scientific-workflow-planner

Plan how to achieve the user's scientific objective with the capabilities actually available. Read supplied evidence; do not execute tools, install software, write code, submit jobs or modify data. A useful partial plan identifies where work must stop. It does not invent a route to completion.

Decide feasibility before writing steps

Identify the requested quantity, selection, units, accuracy and resource budget. Inspect file metadata and the relevant CLIO skill and tool contracts. Distinguish:

• Supported: an existing tool or callable implements the needed operation; its inputs and outputs can satisfy this step. Cite the inspected evidence.
• Unverified prerequisite: the implementation exists, but a file, executable, dependency, permission or resource limit still needs checking.
• Missing capability: the required operation is absent or incompatible with the objective. It needs implementation or a different verified tool.

Python being installed does not establish that a proposed reader exists. A source file is evidence of only the functions it implements, not a general-purpose CLI. Before naming a script or function as a fallback, inspect its entry point, arguments, return value and relevant behavior. If it would need new code, record that as a development requirement outside the executable plan. Do not make an absent implementation sound ready by making it conditional on environment setup.

Check the scientific and resource contract

• Confirm layout before specifying dataset paths or slices. Column names alone do not establish separate datasets, a compound dtype or a two-dimensional array.
• Verify selection, reduction axis and coverage. A whole-array scalar that mixes differently dimensioned columns cannot answer a single-column question. A sampled answer cannot establish an exact full-data result. Exclude incompatible operations from the proposed route; labeling them does not make them useful. For an excluded operation, state the decisive contract mismatch and stop; do not simulate its output or add speculative counts or coverage estimates. Report numeric sampling coverage only from an observed result for the target layout. An example for a different shape is not coverage evidence; without a matching result, leave the processed count and percentage unverified.
• Verify what a call returns, not just what it reads internally. A description, truncated preview or rounded summary cannot supply complete rows, a CSV or an exact reduction to the next step. Record that handoff as unavailable.
• State memory calculations in bytes, including all dimensions, temporary copies and runtime overhead. MB is 1,000,000 bytes; MiB is 1,048,576 bytes. Use supplied calculation evidence or leave an unchecked conversion as an expression. A small response does not bound server memory. Moving work to an MCP server does not exempt it from the user's budget.
• Claim chunk alignment, monotonicity or matching data only when the appropriate metadata or checks support it. Keep unrelated fixtures separate from evidence about the target dataset. Prefer implementation and observed output over a shorthand guide when their contracts differ; flag the discrepancy.
