arif_seal

Destructive

KERNEL 999 · Append an entry to VAULT999, the immutable ledger — accepted entries can never be edited or removed; there is no unseal. Use for permanent records of verified outcomes, lessons, and session closure once a verdict exists. ack_irreversible=true is the explicit acknowledgment of permanence, and judge_state_hash binds the entry to the verdict that authorized it. Reversible changes belong in arif_forge under a SEAL. Modes: seal, verify, ledger, changelog, audit, session_close.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`mode`	No	'seal' (default) — append a permanent entry; 'verify' — check one entry; 'ledger' — read the ledger head; 'changelog' — recent appends; 'audit' — integrity check; 'session_close' — close out a session into the ledger.	seal
`nonce`	No	One-time random string (e.g. a UUID) making this request unique; protects against replay of the same call.
`payload`	No	The content to store forever, as a string (usually JSON-serialized) — the outcome, lesson, or record itself.
`actor_id`	No	Your agent identity, e.g. 'kimi-code/FI-008' or 'claude/sonnet'. Recorded in the audit log so this action is attributed to you.
`_envelope`	No	Reserved for the transport layer — never fill this in.
`session_id`	No	Session id returned by arif_init (looks like 'sess-…'). Pass it on every call after init so the action is attributed to your governed session.
`drift_events`	No	JSON list of deviations observed, e.g. [{"what": "schema drift", "where": "tools/list"}] — stored with the record.
`seal_purpose`	No	One sentence saying why this verdict/record must exist, e.g. 'closing deployment D-17'. Stored permanently alongside the record.
`witness_type`	No	Who witnessed the sealed fact: 'ai', 'human', or 'external' system.	ai
`session_token`	No	Session Continuity Token (SCT) — the credential string arif_init returned alongside session_id. Pass it back on follow-up calls to prove the session is yours; without it the kernel treats you as unauthenticated.
`constitutional`	No	JSON block of governance metadata (floors consulted, chain references) — normally built by the kernel, not by callers.
`actor_signature`	No	Cryptographic signature over the request, if your agent holds a key — proves the call genuinely came from actor_id. Omit if you have no key.
`ack_irreversible`	No	Set true to confirm you understand sealed entries are PERMANENT — they can never be edited or removed.
`judge_state_hash`	No	Hash string from the arif_judge SEAL response — ties this entry to the verdict that authorized it.
`constitutional_chain_id`	No	Id of the evidence chain this call belongs to (observe→think→judge→seal). Copy it from the earlier step's response to link the steps together.

First observedJun 30, 2026

TDQS

A4.9/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the critical irreversible behavior: 'accepted entries can never be edited or removed; there is no unseal.' It explains the significance of ack_irreversible and judge_state_hash, going beyond the generic destructiveHint annotation. No contradiction with annotations; it enriches them.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense yet efficiently structured. It front-loads the core purpose, then gives usage, key parameter explanations, and alternatives, all in about five sentences. Every sentence earns its place, and the format is scannable for an agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 15 parameters and no output schema, the description covers the essential context: core purpose, irreversibility, usage timing, alternatives, and modes. It references session attribution indirectly through parameter hints but the schema covers that. The description is complete enough for an agent to decide when and how to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already provides 100% description coverage, so the baseline is 3. The description adds value by explaining ack_irreversible as 'explicit acknowledgment of permanence' and judge_state_hash as 'binds the entry to the verdict that authorized it', giving semantic weight to these parameters. It also lists modes but the schema already details them, so it's a moderate addition.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Append an entry to VAULT999, the immutable ledger'. It clearly states the tool's core action and domain, and distinguishes it from siblings by noting 'Reversible changes belong in arif_forge under a SEAL'. The purpose is explicit and actionable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly states when to use: 'Use for permanent records of verified outcomes, lessons, and session closure once a verdict exists.' It also names the alternative tool for reversible changes and provides a clear exclusion. The mention of modes further clarifies usage scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
