The primary manifest — the file an agent reads to learn what this artifact does.
AgentRecall is a persistent memory system. Default surface: 5 tools (two verbs + three essentials). Full surface: 6 tools via npx agent-recall-mcp --full (adds check_action); 13 tools with AR_EXTRAS=1 npx agent-recall-mcp --full. This guide describes how and when to use them.
Two-verb model: session_start (inhale — load context) and session_end (exhale — save and compound). Everything else is available but secondary; most agents never need more than the default 5. See Automaticity Law below.
AgentRecall requires the MCP server to be running. If tool calls fail with "unknown tool", the human needs to install it first.

transport: stdioAgentRecall's default surface provides 5 tools. Start the server with --full to add check_action (6 tools); set AR_EXTRAS=1 together with --full to also enable the quarantined extras (13 tools).
Default tools (always available): session_start, session_end, remember, recall, check
Full-mode only (`--full`): check_action
Extras (`AR_EXTRAS=1 --full`, quarantined in the 2026-07-05 purity census): pipeline_open, pipeline_close, pipeline_list, pipeline_current, pipeline_show, register_rule, digest
session_startWhen: Beginning of a session, to load prior context.
What it returns:
project — detected project nameidentity — who the user is (1-2 lines)insights — top 5 awareness insights (title + confirmation count + severity)active_rooms — top 5 palace rooms by salience (with staleness flag + last_updated)_(Palace = your project's long-term knowledge store, organized into topic rooms like "architecture", "goals", "blockers". Salience = relevance score 0-1 based on recency, access frequency, and connections. Rooms with stale=true haven't been updated in 7+ days.)_
cross_project — insights from other projects matching current contextrecent — today/yesterday journal briefswatch_for — predictive warnings from past correction patterns + decision calibrationcorrections — P0 behavioral rules (max 10, always loaded, never expire)resume — structured re-entry briefing: last_date, last_trajectory, sessions_countHow to use the response:
identity to calibrate your tone and approachinsights — these are battle-tested lessons. Follow them.watch_for — these are patterns where you've been wrong before on this project. Adjust your approach.recent to understand where the last session left offExample call:
session_start({ project: "auto" })rememberWhen: You learn something worth keeping. A decision, a bug fix, an insight, a session note.
What it does: Auto-classifies your content and routes it to the right store:
You do NOT need to decide where it goes. Just describe what to remember.
How to use:
remember({
content: "We decided to use GraphQL instead of REST because the frontend needs flexible queries",
context: "architecture decision" // optional hint, improves routing
})Returns: routed_to (which store), classification (content type), auto_name (semantic slug generated)
recallWhen: You need to find something from past sessions. A decision, a pattern, a lesson.
What it does: Searches ALL stores at once using Reciprocal Rank Fusion (RRF) — each source (palace, journal, insights) ranks internally, then positions merge so no single source dominates. Journal entries decay fast via Ebbinghaus curve (S=2 days); palace entries are near-permanent (S=9999). Returns ranked results with stable IDs.
How to use:
recall({ query: "authentication design", limit: 5 })Feedback: After using results, rate them. Ratings use a Bayesian Beta model — the mathematically optimal estimate of true usefulness:
recall({
query: "auth patterns",
feedback: [
{ id: "abc123", useful: true }, // Beta(2,1) → ×1.33 next time
{ id: "def456", useful: false } // Beta(1,2) → ×0.67 next time
]
})Feedback is query-aware — rating something "useless" for one query doesn't penalize it for unrelated queries.
session_endWhen: End of session, after work is done.
What it does in one call:
How to use:
session_end({
summary: "Built auth module with JWT refresh rotation. Fixed CORS bug.",
insights: [
{
title: "JWT refresh tokens need httpOnly cookies — localStorage is vulnerable",
evidence: "XSS attack vector discovered during security review",
applies_when: ["auth", "jwt", "security", "cookies"],
severity: "critical"
}
],
trajectory: "Next: add rate limiting to API endpoints"
})Rules for insights:
applies_when keywords determine when this insight surfaces in future sessions across ALL projects.Return fields:
journal_written — boolean, true if journal entry was savedawareness_updated — boolean, true if any insight was storedpalace_consolidated — boolean, true if palace rooms were updatedinsights_processed — number of insights acceptedquality_warnings — advisory warnings if insights are too short, lack evidence, or use event-verb phrasing (never blocks saves)card — formatted save summary (box-drawing card)merge_suggestions — array of similar recent entries (optional)checkWhen: Before executing a complex task where you might misunderstand the human's intent. Also for tracking decision quality over time.
What it does:
watch_for — patterns from past corrections on this projectsimilar_past_deltas — times you misunderstood similar goals beforeTwo-call pattern (correction tracking):
Call 1 — before work:
check({
goal: "Build REST API for user management",
confidence: "medium",
assumptions: ["User wants REST, not GraphQL", "CRUD endpoints", "PostgreSQL backend"]
})Read the watch_for response. If it says "You've been corrected on API style 3 times", ASK the human before proceeding.
Call 2 — after human corrects (if they do):
check({
goal: "Build REST API for user management",
confidence: "high",
human_correction: "Actually wants GraphQL, not REST",
delta: "API style preference — assumed REST, human prefers GraphQL"
})This feeds the predictive system. Future agents on this project will get warnings.
Decision trail (Bayesian-inspired calibration):
For major decisions, track confidence and outcome to calibrate judgment over time:
check({
goal: "Use GraphQL instead of REST",
confidence: "medium",
prior: 0.7, // initial confidence (0-1)
evidence: [
{ factor: "Frontend needs flexible queries", direction: "supports", weight: 0.2 },
{ factor: "No GraphQL experience on team", direction: "weakens", weight: 0.3 }
],
posterior: 0.55, // updated confidence after evidence
outcome: "rejected" // final result: "confirmed", "rejected", "partial", or free text
})When outcome is provided, the decision trail is persisted to the palace decisions room. After 3+ closed decisions, session_start surfaces calibration warnings: "Your priors average 0.8 but outcomes average 0.5 — you're overconfident."
Returns: recorded, watch_for, similar_past_deltas, decision_id (when outcome provided), decision_trail_saved, calibration_note
npx agent-recall-mcp --full)Most agents never need these — the default 5 tools carry all compounding memory value. The 2026-07-05 purity census (owner-approved) stripped the MCP full surface tocheck_action; the former pipeline/rule/digest tools are quarantined behindAR_EXTRAS=1, and everything else moved to thearCLI.
check_actionWhen: Right before a risky or hard-to-reverse action — publish, push, deploy, delete, credential exposure, external send.
What it does: Pre-action safety matcher — checks the described action against active corrections and rules, and returns matching warnings before you act.
check_action({ action_description: "npm publish agent-recall-mcp" })AR_EXTRAS=1 npx agent-recall-mcp --full)Quarantined in the purity census for near-zero organic use; core logic is intact and the tools re-register when the env var is set:
pipeline_open / pipeline_close / pipeline_list / pipeline_current / pipeline_show — project narrative spine (phases with reflection fields)register_rule — save an IF-THEN behavior policydigest — context cache (store / recall / read / invalidate pre-computed analysis)memory_query, skill_write, skill_recall, skill_list, dashboard_export, session_end_reflect, project_board, project_status, bootstrap_scan, and bootstrap_import were removed from the MCP surface in the 2026-07-05 purity census. Their CLI paths remain intact. First-time bootstrap now runs through the CLI:
ar bootstrap # scan and show what's available
ar bootstrap --dry-run # preview what would be imported
ar bootstrap --import # import all new projects
ar bootstrap --import --project my-app # import one projectBootstrap scan is read-only (never writes to your machine or to AgentRecall); import only writes to ~/.agent-recall/, skips .env, credentials, .pem, and .key files, and never double-imports projects already in AgentRecall.
1. session_start() → load context, read insights and warnings
2. Present brief to human → "Last session: X. Insights: Y. Ready."
3. check() if task is complex → verify understanding before work4. remember() when you learn something → auto-routes to right store
(stores: journal for daily activity, palace rooms for persistent decisions, awareness for cross-project insights)
5. recall() when you need past context → searches everything
6. check() before major decisions → verify understanding7. check() with corrections if any → record what human corrected
8. session_end() → save journal + insights + consolidation
9. Done — all data saved locally (only push to git if user explicitly asks)Each layer feeds the next. The system gets better the more you use it.
SAVE: remember("JWT needs httpOnly cookies")
→ Auto-named: "lesson-jwt-httponly-cookies-security"
→ Indexed in palace + insights
→ Auto-linked to "architecture" room (keyword overlap)
→ Salience scored: recency(0.30) + access(0.25) + connections(0.20) + ...
RECALL: recall("cookie security") — 3 sessions later, different project
→ Finds the JWT insight via keyword match + graph edge traversal
→ Agent rates it useful → feedback boosts future ranking
→ Next recall on similar query → this result surfaces higher
COMPOUND: After 10 sessions
→ 200-line awareness contains cross-validated insights
→ watch_for warns about past mistakes before they repeat
→ Corrections auto-promote to awareness at 3+ occurrences
→ Graph connects related memories across rooms automaticallyremember calls during work.

All platforms use the same tools. No platform-specific behavior.
The Automaticity Law (measured on the live corpus — 44 projects, 221 journals, 81 corrections, 2026-06-12): push channels (session_start, session_end, correction hooks, ambient recall) showed repeated behavior-changing usage across weeks of real agent sessions. Pull channels — check_action, skill_recall, pipeline_*, memory_query — had zero organic calls, including from the agent that built them.
Every extra tool in the default surface burns tool-definition tokens every session for zero behavioral return. The two-verb model (inhale = session_start, exhale = session_end) carries all compounding memory value. Everything else is available via --full for agents and workflows that explicitly need it.
Corollary: wire before write — a primitive without an automatic trigger will not be used.
