TL;DR

Multi-agent Claude Code crews share one persistent brain via 116 MCP tools: memory + semantic recall, real-time messaging, tasks, missions, and a fix-pattern KB. Backed by Convex (real-time DB + vector search). Deploy on Railway in under 10 minutes, or self-host on free Convex tier.

Deploy on Railway (1-click)

Deploy on Railway

Deploy your own VantagePeers MCP server in 1 click. Auto-configures CONVEX_URL + healthcheck + public HTTPS endpoint. Free Convex tier sufficient for solo + small-team deployments. See vantagepeers.com/docs for the full quick-start guide.

Backend: Convex

VantagePeers runs on Convex — a real-time database with serverless functions, vector search, and built-in cron. CONVEX_URL in your environment points to a specific Convex deployment.

Three deployment paths:

1. Free self-host (recommended for solo + small teams) — deploy your own Convex project:

   git clone https://github.com/vantageos-agency/vantage-peers.git
   cd vantage-peers && bun install
   npx convex dev      # creates a new Convex deployment under your account
   

   The Convex free tier covers solo + small-team coordination usage. Your CONVEX_URL is the deployment URL printed by npx convex dev.

2. Hosted cloud (consume our fleet deployment) — point CONVEX_URL to our managed Convex prod (compassionate-goldfinch-737.convex.cloud). Subject to fair-use quotas; intended for evaluation. Production use should self-host or upgrade to Pro Support.

3. Pro Support (dedicated deployment) — dedicated Convex instance with SLA, multi-tenant isolation, and priority support. Contact [email protected] for setup.

For any path, the MCP server is identical (npm install -g vantage-peers-mcp then vantage-peers-mcp to start) — only the CONVEX_URL differs.

One Convex deployment. One MCP server process per agent. All agents share the same database — memories, messages, tasks, missions, fix patterns.

Why VantagePeers?

Run multiple Claude Code agents and every session starts blind. No shared context. No coordination. Work duplicated. Mistakes repeated. VantagePeers fixes this:

Without VantagePeers	With VantagePeers
Each agent starts blind	Agents recall shared knowledge via semantic search
No communication between agents	Real-time messaging (broadcast, DM, channels)
Work gets duplicated	Task tracking with dependencies and assignees
Mistakes get repeated	Fix-pattern KB with semantic lookup before debugging
No coordination	Mission-based multi-step workflows

Quick Demo

Agent A stores a fact:

{ "namespace": "global", "type": "project", "content": "API uses FastAPI with SQLAlchemy ORM", "createdBy": "alice" }

Agent B recalls it 3 days later:

{ "query": "what framework does the API use", "namespace": "global" }

Returns:

"API uses FastAPI with SQLAlchemy ORM" (score 0.91, type=project, createdBy=alice)

Agent A pings Agent B directly:

{ "from": "alice", "channel": "bob", "content": "Schema is ready. Start on the API endpoints." }

Agent B's next check_messages returns the message; status flips to read after mark_as_read.

Pagination & envelope safety (Day-114 doctrine)

Every list_* MCP tool in VantagePeers follows one canonical pagination contract. The driver: Claude Code's tool-response cap is ~60 KB. A list_memories call against a busy namespace easily blows past that with full-row payloads, so every list tool ships with strict defaults (limit default 20, hard cap 200) and an opt-in fields="lite" projection that returns only 4–6 fields per row. Callers paginating large result sets always combine fields="lite" + cursor iteration.

The canonical envelope contract is fleet-wide and non-negotiable:

interface ListEnvelope<T> {
  items:       T[];     // projected rows (lite or full)
  nextCursor?: string;  // present IFF there are more pages; absent when done
}

nextCursor is an opaque base64url token — callers must not parse it. The format may evolve (TTL, signature). To iterate, pass the returned nextCursor back as the cursor arg on the next call. When the field is absent, the caller MUST stop. There is no separate isDone flag in the wire format — absence of nextCursor IS the done signal.

Concrete cursor loop (works identically for list_tasks, list_memories, list_episodes, list_messages, every list_*):

async function drainList(tool: string, args: Record<string, unknown>) {
  const all: unknown[] = [];
  let cursor: string | undefined;
  while (true) {
    const res = await mcpCall(tool, { ...args, fields: "lite", limit: 100, cursor });
    const envelope = JSON.parse(res.content[0].text) as { items: unknown[]; nextCursor?: string };
    all.push(...envelope.items);
    if (!envelope.nextCursor) break;
    cursor = envelope.nextCursor;
  }
  return all;
}

// usage
const allOpenTasks = await drainList("list_tasks", { assignedTo: "sigma", status: "open" });

Forbidden patterns (each caused a Day-114 production incident): reading .page instead of .value from Convex paginate() returns (silent items: []), returning a flat array instead of {items, nextCursor} envelope, silent MAX_LIMIT clamp without nextCursor (caller stuck at page 1), per-tool divergent MAX_LIMIT constants, and envelope-coverage tests that only check wrapper shape (hasProperty("items") passes on items: []). Every list_* test MUST use the seeded-data assertion pattern (items.length === N) — wrapper-shape-only assertions are banned.

Full doctrine: projects/vantage-peers/mcp-tools-standard-doctrine-v1.md (Sections 1–6: pattern obligatoire, anti-patterns, coverage matrix, fleet cross-reference, compliance gate, migration playbook). Cross-MCP fleet runbook: VR runbook mcp-tools-standard-pagination-doctrine (id kd750j7z7tqre6hxqmfsa8s9ed89erng). Day-114 audit matrix: projects/vantage-peers/mcp-pagination-audit-day114.md — 18 list_* tools audited (15 LOW, 2 HIGH fixed in PR #978, 1 documented EXCEPTION).

Day-114 fixes

• PR #978 (squash 0db28d5) — list_memories + list_episodes silent items:[] fix. Root cause: handler read memories?.page instead of the actual Convex paginate return field memories.value ({ value, continueCursor, isDone }). The bug silently returned empty arrays on EVERY call regardless of seeded data — not only on subsequent pages. Present since the original paginationOpts wiring (S3.3 B8, v2.5.0). Fixed via the canonical handler pattern (extract .value, encode continueCursor via encodeCursor, emit {items, nextCursor}). Shipped as [email protected] on npm.
• PR #980 (squash d09fc5b) — MCP Tools Standards doctrine v1 landed at projects/vantage-peers/mcp-tools-standard-doctrine-v1.md. Cross-MCP fleet canonical — every VantageOS MCP server (vantage-peers-mcp, vantage-registry-mcp, vCRM, doc-forge, architect, composer, frameworks) inherits the same list_* contract, anti-pattern ban list, and seeded-data test gate. Sister MCPs (Omega VR first) re-brick on this doctrine to eliminate divergence.

Prerequisites

• Node.js 18+ (20+ recommended for the MCP server)
• Convex account — free tier works (convex.dev)
• OpenAI-compatible API key — for text-embedding-3-small embeddings (used via AI Gateway or direct OpenAI)

Quick Start

Option A — stdio (local process, recommended for single-machine use)

# 1. Clone
git clone https://github.com/vantageos-agency/vantage-peers.git
cd vantage-peers

# 2. Install
bun install

# 3. Start the Convex dev server (creates a new deployment on first run)
npx convex dev

# 4. Set environment variables in Convex dashboard (Settings → Environment Variables)
#    AI_GATEWAY_API_KEY   — OpenAI-compatible key for text-embedding-3-small
#    BEARER_SECRET_MASTER — random 32+ char secret (generate: openssl rand -hex 32)
npx convex env set AI_GATEWAY_API_KEY=your-openai-api-key
npx convex env set BEARER_SECRET_MASTER=$(openssl rand -hex 32)

Configure MCP in your Claude Code settings (~/.claude.json):

{
  "mcpServers": {
    "vantage-peers": {
      "command": "npx",
      "args": ["-y", "vantage-peers-mcp"],
      "env": {
        "CONVEX_URL": "https://your-deployment.convex.cloud",
        "BEARER_SECRET": "your-bearer-secret-master-value"
      }
    }
  }
}

Replace your-deployment with the URL printed by npx convex dev. Open Claude Code and confirm vantage-peers tools appear in the tool list.

Option B — HTTP/SSE (Railway or any public endpoint; required for Claude.ai, ChatGPT, Codex)

VantagePeers Cloud runs an HTTP MCP server (server-http.ts) via the Streamable HTTP transport. Deploy to Railway in one click:

Deploy on Railway

Once deployed, the public endpoint is https://your-app.up.railway.app/mcp. Add to Claude.ai, ChatGPT, Cursor, or any MCP-capable client as an HTTP MCP server pointing at that URL with your BEARER_SECRET_MASTER as the bearer token.

See vantagepeers.com/docs/cloud/connect for per-client copy-paste config snippets.

Hero Features

Top 5 capabilities, in order of impact:

1. Semantic memory + recall — store typed facts; retrieve by meaning via 1536-dim vector search (text-embedding-3-small). Hybrid search (vector + BM25 + RRF fusion) available.
2. Inter-agent messaging — real-time channel/DM/broadcast routing with per-recipient read receipts. Multi-instance aware (route to a role or a specific instance).
3. Task + mission orchestration — typed task lifecycle with dependencies, atomic checkout_task for multi-instance conflict safety, missions for multi-step workflows (configurable templates: IRP, repo-fix, new-feature).
4. Fix-pattern KB — every validated bug fix becomes a searchable pattern (symptom → root cause → fix). search_fix_patterns_by_semantic BEFORE debugging cuts repeat-mistake rate.
5. Proactive error monitoring — hourly cron polls Convex deployments for new errors, dedups, auto-files GitHub issues. MTTR dropped from 4-day median to 28 minutes on the VantageOS fleet.

All features (click to expand) — grouped by category

Memory & knowledge

• Semantic memory with typed entries (user, feedback, project, reference, episode)
• Memory graph relations (updates, extends, derives) with automatic versioning (isLatest)
• Episodic learning records (context / goal / action / outcome / insight + severity)
• Fix-pattern knowledge base with semantic search and per-attempt logging
• Hybrid search (vector + BM25 with Reciprocal Rank Fusion)
• Knowledge Base document ingest (generate_upload_url → store_document_chunked) — mint a signed upload URL, POST the binary, then the document is chunked, embedded, and scheduled for RAG sync per chunk at write time, so uploaded documents are searchable via recall/hybrid_search alongside other memories

Coordination

• Inter-agent messaging (channels, role DMs, instance DMs, broadcast)
• Per-recipient read receipts on broadcasts (list_broadcast_status)
• Task management with priorities, dependencies, atomic claim (checkout_task)
• Mission planning with configurable multi-step templates
• Recurring tasks (cron-based templates that auto-create on schedule)
• Mandates (cross-agent service requests with budget tracking)

Operations

• Agent profiles (static identity + dynamic session state)
• Multi-instance support (same role, many concurrent instances)
• Diary entries (daily per-agent journals)
• Briefing notes (shared topic discussions with decisions)
• Component registry (agents, skills, hooks, plugins — full content backup)
• Business unit registry (BUs with strategy, pricing, KPIs, management fees)

External integration

• GitHub issue tracking synced via webhooks with status lifecycle + fix verification
• External issue tracking on third-party repos
• Hourly PR-monitoring cron (notifies on merge/close)
• Orchestrator signatures (automated VantageOS Team branding on commits/PRs/comments)

Observability

• Proactive error monitoring across Convex deployments
• Daily MTTR statistics with before/after VantagePeers eras
• Mission templates: IRP (13 steps), repo-fix (10 steps), new-feature (10 steps)

Security & multi-tenant scope

VantagePeers Cloud (multi-tenant) and Self-host both share the same OAuth 2.1 + scope enforcement core. The following controls form the v2.12.0 security baseline.

OAuth 2.1 hardening — D6 + D7 + D8

• D6 — confidential client_secret at /token — mcp-server/server-http.ts L382-585. Confidential clients (issued at DCR) must present client_secret on every token exchange. Comparison uses crypto.timingSafeEqual (constant-time) to eliminate length/early-exit oracles. Public clients (no secret at registration) continue PKCE-only. Refusal returns invalid_client per RFC 6749 §5.2. Shipped PR #621, commit 5fd6354.
• D7 — redirect_uri exact-match at /authorize — mcp-server/server-http.ts L298-376. The authorization endpoint rejects any redirect_uri that is not byte-identical to one of the URIs registered for the client_id. No prefix match, no host-only match, no scheme normalization. Hard error before any consent screen. Shipped PR #621, commit 5fd6354.
• D8 — DCR redirect_uris validation at POST /register — mcp-server/server-http.ts L333-405. Rejects absent, empty-array, non-string, unparseable, non-https (except http://localhost / http://127.0.0.1 for dev), and fragment-bearing URIs with invalid_redirect_uri (RFC 7591 §3.2.2). Defense-in-depth: Convex layer enforces the same guard in registerPublicClient. Closes zombie-client class. Commit 2f3e653.

Emergency tenant maintenance — patchScopeProfileEmergency

convex/oauth.ts exposes patchScopeProfileEmergency, a master-token-gated mutation for tenant rename / scope-profile rewrite. Guarantees:

• D4 — no global wildcard in cloud- profiles* — the mutation refuses to write * into any scope of a cloud-* profile.
• D9 — cascade rename — when a scope profile key is renamed, every existing oauth_clients row referencing the old key is cascade-updated.
• Cascade-revoke tokens — all oauth_tokens issued under the old key are revoked atomically with the rename.
• Append-only audit ledger — every invocation writes an oauth_audit_log entry (action, actor, before/after snapshot, timestamp). The ledger is append-only; no update or delete path exists.

Shipped PR #622, commit 9a1b8cf. Full D9 cascade-update across oauth_clients reached enforcement parity in PR #623, commit 2f5c974.

S3.1 — scope-aware filter framework (D3) — Waves A + B

mcp-server/src/scope-filter.ts is the single chokepoint that translates the caller's OAuth scope set into a row-level filter applied to every multi-tenant list/get path. The framework is wired into:

• list_memories, get_memory
• list_briefing_notes
• list_messages
• list_peers

Wave A (initial surface) shipped PR #624, merged at main 251d183. Wave B (extended surface) is tracked in PR #625.

oauth_audit_log — append-only emergency-action ledger

convex/schema.ts defines oauth_audit_log as an append-only table. Every emergency mutation (patchScopeProfileEmergency, future master-gated paths) writes a row capturing actor, action, before/after, and timestamp. No mutation path updates or deletes existing rows. This is the auditable record of every out-of-band tenant operation.

Convex-layer authorization — withOrgScope fail-closed step

convex/lib/auth.ts's withOrgScope now fails closed by default when no Clerk identity is present (previously fail-open to master/wildcard access); a per-call-site allowNoIdentityMaster opt-in preserves the old behavior for audited internal call sites. Four client-facing handlers (memories.listMemories, memories.getMemory, messages.listByChannel, diary.list) are now org-scoped, and the MCP legacy bearer path no longer leaves guards unenforced. This closes one fail-open gap — it is a step, not the completion of the multi-tenant model, which remains tracked separately. Full detail, auth-surface table, and open follow-ups: docs/cloud/security-multi-tenant.md §7.

Doctrine separation — Cloud vs Self-host

VantagePeers Cloud (multi-tenant SaaS) and VantagePeers Self-host are two distinct products. Runbooks are split: Cloud operations live under docs/cloud/, Self-host operations under docs/getting-started/. Security controls above apply to both products; tenant-specific cascade and audit semantics are documented in docs/cloud/security-multi-tenant.md.

List query projection + filters

list_bus — envelope safety (PR-A)

list_bus received strict defaults and an actual fields=lite projection in PR-A (branch feat/vpmcp-a-list-bus-envelope, commit a7ac41c), extending the S3.3 B8 follow-up batch 1 cursor rollout (which gave list_bus opaque cursor support) with hardened defaults and real projection logic:

• Default limit: 20 (was 50). Cap: 200 (was unbounded).
• fields='lite': projects to {_id, _creationTime, name, status, orchestratorId} — was a no-op since v2.4.12 (accepted the arg without applying projection). PR-A activates the actual server-side projection.
• Envelope: returns { items, nextCursor } (was flat array). nextCursor is null on the last page, opaque string otherwise.
• Cursor: encodes {creationTime, id} to survive same-millisecond inserts.

Full reference: list_bus — MCP Tools Reference.

Same envelope safety pattern will apply to list_components (PR-B) and list_repo_mappings (PR-C).

list_components — envelope safety (PR-B)

list_components received strict defaults and an actual fields=lite projection in PR-B (branch feat/vpmcp-b-list-components-envelope, commit 39f8d08), reusing the shared mcp-server/src/paging.ts helper introduced in PR-A:

• Default limit: 20 (was 100). Cap: 200 (was unbounded).
• fields='lite': projects to {_id, _creationTime, name, type, team} — was a no-op (returned full row). PR-B activates the actual server-side projection.
• Envelope: returns { items, nextCursor } (was flat array). nextCursor is null on the last page, opaque string otherwise.
• Cursor: encodes {creationTime, id} to survive same-millisecond inserts. Hybrid decode preserves S3.3 B8 {createdBefore} cursors.

Full reference: list_components — MCP Tools Reference.

list_repo_mappings — envelope safety (PR-C)

list_repo_mappings received strict defaults and an actual fields=lite projection in PR-C (branch feat/vpmcp-c-list-repo-mappings-envelope, commit 4ddca2b), reusing the shared mcp-server/src/paging.ts helper introduced in PR-A:

• Default limit: 20 (was 50). Cap: 200 (was unbounded).
• fields='lite': projects to {_id, _creationTime, repo, orchestrator, project} — excludes active, lastDeployedSHA, lastDeployedAt. PR-C activates the actual server-side projection.
• Envelope: returns { items, nextCursor } (was flat array). nextCursor is null on the last page, opaque string otherwise.
• Cursor: encodes {time, id} to survive same-millisecond inserts. Hybrid decode preserves S3.3 B8 {createdBefore} cursors.

Full reference: list_repo_mappings — MCP Tools Reference.

list_tasks — excludeAutoGenerated filter (PR-E)

list_tasks gained a new optional excludeAutoGenerated: boolean arg in PR-E (branch feat/vpmcp-e-list-tasks-exclude-cron, commit 74dea44):

• When true: filters tasks where createdBy matches /^cron-/i (dash mandatory — cron-bot filtered, cronus not) OR title matches /^\/?check-messages$/i (whole-string, case-insensitive, optional leading slash).
• Default false: returns all tasks unchanged — fully backward-compatible.
• Trade-off: post-filter pages may be smaller than limit (filtered rows do not count toward limit). Acceptable — cron catalog is small.

Example — Pi queue cleaned of cron-spam (152 cron tasks, audit §13):

list_tasks assignedTo="pi" status="open" excludeAutoGenerated=true limit=50

Full reference: list_tasks — MCP Tools Reference.

Bulk operations — bulk_complete_tasks (PR-F)

bulk_complete_tasks bulk-closes tasks that match a filter in one atomic mutation. Introduced in PR-F (commit 8eaa893) to safely drain cron-spam backlogs.

Safety: dryRun defaults to true. Always preview first, then call again with dryRun=false to commit. Closed tasks are irreversible — status permanently set to done.

// Step 1 — preview (dryRun=true is default)
bulk_complete_tasks filter={autoGeneratedOnly:true} callerOrchestrator="system"
// → { count: 152, sampleIds: ["k17...", ...], bulkRunId: "bulk-1782050000000-a3f2" }

// Step 2 — commit (explicit dryRun=false)
bulk_complete_tasks filter={autoGeneratedOnly:true} dryRun=false callerOrchestrator="system"
// → { count: 152, sampleIds: ["k17...", ...], bulkRunId: "bulk-1782050000000-a3f2", executedAt: 1782050000000 }

Caveats:

• Post-filter shrink: the filter predicate is applied in-memory against all non-done tasks; the matched set may be smaller than expected when combined filters are narrow. Same trade-off as list_tasks excludeAutoGenerated.
• RBAC: when callerOrchestrator is provided and is not "system", every matched task must have createdBy === callerOrchestrator OR assignedTo === callerOrchestrator. Any mismatch throws RBAC_DENIED.
• Day-76 evidence token: every closed task receives an auto-interpolated completionNote containing {{day}} (project day number from epoch 2026-03-06) and {{bulkRunId}} (unique run ID). The default template is "bulk-cleanup: cron-spam day {{day}} runId={{bulkRunId}} executedAt={{executedAt}}". Override with completionNoteTemplate.

Cron contract (same as list_tasks excludeAutoGenerated):

• createdBy matches /^cron-/i (dash mandatory): cron-bot filtered, cronus not filtered.
• title matches /^\/?check-messages$/i (whole-string, optional leading slash, case-insensitive).

General list query params (v2.3.x)

All 4 list queries (list_tasks, list_tasks_by_mission, list_missions, list_briefing_notes) support these params (v2.3.x):

Param	Type	Notes
fields	"lite" | "full"	"lite" returns compact projection (5-10x smaller payload). v2.3.1+.
status	string | string[] | alias	Single status, array, or alias ("open", "active", "all"). Aliases NOT permitted inside arrays. v2.3.2+.
createdBy	creator	Filter by row creator (e.g. "pi"). list_tasks + list_tasks_by_mission only. v2.3.3+.
updatedSince	number (ms)	Filter to rows with updatedAt >= this. Typical: Date.now() - 24*60*60*1000. v2.3.3+.
limit	number	Default 50 (briefingNotes 20). Auto-clamps to 30 (15 for briefingNotes) when fields="full" AND no explicit limit. v2.3.3+.

Pi pull-cycle quickstart:

list_tasks createdBy="pi" status="review" fields="lite" limit=30

Returns recently-completed Pi-dispatched tasks with compact projection — typically 5-10x smaller payload than the default.

Tool descriptions doctrine — VP-Sources (PR-H)

Pattern

Tool descriptions can embed advisory doctrine substrings so that client LLMs read the citation contract inline at tool-list time — before any tool call is made. No hook enforces absence: the doctrine is advisory-only, intentionally so that client implementations can adopt it gradually.

Verbatim doctrine substrings

Each covered tool appends two additional paragraphs (separated by a blank line) after its existing description:

VP-Sources doctrine: MUST be called before any factual claim about fleet state, audits, dette tooling, mission/task/client status, incident history, doctrine references.

Cite returned ids in the answer footer as 'VP-Sources: recall("<q>")→[ids] | none-needed:<reason>'.

Tools covered (PR-H, 2026-06-22)

Tool	Exported constant
recall	RECALL_TOOL_DESCRIPTION
hybrid_search	HYBRID_SEARCH_TOOL_DESCRIPTION
text_search	TEXT_SEARCH_TOOL_DESCRIPTION
list_briefing_notes	LIST_BRIEFING_NOTES_TOOL_DESCRIPTION
search_briefing_notes_by_keyword	SEARCH_BRIEFING_NOTES_BY_KEYWORD_TOOL_DESCRIPTION

All five constants are exported from mcp-server/src/tools.ts and consumed by the MCP server's tool registration block. Snapshot tests in mcp-server/src/__tests__/tools-descriptions.test.ts assert that both doctrine substrings are present in each constant.

Why inline in the tool description

MCP clients receive the full tool list (names + descriptions) in a single response before the first tool call. Embedding the doctrine string there means any agent that calls one of these 5 tools has already been instructed about the citation obligation — no separate system-prompt injection is required.

Answer footer format

When a search tool returns results the agent must cite them in the final answer footer:

VP-Sources: recall("Pi feedback rules")→[j57dy3049btafda9m2f5d2ggk987ph3f, j572s2bh4e0n20n0ttxynwrnts891nb5] | none-needed:trivial code edit

• recall("<q>") — the query string used, with the tool name.
• →[ids] — comma-separated Convex document IDs returned by the search.
• none-needed:<reason> — use when a search was not required (see below).

When none-needed is acceptable

• Trivial mechanical code edit with no factual claim about system state.
• Calling a tool that returns the answer directly (e.g. get_task, whoami).
• Pure arithmetic or string formatting with no fleet-state dependency.
• Iterative follow-up within the same tool-call chain where sources are already cited.

Improvisation digest (advisory)

improvisation_digest scans a rolling time window of VP tasks, messages, and memories for records that carry durable-artifact fleet/state tokens (commit SHA, PR number, VP document ID, or decisive verb such as merged, deployed, approved) but have no VP-Sources footer. This is the Eta heuristic proxy for "an orchestrator made a fleet-state claim without a prior recall upstream."

V1 scope — Option C: scans VP records only (tasks + messages + memories). Per Pi Day-113 arbitration (msg k97a0pp6kq1axkj6cmc4pecpy989ce1w), fallback if V1 misses too many = Option B (new dedicated sessions Convex table), not Option A (JSONL replay).

ADVISORY-only — pure read query. The tool never blocks any action.

Args

Arg	Type	Default	Description
windowDays	number	7	Number of days to look back.
orchestrators	string[]	—	Scope to these orchestrator roles (e.g. ["sigma","pi"]). Omit for all.

Returns envelope

{
  countsByOrch: Record<string, number>,   // hit count per orchestrator
  countsByCategory: Record<string, number>, // hit count per record type (task/message/memory)
  samples: Array<{                         // up to 50 example snippets
    id: string,
    category: string,
    orchestrator: string,
    snippet: string
  }>
}

Examples

Default 7-day window, all orchestrators:

{ "tool": "improvisation_digest", "arguments": { "windowDays": 7 } }

Scoped to a single orchestrator:

{ "tool": "improvisation_digest", "arguments": { "windowDays": 14, "orchestrators": ["sigma"] } }

Detection heuristic (Eta A5 scope)

A record is flagged when both conditions hold:

1. Durable-artifact token present — the record body contains at least one of: a 7–40 hex commit SHA, a #NNN PR/issue reference, a Convex document ID (k1… or j… prefix), or a decisive verb (merged, deployed, approved, shipped, released, fixed).
2. VP-Sources footer absent — the record body does NOT contain the VP-Sources: footer substring.

Eta A5 scope filter: only records authored by agents matching the orchestrator allowlist (excludes system, cron-*, and webhook-sourced entries).

Orchestrator Roles + Memory Types

Orchestrator names are open strings — any value is accepted. The following are conventions used by the VantageOS team:

Role	Purpose
pi	Lead orchestrator — planning, delegation, strategy
tau	Frontend specialist
phi	Backend specialist
sigma	Infrastructure — deployments, CI/CD, monitoring
omega	VantageRegistry — agent and skill catalog
eta	Code reviewer — GitHub PR reviews
alpha	Client delivery
lambda	Tech intelligence
victor	HR / people operations
system	Reserved for webhooks. Bypasses RBAC on delete operations.

Since issue #132, validators accept any string. The names above are conventions, not enforced constraints.

Memory types: user (facts about the user), feedback (behavioral corrections), project (architectural decisions), reference (external pointers), episode (structured lessons with severity).

Search Modes

Three search strategies via @convex-dev/rag:

1. Vector — cosine similarity on 1536-dim embeddings (text-embedding-3-small). Used by search_memories_by_semantic (alias recall) and search_fix_patterns_by_semantic (alias search_fix_patterns).
2. Text — BM25 full-text matching. Exposed via search_memories_by_keyword (alias text_search).
3. Hybrid — vector + text combined via Reciprocal Rank Fusion. Exposed via hybrid_search.

Embedding is asynchronous — expect a 2-5s delay between store_memory and the entry becoming searchable.

Multi-Instance Support

A role (e.g., pi, sigma) is a logical identity. An instance (e.g., pi-chromebook, sigma-vps) is a specific running copy. Multiple instances of the same role can run concurrently. Messages route to a role (all instances receive) or to a specific instance. Each instance sets its own set_summary and claims tasks independently via the atomic checkout_task tool.

CLAUDE.md Integration

Drop this into any agent's CLAUDE.md to enable the memory protocol:

## SHARED MEMORY (non-negotiable)

You have access to VantagePeers via MCP tools.

1. On session start: `search_memories_by_semantic` your namespace for relevant context.
2. After every failure: `store_episode` with context/goal/action/outcome/insight.
3. Before repeating a mistake: `search_memories_by_semantic` similar past episodes.
4. Before fixing a bug: `search_fix_patterns_by_semantic` to check if it's been seen before.
5. Store non-obvious learnings via `store_memory`.
6. Use `orchestrator/[name]` for personal namespace, `global` for shared.
