jurisd AGENTS.md

jurisd AGENTS.md is an instructions file for Codex, OpenCode from russellbrenner/jurisd. It costs 625 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for jurisd, a tool for Australian legal research with source tracking and provenance, meaning evidence showing where information came from. They cover its command and MCP interfaces.

In plain words
What is it for?
Use them when adding or modifying CLI or MCP commands, documenting arguments and outputs, checking compatibility, or working on the command registry.
Why use it?
They prevent agents from describing the tool inaccurately or changing its public commands without the required contract details.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

jurisd AGENTS.md 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.

Agent instructions for jurisd

Purpose

jurisd is a source-backed Australian legal research and provenance instrument over a governed command surface. It exposes legal research capabilities through MCP, CLI, and future TUI adapters.

Do not describe jurisd as a chatbot, oracle, AI companion, or autonomous legal advice system.

Current foundation architecture

Current files:

  • src/server.ts registers the current MCP tool surface.
  • src/cli.ts handles CLI entry before the server starts.

Foundation PR 1 is introducing planned command-surface governance files:

  • src/commands/types.ts will define command contract and authority metadata types.
  • src/commands/contracts.ts will provide the command contract registry for CLI/docs/future adapters.
  • docs/MCP-COMPATIBILITY.md will record the MCP compatibility set once present.

Command contract rule

Foundation PR 1 is introducing the command contract registry. Once present, add commands once through that registry.

Every public command contract needs:

  • stable command id
  • synopsis
  • summary
  • arguments
  • flags
  • stdin mode
  • output modes
  • exit codes
  • validation schema reference or adapter mapping
  • stability level
  • side-effect class
  • terminal safety policy
  • capability gates
  • result contract

Adapter-specific metadata is required when that adapter is enabled.

Until the registry exists, command surface changes must preserve MCP compatibility and update tests and docs together.

MCP surface rule

MCP tools are curated. Do not expose operator, install, update, destructive, filesystem-write, or network-write commands over MCP unless a later authority decision explicitly permits it.

Existing MCP tool names are compatibility-sensitive. Update docs/MCP-COMPATIBILITY.md once present. Before then, update the MCP tool-surface tests before changing the tool surface.

Security invariants

  • No secrets in code, docs, logs, tests, command output, or examples.
  • No shell execution with user-controlled strings.
  • Treat CLI args, TUI input, MCP input, provider output, source text, filenames, URLs, and completion candidates as untrusted.
  • Keep stdout for primary output and stderr for diagnostics.
  • JSON and NDJSON output must not contain terminal decoration.
  • Terminal output must strip or neutralise unsafe ANSI, OSC, control characters, and bidi controls when it renders untrusted text.

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.
