start_workflow_improvement_delivery

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose meaningful operational traits: it accepts only staging/disposable environments, it 'issues a codx/branch', and it explicitly does not perform production deployment. However, the side effects remain opaque — what happens to the packet (is it marked delivered?), what 'issues a codx/branch' means concretely, and whether the operation is reversible or requires special authorization are all left unstated. Meaningful disclosures, but incomplete given zero annotation coverage.

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

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

Two sentences with zero filler. The first sentence front-loads the core action, and the second adds the critical environment constraint and the non-production exclusion. Every clause earns its place, and the format is scannable for an agent scanning tool definitions.

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

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

For a mutating delivery tool with 4 parameters and no annotations, the description covers the central purpose and the most important constraint (staging-only, no production), and output schema covers return values. But it leaves substantial gaps: the meaning of base_branch and repositiry_ref, the delivery pipeline context (which prior sibling produces the approved packet, and that get_workflow_improvement_delivery is the follow-up), and what 'isolated draft-PR delivery' entails operationally. Adequate for basic invocation, insufficient for confident autonomous use.

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

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

Schema description coverage is 0%, so the description must compensate for the 4 undocumented parameters. It does provide mapping for two of them: 'implementation-approved packet' corresponds to packet_id, and 'staging/disposable environments' constrains environment. However, base_branch (default 'main') and repositiry_ref (default '') receive no explanation at all, leaving the agent to guess their roles. Partial compensation for a coverage gap — better than nothing, but not sufficient for a low-coverage schema.

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

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

The description uses a specific verb+resource structure: 'Admit an implementation-approved packet to isolated draft-PR delivery.' This clearly identifies the tool as the entry point for starting delivery of an approved workflow-improvement packet, which distinguishes it from siblings like decide_workflow_improvement_packet, get_workflow_improvement_delivery, and record_workflow_improvement_delivery_event. The wording is jargon-heavy ('codex/branch'), but the core action is unambiguous. It doesn't explicitly name sibling alternatives, which keeps it from a 5.

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

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

The description provides a clear usage constraint: 'The server accepts only staging/disposable environments' and a clear exclusion: 'Production deployment is not performed by this tool.' This tells an agent when this tool is appropriate (non-production, disposable environments) and when it is not (production). The phrase 'implementation-approved packet' implies the prerequisite that a packet must have passed the approval stage before this tool is invoked. It stops short of naming alternatives explicitly, but the when/when-not context is strong.

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