Three Claude-Code-inspired primitives for runPlannerLoop, derived from the
reverse-engineering reports in docs/reports/:
1. **Policy gate** (@mana/tool-registry) — evaluatePolicy() gates every tool
dispatch: denies admin-scope, denies destructive tools not in the user's
opt-in list, rate-limits per tool (30/60s default), flags prompt-injection
markers in freetext without blocking. Wired into mana-mcp with a
per-user rolling invocation log and POLICY_MODE env (off|log-only|enforce,
default log-only). mana-ai uses detectInjectionMarker only — tool dispatch
there is plan-only, so rate-limit/destructive checks don't apply yet.
2. **Reminder channel** (packages/shared-ai/src/planner/loop.ts) — new
reminderChannel callback in PlannerLoopInput. Called once per round with
LoopState snapshot (round, toolCallCount, usage, lastCall); returned
strings wrap in <reminder> tags and inject as transient system messages
into THIS LLM request only. Never pushed to messages[] — the Claude-Code
<system-reminder> pattern that keeps the KV-cache prefix stable.
3. **Parallel reads** (loop.ts) — isParallelSafe predicate enables
Promise.all dispatch when every tool_call in a round is parallel-safe,
in batches of PARALLEL_TOOL_BATCH_SIZE=10. Any non-safe call downgrades
the whole round to sequential. messages[] always appends in source
order, never completion order, so the debug log stays linear.
Default-off (undefined predicate) preserves pre-M1 behaviour.
Tests: 21 new in tool-registry (policy), 9 new in shared-ai (5 parallel,
4 reminder). All 74 green, type-check clean across 4 packages.

Foundation for autonomous Claude-driven testing. Plan:
docs/plans/mana-mcp-and-personas.md.
New packages
- @mana/tool-registry — schema-first ToolSpec<InputSchema, OutputSchema>
with zod generics, scope ('user-space' | 'admin') and policyHint
('read' | 'write' | 'destructive'). sync-client helpers speak the
mana-sync push/pull protocol directly so RLS and field-level LWW are
preserved. MasterKeyClient fetches per-user MKs via the existing
mana-auth GET /api/v1/me/encryption-vault/key endpoint (JWT-gated,
ZK-aware, already audited) — no new service-key endpoint built.
ZeroKnowledgeUserError surfaced as a typed throw.
- @mana/shared-crypto — AES-GCM-256 primitives extracted from the web
app's $lib/data/crypto/aes.ts so the server-side tool handlers and the
browser produce byte-for-byte identical wire format
(enc:1:{b64(iv)}.{b64(ct)}). Web app aes.ts now re-exports from
shared-crypto — 5 existing importers unchanged, svelte-check stays
green.
New service
- services/mana-mcp (:3069, Bun/Hono) — MCP Streamable HTTP gateway.
JWKS auth against mana-auth, per-user session isolation (session-id
belongs to the user who opened it — cross-user access returns 403),
admin-scoped tools filtered out before registration. MasterKeyClient
cached per process with a 5-minute TTL.
11 tools registered
- habits.{create,list,update,archive}, spaces.list (plaintext, M1)
- todo.{create,list,complete}, notes.{create,search}, journal.add
(encrypted — field lists match
apps/mana/apps/web/src/lib/data/crypto/registry.ts verbatim)
Infra
- Port 3069 added to docs/PORT_SCHEMA.md
- services/mana-mcp/CLAUDE.md with architecture, auth model,
tool-authoring recipe, local smoke-test steps
- Root CLAUDE.md services list updated
Type-check green across shared-crypto, mana-tool-registry, mana-mcp.
svelte-check on apps/mana/apps/web stays at 0 errors / 0 warnings.
Boot smoke verified: /health returns registry.loaded=true, unauthed
/mcp → 401, invalid-JWT /mcp → 401 with descriptive message.
Decisions locked in for later milestones (per plan D1–D10):
- Personas will be real mana-auth users (users.kind='persona'), no
service-key bypass (D1, D2)
- Tool-registry is the SSOT; mana-ai and the legacy
apps/api/src/mcp/server.ts get merged into it in M4 (three current
parallel tool catalogs collapse to one)
- Persona-runner (:3070) will be a separate service using the Claude
Agent SDK + MCP client (D5)
