gNMIBuddy: Instructions file for Codex

AGENTS.md

gNMIBuddy AGENTS.md is an instructions file for Codex, OpenCode from jillesca/gNMIBuddy. It costs 299 tokens per session, scanned A, original, BSD-3-Clause.

Repository instructions for gNMIBuddy, a Python command-line tool and server for querying network devices through gNMI, a standard protocol for reading and changing network configuration. They cover operational rules, testing, Python style, and design work.

In plain words
What is it for?
Use them when developing, testing, reviewing, or designing changes for gNMIBuddy. They specify how to run tests and commands, handle logs and SQL-like queries, organize Python code, and report blockers.
Why use it?
They prevent risky repository actions such as committing or pushing changes and make test results easier to inspect when terminal output is truncated. They also set consistent coding and security practices.

Written for Codex and OpenCode: the file is AGENTS.md.

This is jillesca/gNMIBuddy's own configuration. It tells Codex and OpenCode how to work on gNMIBuddy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything gNMIBuddy configures →

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

gNMIBuddy 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 1mo 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

gNMIBuddy — Project Instructions

gNMIBuddy is a Python CLI and MCP server for querying network devices via the gNMI protocol.

Operational Rules

These rules apply to all work in this repository without exception:

  • Never commit files — staging is reserved for the developer's workflow
  • Never push commits to any remote branch
  • Never merge a PR
  • To test the CLI: uv run ... and capture output to a log file, then inspect the file
  • Terminal output can be cut off, so always redirect CLI command output to a log file
  • Run tests with pytest from the terminal — the integrated test terminal can hang
  • If you find improvement opportunities while working on a task, note them on the issue
  • If you hit a blocker, document it in the issue thread and ask for help

Python Conventions

These apply to every Python file in this project:

  • Log entries must use lazy evaluation — f-strings inside logging calls are prohibited
  • Import statements must be grouped (standard library → third-party → local application), separated by blank lines, and placed at the top of each module

Coding and Design Work

When doing implementation, refactoring, code review, or object design work, load the sw-engineering skill for the full set of engineering principles (DRY, KISS, YAGNI, SOLID, object design, readability, and Martin Fowler's refactoring guidelines).

Changes

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.
