K. Hodges fa97abf0c3 Implemented deterministic diff generation via a new file_writer stage.
What changed:

  - Added file_writer stage support in nightshift/config.py:93, nightshift/agents.py:446, and nightshift/pipeline.py:374.
  - Added file-block parsing and deterministic patch generation in nightshift/patches.py:65.
  - file_writer agents now return complete file blocks:

    ```file:relative/path.py
    <complete file content>
    ```
    NightShift reads current files and generates the unified diff itself.

  - Existing patch_validator, patch_normalizer, and patch_apply still run after that.
  - Switched tiny-lisp-nightshift/nightshift.yaml:51 to type: file_writer.
  - Updated tiny-lisp-nightshift/agents/implementer.md:1 to request file blocks instead of diffs.
  - Updated README, tutorial, config reference, and design doc.

  Also added tests for parsing file blocks, generating multi-file diffs, validating those diffs, and running a full file_writer -> normalize -> validate pipeline.

  Verification: python -m unittest discover -v passes, 101 tests.

# NightShift Agent Input

## System Prompt

You are the planning agent for NightShift.

Create a concise implementation plan for the current task.

If you need repository context before planning, output lookup requests exactly like this:

lookup_requests:
- tool: read_file
  path: relative/path.py
- tool: grep
  path: .
  pattern: search_regex

After context is provided, write a short plan with:
- files to edit
- tests to add or update
- risks

Do not write code.

# Repo Tool Calls

## 1. read_file

Arguments:
- path: `lisp_parser.py`

Output:

```text
File not found: lisp_parser.py

2. read_file

Arguments:

  • path: tests/test_lisp_parser.py

Output:

File not found: tests/test_lisp_parser.py

3. list_files

Arguments:

  • path: .
  • pattern: *.py

Output:

lisp.py
tests/__init__.py
tests/test_lisp.py

4. grep

Arguments:

  • path: .
  • pattern: def parse\(

Output:

No matches found.

5. grep

Arguments:

  • path: .
  • pattern: class LispParser

Output:

No matches found.

Retry Notes

  • Repository lookup results have been provided. Write the final plan now; do not request more lookups.

Output Contract

Write the requested stage output in concise markdown.

If you need repository context before finalizing the plan, include: lookup_requests:

  • tool: list_files | read_file | grep path: pattern:

Use at most 5 lookup requests. Do not repeat the same lookup request. Prefer read_file for likely-relevant files over many grep variations. Do not search .nightshift, .git, virtualenvs, caches, or artifact directories.

NightShift will run these read-only lookup tools, save files-inspected.md, and re-run this planner stage with the retrieved context.
