Ports the OpenClaw "search before answering" protocol to the Cursor and
Claude plugin surfaces so the agent reads the palace before answering
about past work, people, projects, or prior decisions instead of
guessing from model memory.
- integrations/shared/recall-protocol.md: single source of truth for the
recall protocol, referenced by the skill and the rule so they cannot
drift.
- skills/mempalace-recall/SKILL.md: recall-only skill (the mempalace
skill keeps setup/mine/status); cross-linked from the ops skill.
- rules/mempalace-recall.mdc: plugin recall rule, alwaysApply: false so
it only fires on recall-relevant turns and never adds MCP latency to
greenfield work.
- examples/cursor/rules/: opt-in copies for non-plugin users, including
an aggressive alwaysApply: true variant documented with its latency
tradeoff.
- .claude-plugin/skills/mempalace-recall/SKILL.md: Claude plugin parity.
- tests: assert the recall skill and rules/ discovery layout; the
shipped rule must be alwaysApply: false.
- docs: .cursor-plugin/README.md and the cursor-hooks guide now describe
the three layers of recall (hook + skill + rule).
The Antigravity plugin mirror lands as a follow-up on the antigravity
branch, where .antigravity-plugin/ exists.

Adds first-class Cursor IDE integration alongside the existing Claude
Code and Codex hook flows, so Cursor users get the same automatic
diary saves, pre-compaction transcript capture, and session-start
memory recall — without changing any default behaviour for existing
users.
What's included
---------------
Cursor hook scripts (hooks/cursor/):
- mempal_save_hook_cursor.sh — Stop event, counter +
loop_count guard, pending-save marker consumption, background
mempalace mine, followup_message emission.
- mempal_precompact_hook_cursor.sh — synchronous mine before
compaction, drops a pending_save marker, returns user_message.
- mempal_wake_hook_cursor.sh — sessionStart event,
wing-scoped recall guidance via additional_context.
- lib/common.sh — shared parsing + state helpers
(bash 3.2 safe, no heredoc-in-subshell traps).
- install.sh — idempotent installer with
--scope, --variant, --dry-run, --uninstall. Recognises existing
entries by basename so re-installs across paths work.
- STDIN_SHAPE.md, README.md — payload schemas + quick
reference.
Cursor plugin (.cursor-plugin/ + repo-root components):
- plugin.json, marketplace.json, README.md.
- skills/mempalace/SKILL.md — model-invocable skill mirroring the
Claude plugin's skill surface.
- commands/mempalace-{help,init,mine,search,status}.md — slash
commands for marketplace-published installs (filename = slug).
- mcp.json — auto-registers the mempalace MCP
server, wrapped under the documented mcpServers key.
Examples + docs:
- examples/cursor/hooks.json, hooks.minimal.json + README.
- website/guide/cursor-hooks.md + sidebar entry.
- README.md and CHANGELOG.md updates.
Tests (129 new, all green):
- tests/test_cursor_hooks_shell.py — 75 behavioural tests for
the three hook scripts: kill switches, input parsing, counter
logic, loop prevention, pending markers, wing inference, logging.
- tests/test_cursor_hooks_install.py — 19 contract tests for the
installer: dry-run, idempotent merge, basename-matched uninstall,
refusal to overwrite malformed JSON.
- tests/test_cursor_plugin_manifest.py — 35 contract tests for the
plugin: manifest validity, version sync with mempalace.version,
mcp.json shape, skill/command frontmatter, default-discovery
layout invariants.
Design notes
------------
- Local-first and zero-API by default; hooks never call external
services. Same privacy model as the existing Claude Code hooks.
- Fail-open: hook scripts deliberately do not use set -e so a broken
hook can never block the user's conversation.
- Cursor preCompact cannot block + return a followup, so we
synchronously mine the transcript and drop a pending_save marker
that the next stop hook consumes — guarantees verbatim capture
before context window compression.
- Cursor's default plugin discovery requires real commands/, skills/,
and mcp.json at the plugin root (verified against the cached
cloudflare plugin); .cursor-plugin/{commands,skills} are convenience
symlinks back to those canonical locations.
- bash 3.2 compatibility throughout: avoids heredoc-in-command-
substitution parser bugs; uses python -c for JSON parsing;
basename-matched entry recognition in install.sh.
- All changes are additive. No existing files are removed, no
existing hooks change behaviour, and no new runtime dependencies
are introduced.
