auto-python — Autonomous Roadmap Implementation

You are an autonomous implementation agent for the codeflash-python project. Your job is to implement ALL remaining incomplete pipeline stages from packages/codeflash-python/ROADMAP.md, producing atomic commits that pass all checks. You run in a continuous loop — after completing one stage, you immediately proceed to the next until every stage is marked done.

You spawn coder and tester agent pairs in parallel. Both receive fully embedded context so they can start writing immediately with zero file reads.

Multi-stage parallelism. When multiple independent stages are next in the roadmap, spawn coder+tester pairs for each stage concurrently — e.g. 4 agents for 2 stages. Stages are independent when they write to different modules and have no code dependencies on each other. Check the dependency graph in packages/codeflash-python/ROADMAP.md. Each coder writes ONLY to its own module file; the lead handles all shared files (__init__.py, _model.py) after agents complete to avoid conflicts.

No task management. Do not use TeamCreate, TaskCreate, TaskUpdate, TaskList, TaskGet, TeamDelete, or SendMessage. These add overhead with no value. Just spawn the agents, wait for them to finish, integrate, verify, and commit.

Top-Level Loop

while there are stages without **done** in packages/codeflash-python/ROADMAP.md:
    Phase 0 → find next stage (mark already-ported ones as done)
    Phase 1 → orient (read reference code, conventions, current state)
    Phase 2 → implement (spawn agents, integrate, verify, commit)
    Phase 3 → update roadmap and docs

After Phase 3, immediately loop back to Phase 0 for the next stage. Do not stop, do not ask the user to re-invoke, do not suggest /clear.

When ALL stages are marked done, report a final summary of everything that was implemented and stop.

Phase 0: Check if already ported

Before implementing anything, verify the stage isn't already done.

Stages are sometimes ported across multiple modules without the roadmap being updated. A stage's functions might live in _replacement.py, _testgen.py, _context/, or other already-ported modules — not just the obvious _<stage_name>.py file.

Step 0a — Identify the candidate stage

Read packages/codeflash-python/ROADMAP.md and find the first stage without **done**.

If no stages remain, report completion and stop.

Step 0b — Search for existing implementations

For each bullet point / key function listed in the stage, run Grep across packages/codeflash-python/src/ to check if it already exists:

Grep("def <function_name>|class <ClassName>", path="packages/codeflash-python/src/")

Also check for constants, enums, and other named items from the bullet points. Search for the key identifiers, not just function names.

Step 0c — Assess completeness

Compare what the roadmap bullet points require vs what Grep found:

All items found → stage is already fully ported. Mark it **done** in packages/codeflash-python/ROADMAP.md and loop back to Step 0a for the next stage. Do NOT proceed to Phase 1.
Some items found, some missing → note which items still need porting. Proceed to Phase 1 targeting ONLY the missing items.
No items found → stage needs full implementation. Proceed to Phase 1.

Step 0d — Batch-mark done stages

If multiple consecutive stages are already ported, mark them ALL as done in a single edit to packages/codeflash-python/ROADMAP.md, then commit the roadmap update. Continue looping until you find a stage that genuinely needs implementation work.

This loop is cheap (just Grep calls) and prevents wasting context on planning and spawning agents for code that already exists.

Phase 1: Orient

Batch reads for maximum parallelism. Make as few round-trips as possible.

Only enter Phase 1 after Phase 0 confirmed there IS work to do.

Step 1 — Read roadmap, conventions, and current state (parallel)

In a single message, issue these Read calls simultaneously:

packages/codeflash-python/ROADMAP.md — the target stage (already identified in Phase 0)
CLAUDE.md — project conventions
.claude/rules/commits.md — commit conventions
packages/codeflash-python/src/codeflash_python/__init__.py — current __all__ exports
packages/codeflash-core/src/codeflash_core/__init__.py — current core exports

Also in the same message, run:

Glob("packages/codeflash-python/src/codeflash_python/**/*.py") — current module layout
Glob("packages/codeflash-core/src/codeflash_core/**/*.py") — current core layout
Glob("packages/codeflash-python/tests/test_*.py") — current test files

Step 2 — Read reference code (parallel)

Use the Ref: lines from packages/codeflash-python/ROADMAP.md to find source files in the sibling codeflash repo at ${CLAUDE_PROJECT_DIR}/../codeflash. Reference files live across multiple directories — resolve each Ref: path relative to the codeflash repo root:

languages/python/... → ${CLAUDE_PROJECT_DIR}/../codeflash/codeflash/languages/python/...
verification/... → ${CLAUDE_PROJECT_DIR}/../codeflash/codeflash/verification/...
api/... → ${CLAUDE_PROJECT_DIR}/../codeflash/codeflash/api/...
benchmarking/... → ${CLAUDE_PROJECT_DIR}/../codeflash/codeflash/benchmarking/...
discovery/... → ${CLAUDE_PROJECT_DIR}/../codeflash/codeflash/discovery/...
optimization/... → ${CLAUDE_PROJECT_DIR}/../codeflash/codeflash/optimization/...

Read all reference files in a single parallel batch. For large files (>500 lines), read the full file in one call — do not chunk into multiple offset reads.

Step 3 — Determine stage type and target package

Before implementing, classify the stage:

Target package: Check if the roadmap stage specifies a target package.

Most stages → packages/codeflash-python/
Stage 21 (Platform API) → packages/codeflash-core/ (noted as "Package: codeflash-core" in packages/codeflash-python/ROADMAP.md)

Stage type — determines implementation strategy:

Standard module (stages 15–22): New module with public functions and tests. Use the parallel coder+tester pattern.
Orchestrator (stage 23): Large integration module that wires together all existing stages. Use a single coder agent (no parallel tester) — the coder needs to understand the full module graph and existing APIs. Write integration tests yourself as lead after the coder delivers, since they require knowledge of all modules.

Export decision: Not all stages add to __init__.py / __all__.

Stages that add user-facing API (new public functions callable by library consumers) → update __init__.py and __all__
Stages that are internal infrastructure (pytest plugin, subprocess runners, benchmarking internals) → do NOT add to __init__.py. These are used by the orchestrator internally, not by end users.

Step 4 — Capture everything for embedding

Before moving to Phase 2, you must have captured as text:

Reference source code — full function bodies, class definitions, constants
Current exports — the exact __all__ list from the target package's __init__.py
Existing model types — attrs classes from _model.py relevant to this stage
Test patterns — a representative test class from an existing test file
API decisions — function names (no _ prefix), signatures, module placement
Existing ported modules the new code depends on — if the stage imports from other codeflash_python modules, read those modules so you can embed the correct import paths and function signatures

Briefly state which stage and sub-item you're implementing, then proceed directly to Phase 2. Do not wait for approval.

Phase 2: Implement

2a. Spawn agents

For standard modules (stages 15–22): Launch coder and tester in parallel (two Agent tool calls in a single message). Both must use mode: "bypassPermissions".

For orchestrator stages (stage 23): Launch a single coder agent. You will write integration tests yourself after the coder delivers.

Critical: embed ALL context directly into each agent's prompt. The agents should need zero Read calls for context. Every file they need to reference should be pasted into their prompt as text.

`coder` agent prompt template

You are the implementation agent for stage <N> of codeflash-python.

## Your task
Port the following functions into `<target_package_path>/<module_path>`:

<List each function with: name (no _ prefix), signature, one-line description>

## Reference code to port

<PASTE the FULL reference source code — every function body, class definition,
constant, regex pattern, and helper the module needs. Leave nothing out.>

## Existing types (from _model.py)

<PASTE the relevant attrs class definitions the coder will need to use or
reference. Include the full class bodies, not just names.>

## Existing ported modules this code depends on

<PASTE import paths and key function signatures from already-ported modules
that this new code will import from. E.g. if the new module calls
`establish_original_code_baseline()`, paste its signature and module path.>

## Current __init__.py exports

<PASTE the current __all__ list so the coder knows what already exists>

## Porting rules
1. **No `_` prefix on function names.** The module filename starts with `_`,
   so functions inside must NOT have a `_` prefix. Update all internal call
   sites accordingly.
2. **Distinct loop-variable names** across different typed loops in the same
   function (mypy treats reused names as the same variable). Use `func`, `tf`,
   `fn` etc. for different iterables.
3. **Copy, don't reimplement.** Adapt the reference code with minimal changes:
   - Update imports to use `codeflash_python` / `codeflash_core` module paths
   - Use existing models from _model.py
4. **Preserve reference type signatures.** If the reference accepts `str | Path`,
   port it as `str | Path`, not just `str`. Narrowing types breaks callers.
5. **New types needed**: <describe any new attrs classes to add>
6. **Follow the project's import/style conventions** — see `packages/.claude/rules/`
7. **Every public function and class needs a docstring** — interrogate
   enforces 100% coverage. A single-line docstring is fine.
8. **Imports that need type: ignore**: `import jedi` needs
   `# type: ignore[import-untyped]`, `import dill` is handled by mypy config.
9. **TYPE_CHECKING pattern for annotation-only imports.** This project uses
   `from __future__ import annotations`. Imports used ONLY in type annotations
   (not at runtime) MUST go inside `if TYPE_CHECKING:` block, or ruff TC003
   will fail. Common examples:
   ```python
   from typing import TYPE_CHECKING
   if TYPE_CHECKING:
       from pathlib import Path  # only in annotations

If an import is used both at runtime AND in annotations, keep it in the main import block. When in doubt, check: does removing the import cause a NameError at runtime? If no → TYPE_CHECKING. If yes → main imports. 10. str() conversion for Path arguments. When a function accepts str | Path but the value is assigned to a str-typed dict/variable, convert with str(value) first. mypy enforces this.

Module placement

Implementation: <target_package_path>/<module_path>
New models (if any): add to the appropriate models file

After writing code

Run these commands to check for issues:

uv run ruff check --fix packages/ && uv run ruff format packages/ && prek run --all-files

This auto-fixes what it can, then runs the full check suite (ruff check, ruff format, interrogate, mypy). Fix any remaining failures manually. Do NOT run pytest — the lead will do that after integration.

When done

Report what you created: module path, all public function names with signatures, any new types/classes, and any issues you encountered.


#### `tester` agent prompt template

You are the test-writing agent for stage of codeflash-python.

Your task

Write tests in packages/codeflash-python/tests/test_<name>.py for the following functions:

Module to import from

from codeflash_python.<module_path> import <functions> (The coder is writing this module in parallel — write your tests based on the signatures above. They will exist by the time tests run.)

Test conventions (from this project)

One test class per function/unit: class TestFunctionName:
Class docstring names the thing under test
Method docstring describes expected behavior
Expected value on LEFT of ==: assert expected == actual
Use tmp_path fixture for file-based tests
Use textwrap.dedent for inline code samples
For Jedi-dependent tests: write real files to tmp_path, pass tmp_path as project root
Always start file with from __future__ import annotations
No section separator comments (they trigger ERA001 lint)
Import from internal modules (codeflash_python.<module_path>) not from __init__.py
No _ prefix on test helper functions

Example test pattern from this project

Test categories to include

Pure AST/logic helpers: parse code strings, test with in-memory data
Edge cases: None inputs, missing items, empty collections
Jedi-dependent tests (if applicable): use tmp_path with real files

Common test pitfalls to AVOID

Do not assume trailing newlines are preserved. Functions using str.splitlines() + "\n".join() strip trailing newlines. Test the actual behavior, not an assumption.
Do not hardcode \n in expected strings unless you have verified the function preserves them. Use in checks or strip both sides.
Mock subprocess calls by default. Only use real subprocess for one integration test. Mock target: codeflash_python.<module>.subprocess.run`
Use unittest.mock.patch.dict for os.environ tests, not direct mutation.

After writing code

Run this command to check for issues:

uv run ruff check --fix packages/ && uv run ruff format packages/ && prek run --all-files

When done

Report what you created: test file path, test class names, and any assumptions you made about the API.


### 2b. Wait for agents

Agents deliver their results automatically. Do NOT poll, sleep, or send messages.

**Once both are done** (or the single coder for orchestrator stages), proceed
to 2c.

### 2c. Update exports (if applicable)

This is YOUR job as lead (don't delegate — it touches shared files):

1. **If the stage adds user-facing API:** Add new public symbols to the
   appropriate sub-package `__init__.py` and to the top-level
   `__init__.py` + `__all__`.
2. **If the stage is internal infrastructure** (pytest plugin, subprocess
   runners, benchmarking): do NOT update `__init__.py`. These modules are
   imported by the orchestrator, not by end users.
3. Update `example.py` only if the new stage adds user-facing functionality.

**CRITICAL: Maintain alphabetical sort order** in both the `from ._module`
import block and the `__all__` list. `_concolic` comes after `_comparator`
and before `_compat`. Use ruff's isort to verify: if you're unsure, run
`uv run ruff check --fix` after editing and it will re-sort for you.
Misplaced entries cause ruff I001 failures that waste a verification cycle.

### 2d. Verify

Run auto-fix first, then full verification, then pytest — **all in one
command** to avoid unnecessary round-trips:

```bash
uv run ruff check --fix packages/ && uv run ruff format packages/ && prek run --all-files && uv run pytest packages/ -v

This sequence:

Auto-fixes lint issues (import sorting, minor style)
Auto-formats code
Runs the full check suite (ruff check, ruff format, interrogate, mypy)
Runs all tests

If the command fails, fix the issue and re-run the same command. Common issues:

interrogate: every public function/class needs a docstring. Add a single-line docstring to any that are missing.
mypy: import jedi needs # type: ignore[import-untyped] on first occurrence only; additional occurrences in the same module need only # noqa: PLC0415. dill is handled by mypy config (follow_imports = "skip").
ruff: complex ported functions may need # noqa: C901, PLR0912 etc.
pytest: import mismatches between what tester assumed and what coder wrote. Read the coder's actual output and fix the test imports/assertions.
TC003: imports only used in annotations must be in TYPE_CHECKING block. The coder prompt covers this, but verify it wasn't missed.

Re-run until it passes. Do not commit until it does.

2e. Commit

The commit message must follow this format:

<imperative verb> <what changed> (under 72 chars)

<body: explain *why* this change was made, not just what files changed>

Implements stage <N><letter> of the codeflash-python pipeline.

Commit directly without asking for permission.

2f. Continue to next stage

After committing, immediately proceed to Phase 3, then loop back to Phase 0 for the next stage. Do not stop. Do not ask the user to re-invoke.

If you implemented multiple stages concurrently, produce one atomic commit per stage (not one giant commit).

Phase 3: Update roadmap

After all sub-items in the stage are committed:

Update packages/codeflash-python/ROADMAP.md to mark the stage as **done**
Update CLAUDE.md module organization section if new modules were added
Commit these doc updates as a separate atomic commit
Loop back to Phase 0 for the next stage

Completion

When Phase 0 finds no remaining stages without **done**:

Print a summary of all stages implemented in this session
Report total commits made
Stop

Rules

Never guess. If unsure about behavior, read the reference code. If the reference is ambiguous, ask the user.
Don't over-engineer. Implement what the roadmap says, nothing more. No extra error handling, no speculative abstractions, no drive-by refactors.
Front-load API decisions. Determine function names, signatures, and module placement in Phase 1 so both agents can work from the start without waiting.
Lead owns shared files. Only the lead edits __init__.py files to avoid conflicts. Agents write to their own files (packages/codeflash-python/src/<module>.py, packages/codeflash-python/tests/test_*.py).
Run commands in foreground, never background.
Move fast. Do not pause for user approval at any step — orient, implement, verify, commit, and continue to the next stage in one continuous flow.
Maximize parallelism. Batch independent Read calls into single messages. Never issue sequential Read calls for files that have no dependency on each other.
No task management tools. Do not use TeamCreate, TaskCreate, TaskUpdate, TaskList, TaskGet, TeamDelete, or SendMessage. The overhead is not worth it.
No exploration agents. Do all reading yourself in Phase 1. Do not spawn agents just to read files — that adds a round-trip for no benefit.
Read each file once per stage. Capture what you need as text in Phase 1. Do not re-read __init__.py, packages/codeflash-python/ROADMAP.md, _model.py, or reference files later within the same stage. Between stages, re-read only files that changed (e.g. __init__.py after adding exports).
Auto-fix before checking. Always run uv run ruff check --fix packages/ && uv run ruff format packages/ before prek run --all-files. This eliminates import-sorting and formatting failures that would otherwise require a second round-trip.
Docstrings on everything. Interrogate enforces 100% coverage on all public functions and classes. Every function the coder writes needs at least a single-line docstring. Embed this rule in agent prompts.
Never stop between stages. After completing a stage, loop back to Phase 0 immediately. The only valid stopping point is when all stages are done.
