Bump version to 3.5.0 across version.py, pyproject.toml, the Claude/Codex
plugin manifests, the README badge, and uv.lock. Refresh the "N MCP tools"
prose from 34 to 35 (delete_by_source #1729 and checkpoint #1851 each added a
tool). Add the 3.5.0 CHANGELOG entry.
Collapse the Cursor auto-save sequence (check_duplicate Nx + add_drawer
Nx + diary_write 1x) into a single mempalace_checkpoint MCP call so the
host UI renders one tool-call card and keeps its spinner up for the whole
save. The new tool reuses the existing single-item handlers, so semantic
dedup, idempotency, and verbatim guarantees are unchanged.
- mcp_server.py: add tool_checkpoint + register mempalace_checkpoint
- service.py: classify mempalace_checkpoint as a write tool
- cursor save hook: followup now drives one mempalace_checkpoint call
- docs: new mcp-tools.md section, help.md entry, 33 -> 34 tool count sweep
- tests: checkpoint add/dedup/malformed/registry + classify_tool

Address review feedback surfaced on the 3.4.1 release promotion (#1810).
Bug fix — `date -r FILE` is GNU-only. On BSD/macOS `date -r` expects
epoch seconds, not a path, so the staleness/throttle checks in the new
Cursor and Antigravity hooks silently failed on macOS: the state GC
swept on every fire and the pending-save guard was skipped. Replace
with a portable `os.path.getmtime` one-liner via the already-resolved
$MEMPAL_PYTHON_BIN (cursor/lib, antigravity/lib, antigravity save hook).
This restores the "bash 3.2.57 / macOS default" compatibility the
Antigravity changelog claims.
Docs:
- Correct the MCP tool count to 33 (was 19/29/31 in 21 places across
plugin manifests, READMEs, and website docs — all drifted from the
TOOLS dict / mcp-tools.md reference, which both have 33).
- Fix broken CHANGELOG link to the Cursor skill (skills/, not
.cursor-plugin/skills/).
- Fix one-too-many `../` in skills/mempalace/SKILL.md's cursor-hooks
link (resolved above the repo root).
- Add the required `mcpServers` wrapper to the mcp.json example in
.cursor-plugin/README.md so copy-paste yields a valid Cursor config.
Left intentionally unchanged: the os.dup2 fd-1 redirect in
mcp_server.py is deliberate (#225 keeps JSON-RPC off fd 1).
Resolves the maintainer review on the Cursor IDE support PR. Cursor-only
scope; cross-IDE items (wing-naming convention, shared-file merge order)
are coordinated on the separate Antigravity branch.
followup_message default (the one "decide before merge" item):
- Keep the stop-hook followup ON by default. Cursor's transcript format
is undocumented and mempalace/normalize.py has no Cursor parser, so the
background `mempalace mine --mode convos` is best-effort only and does
not yet yield clean verbatim drawers. The followup is therefore the
load-bearing verbatim-capture path; defaulting it off would leave a
default Cursor install capturing nothing.
- Add an opt-out (MEMPAL_CURSOR_SILENT=1, or MEMPAL_VERBOSE=false) for
users who want the Claude-style "zero tokens in chat" behaviour. The
hook still mines and keeps its counters/markers when silenced.
- Correct the misleading "background mine captures it" comments in the
save and precompact hooks; update hooks/cursor/README.md and the guide.
Hygiene fixes:
- Drop the hardcoded "version" field from .cursor-plugin/plugin.json and
marketplace.json (mempalace/version.py is the single source of truth);
tests now assert the field stays absent.
- Remove the committed .cursor-plugin/{commands,skills} symlinks (they
break on Windows clones with core.symlinks=false and were redundant
with the real repo-root components that `source: "."` already serves);
add a guard test that no symlinks exist under .cursor-plugin/.
- Document the preCompact synchronous-mine timeout tradeoff and that an
incremental/append-only mine is recoverable if killed (no corruption).
- Add a Cursor-namespaced, daily-throttled TTL sweep (MEMPAL_STATE_TTL_DAYS,
default 30) to lib/common.sh that GCs stale cursor_*.count/.pending only,
after the kill-switch check; shared logs and antigravity_* are untouched.
Verification: full suite green (2424 passed, 3 skipped), ruff check +
format clean, bash -n clean on all cursor scripts. +30 Cursor tests
(followup opt-out, state GC, TTL validation, no-symlink/version guards).

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.
