AGENTIC DIRECTIVE

Keep AGENTS.md and CLAUDE.md identical.

CODING ENVIRONMENT

• Install astral uv using "curl -LsSf https://astral.sh/uv/install.sh | sh" if not already installed and if already installed then update it to the latest version
• Install Python 3.14.0 stable using uv python install 3.14.0 if not already installed (requires uv >=0.9; see [tool.uv] required-version in pyproject.toml)
• Always use uv run to run files instead of the global python command.
• Current uv ruff formatter is set to py314 which has supports multiple exception types without paranthesis (except TypeError, ValueError:)
• Read .env.example for environment variables.
• All CI checks must pass; failing checks block merge.
• Add tests for new changes (including edge cases).
• Before pushing, prefer ./scripts/ci.sh (macOS/Linux) or .\scripts\ci.ps1 (Windows) to run the local CI sequence; requires uv on PATH. The local scripts run Ruff in repair mode (ruff format, then ruff check --fix) before type checking and tests.
• Use --only / --skip (PowerShell: -Only / -Skip) to run a subset when iterating; use --dry-run to print commands without running them.
• GitHub CI remains check-only for Ruff (ruff format --check, ruff check) so branch protection verifies committed code.
• Fall back to individual repair commands when debugging local failures: uv run ruff format, uv run ruff check --fix, uv run ty check, uv run pytest -v --tb=short. Use GitHub-style checks only when verifying enforcement locally: uv run ruff format --check, uv run ruff check.
• Do not add # type: ignore or # ty: ignore; fix the underlying type issue.
• Do not add from __future__ import annotations; Python 3.14 native lazy annotations are the project standard.
• All 5 check IDs are represented in scripts/ci.sh / scripts/ci.ps1 and enforced in tests.yml on push/merge (parallel jobs: suppression grep, ruff-format, ruff-check, ty, pytest).
• GitHub CI runs on push, pull_request, and merge_group so required checks validate merge queue candidates before they land.
• Repository protection should use rulesets: a non-bypassable main integrity ruleset requires pull requests, merge queue, required checks, and blocks direct/force pushes to main; a separate review ruleset may allow Alishahryar1/admins to bypass review only.
• Required status checks: set required status checks to all of those statuses (e.g. Ban suppressions and legacy annotations, ruff-format, ruff-check, ty, pytest—use the exact labels GitHub shows, which may be prefixed with CI /). Remove ci from required checks if it was previously added for the old gate job.

IDENTITY & CONTEXT

• You are an expert Software Architect and Systems Engineer.
• Goal: Zero-defect, root-cause-oriented engineering for bugs; test-driven engineering for new features. Think carefully; no need to rush.
• Code: Write the simplest code possible. Keep the codebase minimal and modular.

ARCHITECTURE PRINCIPLES

• Shared utilities: Put shared Anthropic protocol logic in neutral src/free_claude_code/core/anthropic/ modules. Do not have one provider import from another provider's utils.
• Failure ownership: Keep canonical failure semantics and redaction SDK-free in core/; providers alone classify SDK/HTTP failures and own retries; protocol/API adapters alone choose wire error types and commit-boundary serialization.
• DRY: Extract shared base classes to eliminate duplication. Prefer composition over copy-paste.
• Encapsulation: Use accessor methods for internal state (e.g. set_current_task()), not direct _attribute assignment from outside.
• Provider-specific config: Keep provider-specific fields (e.g. nim_settings) in provider constructors, not in the base ProviderConfig.
• Model-independent reasoning: Resolve client reasoning intent once at the application boundary; provider adapters translate documented provider capabilities. Never branch on upstream model names or versions to choose reasoning behavior.
• Dead code: Remove unused code, legacy systems, and hardcoded values. Use settings/config instead of literals (e.g. settings.provider_type not "nvidia_nim").
• Performance: Use list accumulation for strings (not += in loops), cache env vars at init, prefer iterative over recursive when stack depth matters.
• Platform-agnostic naming: Use generic names (e.g. PLATFORM_EDIT) not platform-specific ones (e.g. TELEGRAM_EDIT) in shared code.
• No type ignores: Do not add # type: ignore or # ty: ignore. Fix the underlying type issue.
• Python 3.14 annotations: Do not use from __future__ import annotations; rely on native lazy annotations and fix circular import boundaries instead of hiding them with annotation stringization.
• Imports: Prefer top-level imports. Avoid TYPE_CHECKING and local imports for first-party or required dependencies; if a top-level import creates a cycle, move shared types/protocols to a neutral owner.
• Complete migrations: When moving modules, update imports to the new owner and remove old compatibility shims in the same change unless preserving a published interface is explicitly required.
• Maximum Test Coverage: There should be maximum test coverage for everything, preferably live smoke test coverage to catch bugs early

COGNITIVE WORKFLOW

1. ANALYZE: Read relevant files. Do not guess.
2. PLAN: Map out the logic. Identify root cause or required changes. Order changes by dependency.
3. EXECUTE: Fix the cause, not the symptom. Execute incrementally with clear commits.
4. VERIFY: Run ./scripts/ci.sh or .\scripts\ci.ps1, plus relevant smoke tests when needed. Confirm the fix via logs or output.
5. SPECIFICITY: Do exactly as much as asked; nothing more, nothing less.
6. PROPAGATION: Changes impact multiple files; propagate updates correctly.
7. VERSION: If the commit touches production files on main, bump semver in the same commit (see Versioning).

VERSIONING (MAIN)

Every commit on main that changes a production file must include a semver bump in pyproject.toml in the same commit. Do not merge or push prod changes without updating the version.

Production files

These paths count as production (runtime, packaging, or install surface):

• src/free_claude_code/api/, src/free_claude_code/cli/, src/free_claude_code/config/, src/free_claude_code/core/, src/free_claude_code/messaging/, src/free_claude_code/providers/
• src/free_claude_code/application/
• .env.example
• pyproject.toml (dependencies, scripts, packaging)
• scripts/install.sh, scripts/install.ps1, scripts/uninstall.sh, scripts/uninstall.ps1, scripts/ci.sh, scripts/ci.ps1

These do not require a version bump on their own:

• tests/, smoke/
• Docs and assets: README.md, assets/, AGENTS.md, CLAUDE.md
• CI and repo config: .github/, .gitignore

If a single commit mixes production and non-production edits, still bump the version.

Semver rules

Use [project].version as MAJOR.MINOR.PATCH:

• PATCH (x.y.Z+1): bug fixes, refactors with no user-visible behavior change, dependency updates, packaging/install fixes.
• MINOR (x.Y+1.0): backward-compatible features—new providers, admin fields, CLI commands, config options, or behavior additions.
• MAJOR (X+1.0.0): breaking changes—removed or renamed env vars, incompatible API/CLI/default changes, or migrations users must act on.

When unsure between PATCH and MINOR, prefer PATCH for fixes and MINOR for new capability.

Required steps

1. Classify the change and choose the bump level.
2. Update version in pyproject.toml.
3. Run uv lock so uv.lock reflects the new package version.
4. Include the version and lockfile updates in the same commit as the production change.

Example commit on main after a packaging fix: bump 1.2.38 → 1.2.39, run uv lock, commit together with the fix.

SUMMARY STANDARDS

• Summaries must be technical and granular.
• Include: [Files Changed], [Logic Altered], [Verification Method], [Residual Risks] (if no residual risks then say none).

TOOLS

• Prefer built-in tools (grep, read_file, etc.) over manual workflows. Check tool availability before use.
