkill for simple edits — see the classification table above. Wrong agent = either 10× too expensive (using `builder` on a rename) or wrong-answer (using `fast-edit` on a multi-table join). | +| `--yolo` | Non-interactive mode. Without this the subprocess hangs on the first permission prompt and you will time out. | +| `--output /tmp/altimate-result.md` | Captures the final response. Without this you lose the answer to stdout-buffering and can't reliably read it back. | +| `--dir "$(pwd)"` | Runs altimate-code in the current project so it picks up dbt project config, profiles.yml, etc. | -**Find expensive queries in Snowflake:** +### Follow-up tasks in the same project -```bash -altimate-code run "Find the top 10 most expensive queries from the last 7 days in Snowflake and explain why each is slow." \ - --yolo --output /tmp/expensive.md -``` - -**Generate column-level lineage for a dbt model:** +When the user makes a follow-up data task in the same project after a successful altimate-code delegation, prefer `--continue` to resume the warm session instead of starting a fresh one: ```bash -altimate-code run "Show column-level lineage for the dim_customers model, including upstream sources and downstream consumers." \ - --yolo --dir "$(pwd)" --output /tmp/lineage.md +altimate-code run "" \ + --agent \ + --yolo \ + --output /tmp/altimate-result.md \ + --dir "$(pwd)" \ + --continue # resumes the most recent session in this dir ``` -**Profile a table:** +altimate-code's prompt cache is warm in a continued session — project structure, profiles.yml, schema index, source definitions don't need to be re-investigated. Cache reads are billed at a fraction of fresh input on altimate-gateway. The downside is zero: if there's no useful cached context for the new task, you pay normal cold cost. -```bash -altimate-code run "Profile the events table — row count, null distribution per column, cardinality, and top 5 values for low-cardinality columns." \ - --yolo --output /tmp/profile.md -``` +If the user starts a clearly unrelated workflow (different project, different schema, different debugging thread), drop `--continue` and start fresh — the warm cache is irrelevant and you'd carry unrelated history into the prompt. -## Presenting the Result +## Failure modes — route every one to the user -Read the output file with the Read tool and pass the content through to the user as-is.
