## What it does

The skill accepts raw SMILES, CSV files with automatic SMILES-column detection, and `.smi` or `.txt` files. Each molecule gets solubility, permeability, and lipophilicity under `adme`. An optional `id` is returned as `external_id`, which keeps results linked to the original list.

The workflow builds a YAML or JSON payload, runs `estimate-cost`, and shows the price before submission. ADME costs $0.01 per molecule, with a hard limit of 128 molecules per request. Larger libraries must be split into batches and merged from their `run.json` files; an invalid SMILES only fails its own molecule.

\`run` submits and waits synchronously, then stores the result at `<root-dir>/<run-name>/run.json`. `boltz-api` must be available in `PATH`, and authentication must be valid. If the CLI is missing from `PATH`, setup through `boltz-cli-setup` is required before retrying. The returned values are approximate estimates for triage and ranking, not lab measurements.

## When to use it
- estimate solubility from SMILES
- check permeability without a protein target
- compare lipophilicity across a molecule list
- load compounds from CSV, `.smi`, or `.txt`
- split a library above 128 molecules into batches

## Example prompts
- Estimate solubility, permeability, and lipophilicity for this SMILES: `CCO`.
- Read `molecules.csv`, detect its SMILES column, and prepare an ADME run after showing the estimated cost.
- Process `library.smi`, split it into valid request batches, and combine the results from `run.json`.

description: Predict Tier-1 ADME/ADMET for small molecules with Boltz from bare SMILES — no target, no docking. Use when the user wants solubility, permeability, or lipophilicity/logD for a molecule or list of molecules. Not for ranking molecules against a protein target (use boltz-small-molecule-screen, which already returns ADME free).

## Workflow

If `boltz-api` is missing from `PATH`, use `boltz-cli-setup` for install/update guidance before retrying.
If a command reports missing or expired authentication, use `boltz-cli-setup` to start `boltz-api auth login --device-code` before retrying; do not ask permission first.
If the agent host sandbox blocks `boltz-api` install/auth/API calls, use `boltz-cli-setup` to request the host sandbox bypass/escalation needed for user-wide CLI install, browser login, credential storage, temp files, or API access before retrying.

Use this skill for standalone ADME triage on SMILES the user already has. No protein target is involved. If the user is also screening or docking those molecules against a target, prefer `boltz-small-molecule-screen` — it returns the same ADME block free as part of the screen.

1. Normalize the molecules from raw SMILES, a CSV (auto-detect the SMILES column), `.smi`, or `.txt` into the `molecules` list. Each entry is `{smiles, id?}`; the optional `id` is echoed back as `external_id` on each result so you can map results to inputs.
2. **Hard cap: 128 molecules per request.** If the list exceeds 128, split into batches of ≤128 and submit one request per batch (suffix the run name, for example `-b1`, `-b2`), then merge results. Never send more than 128 in one call — the API rejects it with `VALIDATION_ERROR: input.molecules must contain at most 128 items`.
3. Author the payload YAML or JSON, run `estimate-cost`, show the USD cost, wait for explicit confirmation. ADME is priced at **$0.01 per molecule** (size-independent); `estimate-cost` returns the authoritative total — always quote it.
4. `run` to submit and wait — ADME finishes in seconds, so it is synchronous and needs no background polling. `run` persists results locally under `--root-dir/<run-name>/`.
5. Report from `<output-root>/<run-name>/run.json` → `output.molecules[]`. For each molecule show `external_id` (or `smiles`), `solubility`, `permeability`, and `lipophilicity`. The three values live under each molecule's `adme` object. Call out any molecule with `status: failed` and its `error` (an object `{code, message}`, e.g. code `adme_enumeration_failed`, message `Invalid SMILES`) — `adme` is `null` there; one bad SMILES fails only that molecule, not the batch. Read [references/results.md](references/results.md) for the output layout and [references/api.md](references/api.md) for the payload and batching details.

ADME values are approximate estimates for triage and ranking, not absolute measurements.
