Publish Index Head

publish_index_head

Read-onlyIdempotent

Publish Index Head: OpenChainGraph compute node (attestation_mandate). Deterministic OpenChainGraph compute node. By default (compute:"auto") inputs are computed server-side on Cloudflare Workers for gpu:false nodes with a registered kernel; compute:"browser" forces client-side execution and returns a browser delegation URL instead. gpu:true nodes always delegate to the browser. Inputs are processed transiently to compute the response and are not stored, logged, or retained. Use synthetic or anonymised inputs only. Exports an AP2 artifact with execution_hash for chain provenance. Consumes upstream artifacts from: art-646-compile-rebalance-evidence-pack, art-647-record-index-correction. Open at: https://ainumbers.co/chaingraph/art-658-publish-index-head.html FV-status (published/proven/still-trusted for this spec): /fv-status/ca4e1dca8343f788a296161f0e19712f7afb7e5eaec0431081e715a4cc34b784.json — a snapshot, not a subscription; this receipt verifies offline regardless of whether that file is ever fetched. Summary: Publishes one SPEC.md §HEAD-1 head-commit publication event for an index or benchmark's per-stream publication history, so an index administrator's published history (art-646-compile-rebalance-evidence-pack results, or art-647-record-index-correction events) becomes a sequence-numbered, signer-co...

Output schema: call describe_tool("publish_index_head").

Input Schema

Name	Required	Description
`compute`	No	Compute mode (v0.4 Compute Binding). "auto" (default) = server for gpu:false nodes with registered kernels; "server" = force server-side; "browser" = always return browser delegation URL. gpu:true nodes always delegate.
`parent_hashes`	No	execution_hash values from upstream ChainGraph AP2 artifacts to chain from (sets chain.parent_hashes in the export).
`parent_tool_ids`	No	tool_id values matching parent_hashes, in the same order.
`policy_parameters`	No	Input parameters for this tool's decision function. For gpu:false nodes with a registered kernel, these are computed server-side when compute is "auto" or "server". Required: chain_verification, head, prior_head, signature_verification. Unknown keys are refused.

A3.9/5.0

Behavior5/5

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

Goes well beyond the annotations: determinism, transient processing with no storage/logging/retention, synthetic-inputs-only constraint, server-vs-browser delegation rules including the gpu:true always-delegate case, and the emitted AP2 artifact with execution_hash. This is substantive behavioral context the readOnly/idempotent hints cannot convey.

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?

Front-loaded with a clear purpose sentence, but the body is a dense boilerplate dump: a bare HTML URL, a full FV-status JSON path, and a truncated fragment ('signer-co...') that suggests mechanical generation. Much of it earns its place; the URL/receipt path and truncation do not.

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

Completeness4/5

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

No output schema exists, but the description enumerates the returned fields (head_hash, prev_head_hash, seq, signer, signature_valid, chain_errors, etc.) and points to describe_tool for the full schema, which is adequate for a 4-param, nested-object 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 description coverage is 100%, so the baseline is 3. The description still adds value by tying parent_hashes/parent_tool_ids to the named upstream artifacts and explaining that policy_parameters are computed server-side for kernel-registered nodes when compute is auto/server.

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 and resource: 'Publishes one SPEC.md §HEAD-1 head-commit publication event for an index or benchmark's per-stream publication history.' The index/benchmark qualifier implicitly separates it from siblings like publish_fund_nav_head and publish_market_mark_head, though those siblings are never named.

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

Usage Guidelines3/5

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

It names the upstream artifacts it consumes (art-646-compile-rebalance-evidence-pack, art-647-record-index-correction) and gives compute-mode selection rules, which is real usage context. But it never says when to pick this over publish_fund_nav_head/publish_market_mark_head/publish_model_risk_head, nor any when-not conditions.

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