A schema-defined tool provides a structured interface between Claude and the application. The tool’s input_schema can declare required properties, nested work-experience and education objects, arrays of skills, and exact data types. Claude then supplies the extracted resume information as tool-call arguments, which the application can read directly from the tool_use response.

Anthropic’s tool documentation specifies that a custom tool definition includes a JSON Schema object describing its expected parameters. Current strict tool use can additionally enforce that generated tool arguments match the declared schema exactly. This removes the need to locate JSON inside free-form text or depend on post-generation repair. ( https://docs.anthropic.com/en/docs/agents-and-tools/tool-use/implement-tool-use )

Option A is fragile because regular expressions do not provide a robust parser for arbitrary nested JSON and cannot correct missing properties or incorrect types. Option B improves formatting behavior but remains probabilistic. Option C doubles latency and creates two opportunities for information loss: first during extraction and again during reformatting.

In a production design, fields that may genuinely be absent from a resume should be optional or nullable rather than forcing invented values. The tool schema should also use strict: true where supported. Among the available choices, D provides the strongest structural guarantee and the cleanest downstream integration.

Option B removes the ambiguity from the tool interface itself. The agent no longer needs to choose between separate functions that represent closely related business operations. Instead, a single compensation tool exposes an explicit action parameter, while the existing order lookup tool can optionally return delivery-tracking information through a clearly defined flag.

Anthropic’s tool-design guidance recommends consolidating related operations into fewer, more capable tools when separate functions create unnecessary semantic overlap. Claude selects tools primarily from their names, descriptions, schemas, and the current task. When multiple tools appear capable of satisfying the same request, selection accuracy declines because the agent must infer distinctions that should have been made explicit in the interface design.

Option A adds routing complexity but leaves overlapping financial operations available within the same sub-agent. Option C reduces the number of tools loaded initially, but it does not eliminate the semantic duplication between compensation operations or overlapping lookup functions. Option D may improve behavior through examples, but it compensates for a poorly designed tool surface rather than correcting the root cause.

The consolidated schemas should use enums for supported actions, clearly define when each action applies, and document the returned fields. This creates a smaller and more deterministic agent-computer interface.

Project skills are stored at .claude/skills/ < skill-name > /SKILL.md . The directory name becomes the invocable command name, so .claude/skills/migrate-component/SKILL.md creates /migrate-component . Anthropic distinguishes project skills from personal skills: project skills apply only to the repository, while skills under ~/.claude/skills/ apply to one user across all projects. ( https://code.claude.com/docs/en/skills )

Committing the project skill to version control ensures that every developer receives the same workflow and that changes are reviewed, versioned, and synchronized with the codebase. Anthropic’s .claude directory guidance states that project configuration should be committed when it is intended to be shared with the team, whereas files under ~/.claude are personal. ( https://code.claude.com/docs/en/claude-directory )

Option A requires manual duplication across developer machines and allows versions to diverge. Option B loads the migration procedure into every conversation even when no migration is occurring; Anthropic recommends skills for reusable checklists and multi-step procedures because their bodies load only when used. Option C describes no valid mechanism for defining a skill’s content in settings.json .

Option D provides the correct scope, command name, on-demand loading behavior, and team distribution model.
