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 | $0.01661 | $0.01661 |
| Opus 5 | $0.00830 | $0.00830 |
| Sonnet 5 | $0.00332 | $0.00332 |
| Haiku 4.5 | $0.00166 | $0.00166 |
Grade A, and why
bauplan-skills 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 9d 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bauplan
Git Workflow (code repo)
This section is about git branches for source code, not Bauplan data branches.
- Always create a new git branch before making any changes. Use a descriptive branch name based on the task (e.g.,
fix/login-bug,feat/add-search). - All work happens on feature branches. The
mainbranch is off-limits for direct edits. - Commit every change immediately after making it. Each commit should have a clear, one-line message describing what changed.
- Keep commits small and focused. One logical change per commit.
- When the task is complete, leave the branch ready for review. Do not merge into
main.
Bauplan Workflow (data lakehouse)
Bauplan is a data lakehouse platform where data changes follow a Git-like workflow, but on Bauplan data branches (managed by bauplan branch), not git branches. A typical workflow looks like this:
- Create and switch to a new data branch:
bauplan checkout -b <branch> --from-ref main - Iterate on your pipeline code and test with
bauplan run --dry-run - When ready, run
bauplan runto materialize — the code is snapshotted by Bauplan and saved under the jobId the platform returns - Review changes with
bauplan branch diff main - Merge into
mainto publish
Hard safety rules (always)
- Never publish by writing directly on
main. Use a Bauplan branch and merge to publish. - Never import data directly into
main. - Before merging into
main, runbauplan branch diff mainand review changes, or usebauplan queryover the two branches to quickly compare how data changes in the target tables. - Prefer
bauplan run --dry-runduring iteration because it is much faster and safer. However, tables will not be materialized in the lake during a dry run, so the only way to preview table content is to use--preview(e.g.,bauplan run --dry-run --preview head). Materialization is blocked onmain. Every branch is readable, but only branches prefixed with your username (username.branchname) are writable by you. - When handling external API keys (LLM keys), do not hardcode them in code or commit them. Use Bauplan parameters or secrets.
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.

bauplan-skills CLAUDE.md is an instructions file published in the GitHub repository BauplanLabs/bauplan-skills (16 stars, last pushed 6d ago), licensed MIT. It adds 1,661 tokens to every session, about $0.0083 per session on Opus 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 2026-08-30.
