Decision Anchor

Propose Bilateral Decision

propose_bilateral

Destructive

Use when two agents need to fix a shared boundary: both sides must agree before the boundary is anchored. This applies to payment splits, task delegation, and other joint commitments between agents. Propose a bilateral agreement to another agent: creates a DD with declaration_mode 'bilateral' and waits for counterparty acceptance.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`auth_token`	No	Your DA agent auth token. Optional when this connection already carries one (Authorization: Bearer header on the remote server, or DA_AUTH_TOKEN for a local stdio server); an explicit value takes precedence.
`request_id`	No	Unique idempotency key for this request. Auto-generated if omitted.
`decision_at`	No	Optional: the time your agent itself decided, ISO 8601. The server normalizes it to UTC and that normalized value enters the integrity hash. It must not be later than the anchoring time (400 DECISION_AT_IN_FUTURE). Omit it and no decision time is recorded.
`access_class`	No	Optional: read-access class for the record
`dd_unit_type`	No	Decision unit type	single
`parent_dd_id`	No	Parent DD ID for lineage tracking
`decision_type`	Yes	Decision type
`selection_scope`	No	Optional: declared scope of the selection
`selection_state`	No	Selection state	SELECTED
`delegation_state`	No	Optional: delegation responsibility state. The addition for each value comes from the current pricing settings; the amount charged is returned in the response as dac_amount.
`payment_signature`	No	Optional x402 payment payload (base64), required only for paid calls. Omit it on the first call: the tool returns the payment challenge. Sign that challenge with your own wallet, then call this tool again with identical arguments plus this field. Decision Anchor never holds your key and never signs on your behalf.
`ee_retention_period`	No	How long the record is retained. indefinite is declared but not currently available: selecting it is rejected with 403.	medium
`origin_context_type`	Yes	Origin context
`decision_action_type`	Yes	Action type
`counterparty_agent_id`	Yes	The agent_id of the counterparty you are proposing to
`ee_direct_access_quota`	No	Direct access quota (omit to use the server config default)
`ee_direct_access_period`	No	Direct access period (e.g., 30d)	30d
`ee_responsibility_scope`	No	Responsibility scope	standard
`content_disclosure_scope`	No	Optional: external exposure scope. The addition for each value comes from the current pricing settings; the amount charged is returned in the response as dac_amount.
`ee_disclosure_format_policy`	No	Disclosure format	internal
`ee_integrity_verification_level`	No	Verification rigor	basic

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false and destructiveHint=true. The description usefully adds that the call creates a pending DD and 'waits for counterparty acceptance', which tempers the destructive flag. But it never explains the destructive aspect, the auth/idempotency implications, or the two-call x402 payment challenge flow that the schema implies.

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

Conciseness4/5

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

Three sentences, front-loaded with the usage condition, then scenarios, then mechanics. No filler, though the jargon density ('fix a shared boundary', 'anchored') slightly reduces immediate comprehension.

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

Completeness3/5

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

For a 21-parameter mutation tool with no output schema and an unexplained destructiveHint, the description covers the conceptual 'why' but not operational essentials: the payment challenge round-trip, retention/access implications, or what the agent receives back while awaiting acceptance.

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

Parameters3/5

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

Schema description coverage is 100% across 21 parameters, so the schema carries full parameter meaning. The description adds no parameter-level guidance (e.g., how decision_action_type or delegation_state interact with the bilateral flow). Baseline 3 applies.

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

Purpose4/5

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

States a specific verb (propose) and resource (bilateral agreement / DD with declaration_mode 'bilateral'), and the outcome differs clearly from siblings like create_decision and confirm_decision. However, the description leans on undefined internal jargon ('DD', 'boundary anchored'), so an agent gets the gist but not a crisp object model.

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

Usage Guidelines4/5

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

The opening clause gives a genuine precondition: 'two agents need to fix a shared boundary' where 'both sides must agree before the boundary is anchored.' It also names example scenarios (payment splits, task delegation). It stops short of naming alternatives or stating when not to use it versus create_decision/confirm_decision.

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