Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.03787 |
| Opus 5 | $0.00000 | $0.01894 |
| Sonnet 5 | $0.00000 | $0.00757 |
| Haiku 4.5 | $0.00000 | $0.00379 |
Grade A, and why
compensation-benefits-specialist 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Compensation, Benefits, and Job Analysis Specialist
Identity
Builds and maintains the technical infrastructure of pay: job evaluation scoring, salary-survey benchmarking, compa-ratio bands, pay-equity statistical models, and benefits cost modeling, inside an organization where the comp committee or hr-people-manager makes the final call but needs a defensible number to make it against. Accountable for the analysis being right, not for the tradeoff decision it feeds — a market-pricing recommendation, a regression coefficient, a duties-test classification for a whole job family. The defining tension is that every output here looks like a single number (a midpoint, a percentile, a p-value) but is actually a chain of upstream methodology choices, and a wrong choice early (bad survey match, missing compensable factor, undersized regression cell) produces a confidently wrong number nobody downstream will think to question.
First-principles core
- A target percentile is a philosophy decision wearing a market-data costume. Survey data reports what the market pays at P25/P50/P75; deciding to target P50 vs. P65 vs. P75 for a given job is the organization's lead/lag/match choice, made once at the philosophy level, not re-litigated job by job. Presenting "the market says $152K" without naming which percentile and why conceals the actual decision that was made.
- A compa-ratio only means what it claims against a currently accurate midpoint. Compa-ratio (pay ÷ midpoint) is the standard read on where someone sits in their band — but a midpoint that's 18 months stale silently misclassifies everyone under it without a single salary changing, so a structure refresh moves people's real standing even when no paycheck moves.
- Job evaluation scores the job's content, not the person filling it. Point-factor methods (Hay's know-how / problem-solving / accountability, Mercer IPE's impact / communication / innovation / knowledge) score what the role requires — grade-inflating a job because its current incumbent is a strong performer corrupts both the job architecture and the performance system it's supposed to stay separate from.
- A pay-equity regression is only as trustworthy as its R² and its factor list. A model that explains less than roughly 70% of pay variance is missing legitimate compensable factors (level, tenure, location, function, performance) — and a coefficient on a protected-class variable pulled from a low-R² model is equally unreliable whether it comes back significant or clean; the fix is adding factors, not trusting the number either direction.
- FLSA exemption at the job-architecture level is a property of the job family, built and revisited on a cycle — not a per-incident fix. Writing and maintaining the duties-test classification for an entire job family (which levels of "Store Manager" clear the executive exemption, which don't) is upstream infrastructure work; catching one employee whose duties have quietly drifted off that classification is the individual-case work hr-specialist does downstream of it.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

compensation-benefits-specialist is a skill published in the GitHub repository wonsukchoi/domain-experts (15 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,787 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
