verify-parameters

verify-parameters is a command for Claude Code from enricoros/big-AGI. It costs 10 tokens per session (989 once invoked), scanned A, original, MIT.

A command that checks whether language-model parameter definitions in code match values validated by the providers’ APIs.

In plain words
What is it for?
Use it after updating API sweep results or model definitions to verify supported parameters, allowed values or ranges, and function-calling support.
Why use it?
It catches mismatches that could make supported settings inaccurate or cause invalid requests. It can check one model provider or all four listed providers.

About the project

Big-AGI is an open-source workspace for using multiple AI models through chat and other AI functions. It is intended for engineers, founders, researchers, and other users who want to work with AI personas, model comparisons, image generation, voice, documents, and code-related features. The catalogue entries provide commands, instructions, and a skill for working with Big-AGI.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verify-parameters scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Verify LLM Parameters

Compare model parameterSpecs in definition files against API-validated sweep data.

If $ARGUMENTS provided, verify only that dialect, which includes reading the pair of sweep results and model defintions. Otherwise verify all five, and read the pairs in sequence.

Files

Sweep results (source of truth for select parameters):

  • tools/develop/llm-parameter-sweep/llm-{dialect}-parameters-sweep.json By the time you see these files, the repo owner has already updated them via tools/develop/llm-parameter-sweep/sweep.sh (very long running, 15 min per vendor).

Model definitions (source of truth for model defintions for the user and application, including constants, interfaces, supported parameters and sometimes allowed parameter values):

  • OpenAI: src/modules/llms/server/openai/models/openai.models.ts
  • Anthropic: src/modules/llms/server/anthropic/anthropic.models.ts
  • Gemini: src/modules/llms/server/gemini/gemini.models.ts
  • xAI: src/modules/llms/server/openai/models/xai.models.ts
  • Meta AI: src/modules/llms/server/openai/models/metaai.models.ts

Task

The sweep data is the source of truth for allowed model parameter values or value ranges, and for the fn function-calling capability probe.

For each model in the sweep, verify the model definition exposes exactly those capabilities - no more, no less. This includes:

  • The parameter is present in parameterSpecs
  • The paramId variant covers exactly the values from the sweep, if applicable
  • LLM_IF_OAI_Fn in interfaces matches "roundtrip" in the sweep's fn array (see below)
  • etc.

Report models where the definition doesn't match the sweep.

Parameter Mapping

Example parameter mapping. Note that new parameters may have been added to both the definition, and the sweep. The objective of the sweep is to hint at model definition values, but the model definitions are what matters for Big-AGI, and need to be carefully updated, otherwise thousands of clients may break.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

verify-parameters is a command published in the GitHub repository enricoros/big-AGI (7,111 stars, last pushed 2d ago), licensed MIT. It adds 10 tokens to every session and 989 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
