Lobster AI Usage Guide — 1.2

Describe the biological task in natural language. Lobster routes it to installed specialist agents; do not assume every domain package is installed.

Choose the Correct Client

The npm client owns Cloud authentication and Cloud commands. Python/Go Cloud compatibility is not a supported client contract. Local chat uses Go TUI with a classic terminal fallback; Cloud chat uses the npm Ink TUI.

When both clients are installed, check which lobster. npm lobster init is a Cloud onboarding wizard, not local provider setup. In a Python development environment, use uv run python -m lobster init to target local setup explicitly.

Requirements and Permission Boundaries

• Local engine: Python 3.12+, an installed lobster-ai and relevant domain packages.
• Local inference: choose a configured provider. Examples: ANTHROPIC_API_KEY,

GOOGLE_API_KEY, OPENAI_API_KEY, OPENROUTER_API_KEY, NEBIUS_API_KEY; Bedrock uses AWS_BEDROCK_ACCESS_KEY + AWS_BEDROCK_SECRET_ACCESS_KEY; Azure uses AZURE_AI_ENDPOINT + AZURE_AI_CREDENTIAL. Ollama requires a running local model rather than an API key.

• Cloud: install npm @omicsos/lobster and authenticate with its login flow.

Canonical headless API-key environment variable: OMICSOS_API_KEY.

• Optional: NCBI_API_KEY for NCBI access.
• Obtain permission before installation, credential writes, downloads, paid

inference, or operations outside the user's chosen workspace. Never print keys.

Local data is stored in the chosen workspace, but local mode is not an offline or no-network promise: remote inference can send prompts and data context to the selected provider, and searches/downloads use external services. Review the data and provider policy before analyzing sensitive material.

Local Quick Start

The following examples assume lobster resolves to the Python engine. A virtual environment can instead use uv run python -m lobster in place of lobster.

# Install only with user permission
uv tool install 'lobster-ai[full]~=1.2'
 
# Configure the local engine (provider key supplied from the environment)
lobster init --non-interactive --anthropic-key "$ANTHROPIC_API_KEY" --profile production
lobster config-test --json
 
# Use the SAME workspace and session on every step
lobster query -w ./analysis --session-id study --json \
  "Find a suitable public RNA-seq dataset and explain its available data representations"
lobster command "workspace list" -w ./analysis --session-id study --json
lobster chat -w ./analysis --session-id study

-w ./analysis is the workspace root itself: do not append another .lobster_workspace when inspecting outputs. Without an override, the local workspace defaults to ./.lobster_workspace (or LOBSTER_WORKSPACE).

Cloud Quick Start — npm Client Only

npm install -g @omicsos/lobster  # only with permission
lobster cloud login            # user completes browser authentication
lobster cloud status
lobster cloud chat
lobster cloud query --json "Describe the data available in this session"

For headless use, provide OMICSOS_API_KEY through the environment. A stored credential file is not proof that authentication still works; check the supported client's result. Never copy credentials into a prompt or a report.

Scientific Workflow Rules

1. Check loaded modalities and sample metadata before analysis. Use

lobster command for supported local inspection commands without an LLM call.

1. Assess quality before selecting filters or an analysis model. Ask about

biological replicates, conditions and confounders; do not invent a design.

1. Keep raw counts separate from normalized representations. DESeq2 is not a

method for TPM, CPM, log-transformed or scaled expression.

1. For a bulk GEO count workflow, request

execute_download_from_queue(..., data_requirement="gene_counts") through the Data Expert. This is a tool argument, not a CLI flag. Empty requirement retains ordinary imports; gene_counts is GEO-only and conservative.

1. A count import refusal reports Requirement not met, its problem and candidate

reasons. It may mean no suitable file, ambiguity, sample identity mismatch or value-fidelity failure. Select another dataset or report the limitation; do not repeatedly retry unchanged or silently substitute normalized data.

1. DESeq2 prefers a valid layers['counts']; if absent, it checks X. An invalid

counts layer is refused, not bypassed using X. The matrix must be finite, nonnegative and whole-number. Passing that numeric check does not establish the biological origin of the counts: inspect the source and aggregation method.

Figures: Save, Then Edit the Saved Revision

These figure rules describe the local 1.2 engine, not Cloud feature availability.

• Run assess_data_quality before create_qc_plots, then draw the full QC-assessed

modality, not a DE/small-gene subset. Drawing does not compute or repair QC metrics.

• Templates draw from retained results; they do not rerun scientific analyses or

save a figure. Discover with list_templates(), get_template(name) and show_template_source(name) inside execute_custom_code.

• A Python fig variable is not saved automatically. Call

submit_figure(fig, source=rows, intent="what it shows", label="...") for each figure to retain. publish_plot(fig, title) is a compatibility alias without an explicit regeneration source.

• Figures are submitted only for saving after successful code execution. Check

the tool's save outcome: code success alone is not proof that a figure saved. Save confirmation pending. means confirmation is uncertain, not a definite absence; do not report it as a completed save.

• save_plot=False on plotting tools is preview-only, not a saved revision.
• For an edit request, load the literal saved ref with

load_figure("<figure_id>@<revision_id>"), change it, then submit with that same ref as parent. This retains the original and creates a new revision. Restyling or filtering an existing figure is an edit, not a new figure.

• An edit inherits the parent's saved Plotly config unless config is supplied;

config={} explicitly clears it. To retain regeneration data, supply source explicitly; neither a filename nor a variable name establishes source identity.

• Interactive /plots lists saved figures; /plot <identifier> opens one.

Programmatic listing is lobster command plots --json with workspace/session.

See CLI reference and orchestration patterns for examples.

Code Access, Cost and Failure Handling

The supervisor, data_expert_agent, metadata_assistant, and visualization_expert_agent have custom code enabled by default. Other participating built-in experts default to disabled; research_agent does not offer the tool. Override with LOBSTER_CODE_TOOL_<AGENT_NAME_UPPER>=1|0 or global LOBSTER_CODE_TOOL=all|none|default; workspace config.toml can also set [agent_settings.<agent_name>] code_tool = false. Per-agent environment beats global environment, then workspace settings, then the declared default; default defers. Per-agent 1 overrides global none.

The switch controls only the execute_custom_code tool; it does not disable other tools, including tools that run shell commands or write files.

Custom code runs as your own OS user, not within a confinement boundary. Run only code you trust. Its serialized result envelope is limited to 16 MiB; larger envelopes are unreadable and submitted figures are not saved. Write large outputs to workspace files and return compact summaries/paths. See CLI reference for exact value handling and configuration scope.

Bedrock prompt caching is OFF by default. For direct own-AWS Bedrock use with Anthropic models, LOBSTER_BEDROCK_PROMPT_CACHE=1 opts in to cache-point requests. This does not promise a cache hit or a saving; do not extend it to a Cloud activation claim.

Prices come from a packaged offline snapshot with manual overrides, not a live price fetch. Exact provider/model identity matters; missing rates are unknown, not zero. Local estimates are not provider invoices or Omics-OS Cloud tariffs.

/tokens displays totals and per-agent tokens/costs/calls, not completeness or pricing snapshots. Detailed callback usage summaries expose cost_complete, usage_complete, unpriced_invocations, unpriced_models, and attempt_coverage="callback_only". If pricing is incomplete, the priced sum is a lower bound; withhold derived cost metrics. Usage completeness is separate from pricing completeness, and callback-only coverage is not a complete provider bill.

Check both process status and JSON success. Local query --json failures return an error and exit nonzero. Preserve stderr privately; do not paste raw logs, credentials, patient data or provider request payloads into external reports. Typed inference refusals must not be worked around by switching credentials, authority or an unrelated scientific fallback. Report the limitation and ask for an authorized next step.

Default/relative analysis exports use the workspace's exports/ directory; inspect returned paths rather than assuming files were written to the shell's current directory. Notebook export is a selected subset of recorded steps, not evidence of execution. Custom code using attempt-only figure helpers is excluded from executable export; inspect the omission summary. Replay mode selects steps marked replayable and can refuse failed or unreplayable data-changing steps. Inspect and run the notebook separately before making any statement about its results.
