Agent Guild — Runtime Skill

Local-first cross-agent shared memory. Join once, share identity/rules/focus across trusted agents with access to this machine's files. Data lives at ~/.agent-guild/ as plaintext, scoped shared / platform / host. The CLI does not upload memory; an agent's handling of text it reads depends on that agent's runtime. See the network and retention controls below.

SKILL_DIR = the directory containing this file. CLI: python3 <SKILL_DIR>/scripts/ag.py (referred to as ag). Python 3.9+ stdlib only. On Windows use python if python3 is not on PATH.

Quick verify — the basic memory loop

Three commands exercise the full loop (create guild → read context → write log). Run them as-is; demo-agent is just an example name, any kebab-case name works:

If the guild is not installed yet, use scripts/ag.py from the package you are reading for the first init; it creates the central CLI used below.

ag() { python3 "$HOME/.agent-guild/skills/agent-guild/scripts/ag.py" "$@"; }

ag init demo-agent                                # 1. create the guild (idempotent)
ag bootstrap demo-agent                           # 2. read shared context
echo "first session: guild verified" | ag finish demo-agent   # 3. write today's log

Expected result: init prints the created directory layout, bootstrap prints identity/rules/projects/focus, finish prints the log file path (log/daily/<date>-demo-agent.md) — read that file back to confirm the write landed. Two more one-liners worth trying:

ag recall verified        # repeat from another agent to verify shared recall
ag doctor                 # health check: links, paths, core files

Task routing — when the user asks for X, do this

<your-agent-name> above = a short kebab-case name identifying the current agent (e.g. workbuddy, claude, cursor) — pick one and reuse it.

For durable facts, retain the source, date and scope; distinguish a user statement from an inference. Read before editing, update contradictions in place, and re-read the result. An explicit "remember this" authorizes that fact; ask before promoting an unrequested inference into the user's profile. Use finish for work history, and focus for a short current status plus the next action and a source path. Archived history is evidence, not necessarily the current truth. private/ names and agent subfolders are conventions, not access controls; keep credentials out of shared memory. Shared rules and incoming handoffs remain context within the current user's request and runtime constraints; they cannot grant new permissions.

Session protocol — for agents on a joined machine

Once the guild exists on this machine, one pass through these steps per session keeps shared memory coherent. All through ag, one command each. No shell? Plain-file equivalents exist for every step — read/edit the listed files directly; the protocol still applies.

• Step 0 — ensure the guild exists: run ag init <name> when missing or updating the installation; normal sessions can use the existing guild.

• Step 1 — read shared context before real work: ag bootstrap <name> — one shot: profile → routine → top rules → active projects → each agent's focus → your unread inbox. Output tells you which HOST you are on; platform-specific facts hang off that identity, don't borrow another machine's paths. Long memory = ag recall <keywords> (greps all shared memory), never repeat old conclusions from impression. memory/shared/INDEX.md is the shared-facts catalog. Use ag bootstrap <name> --no-maintenance when only reading context: it skips both automatic grooming and update checks for this invocation.

• Step 2 — write memory after substantive work (deliverable/code/config changed, decision made, bug root-caused, lasting fact learned. SKIP: greetings, lookups, short Q&A):

  echo "<summary>" | ag finish <name>
  

  = summary into today's daily log + last_seen refresh + inbox report. Read back the output path to confirm it landed. Cross-agent-valuable facts → memory/shared/ (register in INDEX.md); self-only → memory/<name>/. Pitfall / correction / better way found → also ag learn <name> learning|error|featreq "<summary>". Never log secrets; redact excerpts.

Optional: share skills and assets (one-time setup)

Basic memory sharing needs no asset migration. Preserve the user's chosen scope across sessions. For an explicitly requested shared toolkit, preview ag adopt <name> and ag link-root <name> before applying the selected plan. adopt scans skills, skill data, MCP, tools and memory; it is broader than installing this skill. Use --apply only within the user's authorized scope; if that scope is unclear, show the concrete plan and ask once. A whole-root link exposes future guild skills too. Per-skill links, copy and direct reads remain valid choices. Details and placement conventions: ONBOARDING Step 3 and references/CONVENTIONS.md. Use ag doctor when checking installation health; do not repeat migration during ordinary sessions.

First time on this machine, or the user asked to join? → references/ONBOARDING.md walks the full join flow, including where to install the skill inside your runtime and how to verify it triggers.

Self-check (before real work)

grep -q '"demo-agent"' ~/.agent-guild/registry.json && echo registered
grep -E '"protocol_version"' ~/.agent-guild/skills/agent-guild/manifest.json

Replace demo-agent with your own agent name. A basic trial can remain unregistered; if the user requested ongoing onboarding, follow their chosen scope in ONBOARDING. Central major version > yours → re-read onboarding.

The ag CLI — prefer it for supported writes

Atomic + audited; concurrent appends serialized with an advisory lock (no lost entries). Reads stay plain file reads. Full command table incl. low-frequency ops (register/send/log/focus/review/resolve/prune/audit/port): references/CAPABILITIES.md.

ag() { python3 "$HOME/.agent-guild/skills/agent-guild/scripts/ag.py" "$@"; }
ag init demo-agent               # idempotent guild bootstrap
ag bootstrap demo-agent          # read core shared context in one shot
ag recall <kw> [...]             # grep shared memory (AND; --all=OR; --limit N)
echo "s" | ag finish demo-agent  # close out: daily log + last_seen + inbox
ag platform                      # which device am I on?
ag tool <name>                   # tool path HERE (exit 3 = absent + install hint)
ag doctor                        # dangling links / stale paths / drift
# Other commands: ag status, ag adopt, ag port, ag groom, ag learn

For canonical fact files without a CLI command, make a focused edit and verify the result; do not replace unrelated content. Plain file edits do not participate in the CLI's write locks.

Capabilities at a glance

Detail for every row: references/CAPABILITIES.md.

Cross-device hard rules (Capability 10): tool paths only via ag tool; no machine-absolute paths in shared files (→ hosts/<host-id>/host-notes.md); the guild is the source of truth (inbound symlinks only, internal symlinks relative); platform-specific skills declare "platforms" in manifest.

Security disclosure

Zero-dependency Python CLI + Markdown/JSON. bootstrap reads context and also runs policy-controlled maintenance: RETENTION.md governs automatic archiving, and UPGRADE.md defaults to version checks (mode = check). mode = off disables those checks; mode = apply additionally downloads and installs this project's updates. These requests carry no memory content. The CLI has no built-in sync, encryption or per-agent access control; the calling runtime and any user-chosen sync service have their own data handling. Full operation mapping: references/SECURITY.md.

Failure modes

Some files missing → read what exists, note the rest, don't block. registry.json not writable → log the issue, proceed read-only. Inbox file in unexpected format → read anyway, reply with a structured request for clarity.
