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 | $0.00505 | $0.00505 |
| Opus 5 | $0.00253 | $0.00253 |
| Sonnet 5 | $0.00101 | $0.00101 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
SkillOpt 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent instructions for SkillOpt
Project identity
- Treat this repository as a local-first, open-source SkillOpt fork.
- SkillOpt optimizes skill documents / system prompts, not model weights.
- Prefer examples and smoke tests that work against a local OpenAI-compatible backend.
Default example workflow
When you need a runnable example, default to the bundled DotNetDebug setup:
- config:
configs/dotnetdebug/local_mitko.yaml - sample data:
data/dotnetdebug/tasks.json - seed skill:
skillopt/envs/dotnetdebug/skills/initial.md - output root:
outputs/dotnetdebug_smoke
Use small validation runs before suggesting larger experiments. Prefer overrides like:
--cfg-options \
train.num_epochs=1 \
train.batch_size=2 \
gradient.minibatch_size=2 \
gradient.analyst_workers=1 \
env.workers=1 \
env.limit=2
Documentation expectations
- Put the local AI path first in docs and examples.
- Mention cloud backends only as optional alternatives unless the task is explicitly cloud-specific.
- When referring to local inference, prefer
openai_compatandhttp://localhost:8000/v1unless the user says otherwise. - Keep the README aligned with
.env.exampleand the shipped configs.
Repo hygiene
- Never commit secrets,
.envfiles, private notes, personal scratch files, local outputs, or benchmark dumps. - Keep private markdown in ignored files such as
*.local.mdor*.secret.md. - Keep IDE state, virtual environments, logs, and generated outputs out of git.
- Before publishing, verify that
.gitignorestill covers local-only files.
Code and config conventions
- Prefer structured config sections:
model,train,gradient,optimizer,env. - Reuse repo-native configs instead of inventing ad hoc command lines when possible.
- If adding a new backend, update the backend modules, config mapping, runtime dispatch, docs, and env template together.
- If adding a new benchmark, update the env package, config, CLI entry points, and user-facing docs together.
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.

SkillOpt AGENTS.md is an instructions file published in the GitHub repository mitkox/SkillOpt (83 stars, last pushed 3mo ago), licensed MIT. It adds 505 tokens to every session, about $0.0025 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.
