AGENTS.md

delx-agent-utilities AGENTS.md is an instructions file for Codex, OpenCode from davidmosiah/delx-agent-utilities. It costs 248 tokens per session, scanned A, original, MIT.

Project instructions for delx-agent-utilities, a stateless toolkit with many utility tools and MCP-compatible interfaces. Stateless means calls do not keep shared data between runs.

In plain words
What is it for?
Use them when adding or changing utility tools, command-line operations, MCP dispatch, schemas, documentation, and regression tests.
Why use it?
They set boundaries for safe changes, including no stored credentials or persistent module state, timeouts for network calls, and required tests.

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

delx-agent-utilities 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 7d 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

Agent Development Notes

Scope

delx-agent-utilities is a stateless, MCP-compatible toolkit. 90 utility tools + 3 agent-readiness surfaces (manifest / connection_status / privacy_audit).

Commands

  • Install: pipx install "delx-agent-utilities[mcp]" or pip install -e ".[dev,mcp]"
  • Test: pytest
  • CLI: delx-utils <subcommand> (manifest, status, privacy-audit, list-tools, show <tool>, call <tool> --json '{...}')
  • MCP server: delx-utils-mcp (stdio, FastMCP-based)

Rules for changes

  • Never add a tool that requires an API key, OAuth flow, or stored credential.
  • Never add module-level state (caches / counters / handles) between calls.
  • Networked tools must have an explicit per-call timeout (default 8s).
  • Add a regression test for every new tool in tests/test_dispatcher.py.
  • Keep schemas.py in sync with the dispatcher (_HANDLERS map) and the README tool list.
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.
