Getting it into your agent
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00271 | $0.00271 |
| Opus 5 | $0.00135 | $0.00135 |
| Sonnet 5 | $0.00054 | $0.00054 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
opencode.nvim 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 yesterday.
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
AGENTS.md
Build, Lint, and Test
- Run all tests:
./run_tests.sh - Run a single test: Replace the directory in the above command with the test file path, e.g.:
./run_tests.sh -t tests/unit/test_example.lua
Code Style Guidelines
- Comments: Avoid obvious comments that merely restate what the code does. Only add comments when necessary to explain why something is done, not what is being done. Prefer self-explanatory code.
- Config: Centralize in
config.lua. Use deep merge for user overrides. - Types: Use Lua annotations (
---@class,---@field, etc.) for public APIs/config.
Dependency Topology Tool
Use scripts/dependency-topology/scan_topology.py to inspect and track architectural layering.
- Use
python3 scripts/dependency-topology/scan_topology.py scanto inspect current-state vs target-policy gap - Use
diffto inspect change direction (improved/regressed/neutral) between snapshots - Pass
--snapshot <git-ref>for historical snapshots - Pass
--jsonwhen feeding outputs into scripts or agents - Keep architecture cleanup discussions anchored on scanner output instead of ad-hoc grep chains
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.

opencode.nvim AGENTS.md is an instructions file published in the GitHub repository sudo-tee/opencode.nvim (932 stars, last pushed 10d ago), licensed Apache-2.0. It adds 271 tokens to every session, about $0.0014 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.
