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 | $0.00555 |
| Opus 5.5 | $0.00006 | $0.00222 |
| Sonnet 5.5 | $0.00003 | $0.00111 |
| Haiku 4.5 | $0.00002 | $0.00056 |
Grade A, and why
mb-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
/mb-init — Route external Memory Bank bootstrap
node <devrails-checkout>/scripts/install-framework.mjs --bootstrap-only --target <target-repo> --yes
-
For an explicit framework sync request on an existing target, update runtime command skills and Memory Bank managed assets from the same prepared source copy:
node <devrails-checkout>/scripts/install-framework.mjs --bootstrap --sync --target <target-repo> --yes -
--bootstrap-only --syncrepairs only Memory Bank managed assets and does not update runtime command skills. Do not present it as a full framework sync. -
Do not run local bootstrap logic, copy a helper into the target, install a dependency, or create the skeleton manually. The external installer owns bootstrap and its existing target-file safety policy.
-
If the DevRails checkout is unknown or unavailable, stop with a blocker: ask the operator to provide an available checkout path or run the external installer action, then rerun
/mb-init. Do not present a placeholder as an executable command.
<handoff_contract>
- After a successful external bootstrap or sync, rerun
/mb-initto confirm.memory-bank/is present. - If the Memory Bank is present and no sync was requested, make no changes and
hand off to
/startonly when itsSKILL.mdexists in the active.agents/skills/or.claude/skills/runtime surface. Otherwise report that the skeleton is ready and stop; do not claim/startis available. Runtime command installation remains an explicit external installer action. </handoff_contract>
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.

mb-init is a command published in the GitHub repository nicelight/DevRails-26 (23 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 555 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 2026-08-30.
Other commands, from other repositories
minutes-ideas
Surface recent voice memos and ideas captured from any device. Use when the user asks "what ideas did I have?", "what were my recent memos?", "what did I record while walking?", or wants to recall a captured thought.
learn
Force claude-smart to extract learnings from this session now.
memory-store
Store an insight, decision, or pattern to memory.
analyze-context
USE WHEN you want to analyze project context before starting work on a task. Calls context + recall, then synthesizes goals, decisions, gotchas, and relevant memories into a pre-task brief.
cc-memory
Configure persistent memory that survives across sessions using a layered approach: split rule files for always-loaded context, auto-memory for organic learning, and optional MCP-backed long-term memory for large codebases.
lians-recall
Recall current (non-stale) facts from Lians memory, optionally as-of a past date.
