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 | $0.00284 |
| Opus 5 | $0.00000 | $0.00142 |
| Sonnet 5 | $0.00000 | $0.00057 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
value 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 10d 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.
What it actually says
CarsXE — Market Value
Get the current market value of a vehicle using the VIN provided in $ARGUMENTS.
Steps
- Parse $ARGUMENTS to extract the VIN (required).
- If no VIN is provided, ask: "Please provide a VIN to get the market value (e.g.,
/carsxe:value WBAFR7C57CC811956)." - Parse $ARGUMENTS for optional parameters:
state(US state code),mileage(numeric),condition(excellent/clean/average/rough). - Make an HTTP GET request:
AppendGET https://api.carsxe.com/v2/marketvalue?key=<CARSXE_API_KEY>&vin=<VIN>&source=claude_plugin&state=<STATE>,&mileage=<MILEAGE>, and/or&condition=<CONDITION>if provided. Replace<CARSXE_API_KEY>with the value of the environment variableCARSXE_API_KEY. - Present the results in a clear format:
- Current estimated market value
- Value range (low / average / high) if available
- Historical value trend if available
- Vehicle summary (year, make, model)
- Handle errors gracefully (invalid VIN, no data found, auth error).
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.

value is a command published in the GitHub repository carsxe/carsxe-claude-plugin (2 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 284 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 2026-08-31.

warden-cost
Dollar accounting — what does each active rule actually save, in money? Translates the token-measured verdict into dollars using a price table and the agent's own token-type mix, with a per-session net and a break-even. Read-only; spends no tokens.
convert
Use when the user attaches a bank statement PDF or asks for CSV/XLSX/QBO/Xero export of a converted statement. Do not use for spending analysis, reconciliation, or benchmark scoring — those have their own skills.
analyze
Use when the user asks to categorize spending, group by merchant or category, rank top merchants, or show monthly trends on converted statements. Do not use for first-time PDF conversion, period reconciliation, or benchmark scoring.
reconcile
Use when the user asks to check statement coverage, missing periods, balance continuity, or cross-account transfers. Do not use for converting a new PDF, spending categorization, or benchmark scoring.
pn-audit-performance-fe
Surgical frontend performance audit — Core Web Vitals, bundle size, image optimization, render-blocking resources, and page-type budgets. Standalone or chained by pn-frontend-audit.
valuation-methods
Valuation methods analysis — multiples, DCF inputs, PEG integration, valuation assumption extraction.
