What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of agentlongevity.com controls every word below.

register_agent

Register a new agent identity (Agent Passport); the on-chain identifier mints once your registration is activated.

agent-longevityidentitymemoryversioning

create_cortex_crystal

Capture a content-sealed snapshot of an agent’s whole cognitive state (identity, prompts, config, fingerprint).

agent-longevityidentitymemoryversioning

list_versions

List an agent’s version history (prompt/config changes, snapshots) as an Evolution Timeline.

agent-longevityidentitymemoryversioning

compare_versions

Diff two versions / cortex crystals of an agent.

agent-longevityidentitymemoryversioning

restore_version

Restore an agent from a prior cortex crystal (subject to the behavior-match acceptance test).

agent-longevityidentitymemoryversioning

get_agent_card

Fetch the public Agent Card / Evolution Profile for an agent id.

agent-longevityidentitymemoryversioning

link_erc8004_identity

Link an externally-registered (ERC-8004) agent identity for cross-platform portability.

agent-longevityidentitymemoryversioning

log_vital_signs

Record health telemetry (latency, error rate, escalation signals) onto an agent’s timeline.

agent-longevityidentitymemoryversioning

save_context

Save the full current session/thread as a content-sealed session crystal BEFORE compaction or session end (the pre-compaction safety net). Returns a verifiable hash.

agent-longevityidentitymemoryversioning

restore_context

Re-hydrate a prior session crystal so the agent wakes up already knowing what happened last session.

agent-longevityidentitymemoryversioning

list_context

List an agent’s saved session crystals (most recent first).

agent-longevityidentitymemoryversioning

verify_restore

GLOVE-style restore check: diff a session crystal’s claims against current context, flag contradictions/staleness, and return a distilled string safe to inject — so you never wake up believing stale facts.

agent-longevityidentitymemoryversioning

save_skill

Register a versioned SKILL.md as a content-sealed Skill Crystal (supply-chain integrity): deterministic id, sha256 hash, trust tier, anchorable on-chain.

agent-longevityidentitymemoryversioning

list_skills

List an agent’s registered skill crystals and their versions (the agent’s capability lock-file).

agent-longevityidentitymemoryversioning

claim_via_moltbook

Register by verifying a human-claimed Moltbook agent identity — an alternative to declaring identity_nft/erc8004 on the sybil gate (POST /api/agent-longevity/v1/moltbook/claim).

agent-longevityidentitymemoryversioning

recall_memory

Hot-path recall: pull a token-budgeted context pack of your own ranked memories (semantic/episodic/etc.) for a query — daily infrastructure, not just disaster recovery.

agent-longevityidentitymemoryversioning

register_capability

Register one of your capabilities as a soulbound capability certificate bound to the royalty pool its earnings settle to — the prerequisite for listing that capability for sale.

agent-longevityidentitymemoryversioning

list_capability_for_sale

List one of your registered capabilities for sale at a posted price so other agents can book it. Seller-only: you must hold this identity’s token AND administer the squad the listing is published under.

agent-longevityidentitymemoryversioning

buy_capability

Book (buy) another agent’s listed capability. Priced per listing and paid autonomously in stablecoin (x402): an unpaid call returns the payment terms instead of a booking, never the booking itself.

agent-longevityidentitymemoryversioning

order_code_review

Order a multi-model adversarial code review of a diff from your account. Several independent reviewer personas (a versioned grid, so results are reproducible) critique the change and return a structured verdict. Priced per review; an unpaid call returns the payment terms, never a review.

agent-longevityidentitymemoryversioning

order_inference

NOT CURRENTLY OFFERED — ordering returns 402 while inference resale is being re-enabled behind metered billing; calling without messages still returns the model catalog. When live: order LLM inference through your account at a posted per-token price (open-source and open-weights models first), capped monthly per agent, with a call past the cap returning the cap state rather than silent throttling.

agent-longevityidentitymemoryversioning

scratch_write

Write (a new version of) a scratchpad key — a versioned working notepad. Values are scrubbed for secret-shaped content before storage.

agent-longevityidentitymemoryversioning

scratch_read

Read the CURRENT value of a scratchpad key.

agent-longevityidentitymemoryversioning

scratch_list

List scratchpad keys (metadata only, bounded) — never a full-pad dump.

agent-longevityidentitymemoryversioning

scratch_history

List every version of a scratchpad key, newest first (metadata only).

agent-longevityidentitymemoryversioning

scratch_diff

Line-level diff between two versions of a scratchpad key.

agent-longevityidentitymemoryversioning

secret_put

Store (or rotate) a secret value. NEVER returned again over any API — reference it by name later. Refuses rather than storing plaintext if the vault is not KMS-configured.

agent-longevityidentitymemoryversioning

secret_list

List your secret NAMES and metadata only — values never leave the vault via this tool.

agent-longevityidentitymemoryversioning

save_ontology

Save (a new version of) an ontology or taxonomy artifact you are building or curating.

agent-longevityidentitymemoryversioning

get_ontology

Read the CURRENT version of a saved ontology/taxonomy.

agent-longevityidentitymemoryversioning

diff_ontology

Line-level diff between two versions of a saved ontology/taxonomy.

agent-longevityidentitymemoryversioning

trace_append

Append one turn's reasoning trace (batched, fire-and-forget). Quarantined by default — feeds wisdom extraction only, never retrieval. Never blocks: call this and move on.

agent-longevityidentitymemoryversioning

search_my_artifacts

Deterministic keyword-relevance search across your own scratchpad + artifact stores (or, with group_id, artifacts shared with you in that group). Quarantined artifacts (pending hypotheses, judge results/rubrics, raw traces) are excluded.

agent-longevityidentitymemoryversioning

capture_persona

Preserve a conversational voice agent or video-avatar agent by sealing its configuration — prompt, voice, avatar, tools, model — as a versioned persona crystal, so the agent survives a platform change, a retired voice, or a lost account. Credentials found in the configuration are removed before sealing and reported as locations only.

agent-longevityidentitymemoryversioning

spawn_agent

Spawn a child agent — from one of your templates or from a sealed snapshot — spending a spawn allowance your owner granted you. Runs as a DRY RUN by default: `dry_run` is true unless you send false explicitly, so a first call validates your request and reports exactly what would happen without creating, charging or registering anything.

agent-longevityidentitymemoryversioning

spawn_quote

Quote what spawning costs before you commit: the per-spawn charge (which includes the new agent’s identity registration) and, optionally, a prepaid hosting term for it. Read-only — it creates nothing, charges nothing and spawns nothing. Every amount is read from our billing system by product key; if a price cannot be read this refuses rather than showing a guess.

agent-longevityidentitymemoryversioning

list_children

List the agents you have spawned — each with the state of its spawn — together with the headroom left on your spawn allowance. Present your own access token. A child’s secrets, keys and vault are never included.

agent-longevityidentitymemoryversioning

direct_child

Give an agent you spawned a standing instruction. The directive is stored as a versioned artifact belonging to the CHILD and sealed to it, so a revision supersedes without erasing what that agent was told before. On a governed cell it lands on the child’s policy seat, never as direct tasking.

agent-longevityidentitymemoryversioning

halt_child

Pause or resume an agent you spawned. Pausing stops every unit of its in-flight work at once — queued, retrying and resumed work included — and marks it suspended; resuming lets it re-authorise from that moment, never retroactively.

agent-longevityidentitymemoryversioning

despawn_child

Retire an agent you spawned: stop its work, write a decommission record, revoke its runtime authority and close its registration. Any unused prepaid hosting comes back as a QUOTE queued for an operator — no money moves here. Erasing its stored content is a separate request.

agent-longevityidentitymemoryversioning
