atomicmemory-python AGENTS.md

Repository instructions for atomicmemory-python, a Python client library for the AtomicMemory memory service. They describe the project layout, required tools, supported coding practices, and files to read before making changes.

In plain words
What is it for?
Guiding work on the Python package, tests, examples, dependencies, HTTP clients, formatting, and strict type checking.
Why use it?
They give contributors the project-specific rules needed to make compatible changes and validate them consistently.

Token cost

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.

Security

Grade A, and why

atomicmemory-python 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.

atomicmemory-python — agent rules

Python client SDK for the AtomicMemory memory layer.

Contributor Context

Use this file as the repo-local contributor guide. When behavior depends on another AtomicMemory repo, rely on the published HTTP/package contract and call out any assumption in the PR.

Before changing code, read the relevant local files first:

  • README.md for user-facing installation and usage.
  • pyproject.toml for supported Python versions, dependencies, and tool config.
  • atomicmemory/ for package code and tests/ for expected behavior.

Repository Shape

  • atomicmemory/ — typed Python package.
  • tests/ — unit and integration tests.
  • examples/ — public usage examples.
  • pyproject.toml — package metadata and tool configuration.

Tooling

  • Package management: uv sync (NOT uv pip install).
  • Python interpreter: .venv/bin/python. Never the global python.
  • HTTP: httpx (sync Client, async AsyncClient).
  • Validation: pydantic>=2.7. jsonschema only when validating against external JSON schemas.
  • Lint/format: ruff (line=120). ruff format --check . is part of pre-commit.
  • Types: mypy --strict.
  • Dead code / static health: vulture --min-confidence 90. The whitelist file .vulture_whitelist.py MUST be included in every invocation (it allowlists Protocol-method parameter names and context-manager dunder args). Use the [tool.vulture] config (uv run vulture) or pass it explicitly: uv run vulture atomicmemory tests .vulture_whitelist.py --min-confidence 90. fallow is TypeScript-only and is not part of this repo's verification.
  • Tests: pytest, pytest-asyncio, pytest-mock, respx. Integration tests gated behind -m integration.

Code rules

  • File ≤400 lines (excl. comments/docstrings); function ≤40 lines (excl. catch/finally and docstrings); test files ≤400 lines; tests ≤40 lines.
  • Google-style docstrings (Args:, Returns:, Raises:).
  • Module docstring at the top of every file. For modules that port a specific TS file, include the TS source-of-truth path ("""Port of atomicmemory-sdk/src/.../foo.ts.""").
  • No fallback values; no os.getenv in business code (config flows through Pydantic models constructed at startup).
  • No silent except. No bare except:.
  • Greenfield code — no backwards-compat hacks, no _ private renames for "removed" code.
  • Snake_case for Python attributes; Pydantic Field(alias="apiUrl") aliases preserve TS camelCase wire format.
  • Keep public API behavior aligned with atomicmemory-sdk where both SDKs expose the same concept.
  • Prefer integration tests with a real HTTP path for client behavior; use mocks only for narrow transport errors.

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.

atomicmemory-python AGENTS.md is an instructions file published in the GitHub repository atomicstrata/atomicmemory-python (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 778 tokens to every session, about $0.0039 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.
