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 | $0.00936 | $0.00936 |
| Opus 5.5 | $0.00374 | $0.00374 |
| Sonnet 5.5 | $0.00187 | $0.00187 |
| Haiku 4.5 | $0.00094 | $0.00094 |
Grade A, and why
dev-starter-kit 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 1mo 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Project Instructions for AI Coding Agents
This file is automatically read by AI coding tools (Codex, Cursor, Claude Code, Copilot, Windsurf, etc.) to understand project conventions and act as a senior engineer.
Project Overview
This is a Python project. All source code lives in src/, tests in tests/, and documentation in docs/.
Build & Run
# Setup
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
pip install -e ".[dev]"
# Lint
ruff check . && ruff format --check .
# Fix lint issues
ruff check --fix . && ruff format .
# Run tests
pytest tests/ -v
# Pre-commit hooks
pre-commit install
pre-commit run --all-files
Code Style & Conventions
- Python 3.11+ required
- Ruff for linting and formatting (configured in
pyproject.toml) - Line length: 120 characters
- Quote style: double quotes
- Imports: sorted by isort (via Ruff)
- Type hints: use them on all public functions and method signatures
- Docstrings: use Google-style docstrings for public functions and classes
- No bare
except:— always catch specific exceptions - Prefer
pathlib.Pathoveros.path - Use f-strings over
.format()or%
Testing
- Test files go in
tests/with naming patterntest_<module_name>.py - Test classes:
Test<ModuleName> - Test methods:
test_<function_name>[_<scenario>] - Use
pytestfixtures for setup/teardown - Mock external dependencies (APIs, databases) — never make real network calls in tests
- Every PR that changes source files must include corresponding tests (enforced by CI)
Git & PR Workflow
- Branch from
main - Branch naming:
feat/description,fix/description,chore/description - Commit messages follow Conventional Commits:
feat:new featurefix:bug fixchore:maintenancedocs:documentationstyle:formatting (no logic change)refactor:code restructure (no behavior change)test:adding/updating tests
- PRs require passing CI checks before merge
- Squash merge to
main
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.

dev-starter-kit AGENTS.md is an instructions file published in the GitHub repository humzakt/dev-starter-kit (3 stars, last pushed 7mo ago), licensed MIT. It adds 936 tokens to every session, about $0.0037 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 2026-08-31.
