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.
npx agentmods add instructions/robino16/codeembed/agents-mdgit clone --depth 1 https://github.com/robino16/codeembedWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00165 | $0.00165 |
| Opus 5 | $0.00082 | $0.00082 |
| Sonnet 5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
codeembed 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
Agent Instructions
Python Coding Standards
- Use
Union(fromtyping) instead of|. - Use
Optional[<type>]instead of<type> | None. - Strictly use type hints for all functions and methods.
- Run tests with
uv run --no-sync pytest(--no-syncflag is important).
General
When asked for a PR review, do a simple git diff against the main branch. Do not read PRs from GitHub. Do not use PR skill.
Codebase search
Use the mcp__codeembed__search tool as the first step for any question about how this codebase works — how something is implemented, where something is defined, what calls what. Prefer it over grep or file reads for exploratory questions.
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.

codeembed AGENTS.md is an instructions file published in the GitHub repository robino16/codeembed (4 stars, last pushed 3mo ago), licensed MIT. It adds 165 tokens to every session, about $0.0008 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 2026-08-31.
