A natural-language question tool for AWS Organization spending. AWS Organizations lets one account manage multiple AWS accounts, and Cost Explorer provides usage and billing data for them.

Use it to ask why AWS spending changed, which account or service drove the change, how costs are trending, and what the current-month forecast is.

It avoids manually inspecting cost data to understand changes, growing services, account trends, or forecasts. It works from a local data snapshot.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.00476
Opus 5.5	$0.00017	$0.00190
Sonnet 5.5	$0.00008	$0.00095
Haiku 4.5	$0.00004	$0.00048

Security

Grade A, and why

ask 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 1mo 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

/cost:ask — natural-language AWS cost questions

Answer questions like "why did spend jump in June?", "which app grew the most this quarter?", or "what's my biggest service across every app?" using the user's local cost data. Keep it local-first — work from the on-disk snapshot; don't ship their figures anywhere.

Get the data

Use the mesh44-cost tool's local snapshot (jpd44/mesh44-cost, typically ~/Developer/mesh44-cost/public/data.json).

If public/data.json is missing or stale (check its generatedAt), refresh it:
```
cd ~/Developer/mesh44-cost && AWS_PROFILE=mgt npm run fetch
```
Run aws sso login --profile mgt first if the SSO session is expired.
Read public/data.json. It contains:
- months, totalsByMonth, totalThisMonth, totalLastMonth, forecastThisMonth
- apps[] — per account: name, accountId, series (6-month), current, previous, topService
- topServices[] — service + amount for the current month

Answer

Compute the specifics from the JSON: deltas, % change, which account/service drove a change, trend direction, forecast vs. last month.
Cite concrete numbers — e.g. "June was $58.40, up 42% from May's $41.00, driven by daily-deutsch's load balancer ($44 of it)."
If the question needs a dimension the snapshot doesn't have (daily granularity, a specific tag, a service within one account over time), say so and offer to pull it with a targeted Cost Explorer query via the AWS CLI (aws ce get-cost-and-usage ... --profile mgt).

Privacy contract

Read-only, local-first. The data stays on the user's machine; use only the figures needed to answer.

Changes

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.
