A command that shows an Octopus energy bill summary for a selected period, defaulting to the previous month. Octopus is an energy supplier, and the summary groups costs and usage by fuel.

Use it to request a period's bill summary and present the results with a grand total and any unavailable-fuel notes.

It turns billing information into a consistent table with usage, unit charges, standing charges, and totals. It also identifies fuels that could not be included.

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	$0.00014	$0.00123
Opus 5.5	$0.00006	$0.00049
Sonnet 5.5	$0.00003	$0.00025
Haiku 4.5	$0.00001	$0.00012

Measured 2mo ago against content hash 934b0fc91dde, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

bill 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 2mo 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

Use the bill_summary MCP tool with period.kind = "$1" (default last_month if $1 is empty).

Format the result as a markdown table:

Columns: Fuel | kWh | Unit £ | Standing £ | Total £
Add a final row with the grand total.
Mention any caveats from the response in a short footnote.
If fuels_unavailable is non-empty, note which fuels were skipped and why.

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.
