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 | $0.20500 | $0.20500 |
| Opus 5 | $0.10250 | $0.10250 |
| Sonnet 5 | $0.04100 | $0.04100 |
| Haiku 4.5 | $0.02050 | $0.02050 |
Grade A, and why
mise-en-space CLAUDE.md 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.
How it starts
The opening of the file, as written. The whole thing — 403 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
mise-en-space — Google Workspace MCP (Drive, Gmail) with mise-en-place philosophy: everything prepped, in its place, ready for Claude to cook with.
Versioning & releasing (suite-managed)
mise ships as part of the Batterie de Savoir suite, which carries one suite-wide version. So:
- Do NOT hand-bump
.claude-plugin/plugin.jsonto release. This repo's ownplugin.jsonversion is local-dev-only — the assembler stamps every published plugin to the suite version, overwriting it. - Release via
/batterie:publishfrom this working tree — it bumps the suite version centrally and ships the change (a 2-repo push: this repo + the central suite bump). Never hand-run the assemble. - mise is vendored full-source (it's the MCP plugin) — so any source edit here, plus
CLAUDE.md/instructions.md/skills//hooks//scripts/, is vendored content that must ride a suite bump (a publish) to ship, or the assembler quarantines the plugin.docs//.bon//tests/edits are free (excluded from the vendor) — that free list is exhaustive, so read anything absent from it as shipped.scripts/is named explicitly because it reads like local tooling and is not: the shipped plugin carries it, which is how acapture_fixtures.pythat had been broken since March 2026 went on being distributed to every user for four and a half months (mise-sowepo).

Identity flavours (mise vs mise-home) — distinct from build flavours
Mise ships as two identity flavours from this one source: mise (work — mit-workspace-mcp-server OAuth client, @itv.com) and mise-home (personal/family — planetmodha-workspace-mcp client, @planetmodha.com). This is a different axis from the full/slim build flavours (see Development → Build flavours). The home flavour is produced by spm1001/batterie/transforms/make-mise-flavour.sh, a guarded substitution transform that rewrites the identity strings in the vendored copy:
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.
