When to Use

• Use this skill when the request matches its documented task boundary.
• Use it when the user can provide the required inputs and expects a structured deliverable.
• Prefer this skill for repeatable, checklist-driven execution rather than open-ended brainstorming.

Key Features

• Scope-focused workflow aligned to: "Generate forest plots for meta-analysis of survival data. Input is a CSV file containing study names, HR and 95% confidence intervals, output forest plot PNG and data table CSV. Supports both R and Python scripts.".
• Packaged executable path(s): scripts/forest_survival.py plus 1 additional script(s).
• Structured execution path designed to keep outputs consistent and reviewable.

Dependencies

• Python: 3.10+. Repository baseline for current packaged skills.
• Third-party packages: not explicitly version-pinned in this skill package. Add pinned versions if this skill needs stricter environment control.

Example Usage

cd "20260316/scientific-skills/Data Analytics/meta-forest-model-plot"
python -m py_compile scripts/forest_survival.py
python scripts/forest_survival.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/forest_survival.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/forest_survival.py with additional helper scripts under scripts/.
• 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.

Validation Shortcut

Run this minimal command first to verify the supported execution path:

python scripts/validate_skill.py --help

Data Format Requirements

Users need to provide a CSV file with the following columns:

Column Name	Description	Example
study	Study name (author + year)	Smith 2020
outcome_new	Outcome indicator name	Overall Survival
group1_HR	Hazard Ratio	0.85
group1_95%Lower CI or group1_95.Lower.CI	95% Confidence Interval Lower Bound	0.72
group1_95%Upper CI or group1_95.Upper.CI	95% Confidence Interval Upper Bound	1.01

Note: HR, Lower CI, and Upper CI must all be positive numbers.

---

Workflow

Step 1: Validate Input Data

1. Read the CSV file provided by the user
2. Check if necessary columns exist (supports two column name formats)
3. Validate data integrity (at least 2 studies, HR and CI are positive numbers)

If there are data issues, prompt the user to correct and resubmit.

Step 2: Execute Script (R or Python)

Option A: Using R Script (Recommended)

Command:

Rscript scripts/forest_survival.R "<csv_path>" "<outcome_name>" "<output_dir>"

Option B: Using Python Script (Backup)

Command:

python scripts/forest_survival.py "<csv_path>" "<outcome_name>" "<output_dir>"

Parameter Description (same for both scripts):

• csv_path: Absolute path to the input CSV file
• outcome_name: Outcome indicator name (optional, default extracted from data)
• output_dir: Output directory (optional, default is current directory)

Step 3: Output Results

Upon successful execution:

═══════════════════════════════════════════
Forest Plot Generation Complete
═══════════════════════════════════════════

【Outcome Indicator】{outcome_name}
【Included Studies】{n} studies

【Output Files】
• Forest Plot: {output_dir}/Survival_forest_{outcome}.png
• Data Table: {output_dir}/Survival_forest_{outcome}.csv

【Pooled Effect Size】
• HR = {value} [{lower}; {upper}]
• P value = {p_value}

【Heterogeneity】
• I² = {I2}%
• Tau² = {tau2}
• Q test P value = {pval_Q}

Script Dependencies

R Script Dependencies

Install the following R packages:

• meta
• metafor
• grid
• stringr

If the user's environment is missing these packages, prompt them to run:

install.packages(c("meta", "metafor", "grid", "stringr"))

Python Script Dependencies

Install the following Python packages (Python 3.7+ recommended):

• pandas
• numpy
• matplotlib
• scipy

If the user's environment is missing these packages, prompt them to run:

pip install pandas numpy matplotlib scipy

Or in a virtual environment:

python -m pip install pandas numpy matplotlib scipy

When Not to Use

• Do not use this skill when the required source data, identifiers, files, or credentials are missing.
• Do not use this skill when the user asks for fabricated results, unsupported claims, or out-of-scope conclusions.
• Do not use this skill when a simpler direct answer is more appropriate than the documented workflow.

Required Inputs

• A clearly specified task goal aligned with the documented scope.
• All required files, identifiers, parameters, or environment variables before execution.
• Any domain constraints, formatting requirements, and expected output destination if applicable.

Output Contract

• Return a structured deliverable that is directly usable without reformatting.
• If a file is produced, prefer a deterministic output name such as meta_forest_model_plot_result.md unless the skill documentation defines a better convention.
• Include a short validation summary describing what was checked, what assumptions were made, and any remaining limitations.

Validation and Safety Rules

• Validate required inputs before execution and stop early when mandatory fields or files are missing.
• Do not fabricate measurements, references, findings, or conclusions that are not supported by the provided source material.
• Emit a clear warning when credentials, privacy constraints, safety boundaries, or unsupported requests affect the result.
• Keep the output safe, reproducible, and within the documented scope at all times.

Failure Handling

• If validation fails, explain the exact missing field, file, or parameter and show the minimum fix required.
• If an external dependency or script fails, surface the command path, likely cause, and the next recovery step.
• If partial output is returned, label it clearly and identify which checks could not be completed.

Quick Validation

Run this minimal verification path before full execution when possible:

python scripts/forest_survival.py --help

Expected output format:

Result file: meta_forest_model_plot_result.md
Validation summary: PASS/FAIL with brief notes
Assumptions: explicit list if any

Deterministic Output Rules

• Use the same section order for every supported request of this skill.
• Keep output field names stable and do not rename documented keys across examples.
• If a value is unavailable, emit an explicit placeholder instead of omitting the field.

Completion Checklist

• Confirm all required inputs were present and valid.
• Confirm the supported execution path completed without unresolved errors.
• Confirm the final deliverable matches the documented format exactly.
• Confirm assumptions, limitations, and warnings are surfaced explicitly.
