Design and review caller-facing names and contracts: functions, tools, commands, CLI flags, parameters, config keys, env vars, profiles, event types, and node/edge identifiers. Check names, descriptions, help, docstrings, schemas, defaults, bounds, units, errors, outputs, mutation, and whether values reach behavior. Use when asked to "name a parameter", "parameter naming", "name this tool or command", "choose a flag, option, or config key", "design an options object", "one tool or two…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Function Signature and Parameter Guidance <purpose> A tool or parameter has four visible parts: its **name**, the **description** that teaches it, the **error** when a caller gets it wrong, and the **behavior** matching all three. Callers are increasingly AI agents reading a schema once and guessing, so merely *not wrong* still produces wrong calls. Aim for text that makes the wrong call hard to write, and behavior that fails loudly when it happens anyway. **The failures that matter most return success** — a parameter validated, clamped, echoed, and never used looks correct at every observable layer. So verify behavior matches the text (Group B passes) before checking the text is right (Group A). **An example gets read as the whole universe rather than as one case of a general principle.** That is true of the caller reading your description and of you reading these checks, so the words must state the concept explicitly — examples alone are not enough. Make the concept behind the concept explicit, or it is missed entirely. **Apply this to this document too:** every case named below is one instance of its rule, never the rule's limit. </purpose> <workflow> ## The Process …

How to install
mdr add ahundt/autorun/function-signature-and-parameter-guidance@sha256:a5a0b82972269b17The line at the top of this page pins the label git:20260816.05745f8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
