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 | $0.00164 | $0.01703 |
| Opus 5.5 | $0.00066 | $0.00681 |
| Sonnet 5.5 | $0.00033 | $0.00341 |
| Haiku 4.5 | $0.00016 | $0.00170 |
Grade A, and why
support-config 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 today.
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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Support config: a package carries only what its tool cannot inherit
Each tool has one support/ package of presets. A consuming package names a preset and carries
nothing a preset could hold. The canonical sources, which hold the preset lists:
support/tsconfig/README.md: archetypes, composition, what a config may set.support/jest/README.md: presets per layer, factories and their options.support/lint/README.md: presets per layer, the custom rules.support/fmt/oxfmt.config.mts: the one format config.- ADR: Shared Tooling Configuration via
support/Packages: why it is shaped this way.
Do not read support/README.md for this: it lags behind the per-tool READMEs.
What a consumer declares
| Tool | The package carries | The package never carries |
|---|---|---|
| TypeScript | tsconfig.json that extends a preset, plus types, paths, references, include / exclude / files when needed |
any other compiler option, an @support/tsconfig dependency |
| Jest | a one-line jest.config.js calling a preset factory, "@support/jest": "workspace:*" in devDependencies |
a hand-written config, a config that edits the factory's result |
| Lint | a lint script running plain oxlint src |
an oxlint config, a -c flag, an oxlint or @support/lint dependency |
| Format | a format script running plain oxfmt src, a format:check script running oxfmt src --check |
an oxfmt config, a -c flag, an oxfmt or @support/fmt dependency |
oxlint, oxfmt and the tsconfig, lint and fmt presets are devDependencies of the workspace root,
and a package script finds them there. Many existing packages still list oxlint or oxfmt: do
not copy that into a new package. @support/jest is the one preset a consumer declares, because its
presets carry code and peer dependencies, and the edge tells nx which tests a preset change affects.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

support-config is a skill published in the GitHub repository LedgerHQ/ledger-live (624 stars, last pushed yesterday), licensed MIT. It adds 164 tokens to every session and 1,703 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-10-29.
