Ship a launchd user agent plist alongside the existing systemd and
cron templates so macOS users can schedule mempalace-session without
falling back to cron. launchd is the macOS-native equivalent of a
systemd user timer: same scheduling model, same log conventions, same
single-instance guarantees.
- contrib/launchd/se.jordbo.mempalace-session.plist:
- Label uses reverse-DNS from the jordbo.se domain for consistency
with other user-installed launchd jobs; fork the prefix if reusing
this template in a different org.
- ProgramArguments points at /Users/USER/.local/bin/mempalace-session
(USER is substituted at install time, same pattern as
contrib/cron/).
- EnvironmentVariables.PATH covers ~/.local/bin, Apple Silicon
Homebrew, Intel Homebrew, and system defaults — launchd agents
get a minimal PATH by default and the wrapper needs to find
mempalace + python3.
- StartCalendarInterval matches systemd unit's schedule: Monday
03:00 local.
- RunAtLoad=false — load shouldn't trigger a run; schedule does.
- ProcessType=Background + LowPriorityIO=true + Nice=10 mirror
the systemd unit's Nice=10 + IOSchedulingClass=idle. macOS's
automatic App Nap and resource throttling for Background jobs
yields to interactive work cleanly.
- ExitTimeOut=7200 matches systemd's TimeoutStartSec=7200.
- StandardOut/ErrorPath under ~/Library/Logs/ so Console.app
surfaces them.
- contrib/README.md gains a full launchd section:
- Caveat table comparing to systemd (Persistent=true isn't quite
matched; RandomizedDelaySec has no equivalent; overlap prevention
is automatic).
- Install recipe using launchctl bootstrap (modern) with a fallback
note for legacy launchctl load -w on older macOS.
- Verify section shows launchctl list, launchctl print, log tails,
and launchctl kickstart for manual testing.
- Uninstall via launchctl bootout.
- Chooser table updated: macOS now explicitly points at launchd,
not cron.
- ARCHITECTURE.md §5, SKILL.md Quick automation pitch, and README.md
Keeping it fresh section all updated to mention the three scheduler
options and give per-platform quick-starts.
Plist XML validated with plistlib.
Until opencode session-stopping hooks land upstream, mempalace-session
is the entire mechanism that gets opencode conversations into the
palace — skip it and session history stays trapped in a local SQLite
DB, invisible to semantic search. Previous docs covered setup well
but were thin on when and how often to run it.
- ARCHITECTURE.md §5: replace the one-line 'When to re-mine' note with
a full Operational Routine section — triggers, cadence, relationship
to the session lifecycle, automation pointers, verification.
- SKILL.md: add an Operational Routine section aimed at agents —
when to suggest invoking the tool, cadence guidance, how to
distinguish this producer-side tool from the consumer-side
mempalace skill's in-session habits.
- README.md: add 'Keeping it fresh' subsection pointing at contrib/
and the full docs.
contrib/ ships three ready-to-use templates:
- systemd/mempalace-session.{service,timer} — user units with weekly
Mon 03:00 schedule, Persistent=true catch-up, RandomizedDelaySec for
fleet-wide jitter, ConditionPathExists guard for opencode-less boxes,
Nice+IOSchedulingClass=idle so it never fights interactive work.
- cron/mempalace-session.cron — sample crontab entry with log
redirection and clear USER-substitution instructions.
- README.md with install/verify/uninstall recipes for both, a chooser
table (systemd vs cron), container/devbox caveats, and tuning notes
(daily vs weekly vs monthly trade-offs).
The user's LATER-list item 'wrap mempalace-session in cron/systemd
timer for true auto-save coverage' is now actionable: a single
systemctl --user enable --now command stands it up.
Producer-side MemPalace tooling: two bash wrappers that bridge opencode
session history and project documentation into the palace. Originally
developed in cli_utils (2026-04-28); split into its own repo on
2026-04-30 because the conceptual fit was weak — cli_utils is
interactive shell tooling, while this is agent memory infrastructure
with its own architecture, dependency surface, and growth trajectory.
Contents:
- bin/mempalace-docs — docs-only mining wrapper (originally a2ddcc9 in
cli_utils), bridges the gap until MemPalace PR #1213 (exclude_patterns)
merges upstream.
- bin/mempalace-session — opencode → palace session bridge (originally
dacca0e in cli_utils). Reads ~/.local/share/opencode/opencode.db,
exports each session to Claude Code JSONL, mines via
'mempalace mine --mode convos'. Bridges the gap until opencode
session-stopping hooks + an opencode harness in hooks_cli.py land
upstream.
- ARCHITECTURE.md — canonical spec: architecture diagram, component
details, setup recipe, operational notes, upstream-retirement
roadmap. Originally a4cf314 in cli_utils.
- SKILL.md — companion agent skill (producer side). Pairs with the
consumer-side mempalace skill. Symlinked into
~/.agents/skills/opencode-mempalace-bridge/ by install.sh.
- install.sh — idempotent installer, also handles --uninstall.
- AGENTS.md — repo conventions.
History of the individual files is not preserved in this split; see
cli_utils (gitea.jordbo.se/joakimp/cli_utils) commits a2ddcc9, dacca0e,
and a4cf314 for the original authorship context.
