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 | $0.00061 | $0.01035 |
| Opus 5 | $0.00030 | $0.00517 |
| Sonnet 5 | $0.00012 | $0.00207 |
| Haiku 4.5 | $0.00006 | $0.00103 |
Grade A, and why
create 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 yesterday.
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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Note
Write a Markdown note into the Obsidian vault Claude Code is running in. This skill owns vault conventions — callers supply content, not layout.
Input
$ARGUMENTS:
--title(required) — note title, also the filename--content(required) — Markdown body--folder(optional) — subfolder within the vault; defaults to the vault root--frontmatter(optional) — JSON object of extra frontmatter fields
Step 1 — Locate the vault
Walk up from the current working directory looking for a .obsidian/ directory. The first ancestor containing one is the vault root.
d="$PWD"
while [ "$d" != "/" ]; do
[ -d "$d/.obsidian" ] && { echo "$d"; break; }
d="$(dirname "$d")"
done
If no .obsidian/ is found, stop and say so — do not guess a path and do not write outside a vault. Ask the user to run from inside their vault or to name the target vault explicitly.
There is no config file. The vault is wherever the session is.
Step 2 — Read the vault's conventions
If the vault root has a CLAUDE.md, read it first and follow any conventions it states — folder layout, frontmatter fields, tagging, wikilink rules, daily-note behaviour. A vault's own documented conventions override the defaults below.
Reading it is not optional and neither is acting on it. Delegation here has silently failed before: a clipping was written correctly and its daily-note link was never added, because "follow any conventions it states" was treated as advisory. Steps 3a and 3b make the two that are almost always stated explicit.
Step 3 — Build the note
Filename — from the title, with / \ : * ? " < > | replaced by -, and whitespace trimmed. If the file already exists, append 2, 3, … rather than overwriting.
Frontmatter — always include title and created (today, YYYY-MM-DD), then merge in anything from --frontmatter. Preserve the caller's values on conflict.
Folder — --folder if given, else the vault root. Create the folder if it does not exist.
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.

create is a skill published in the GitHub repository mayank-io/mstack (5 stars, last pushed 7d ago), licensed MIT. It adds 61 tokens to every session and 1,035 once invoked, about $0.0003 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.
