Python
Summarize field presence and value types in JSON records with Python
Inspect a small JSON array of objects and report field coverage and top-level value type counts without printing the values.
Open recipe → Python · v0.1.0 · OriginalCompare two JSON objects and report changed paths with Python
Find added, removed and changed JSON object paths without fetching an API or altering either input.
Open recipe → Python · v0.1.0 · OriginalValidate CSV columns and detect duplicate rows with Python
Check required CSV columns and identify exact duplicate rows before an import.
Open recipe → Python · v0.1.1 · OriginalCalculate effective PumpSwap quote reserves from pool values
Given a PumpSwap pool's quote-vault token amount and signed virtual quote reserves, calculate and display the effective quote reserves used for quoting and pricing.
Open recipe → Python · v0.1.1 · OriginalCompare Local CSV Records by a Chosen Key
Compare two local CSV files using a CLI-selected key column and report keys that are added, removed, or present in both files with changed values, without modifying either file.
Open recipe → Python · v0.1.1 · OriginalValidate JSON Arguments in Saved XML Tool Calls
Read a local XML workflow and report tool-call elements whose `arguments` attribute is not valid JSON, without executing or modifying the workflow.
Open recipe → Python · v0.1.0 · OriginalCheck Local XML Workflow References
Read an XML workflow file and report elements whose `ref` attribute points to no declared `id`, without executing or modifying the workflow.
Open recipe → Python · v0.1.0 · OriginalInspect Agent Workflow Nodes in a Local XML File
Read a saved XML workflow file and print the tag names and attributes of elements selected by an exact tag name, without executing or modifying the workflow.
Open recipe →Rust
Audit Tabs in Saved Text
Read one UTF-8 text file or standard input and report the total number of tab characters, the number of lines containing at least one tab, and the one-based line numbers of those lines. Treat the input as read-only data; do not execute or modify it.
Open recipe → Rust · v0.1.0 · AdaptedCount Lines in a Local UTF-8 File or Standard Input
Create a Rust 2021 CLI that streams one UTF-8 file or standard input (`-`) and reports total, blank, and nonblank line counts. Propagate I/O and UTF-8 errors instead of silently truncating input.
Open recipe →JavaScript
Group HTTP(S) URLs by Hostname from a Local Text File
Read a UTF-8 text file or standard input, parse each nonempty line as an absolute HTTP(S) URL, and print a JSON object of hostname counts. Reject malformed lines without fetching any URL.
Open recipe → JavaScript · v0.1.0 · OriginalValidate Hexadecimal Event IDs and Find Duplicates
Read a JSON array of hexadecimal event ID strings from a UTF-8 file or standard input, validate each value, normalize valid IDs to lowercase without an optional leading `0x`, and report duplicate positions. Do not convert IDs to numbers or claim chain validity.
