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 | $0.00059 | $0.01405 |
| Opus 5.5 | $0.00024 | $0.00562 |
| Sonnet 5.5 | $0.00012 | $0.00281 |
| Haiku 4.5 | $0.00006 | $0.00140 |
Grade A, and why
vault 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 28d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vault
The vault is a PARA-structured Obsidian brain. Other skills read and write it.
Location
VAULT=./work/vault # from the harness root
If there is no vault
Don't ask at session start. The first time a task needs the vault:
- Ask once: "Do you have an Obsidian vault? Where is it?"
- If they have one elsewhere, link it:
ln -s "<their vault>" work/vault. - If not, create it:
mkdir -p "work/vault/"{"01 Projects","02 Areas","03 Resources","04 Archive",Clippings}
Then carry on with the original task.
Structure
01 Projects/-- active work with an end02 Areas/-- ongoing interests03 Resources/-- reference material04 Archive/-- inactive items05 journal/-- yearly journalsClippings/-- saved articles and links inbox (categorize into PARA sections)Unsorted/-- secondary inbox for uncategorized links
Each subfolder has a :feed.md with a dataview query listing its contents by date added. :feed.md is the convention for "show me what's in this section."
Reading the vault
Use read, rg, or find directly against $VAULT. Examples:
# list a section
ls "$VAULT/02 Areas/Music/"
# literal search across the vault
rg -l "cowpunk" "$VAULT"
# show a section's feed
cat "$VAULT/02 Areas/Music/:feed.md"
For semantic search ("what notes feel related to X"), no tool exists yet -
fall back to rg with synonyms.
Recent activity
When asked "what's been happening recently in my vault" or "what's new":
# 1. Current journal -- newest entries at the bottom
read "$VAULT/05 journal/Journal.md"
read "$VAULT/05 journal/Journal $(date +%Y).md"
# 2. Most recently modified files across the vault (excludes dot dirs)
find "$VAULT" -name "*.md" \
-not -path "*/.obsidian/*" -not -path "*/.git/*" \
-exec stat -f "%m %Sm %N" {} + 2>/dev/null \
| sort -rn | head -30
# 3. Recently added files per section (by ctime = when file was created)
for section in "01 Projects" "02 Areas" "03 Resources"; do
find "$VAULT/$section" -name "*.md" -not -name ":feed.md" \
-exec stat -f "%m %Sm %N" {} + 2>/dev/null \
| sort -rn | head -10
echo "---"
done
# 4. Check inboxes
find "$VAULT/Clippings" -name "*.md" -mtime -30 2>/dev/null | sort
find "$VAULT/Unsorted" -name "*.md" -mtime -30 2>/dev/null | sort
What ships with it
4 files 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.

vault is a skill published in the GitHub repository scott-fryxell/brayness (125 stars, last pushed 29d ago), licensed MIT. It adds 59 tokens to every session and 1,405 once invoked, about $0.0002 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.
