# Toxicity Structure Alert (Skill ID: 141) Identify potential toxic structural alerts in drug molecules. ## When to Use - Use this skill when the task is to Identify potential toxic structural alerts in drug molecules by scanning. - Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format. - Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence. ## Key Features See `## Features` above for related details. - Scope-focused workflow aligned to: Analyze data with `toxicity-structure-alert` using a reproducible workflow, explicit validation, and structured outputs for review-ready interpretation. - Packaged executable path(s): `scripts/main.py`. - Reference material available in `references/` for task-specific guidance. - Structured execution path designed to keep outputs consistent and reviewable. ## Dependencies - Python 3.8+ - RDKit ## Example Usage See `## Usage` above for related details. ```bash cd "20260318/scientific-skills/Data Analytics/toxicity-structure-alert" python -m py_compile scripts/main.py python scripts/main.py --help ``` Example run plan: 1. Confirm the user input, output path, and any required config values. 2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings. 3. Run `python scripts/main.py` with the validated inputs. 4. Review the generated output and return the final artifact with any assumptions called out. ## Implementation Details See `## Workflow` above for related details. - Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable. - Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script. - Primary implementation surface: `scripts/main.py`. - Reference guidance: `references/` contains supporting rules, prompts, or checklists. - Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints. - Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects. ## Quick Check Use this command to verify that the packaged script entry point can be parsed before deeper execution. ```bash python -m py_compile scripts/main.py ``` ## Audit-Ready Commands Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths. ```bash python -m py_compile scripts/main.py python scripts/main.py --help python scripts/main.py --input "Audit validation sample with explicit symptoms, history, assessment, and next-step plan." --format json ``` ## Workflow 1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work. 2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions. 3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available. 4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items. 5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion. ## Features - Scan molecular structures (SMILES/SMARTS) - Identify known toxic structural alerts - Assess potential toxicity risk levels - Generate detailed reports ## Supported Alert Structures | Alert Structure | Toxicity Type | Risk Level | |---------|---------|---------| | Aromatic Nitro | Mutagenicity | High | | Aromatic Amine | Carcinogenicity | High | | Epoxide | Alkylating Agent | High | | Aldehyde | Reactive Toxicity | Medium | | Acyl Chloride | Reactive Toxicity | Medium | | Michael Acceptor | Electrophilic Toxicity | Medium | | Hydrazine | Hepatotoxicity | High | | Haloalkyl | Alkylating Agent | High | | Quinone | Oxidative Stress | Medium | | Thiol-Reactive Groups | Protein Binding | Low-Medium | ## Usage ```text python -m py_compile scripts/main.py # Example invocation: python scripts/main.py --input <smiles_string> [--format json|text] ``` ### Parameters - `--input, -i`: Input SMILES string (required) - `--format, -f`: Output format, optional `json` or `text` (default: text) - `--detail, -d`: Detail level, optional `basic`, `standard`, `full` (default: standard) ### Examples ```text # Basic text output python scripts/main.py -i "O=[N+]([O-])c1ccccc1" # JSON format output python scripts/main.py -i "O=C1OC1c1ccccc1" -f json # Detailed report python scripts/main.py -i "c1ccc2c(c1)ccc1c3ccccc3ccc21" -d full ``` ### Python API ```python from scripts.main import ToxicityAlertScanner scanner = ToxicityAlertScanner() result = scanner.scan("O=[N+]([O-])c1ccccc1") print(result.alerts) ``` ## Output Format ### JSON Output ```json { "input": "O=[N+]([O-])c1ccccc1", "mol_weight": 123.11, "alert_count": 1, "risk_score": 0.85, "risk_level": "HIGH", "alerts": [ { "name": "Aromatic Nitro", "type": "mutagenic", "smarts": "[N+](=O)[O-]", "risk_level": "HIGH", "description": "May cause DNA damage and mutagenicity" } ], "recommendations": [ "Recommend Ames test validation", "Consider structural optimization to reduce toxicity" ] } ``` ## Risk Levels - **HIGH**: Known significant toxicity, strongly recommended to avoid - **MEDIUM**: Potential toxicity, further evaluation recommended - **LOW**: Minor concern, can be considered based on specific circumstances ## Notes 1. This tool is based on known alert structures and cannot replace comprehensive toxicological assessment 2. False positives and false negatives may both exist 3.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond: > `toxicity-structure-alert` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill. ## Response Template Use the following fixed structure for non-trivial requests: 1. Objective 2. Inputs Received 3. Assumptions 4. Workflow 5. Deliverable 6. Risks and Limits 7. Next Checks If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness. ## Inputs to Collect - Required inputs: the user goal, the primary data or source file, and the requested output format. - Optional inputs: output directory, formatting preferences, and validation constraints. - If a required input is unavailable, return a short clarification request before continuing. ## Output Contract - Return a short summary, the main deliverables, and any assumptions that materially affect interpretation. - If execution is partial, label what succeeded, what failed, and the next safe recovery step. - Keep the final answer within the documented scope of the skill. ## Validation and Safety Rules - Validate identifiers, file paths, and user-provided parameters before execution. - Do not fabricate results, metrics, citations, or downstream conclusions. - Use safe fallback behavior when dependencies, credentials, or required inputs are missing. - Surface any execution failure with a concise diagnosis and recovery path.
