Register a local hash receipt

mesh_broadcast

Record the SHA-256 hash of a local file as a verifiable receipt; does not upload, publish, or send file bytes.

Instructions

Register the SHA-256 of a local file as a hash receipt — never a publish or upload path. Use this when the operator already holds a local file and wants only its hash recorded. Do not use it for uploading bytes, publishing video, sending mail, or joining a mesh node; use local qnm-node/ anon-broadcast (local sibling, not a loopback fence of the mesh), AZMail via fraggate_call, or mesh_join instead. Write: stores a hash receipt only. Does NOT accept video bytes. Operator keeps the file. Malformed sha256 refuses MESH-BAD-INPUT; publish-shaped keys refuse MESH-NO-PUBLISH. sha256 is required (64 hex). title and product are optional labels, not file contents. 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 hash receipt (sha256, optional title).

Input Schema

TableJSON Schema

Name	Required	Description
`title`	No	Optional short title for the receipt. Not the file contents.
`sha256`	Yes	Required 64-character hex SHA-256 of the local file. Hash receipt only — not a publish path.
`confirm`	No	Documented 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_run`	No	Optional 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.
`product`	No	Optional catalog product slug to attribute the receipt. Not required.

Output Schema

TableJSON Schema

Name	Required	Description
`code`	No	FragGate or fabric code when present: FG-OK, FG-HALLUC-TOOL, FG-STUB, FG-LOCAL-ONLY, FG-UNKNOWN-OP, FG-GATE-REFUSE, FG-LAMB-REFUSE, or a module refuse such as MESH-* / AKM-*.
`door`	No	Door name. The public door is fraggate.
`ran_in`	No	Execution locale (for example aziel-runtime) when present.
`result`	No	FragGate body: ok, code, door, slug, op, engine_digest, ran_in, provenance, refusal, limitations, receipt, plus the engine result. Unknown names refuse FG-HALLUC-TOOL; stubs refuse FG-STUB.
`status`	No	HTTP-like status when present on wrappers (200 ok; 400+ error / refuse).
`display`	No	Human-facing envelope. Show display.action, title, and summary, then take the next input. Never echo raw tool names.
`receipt`	No	Optional receipt, ledger tip, or TemporalLock/ForgeReceipts exit when the door stamped one.
`refusal`	No	Explicit refuse object, code, or message when the door or engine refused.
`engine_op`	No	Resolved engine op when present (often inside result).
`ledger_tip`	No	Ask/refuse ledger tip when the door stamped one.
`provenance`	No	Provenance / input packet when the pipeline attached one.
`session_id`	No	Raw session id when session plumbing was used. Hidden unless the user asked for the chain.
`engine_slug`	No	Resolved engine slug when present (often inside result).
`limitations`	No	Capability limitations or Remain-OFF notes when present.
`engine_digest`	No	64-hex engine_digest when a true in-process engine ran (often inside result).

TDQS

A4.4/5.0

Behavior5/5

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

Annotations cover only the safety profile (readOnlyHint false, destructiveHint false, openWorldHint false), and the description goes well beyond them: it discloses refusal codes (MESH-BAD-INPUT, MESH-NO-PUBLISH, MCP-CONFIRM-REQUIRED), the confirm/dry_run mutation gate, the fact that dry_run still runs allowlist/stub/hallucination checks, and that confirm is consent rather than tenant auth. That is rich behavioral context that an agent cannot get from the annotations alone.

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

Conciseness3/5

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

The description is front-loaded and every section carries information, but it is dense and repetitive: 'confirm is consent, not tenant auth, and it does not upgrade shared public-demo isolation' appears in the description and again in both confirm and dry_run schema descriptions. The parenthetical asides ('local sibling, not a loopback fence of the mesh') add cognitive load without adding selection value.

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 write tool with a rich output schema already present, the description supplies everything an agent needs: scope, exclusions, gate requirements, refusal codes, and a brief return summary. Nothing material is missing.

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%, so the baseline is 3; the description nonetheless adds value by explaining the runtime semantics of confirm and dry_run (gate behavior, error codes returned) and by clarifying that title/product are labels rather than file contents. It stops short of 5 because the sha256 format detail (64 hex) merely restates the schema pattern.

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?

The description states a specific verb and resource ('Register the SHA-256 of a local file as a hash receipt') and explicitly distinguishes itself from publish/upload paths and from the mesh_join sibling. The only drag is the misleading tool name 'mesh_broadcast', which implies broadcasting to a mesh; the description must work to counteract that, so the purpose is clear but not effortless to extract.

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 gives an explicit positive condition ('when the operator already holds a local file and wants only its hash recorded') and enumerates the wrong-tool cases (uploading bytes, publishing video, sending mail, joining a mesh node) with named alternatives (local broadcast, AZMail via fraggate_call, mesh_join). This is exactly the when/when-not/alternatives structure that earns a 5.

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