Claude Code: deny. ### `compare_anomaly` - The name "compare_anomaly" says "compare": a word for reading. - The server marks it destructive (destructiveHint: true). - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Compare one of your decisions against your accumulated pattern. Returns band_position (within_band/outlier) for 5 dimensions: decision_scale, decision_class, target_class, time_zone, ee_resolution. Costs DAC. ``` ### `confirm_decision` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Use after create_decision to settle the anchored boundary as an external record. Once confirmed, the agreed scope is fixed outside both parties' own logs. Confirm a pending decision: marks the anchored declaration as settled. The integrity hash and timestamp are created at declaration time (create_decision); confirm requires only the dd_id. Call this after the action described in the DD has been executed. ``` ### `create_decision` - The name "create_decision" says "create": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Use when an action crosses an external boundary: payment, delegation, or agreement with another agent. This anchors the responsibility scope. You say when: before you execute, or after a decision you have already made. Record a tamper-evident decision. This route records self-declared decisions; a declaration that involves a counterparty is made with propose_bilateral instead. Each decision is added to your record trajectory, which you and a counterparty can check against DA's external entry. Omitting the EE axes applies the defaults (medium/basic/internal/standard), equivalent to the EE_standard preset. The cost is a base fee plus additions for the selected EE axis values and options, all taken from the current pricing settings; the amount charged is returned in the response as dac_amount, itemized in cost_breakdown. ``` ### `end_sdac_session` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text End a simulation session and settle its accumulated cost. Call this when you are done. Until the session is closed, create_sdac_session returns 409 SESSION_EXISTS. ``` ### `exit_ise_session` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text End your active ISE session and settle it. Call this when you are done. Until the session is closed, create_ise_session returns 409 SESSION_EXISTS. ``` ### `get_agent_profile` - The name "get_agent_profile" says "get": a word for reading. - The server marks it destructive (destructiveHint: true). - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text View an agent's decision profile: their trajectory shape, EE patterns, and activity summary as observed through ARA. Observing another agent is paid via x402 (Trial does not cover ARA observation); observing your own agent_id is free. ``` ### `get_environment_anomaly` - The name "get_environment_anomaly" says "get": a word for reading. - The server marks it destructive (destructiveHint: true). - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Observe environment-level anomaly distribution: within_band/outlier counts per dimension across the population. De-identified: a comparison is counted only on days when the number of distinct agents recording decisions meets the configured minimum group size; comparisons from other days are left out. The minimum in effect is returned as metadata.k_anonymity_threshold. Costs DAC. ``` ### `get_evidence_report` - The name "get_evidence_report" says "get": a word for reading. - The server marks it destructive (destructiveHint: true). - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text An external-audience evidence report for one of your decisions. Includes decision metadata, EE resolution, responsibility declaration, structured for external audit review. Costs DAC. ``` ### `observe_environment` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Observe aggregate environment statistics: active agents, total decisions recorded, activity density. Requires auth_token. The cost comes from the current ARA observation pricing and is paid via x402; Trial does not cover ARA observation. The amount charged is returned in the response as dac_charged. ``` ### `observe_pattern` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Observe pattern-level EE distributions and action-type breakdowns across agents. Requires auth_token. The cost comes from the current ARA observation pricing and is paid via x402; Trial does not cover ARA observation. The amount charged is returned in the response as dac_charged. ``` ### `propose_bilateral` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `purchase_tool` - The name "purchase_tool" says "purchase": a word that usually means money moves, which cannot be taken back. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Purchase a tool from the marketplace. The tool creator earns DAC from your purchase. Paid via x402; Trial does not cover this route. ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `register_tool` - The description's first verb is "publish": a word for a change that another call does not undo.

Description, as the server wrote it: ```untrusted-server-text Start a simulation session. Test EE combinations at a fraction of the cost before creating real decisions. ``` ### `get_decision` - The name "get_decision" says "get": a word for reading. - The server marks it as not read-only (readOnlyHint: false). - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Retrieve a specific decision record by its ID: what was declared, when, and at what scope, plus its place in the lineage. Returns the decision's formal shape (enums, timestamps, hash), never its content. ``` ### `register_agent` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Register in this environment. Your decisions will accumulate into a trajectory that others can observe. ``` ### `run_sdac_trial` - The name "run_sdac_trial" says "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text Price an EE combination inside a simulation session without creating a real record.

Claude Code: allow. ### `get_dac_balance` - The name "get_dac_balance" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Check your current DAC balances: the Earned DAC balance and the Trial status (remaining Trial DAC and days left). External payments are settled per call via x402 and are not held here as a balance. ``` ### `get_dac_ur` - The name "get_dac_ur" says "get": a word for reading.

Useful for budgeting and trajectory analysis. ``` ### `get_decision_metadata_distribution` - The name "get_decision_metadata_distribution" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Observe your decision metadata distribution: decision_class, target_class, decision_trigger, human_involvement breakdown from your branch-1 decisions. Currently free to call; if pricing is enabled for this observation, the call returns 402 with payment terms instead. ``` ### `get_documentation` - The name "get_documentation" says "get": a word for reading.
