Run DecisionGATE on a proposal

decisiongate_check

Run the named DecisionGATE five sequential gates on a proposal (Freedom without clarity is chaos) without executing a catalog product. Also runs automatically inside fraggate_call before exec. Use this when you want a gate check without executing a catalog product verb. Do not use it for executing a product op or searching the library; use fraggate_call or library_lookup instead. Write: appends an ask/refuse ledger tip (not idempotent). Empty {} still runs the five gates and stamps the ledger. Does not execute domain software. Named wrapper — same DecisionGATE kernel; not the full MASTER-33 hop list; Softwares exec stays fraggate_call. All proposal fields are optional. Missing evidence can fail a gate. accountable identity on this runtime is Aziel Eliab only. Mutation requires confirm=true (runtime gate) or dry_run=true (preview only, no write). confirm and dry_run stay optional on inputSchema.required. dry_run still returns FG-HALLUC-TOOL, FG-STUB, FG-UNKNOWN-OP, or FG-LOCAL-ONLY when a confirm call would refuse. confirm is consent, not tenant auth, and it does not upgrade shared public-demo isolation. Returns gate view, final_state, ledger_tip, and result (code FG-OK on the named module wrapper).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
valuesNoOptional values list.
confirmNoDocumented confirmation flag. Optional in inputSchema.required (connector refresh must not break). tools/call still refuses MCP-CONFIRM-REQUIRED when confirm is missing or false unless dry_run=true. confirm is consent to run the call. It is not tenant auth and it does not upgrade shared public-demo isolation.
dry_runNoOptional preview flag. When true, do not write and do not stamp a ledger tip. Allowlist, hallucination, stub, and local-only checks still run and return the same FragGate refuse code a confirm call would get. MCP-DRY-RUN is returned only when that call would have been allowed to proceed. confirm is consent, not tenant auth, and it does not upgrade shared public-demo isolation.
evidenceNoOptional evidence strings. Missing evidence can fail a gate.
statementNoOptional proposal statement to evaluate.
impact_negNoOptional negative-impact list.
impact_posNoOptional positive-impact list.
accountableNoOptional accountable party string.

TDQS

A4.8/5.0
Behavior5/5

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

The description discloses that the tool writes to the ledger ('appends an ask/refuse ledger tip (not idempotent)'), requires confirm=true for mutation, and explains dry_run behavior including returning refusal codes. It also mentions it does not execute domain software and notes the accountable identity. This goes well beyond the sparse annotations (readOnlyHint=false, idempotentHint=false) by providing operational context and side-effect details.

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?

The description is long but dense with essential information. It front-loads the core action and usage, then covers side effects and parameter nuances. While it could be split into sections, it avoids redundancy with the schema and every clause adds useful detail.

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?

The description covers the full calling context: purpose, usage, side effects, confirmation requirements, dry_run behavior, identity, and return values (gate view, final_state, ledger_tip, result). It even addresses edge cases like empty {} and optional fields. Given the output schema exists, this is comprehensive for an agent to correctly invoke the tool.

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?

Schema coverage is 100% with detailed parameter descriptions. The description adds extra meaning by noting that 'Missing evidence can fail a gate' and 'All proposal fields are optional,' which is not obvious from individual parameter descriptions. It also clarifies the confirm/dry_run semantics in context. This adds value beyond the schema.

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 clearly states the tool runs the five DecisionGATE gates on a proposal without executing a catalog product. It explicitly differentiates from siblings by saying 'Do not use it for executing a product op or searching the library; use fraggate_call or library_lookup instead.' The verb 'run' plus resource 'DecisionGATE five sequential gates' is specific.

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 provides explicit when-to-use guidance: 'Use this when you want a gate check without executing a catalog product verb.' It also gives clear exclusions and alternatives, naming fraggate_call and library_lookup. Additionally, it notes the tool runs automatically inside fraggate_call before exec, which helps an agent decide whether to call it directly.

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