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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.02934 |
| Opus 5.5 | $0.00022 | $0.01174 |
| Sonnet 5.5 | $0.00011 | $0.00587 |
| Haiku 4.5 | $0.00006 | $0.00293 |
Grade A, and why
ak-dev-code-quality 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 today.
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 — 300 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Quality & Contribution Conventions
Code Formatting
Agent Kernel uses black for formatting, isort for import sorting, and ruff for the typing rules only
(pyupgrade UP006/UP007/UP035/UP045; see Type annotations below).
Auto-format
# Format ak-py source and tests
make lint
# Format examples too
make lint-all
Check only (CI mode, no changes)
make lint-check # ak-py only
make lint-check-all # ak-py + examples
Auto-format a remote branch (CI)
To apply formatting on a remote branch without running the tools locally, trigger the
Lint and Commit GitHub Actions workflow (.github/workflows/lint-fix.yml) manually from the
Actions tab (workflow_dispatch). It takes two inputs:
lint_target: which Makefile target to run —lint,lint-examples, orlint-all(default).branch: the branch to format and commit the changes to.
The workflow runs the selected target and pushes a chore: commit with any formatting changes
back to the chosen branch. Protected branches (currently develop) are rejected before any
changes are made.
Configuration
In ak-py/pyproject.toml:
[tool.black]
line-length = 150
target-version = ["py312"]
[tool.isort]
profile = "black"
line_length = 150
[tool.ruff.lint]
select = ["UP006", "UP007", "UP035", "UP045"]
Examples have no ruff config of their own: the root Makefile runs uvx ruff over examples/ in
--isolated mode with the same rules (RUFF_VERSION/RUFF_RULES), so keep those in sync with ak-py.
In example projects, line length is 120:
[tool.black]
line-length = 120
target-version = ["py312"]
Type Checking
cd ak-py
uv run mypy src/
Configuration:
[tool.mypy]
python_version = "3.12"
warn_return_any = true
warn_unused_configs = true
disallow_untyped_defs = true
disallow_incomplete_defs = true
Commit Convention
Use Conventional Commits format:
<type>: <short description>
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.

ak-dev-code-quality is a skill published in the GitHub repository yaalalabs/agent-kernel (192 stars, last pushed yesterday), licensed Apache-2.0. It adds 55 tokens to every session and 2,934 once invoked, about $0.0002 per session on Opus 5.5. 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.
