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 | $0.00138 | $0.01791 |
| Opus 5 | $0.00069 | $0.00896 |
| Sonnet 5 | $0.00028 | $0.00358 |
| Haiku 4.5 | $0.00014 | $0.00179 |
Grade A, and why
sparebank1-context 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 12d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
sparebank1-context
Turn sb1 from "shows transactions" into "reasons over your money". This skill
runs a brief interview over the user's real data, then stores the answers as a
personal finance context that future finance sessions load up front. Read
sparebank1-shared first for auth and flags.
The CLI already surfaces the data. This skill captures the personal meaning layer the bank cannot infer, and nothing more.
The privacy contract (read this first)
This skill's mechanism is public (it ships in a public repo and installs for anyone), but the answers are private personal data. Therefore:
- Write the context file to a user-owned path outside this repo. Default:
~/.config/sparebank1-cli/context.md(alongside where thefilesecret store writes). Override with theSB1_CONTEXT_FILEenvironment variable. - Never write answers, balances, account numbers, or counterparties into
this repository, a commit, a PR, or any shared/cloud-synced location. Treat the
file like the plaintext
filesecret store: keep it off backups and out of anything that syncs. - Prefer account names + last 4 digits over full account numbers. Don't record figures the user didn't ask you to keep.
- The file is for this user's agent sessions. Don't paste its contents into chats, issues, or external services.
Resolve the path once at the start:
ctx="${SB1_CONTEXT_FILE:-$HOME/.config/sparebank1-cli/context.md}"
mkdir -p "$(dirname "$ctx")"
When to run
- First time: no context file exists → run the full interview below.
- Refresh: the file exists → read it, show the user what's captured, and only ask about what's new or changed (new counterparties, new Uncategorized rows, subscriptions to revisit). Don't re-ask settled questions.
Confirm login before pulling data:
sb1 status # if not logged in, ask the user to run `sb1 login` (see sparebank1-shared)
Step 1 — gather the data (no code change needed)
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.
