AGENTS.md

What this is

Producer-side tooling for MemPalace. Two thin wrappers in bin/ plus the companion agent skill. Pairs with the consumer-side mempalace skill.

Read ARCHITECTURE.md first — it's the canonical spec for what this repo does and why.

Structure

install.sh              # Idempotent installer — symlinks bin/* into ~/.local/bin
                        # and SKILL.md into ~/.agents/skills/opencode-mempalace-bridge/
ARCHITECTURE.md         # Canonical spec: diagrams, setup recipe, ops notes, upstream roadmap
README.md               # Human-facing quickstart + per-tool usage reference
SKILL.md                # Agent skill (symlinked into ~/.agents/skills/ on install)
bin/
  mempalace-docs        # Docs-only MemPalace miner (bash wrapper)
  mempalace-session     # Opencode session → MemPalace bridge (bash + inline Python)

Conventions

• Standalone executables in bin/ with #!/usr/bin/env bash shebang, no extension, chmod +x. Must work in non-interactive contexts (agent processes, cron, CI).
• Thin wrappers only. Neither tool reimplements the mempalace miner. Both follow the stage-to-cache-then-mine idiom: curate input to ~/.cache/…/<wing>/, then delegate to mempalace mine.
• Idempotent + dry-runnable. Every tool supports --dry-run. Second invocation on unchanged input is a no-op (dedup via source_file path, optionally + mtime).
• No external Python deps. Stdlib only (sqlite3, json, pathlib). Inline in the bash wrapper via heredoc.
• Argument parsing: --help/-h first, then mode flags, then positional args.
• Comment sections use # ── Section Name ────── style (matches sibling cli_utils repo).

Adding a new wrapper

A third wrapper would justify factoring a shared helper library. Until then, copy the pattern from mempalace-session (richest example):

1. Create bin/<name> with #!/usr/bin/env bash + chmod +x.
2. Implement --help, --dry-run, --repair flags (repair is opt-in; --no-repair kept as deprecated alias).
3. Stage to ~/.cache/<name>/<wing>/ with deterministic filenames.
4. Invoke mempalace mine ... (choose --mode convos if input is chat-like).
5. Do NOT end with mempalace repair unless --repair was explicitly passed. Repair is a destructive in-place HNSW rebuild and must never run on an unattended schedule.
6. Update README.md with usage + rationale.
7. Update install.sh? No — bin/* is auto-linked.
8. Update ARCHITECTURE.md if the wrapper fills a new architectural gap.
9. Update SKILL.md if agents should know when to invoke it.

Testing

Manual only. Integration-shaped:

# Smoke test — does it parse args and list what would happen?
./bin/mempalace-session --help
./bin/mempalace-session --dry-run

# Real test on a single session (safe, deterministic)
./bin/mempalace-session --session ses_<id> --dry-run
./bin/mempalace-session --session ses_<id>     # file into palace
mempalace_search "a phrase from that session"   # verify visibility
./bin/mempalace-session --session ses_<id>     # re-run → should skip

For mempalace-docs, test on a small repo (e.g. this one) first:

./bin/mempalace-docs "$PWD" --dry-run

Gotchas

• install.sh is idempotent but interactive — use --yes in non-interactive contexts.
• ~/.local/bin must be on $PATH. The installer warns if not.
• The companion skill lives at ~/.agents/skills/opencode-mempalace-bridge/SKILL.md and is a symlink into this repo. Editing that file edits SKILL.md here. To propagate to Claude Code / Kiro, run agents-sync from cli_utils.
• The opencode DB path defaults to ~/.local/share/opencode/opencode.db. Override via $OPENCODE_DB or --db.
• The mempalace miner skips symlinks (as of v3.3.3 — miner.py line ~828). That's why the wrappers use cp -p / explicit file writes for staging, not symlinks.
• The convos miner dedups on source_file path only (no mtime check). Staging filenames must be stable per session; deleting a staged JSONL forces a re-mine.
• The docs miner dedups on source_file path + mtime. That's why staging uses cp -p (preserves mtime).

Colocated skill pattern

This repo owns an agent skill (SKILL.md) that lives alongside the code it documents, rather than in a central skills repo like skillset. The advantages: the skill moves in lockstep with the wrappers it explains, one git clone gets you the full producer-side setup, and retirement (when upstream gaps close) removes skill + code + docs in one commit.

The convention for making this coexist cleanly with sibling tooling:

1. install.sh creates ~/.agents/skills/<name>/ as a real directory containing a SKILL.md symlink back into this repo. It does not create a dir-symlink, because real dirs are the signal that sibling reconcilers (skillset's deploy-skills.sh, cli_utils's agents-sync.zsh) should leave the dir alone.
2. install.sh drops a .skill-source marker file at the root of the skill dir:

   # skill-source: mempalace-toolkit
   # repo: <absolute path>
   # url: ssh://git@gitea.jordbo.se:2222/joakimp/mempalace-toolkit.git
   

   This is a breadcrumb for humans and future tooling — it answers "who owns this skill dir?" at a glance. deploy-skills.sh and agents-sync.zsh don't read it today (their existing logic already handles external dirs correctly) but may surface it in status reports later.
3. install.sh --uninstall removes the marker (only if it still says mempalace-toolkit) and the now-empty skill dir.

If you add a third colocated skill from a new repo, follow the same convention. The marker format is shared; only the repo name changes.

History

Split out from cli_utils on 2026-04-30. The wrappers originated there but the conceptual fit was weak (cli_utils is interactive shell tools; these are agent memory infrastructure). Some older diary entries and KG facts in the palace reference the original paths.
