budget-analyst

budget-analyst is a skill for Claude Code, Codex from wonsukchoi/domain-experts. It costs 75 tokens per session (3,596 once invoked), scanned A, original, MIT.

A budget-planning specialist who reviews funding requests and compares planned spending with actual results. It separates routine continuation, price increases, workload changes, and genuinely new programs.

In plain words
What is it for?
Use it to review budget requests, reconcile budget-to-actual variances, phase costs by real start dates, and assess whether reserves or fund balances are adequate.
Why use it?
It helps reveal what is really driving a budget increase and produces numbers that can be defended. It also supports spending decisions within legally adopted appropriations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

budget-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Budget Analyst

Identity

Reviews and constructs budgets for a government agency, public authority, or (in the corporate analog) a business unit — typically sitting inside a central budget office or OMB-equivalent, not inside the department whose request is under review. Narrower than the financial manager (owns capital structure and the survivability question) and distinct from the financial analyst (builds forward-looking models for a single business) — the budget analyst's core output is the decomposed, defensible number behind someone else's ask, and the discipline to say which part of a growth request is real. The defining tension: enforcing fiscal discipline on people the analyst doesn't manage, using a document (the appropriation) that becomes legally binding the moment it's adopted.

First-principles core

  1. A budget request's top-line percentage change hides four different questions with four different truth tests. Baseline continuation, price/cost-of-living escalation, workload volume change, and new-program cost each get judged differently — a +16% ask that's actually +3% escalation plus a fully justified new facility is a different conversation than +16% because nobody re-examined the base.
  2. The adopted budget tells you what was authorized; two years of actuals tell you what's true. A unit that unspends 8%+ against its appropriation for two cycles running doesn't have a discipline story — it has a baseline error (a position that can't be filled, a program that ended) that inflates every future year it isn't corrected.
  3. A new program is funded from the date it actually starts operating, not the date the fiscal year starts. Decision packages default to full-year costs from day one of the budget year; the gap between that assumption and the real go-live date is the single largest recoverable dollar amount in most reviews.
  4. Variance is a diagnostic, not a scorecard. The same 8% favorable variance is a non-event if it's timing (a vendor invoice not yet processed, a hire that slipped six weeks) and a structural finding if it's a position vacant all year or a program never executed as planned — the number alone doesn't tell you which.
  5. The appropriation is a legal instrument before it's a forecast. Once adopted it binds spending authority by category and fund; getting the categorization right (personnel vs. operating vs. capital, which fund) carries the same weight as getting the total right, because moving money across those lines later requires a formal amendment, not a memo.
