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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00186 | $0.04351 |
| Opus 5.5 | $0.00074 | $0.01740 |
| Sonnet 5.5 | $0.00037 | $0.00870 |
| Haiku 4.5 | $0.00019 | $0.00435 |
Grade A, and why
healthcare-providers-verify 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 2d 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 — 404 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Healthcare Providers Verify
Validate practitioner credentials against the NPI registry and authoritative sources, powered by Nimble's web data APIs.
User request: $ARGUMENTS
Before running any commands, read references/nimble-playbook.md for Claude Code
constraints (no shell state, no &/wait, sub-agent permissions, communication style).
Instructions
Step 0: Preflight + WSA Discovery
Sibling handoff check: Before running full preflight, check if
healthcare-providers-extract or healthcare-providers-enrich ran earlier in this
session by following the Sibling Handoff pattern from references/nimble-playbook.md.
If same-day output exists, skip CLI check and profile load, and reuse WSA Layer 1/3
inventory. Only re-run Layer 2 if the verification focus changed.
Otherwise, run full preflight from references/nimble-playbook.md (5 simultaneous
Bash calls: date calc, today, CLI check, profile load, index.md load).
Also simultaneously — run WSA discovery and setup:
mkdir -p ~/.nimble/memory/{reports,healthcare-providers-verify/checkpoints}ls ~/.nimble/memory/healthcare-providers-verify/checkpoints/ 2>/dev/null- Run Layer 1 (vertical) and Layer 3 (general tools) WSA discovery from
references/wsa-reference.md. Layer 2 (session-specific) runs after Step 1 when you know the user's specialty and verification focus.
Classify discovered agents into verification categories and validate with
nimble extract:templates get per references/wsa-reference.md.
From the preflight results:
- CLI missing or API key unset ->
references/profile-and-onboarding.md, stop - Tag all
nimbleCLI calls:nimble --client-source nimble-agent-skills <subcommand>. MCP requests are attributed at the transport level — seereferences/nimble-playbook.md. - Profile exists -> note it for context. Determine mode using smart date windowing
from
references/nimble-playbook.md:- Full mode: first run OR last run > 14 days ago
- Quick refresh: last run < 14 days ago (re-verify only previously Unverified/Flagged practitioners)
- Same-day repeat: if
last_runs.healthcare-providers-verifyis today, check for existing report at~/.nimble/memory/reports/healthcare-providers-verify-*[today].md. If found, ask: "Already ran today. Run again for fresh data?"
- No profile -> that's fine. This skill doesn't require onboarding. Proceed to Step 1.
What ships with it
6 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.

healthcare-providers-verify is a skill published in the GitHub repository Nimbleway/agent-skills (61 stars, last pushed 2d ago), licensed MIT. It adds 186 tokens to every session and 4,351 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-08-30.
