Could not find agent compaction prompts

Error message

Could not find agent compaction prompts

What it means

find_agent_prompts locates the agent package's compaction prompt directory by probing candidate paths relative to the repo root (packages/agent/src/compaction/prompts or agent/src/compaction/prompts). If none exist, the script raises this FileNotFoundError because snapcompact experiments require those prompt files to build compaction contexts.

Solutions

1. Run the script from within a full clone of the oh-my-pi monorepo containing packages/agent/src/compaction/prompts.
2. Set/verify the script's root detection (parent directory derivation) so candidates resolve — run with the correct cwd or adjust the parent logic.
3. Update the candidate list in find_agent_prompts if the prompts directory was relocated.
4. Ensure the path exists: ls packages/agent/src/compaction/prompts before running.

Example fix

# before
cd /tmp && python adapters/snapcompact.py ...   # FileNotFoundError
# after
cd /path/to/oh-my-pi && python packages/metaharness/src/adapters/snapcompact.py ...

import pathlib
root = pathlib.Path("packages/agent/src/compaction/prompts")
assert root.is_dir(), f"run from repo root; missing {root}"

try:
    prompts = find_agent_prompts()
except FileNotFoundError:
    sys.exit("snapcompact must run inside a full oh-my-pi checkout with packages/agent/src/compaction/prompts")

When it happens

Trigger: Running snapcompact.py outside a checkout of this repo, from a directory layout without the agent package (e.g. installed package, shallow copy, renamed/sparse checkout), or after the prompts directory was moved.

Common situations: Running the research adapter standalone on a machine without the full monorepo; running from a packaged/deployed copy where source dirs are absent; a refactor moved compaction prompts and the hardcoded candidates are stale.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
