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 | $0.00021 | $0.02177 |
| Opus 5.5 | $0.00008 | $0.00871 |
| Sonnet 5.5 | $0.00004 | $0.00435 |
| Haiku 4.5 | $0.00002 | $0.00218 |
Grade A, and why
setup-cursor-copies 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 1mo 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.
This is a copy
89% identical to setup-cursor-copies — 29 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Setup Foundation Cursor Copies
Sets up foundation cursor rules and commands in .cursor/. When foundation is a git submodule, creates symlinks (stays in sync with git submodule update). Otherwise creates independent copies.
Command
setup_cursor_copies
or
setup cursor copies
Purpose
This command runs the foundation setup script (foundation/scripts/setup_cursor_copies.sh) which:
- If foundation is a git submodule: Delegates to
setup_cursor_rules.shand creates symlinks from foundation to.cursor/(single source of truth; updates apply withgit submodule update). - Otherwise: Creates independent copies of foundation rules/commands in
.cursor/. - Uses original filenames (no prefix).
- Removes existing foundation files before creating new ones.
- Preserves any non-foundation files (custom rules/commands).
When run from the foundation repository itself, it also automatically runs the setup script in peer repositories (located at ../*) that include this foundation repo via symlink.
When to Use
- Submodule: Run after
git submodule update(or any setup); symlinks keep.cursor/in sync automatically. - Copy mode (foundation not a submodule): When you want independent copies, need to customize rules, symlinks are not suitable, or you version-control your own copies. Re-run after foundation updates to refresh.
Submodule vs copy behavior
When foundation is a git submodule (this command delegates to setup_cursor_rules):
- Creates symlinks to foundation (single source of truth)
- Updates automatically when foundation changes (
git submodule update) - Cannot customize foundation rules without breaking the link
When foundation is a symlink or copy (this command uses copy mode):
- Creates independent file copies
- Uses original filenames (no prefix)
- Does NOT update automatically when foundation changes
- Can be customized per repository
- Must re-run script to get foundation updates
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.

setup-cursor-copies is a skill published in the GitHub repository markmhendrickson/foundation (2 stars, last pushed 2mo ago), licensed MIT. It adds 21 tokens to every session and 2,177 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 89% identical to setup-cursor-copies, differing in 29 lines, and is treated as a copy.
