UK inflation, take-home pay and public spending calculators with sources and shareable results.
Scored across 3 tools
Each tool targets a clearly distinct task: inflation adjustment, take-home pay calculation, and public spending comparison. There is no overlap in purpose or output, and descriptions reinforce their distinct domains.
All names use snake_case with a consistent verb-first pattern (adjust_for_inflation, calculate_take_home, compare_public_spending). The style is uniform and predictable.
Three tools is slightly on the low end but still within a reasonable range for a focused UK economic utility server. Each tool is substantial and earns its place, though the set feels minimal.
The tools cover inflation, income tax, and public spending comparisons, which are core UK financial queries. However, other common operations (e.g., currency conversion, loan calculations) are absent, leaving minor gaps.
Compare GBP purchasing power between years, with prices, wages and housing context. RPI covers 1948 onwards; CPI covers 1988 onwards. "now" means the latest stored observation, not a live price.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish read-only, idempotent, non-destructive, closed-world behavior. The description adds real behavioral context beyond them by defining that "now" is the latest stored observation rather than a live price, plus the historical coverage bounds of each series.
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?
Three short sentences, front-loaded with the core purpose, followed by the two constraints an agent most needs. No filler or redundancy.
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?
An output schema exists, so return values need not be explained. The description covers the tricky edge cases (series history bounds, "now" semantics), leaving only minor gaps such as rounding/precision behavior that the schema already handles.
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 coverage is 100%, so the baseline is 3, but the description adds meaning the schema does not: the historical start dates constraining which years are valid per series and the precise semantics of the "now" enum value. This exceeds baseline without fully re-documenting every parameter.
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?
States a specific verb and resource (compare GBP purchasing power between years) and clarifies the metric basis (RPI/CPI). It does not explicitly distinguish itself from the siblings calculate_take_home and compare_public_spending, so it lands just short of full sibling differentiation.
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 series coverage note (RPI from 1948, CPI from 1988) implicitly guides which measure to pick for a given year range, which is genuine implied usage. But there is no explicit when-to-use/when-not guidance and no routing versus the sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Employee income tax and National Insurance for 2026/27, or the gross salary needed for a target net income. England, Wales and Northern Ireland only; Scotland is unsupported. Excludes pensions, student loans, benefits and other income. Includes a historical UK taxpayer income rank.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds meaningful context beyond that: the tax year, the explicit Scottish exclusion, and the modelling limitations (pensions, student loans, benefits excluded) that determine whether the output is trustworthy. It does not discuss rounding or precision of the result.
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?
Three tightly packed sentences: what it computes, where it applies, what it omits. Front-loaded with the core purpose and no filler.
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?
With an output schema present, return details need not be explained, and the description still flags the extra historical income rank. Between the description's scope/limitation statements and the schema's parameter constraints, an agent has everything needed to invoke this correctly.
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 coverage is 67%, and the description largely restates what the schema's amount field already says about gross-vs-target interpretation in each mode. It reinforces the region restriction but adds no new syntax or format detail, so baseline 3 is appropriate.
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?
States a specific verb+resource (employee income tax and National Insurance for 2026/27) and covers both directions of calculation: gross-to-net and net-to-gross target. Scope is nailed down by jurisdiction (England, Wales, Northern Ireland) and by what is excluded, so an agent can distinguish it from the sibling fiscal tools without opening the schema.
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 tells the agent clearly when this applies (UK tax year 2026/27, non-Scottish jurisdictions) and what it will not account for (pensions, student loans, benefits, other income), which is effectively when-not-to-trust the result. It does not name or route to any alternative tool, so it falls short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Express a GBP amount as a share and duration of a stored 2025-26 public budget, with comparisons against other budgets. The NHS comparison uses England's DHSC day-to-day budget as a proxy. These are illustrative averages, not live spending rates.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed world). The description adds real behavioral context beyond them: the NHS comparison is a DHSC day-to-day proxy, and the figures are 'illustrative averages, not live spending rates' — an important caveat that prevents the agent from presenting output as current data.
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?
Three short sentences, purpose front-loaded, with the proxy caveat and the illustrative-averages warning each earning their place by preventing misinterpretation of the output.
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?
An output schema exists, so return structure need not be described. The description covers what the tool computes, the NHS proxy semantics, and the static/illustrative nature of the data. Only explicit routing versus the sibling tools is missing.
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 coverage is 100%, so the baseline is 3, but the description adds meaning beyond the schema: it explains what the 'nhs' enum value actually represents (England's DHSC day-to-day budget used as a proxy) and that budgets are a stored 2025-26 set, clarifying the default rather than just repeating it.
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?
States a specific verb and resource: 'Express a GBP amount as a share and duration of a stored 2025-26 public budget, with comparisons against other budgets.' This is clearly distinct from the sibling adjust_for_inflation and calculate_take_home tools, which perform conversions rather than budget comparisons.
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?
Usage is implied by the description ('comparisons against other budgets'), but there is no explicit when-to-use/when-not-to-use guidance and no reference to the sibling tools. An agent must infer that this is for illustrative budget-comparison framing rather than live or precise spending figures.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
