ReMe/AGENTS.md

AGENTS.md

This file guides coding agents working in the ReMe repository. Keep changes small, testable, and consistent with the contracts already expressed by the code.

Project Principles

ReMe is a local-first, file-native memory system for agents.

• User-owned memory files are the source of truth.
• Indexes, caches, metadata, and generated state must be rebuildable.
• Prefer transparent formats and behavior over hidden state.
• Preserve user control over storage, configuration, and service boundaries.
• Keep concepts focused on project intent; let code and schemas describe implementation.

When a proposed convenience conflicts with these principles, favor data ownership, recoverability, and predictable behavior.

Sources of Truth

Use this order when documentation and implementation disagree:

1. Current code and public Pydantic schemas.
2. Tests that describe supported behavior.
3. CLI help and the built-in configuration.
4. Development documentation and historical notes.

Do not copy large implementation descriptions into documentation. Link to the relevant module or express the stable contract instead. If behavior changes intentionally, update the code, schema, tests, configuration, and concise documentation together as needed.

Repository Map

• reme/reme.py: CLI entry point and client/server dispatch.
• reme/application.py: application assembly, dependency ordering, and lifecycle.
• reme/config/default.yaml: built-in jobs, components, and defaults.
• reme/schema/: public and runtime Pydantic contracts.
• reme/components/: services, stores, clients, jobs, and component registration.
• reme/steps/: executable job steps.
• tests/unit/: primary fast validation suite.
• tests/integration/: tests that may require real credentials or services.
• tests/vector/ and tests/light/: specialized suites.
• plugins/reme/: Claude Code integration.
• skills/reme_memory/: skill that communicates with the ReMe service.
• skills/qwenpaw_memory/: separate direct-file memory convention; it does not call ReMe.
• docs/: pages and assets that support the repository README; not the deployed docs site.

Development Setup

ReMe requires Python 3.11 or newer.

pip install -e ".[dev,core]"

Before changing behavior, inspect the adjacent implementation, schemas, configuration, and focused tests. Follow existing patterns unless the task explicitly calls for a new contract or architecture.

Change Workflow

1. Identify the narrowest supported contract affected by the request.
2. Read the relevant implementation and tests before editing.
3. Make the smallest coherent change; avoid unrelated cleanup.
4. Update related schemas, defaults, registrations, and imports when required.
5. Add or adjust focused tests for observable behavior.
6. Run proportionate validation and report anything not run.

Component and step discovery depends on registration imports:

• Components use R.register(...) in reme/components/component_registry.py.
• Component packages must be reachable through reme/components/__init__.py.
• Step modules must be reachable through reme/steps/__init__.py.

Adding an implementation without its registration import can leave it undiscoverable at runtime. Treat the implementation, registry entry, and import side effect as one change.

Do not silently change stable CLI flags, configuration keys, workspace layouts, serialized schemas, or service interfaces. When such a change is required, preserve compatibility where practical and make the migration explicit.

Validation

Use the narrowest useful check while iterating, then broaden it according to risk.

Run a focused test:

pytest tests/unit/path/to/test_file.py -v

Run the main unit suite:

pytest tests/unit -v --tb=long -s --log-cli-level=WARNING

Run repository formatting and lint checks when the change warrants it:

pre-commit run --all-files

Formatting and lint configuration is authoritative. Python code currently uses a maximum line length of 120 for Black and Flake8, with Pylint also run by pre-commit.

Integration tests may contact real services and require credentials such as LLM_API_KEY or EMBEDDING_API_KEY. Do not run credentialed or externally mutating tests automatically. Run them only when the task requires them and the user has supplied or authorized the necessary environment.

Coding and Test Conventions

• Target Python 3.11+ and follow the surrounding typing and async style.
• Keep public schemas explicit and backward-compatible where practical.
• Close async clients, services, tasks, and other lifecycle resources deterministically.
• Prefer clear failures over silently falling back to corrupt or ambiguous state.
• Keep indexes and caches derivable from user-owned source files.
• Use tmp_path or another isolated temporary workspace in tests.
• Never write test state into the repository's .reme/ directory.
• Mock network or model boundaries in unit tests.
• Do not commit .env files, credentials, runtime memory, logs, indexes, or caches.

Documentation Boundaries

ReMe's local docs and the deployed documentation site have separate responsibilities.

• Keep docs/ focused on content and assets used by README.md and README_ZH.md.
• Preserve README-linked pages under docs/en/ and docs/zh/, including their relative paths, unless the README is updated in the same change.
• Keep README-required images under docs/figure/.
• Keep the README's main documentation index pointed at docs.agentscope.io or the agentscope-ai/docs repository, following the existing link style.
• Do not treat local README-supporting pages as the source for the deployed website.

The separate agentscope-ai/docs repository owns website content, navigation, versioning, and deployment. Public ReMe pages live there under reme/<version>/. Make website changes in that repository and follow its existing version-management conventions.

Do not add website build configuration or deployment workflows to ReMe unless the task explicitly changes this repository boundary.

Agent Guardrails

• Preserve unrelated user changes in a dirty working tree.
• Do not edit generated output when the source can be changed instead.
• Do not delete or rewrite user data to make a test pass.
• Avoid broad refactors unless they are necessary for the requested outcome.
• Do not introduce dependencies without a concrete need and repository-level justification.
• Treat network access, real credentials, and external service mutations as opt-in.
• State which validations passed and which were not run in the final handoff.

If a requirement is ambiguous, first infer intent from nearby code, tests, and schemas. Ask the user only when the remaining choice would materially alter a public contract, user data, or external system.
