local_extract

local_extract is a command for Claude Code from jgt87/local-llm-mcp. It costs 17 tokens per session (387 once invoked), scanned A, original, MIT.

A command that pulls named fields from text and returns them as JSON, a structured format for data with named keys. It then checks that each extracted value really appears in the source.

In plain words
What is it for?
Use it to extract items such as names, dates, identifiers, or other fields from text, files, or command output.
Why use it?
It reduces manual copying from documents, command output, or conversation text and catches values invented or misread by the model. Missing fields are returned as empty values.

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

local_extract 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 5d 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.

What it actually says

Arguments: $ARGUMENTS

The first argument is the comma-separated field names; anything after it is the source. If the source is a file path, read the file. If it is a shell command, run it and use its output. Otherwise treat it as the text itself. With no source, use the most recent relevant text in this conversation.

Extract the fields with local_ask. Ask for a single JSON object with exactly those keys, null for any field not present, and no other text. Use temperature 0 and a maxTokens that fits the fields. Parse the reply; if it is not valid JSON, retry once with the parse error in the prompt. Then confirm each non-null value actually appears in the source. Set any that do not to null and say which.

Ground rules:

  • Use the local-llm tools for the generation step; do the reading, trimming and checking yourself. The local model has no file access, no repo context and no memory between calls, so every call must carry all the text it needs.
  • Keep maxTokens tight: locally it runs at roughly 16 tokens per second.
  • Stay on the default provider unless the user asked for OpenRouter. Never send secrets, keys or private data to provider="openrouter".
  • If a call fails because Ollama is unreachable, say so and stop; do not silently do the work yourself instead.
  • Treat the reply as a draft. Check it against the source before presenting it, fix what is wrong, and say briefly what you changed.

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.
