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 | $0.00016 | $0.00246 |
| Opus 5.5 | $0.00006 | $0.00098 |
| Sonnet 5.5 | $0.00003 | $0.00049 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
cairn-init 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.
What it actually says
/cairn:cairn-init
Manually trigger the Cairn adoption flow. Equivalent to the
cairn-adopt skill, but invoked explicitly by the operator.
Useful when:
- The operator previously declined
[c]"never" and wants to retry. - The operator skipped
[b]"not now" and the 7-day re-prompt window hasn't elapsed yet. - The operator wants to re-adopt after deleting
.cairn/(e.g. starting fresh from a known baseline).
Behavior
Invoke the cairn-adopt skill. It owns the trigger gate, preflight,
init subprocess, and the phase-by-phase A/B/C surface.
If .cairn/ already exists, the skill detects this and surfaces:
Project is already Cairn-adopted.
[a]re-run init (warning: may overwrite ground state)[b]doctor (verify health)[c]cancel
Default to [c] cancel for safety.
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.

cairn-init is a command published in the GitHub repository isaacriehm/cairn (6 stars, last pushed 14d ago), licensed MIT. It adds 16 tokens to every session and 246 once invoked, about $0.0001 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 2026-08-31.
Other commands, from other repositories
tour
Tour this project's memory — what's captured, where it lives, how to recall it (core-memory-kit).
rosetta-grill
Grill the user about a plan or design — but grounded in Rosetta's resolved decision state — then RECORD the outcome as an ADR/PDR. Use when the user wants to stress-test a decision, says "grill me on this", or wants a decision interrogated and captured. Integrates grill-me-style interrogation with Rosetta's…
rosetta-preflight
Produce Rosetta's deterministic preflight JSON for a scoped change: optional RA1 structural report, decision-state resolution, and local Rosetta gates. Use before handing execution to a loop runner.
seed
Inspect the codebase and propose starter areas + topics for the wherefore log.
reflect
Synthesize patterns and a progress summary from milepost entries.
remember
Store something in the appropriate memory file. This command is the smart router for the memory system.
