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 | $0.00134 | $0.02724 |
| Opus 5 | $0.00067 | $0.01362 |
| Sonnet 5 | $0.00027 | $0.00545 |
| Haiku 4.5 | $0.00013 | $0.00272 |
Grade A, and why
save-resource 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.
How it starts
The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
save-resource
Workhorse for getting things into Resources. Input is a source (file or content) + type + topic; output is a file at the canonical destination under <workspace.root>/<workspace.resources>/.
Before you begin: read the Configuration section in root CLAUDE.md. Path tokens like <workspace.resources> resolve to whatever's defined there — don't hardcode.
Why this exists
Resources is two-level (<workspace.resources>/<type>/<content>) and each type has a different convention — research uses YYYY-MM-<topic>-research/ folders, reference is flat, meetings is YYYY-MM-DD-<topic>.md. Doing this by hand means the user has to remember which type uses which convention. The skill enforces it.
This also means Inbox doesn't graveyard. The Inbox→Resources flow has a one-step path (/save-resource) instead of "manually decide where it goes, mkdir if needed, mv it, hope you got the naming right". Without it, items pile up in 0-Inbox forever (research finding from §2 constraint #1).
The skill also accepts CHAT CONTENT as a source, not just paths. If the user pastes notes and says "save this to research/X", the skill writes a new file at the destination — no Inbox round-trip required.
When to use
Trigger phrases (intentionally broad — over-trigger rather than miss):
- "save this to research" / "save this in reference" / "save this meeting note"
- "promote this to resources" / "this belongs in resources/"
- "file this as " / "save the X file in inbox to "
- "save as a " / "this is a meeting note for X"
- "/save-resource"
Do NOT trigger for:
- New project creation — that's
/new-project(which has acode-repobranch for repos) - Memory updates within an existing project — append directly to that project's
memory.md - Outputs <assistant.name> generates have dedicated subdirs inside Resources: briefings →
<workspace.resources>/briefings/, meeting-prep →<workspace.resources>/meeting-prep/, organization-reports →<workspace.resources>/organization-reports/./save-resourceis for user-supplied reference material (links, articles, snippets) — those land in<workspace.resources>/research/or<workspace.resources>/reference/.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

save-resource is a skill published in the GitHub repository the-sid-dani/second-brain-os (2 stars, last pushed 28d ago), licensed MIT. It adds 134 tokens to every session and 2,724 once invoked, about $0.0007 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.
Other skills, from other repositories
follower-onboard
Onboard a NEW family/team machine as a FOLLOWER-CONSUMER joining the multi-machine Claude+vault network. A follower READS the shared vault + canon + skills + memory as RECEIVE- ONLY data, runs nothing heavy locally (no RAG/reindex/GPU), and the hub never pushes executable hooks to it. Trigger on "/follower-onboard "…
claudeai-sync
One-command incremental sync of a claude.ai WEB account into the Obsidian vault — pull only new/changed chats, fold them in as notes (idempotent, never overwrites curated ones), extract artifacts as first-class notes, concept-link the new artifacts, refresh the RAG index + dashboard. Trigger on "/claudeai-sync", "pull…
chat-search
Search INSIDE past Claude Code sessions (the episodic "book of chats" index) — find which previous session discussed a topic, and continue it with one command. Uses a SEPARATE session index, NOT the curated-knowledge RAG, so raw chat noise never pollutes the distilled brain. Trigger on "/chat-search", "which chat…
five-hard
Five Hard Questions — monthly (or on demand) the second brain ITSELF asks the owner 5 hard questions about their own long-held beliefs and codex entries that haven't been revisited in a while. Prevents assumptions from fossilizing. Trigger on "/five-hard", "challenge my beliefs", "pressure-test my views". Part of the…
intake
Rule intake: one pass routes a new rule/preference/policy edit into ALL the right homes (always-loaded canon, memory, the behavioral Bible, a skill, a hook) and leaves a trace in the always-loaded layer so parallel processes see it on their own. Trigger on "/intake", "record this rule", "route this to its homes".…
canon-revision
Full structural REVISION of an always-loaded rules file (CLAUDE.md / MEMORY.md): build a TOP block of the most important rules + numbered categories, move rule bodies verbatim (a script moves bytes and proves 0 losses; the LLM decides only the mapping), fold heavy mechanics into trigger+gist+pointer form, then guards…
