Summary

Two issues in the Claude Code plugin's skill (skills/mempalace/SKILL.md and mempalace instructions init output) prevent agent-driven use of the tool.

1. mempalace --version does not exist

skills/mempalace/SKILL.md (plugin v3.0.14) "Prerequisites" section:

mempalace --version

Actual CLI output:

usage: mempalace [-h] [--palace PALACE]
                 {init,mine,search,compress,wake-up,split,hook,instructions,repair,status} ...
mempalace: error: unrecognized arguments: --version

An agent following the skill's Prerequisites step hits exit code 2 immediately. Either add --version to the CLI or change the check to pip show mempalace / mempalace status.

2. mempalace instructions init tells agents to run mempalace init <dir> — which is interactive, so agents crash with EOFError

mempalace instructions init Step 5:

Run mempalace init <dir> where <dir> is the directory from Step 4.

Without --yes, mempalace init stops on an interactive prompt:

Your choice [enter/edit/add]: Traceback (most recent call last):
  ...
  File ".../mempalace/entity_detector.py", line 753, in confirm_entities
    choice = input("  Your choice [enter/edit/add]: ").strip().lower()
EOFError: EOF when reading a line

Issue #8 ("Non-interactive mode for all commands (agent-friendly)") was closed after adding --yes, but the skill instructions still don't use it. Since the skill is explicitly shipped for Claude Code (a headless agent), Step 5 should be mempalace init --yes <dir>.

3. Bonus — mempalace mine <project-dir> without prior init fails with no guidance

$ mempalace mine D:/.../vibeOps --wing vibeOps
ERROR: No mempalace.yaml found in D:/.../vibeOps
Run: mempalace init D:/.../vibeOps

mempalace instructions mine does not mention that project mining requires a prior init. An agent following the mine instructions only learns about this dependency from the error. Either auto-init when --yes is implied, or document the prerequisite in instructions mine.
