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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 95 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
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 | $0.00036 | $0.00616 |
| Opus 5 | $0.00018 | $0.00308 |
| Sonnet 5 | $0.00007 | $0.00123 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
session-artifact-indexing 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 10d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session Artifact Indexing
Use this skill when a session creates or references several documents, trackers, plans, templates, source links, or skills that the user may need later.
Primary trigger phrases:
- “I lose track of things”
- “put the links somewhere”
- “make a note”
- “save the documents from this session”
- “where are the files from this?”
- Any multi-step work that creates 3+ durable files and ends with a natural handoff/checkpoint
The goal is not to duplicate all work. The goal is to create one clean index that the user can open later.
Default Destination
For Apple Notes, use the user’s dedicated assistant folder:
⭐ Hermes - Assistant
If the task is explicitly Obsidian-first, use the relevant vault note instead. If the user asks for Apple Notes, use Apple Notes.
What to Include
Create a titled note with grouped links:
- Main planning / brainstorm docs
- Working files / trackers
- Templates
- Skills created or updated
- Existing reference files used
- External public-source links
- Current priority / next step, if the session established one
Use:
file://links for local files- normal
https://links for web sources - readable labels, not raw path dumps only
Apple Notes Creation Pattern
For large note bodies, write an AppleScript file first and then run it with osascript.
Do not inline long AppleScript with HTML through a single shell command if the body contains & or &; command safety scanning may interpret ampersands as shell backgrounding. Writing the script file first is cleaner and avoids false positives.
Verification
Always verify the note exists before reporting success:
memo notes -f '⭐ Hermes - Assistant' 2>&1 | grep -i 'NOTE TITLE'
Report back with:
- note title
- folder name
- a concise list of included link groups
Quality Bar
Good index note:
- Has a clear title
- Explains why it exists in one sentence
- Groups links logically
- Uses clickable local and web links
- Does not bury the user in full transcripts
- Gives him one place to resume from
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.

session-artifact-indexing is a skill published in the GitHub repository AtlasOmnia/donna-starter (110 stars, last pushed 10d ago), licensed MIT. It adds 36 tokens to every session and 616 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 2026-08-30.
Other skills, from other repositories
session-artifact-indexing
Use this skill when a session creates or references several documents, trackers, plans, templates, source links, or skills that the user may need later.
google-workspace
Gmail, Calendar, Drive, Contacts, Sheets, and Docs — through Hermes-managed OAuth and a thin CLI wrapper. When gws is installed, the skill uses it as the execution backend for broader Google Workspace coverage; otherwise it falls back to the bundled Python client implementation.
apple-notes
Interact with the Apple Notes app. CRUD operations for persistent storage of thoughts, data, and information across sessions.
vault-organization
Audit and reorganize the user's Obsidian vault. Run when asked to organize, clean up, or audit the vault structure — or to set up a sensible structure for a new/empty vault.
