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.

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 | $0.00107 | $0.01059 |
| Opus 5 | $0.00053 | $0.00530 |
| Sonnet 5 | $0.00021 | $0.00212 |
| Haiku 4.5 | $0.00011 | $0.00106 |
Grade A, and why
vaultr-index-knowledge 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 9d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vaultr Index Knowledge
Scans the knowledge directory, finds units not yet in any index, and adds them. Running this skill repeatedly is safe and always converges — it only ever adds missing entries, never rewrites existing ones.
Domain index files live at <knowledge-dir>/_indexes/<Domain>.md. The compile skill matches a note to a domain by the index filename alone (e.g. AI.md, Business.md).
A unit may appear in at most 2 indexes: one primary domain, one secondary only when the unit genuinely straddles two.
Run all steps to completion without stopping. Only speak at the end (Step 4 summary).
Inputs
- Knowledge directory — default:
_knowledge/(relative to cwd, which is always the vault root)
The index directory is always <knowledge-dir>/_indexes/. Create it if it does not exist.
Step 1 — Find unindexed units
Scan all knowledge units:
find <knowledge-dir> -name "*.md" -not -path "*/_indexes/*" | sort
Scan all existing index files and collect every Path value from their tables:
find <index-dir> -name "*.md" | sort
A unit is unindexed if its vault-absolute path (e.g. /_knowledge/Vertical Agent.md) does not appear in any index table. Build a list of only these units.
If all units are already indexed, report and stop.
Step 2 — Read unindexed units
For each unindexed unit, read its YAML front matter and first non-heading paragraph. Build an internal list:
references/extract.md documents partial-read commands — vaultr extract tag retrieves front-matter tags directly; vaultr extract segment --head N retrieves the opening lines. Use them instead of a full vaultr read when only these fragments are needed.
title | entity_type | tags | summary (≤80 chars) | vault-absolute path
Vertical Agent | concept | [ai, agent] | AI product focused on a specific vertical domain | /_knowledge/Vertical Agent.md
Jane Smith | person | [founder, ai] | Founder of SophiaPro, AI startup | /_knowledge/Jane Smith.md
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.

vaultr-index-knowledge is a skill published in the GitHub repository skoowoo/vaultr-notes (90 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 107 tokens to every session and 1,059 once invoked, about $0.0005 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.

copilot-spaces
Use Copilot Spaces to provide project-specific context to conversations. Use this skill when users mention a "Copilot space", want to load context from a shared knowledge base, discover available spaces, or ask questions grounded in curated project documentation, code, and instructions.
skill-authoring
Create, revise, or remove reusable procedural and interactive skills; use memorystore for facts and preferences.

Scan recent agent sessions for repeated friction, corrections, approvals, workflow patterns, and packaging candidates. Use when asked to find signals, friction, recurring manual workflows, missing skills, prompt improvements, or automation opportunities from recent Codex/Pi work.
caveman-compress
Compress natural language memory files (CLAUDE.md, todos, preferences) into caveman format to save input tokens. Preserves all technical substance, code, URLs, and structure. Compressed version overwrites the original file. Human-readable backup saved as FILE.original.md. Trigger: /caveman-compress FILEPATH or…
