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 | $0.00046 | $0.00432 |
| Opus 5 | $0.00023 | $0.00216 |
| Sonnet 5 | $0.00009 | $0.00086 |
| Haiku 4.5 | $0.00005 | $0.00043 |
Grade A, and why
start-session 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 4d 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
second-brain: start-session
Read-only. Restores context; writes nothing.
Steps
- Locate the vault (cwd or ancestors containing
Projects/Dashboard.md; else registered vaults in~/.claude/second-brain/vaults, ask if several). None → "run /second-brain:setup first." - Vault brief from
Projects/Dashboard.md+Projects/_AUTO_status.md, tersely:- 🔴 blocked / ⏰ deadline rows first
- 🟢 active rows: Last session + Next from the Dashboard
- dirty worktrees from
_AUTO_status.mdworth committing
- Repo thread — if the user named a repo or cwd is inside one, read
Projects/<repo>.mdand restore:Last handoff (@
last_handoff_commit): <Last: content> Next (intent): <Next: content> - Mechanical drift check for that repo:
git -C <repo> log --oneline <last_handoff_commit>..HEAD→ N commits since handoff. N>0 → "⚠️ N commits since last handoff:" + subjects; the recorded thread may be stale.last_handoff_commit: none(auto-stub) → "never handed off yet — onboard with /second-brain:analyze ."- Note contradicts git facts (branch mismatch, note claims work git doesn't show) → say so and recommend /second-brain:analyze. Never silently trust a stale note.
- End with: "Pick up where you left off — ?"
Rules
- Writes nothing. Missing/stale notes → recommend the right command, don't fix here.
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.

start-session is a skill published in the GitHub repository Imtylerrrrrr/second-brain (1 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 432 once invoked, about $0.0002 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 2026-08-31.

setup
Scaffold the handoff project-memory system into THIS repository (new or existing) — copies the template tree into .handoff/, then runs a guided discovery pass that drafts a real STATUS, MAP, TECHSTACK, and PRODUCT from the actual codebase and confirms with the user before saving. Use when the user says "set up…
memory-recall
Search and recall relevant memories from past sessions via memsearch. Use when the user's question could benefit from historical context, past decisions, debugging notes, previous conversations, or project knowledge -- especially questions like 'what did I decide about X', 'why did we do Y', or 'have I seen this…
wiki
Markdown-first knowledge base where the LLM acts as librarian. Ingests raw sources, compiles and interlinks topic files, self-maintains an index. No vector DB or embeddings required -- uses LLM-native navigation over structured markdown up to 400K words.
alive:session-history
Revive sessions (quick or heavy), browse, and search — 'what happened recently?', 'find the session where we discussed X', 'revive yesterday's session'. For single-session recall and multi-session browsing. If the human needs to merge multiple sessions into one working context or detect conflicts between parallel…
unslop-file
Humanize natural-language memory files (CLAUDE.md, todos, preferences, docs) by removing AI-isms and adding burstiness while preserving every code block, URL, path, command, and heading exactly. Two modes: --deterministic (fast, regex-based, no API) and LLM (default, calls Claude for rewrite). Humanized version…
