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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00610 |
| Opus 5 | $0.00000 | $0.00305 |
| Sonnet 5 | $0.00000 | $0.00122 |
| Haiku 4.5 | $0.00000 | $0.00061 |
Grade A, and why
budget 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 5d 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
/budget — Cost Tracking
Usage

/budget --monthly
/budget --reset
Behavior
Tracks and reports AI model usage costs. Reads from .meowkit/telemetry/cost-log.json.
Execution Steps
Default (no flags)
- Read
.meowkit/telemetry/cost-log.json. - Show the last 10 tasks with: task name, complexity tier, model used, estimated token count, estimated cost.
- Print as a table:
🐱 Recent Cost Summary (last 10 tasks): ┌──────────────────────┬──────────┬───────────┬────────┬────────┐ │ Task │ Tier │ Model │ Tokens │ Cost │ ├──────────────────────┼──────────┼───────────┼────────┼────────┤ │ Add avatar upload │ Standard │ claude-4 │ 12.4k │ $0.18 │ │ Fix login typo │ Simple │ haiku │ 1.2k │ $0.01 │ │ Migrate auth service │ Complex │ claude-4 │ 45.8k │ $0.68 │ └──────────────────────┴──────────┴───────────┴────────┴────────┘ Total (last 10): $1.23
--monthly
- Read
.meowkit/telemetry/cost-log.json. - Aggregate entries by month.
- Print monthly totals:
🐱 Monthly Cost Summary: ┌────────────┬───────┬────────────┬──────────┐ │ Month │ Tasks │ Tokens │ Cost │ ├────────────┼───────┼────────────┼──────────┤ │ 2026-03 │ 24 │ 156.2k │ $12.45 │ │ 2026-02 │ 31 │ 203.8k │ $16.72 │ └────────────┴───────┴────────────┴──────────┘
--reset
- Confirm with human: "This will clear all cost tracking history. Type 'yes' to confirm."
- If confirmed: clear
.meowkit/telemetry/cost-log.json(reset to empty array). - If not confirmed: abort.
Output
Formatted table of cost data from .meowkit/telemetry/cost-log.json. No files are modified (except --reset).

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.

budget is a command published in the GitHub repository ngocsangyem/MeowKit (14 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 610 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 2026-08-30.
