Command Sequence Ordering

command-sequence-ordering

Summary

Load and validate a CSV-based workflow specification into an ordered sequence of executable processing commands, preserving row order and command name validation. This skill ensures that SmartPeak can reliably reconstruct a default workflow from configuration files during session startup.

When to use

You have a workflow.csv file co-located with sequence.csv in a session directory, and you need to initialize a reproducible, ordered chain of processing steps (e.g., LOAD_RAW_DATA → MAP_CHROMATOGRAMS → EXTRACT_CHROMATOGRAM_WINDOWS → ZERO_CHROMATOGRAM_BASELINE → PICK_MRM_FEATURES → SELECT_FEATURES → STORE_FEATURES) without manual re-ordering or step omission.

When NOT to use

• Workflow commands are already loaded in memory as an ordered data structure — re-parsing the CSV would be redundant.
• The workflow.csv file is missing, malformed, or does not co-exist with the sequence.csv file — initialization will fail.
• You need dynamic workflow re-ordering or conditional branching at runtime; this skill enforces static, row-based ordering.

Inputs

• workflow.csv (comma-separated values file; each row contains a workflow_step command name)
• session directory path (co-located with sequence.csv)

Outputs

• ordered list of validated workflow step command names (e.g., [LOAD_RAW_DATA, MAP_CHROMATOGRAMS, EXTRACT_CHROMATOGRAM_WINDOWS, ...])
• command list ready for downstream workflow executor invocation

How to apply

Read workflow.csv from the session directory line-by-line. Extract the workflow_step command name from each row (e.g., 'LOAD_RAW_DATA', 'PICK_MRM_FEATURES'). Validate each command against the known set of supported workflow commands provided by SmartPeak. Construct an ordered list that preserves the exact row sequence from the file, rejecting or flagging invalid commands. Return the validated, ordered command list to the workflow executor, which then invokes each step sequentially. This approach ensures deterministic, reproducible workflow execution and guards against transposition errors or unsupported command invocation.

Evaluation signals

• Verify that the returned command list preserves the exact row order from workflow.csv (row 1 → position 0, row 2 → position 1, etc.).
• Confirm that all returned commands are members of the supported command set (LOAD_RAW_DATA, MAP_CHROMATOGRAMS, EXTRACT_CHROMATOGRAM_WINDOWS, ZERO_CHROMATOGRAM_BASELINE, PICK_MRM_FEATURES, SELECT_FEATURES, STORE_FEATURES, etc.).
• Check that invalid or unsupported commands are flagged, logged, or rejected without being added to the ordered list.
• Verify that the workflow executor successfully invokes each command in sequence without transposition, duplication, or omission.
• Confirm that workflow output (e.g., feature tables, QC reports, calibration curves) is generated in the expected sequence and location, indicating correct command ordering.

Limitations

• No changelog or discussion section content provided in the source material; edge cases or version-specific command compatibility are not documented.
• The skill assumes workflow.csv is well-formed CSV with a consistent schema; robustness to malformed or mixed-delimiter files is not specified.
• Row-based ordering is rigid; no support for conditional branching, loops, or dynamic re-ordering of commands at runtime.
• Validation is against a static set of known commands; new or user-defined commands would require schema extension, which is not described.
