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 | $0.00063 | $0.03433 |
| Opus 5 | $0.00032 | $0.01716 |
| Sonnet 5 | $0.00013 | $0.00687 |
| Haiku 4.5 | $0.00006 | $0.00343 |
Grade A, and why
obsidian-bases 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.
This is a copy
100% identical to obsidian-bases — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Obsidian Bases Skill
Workflow
- Create the file: Create a
.basefile in the vault with valid YAML content - Define scope: Add
filtersto select which notes appear (by tag, folder, property, or date) - Add formulas (optional): Define computed properties in the
formulassection - Configure views: Add one or more views (
table,cards,list, ormap) withorderspecifying which properties to display - Validate: Verify the file is valid YAML with no syntax errors. Check that all referenced properties and formulas exist. Common issues: unquoted strings containing special YAML characters, mismatched quotes in formula expressions, referencing
formula.Xwithout definingXinformulas - Test in Obsidian: Open the
.basefile in Obsidian to confirm the view renders correctly. If it shows a YAML error, check quoting rules below
Schema
Base files use the .base extension and contain valid YAML.
# Global filters apply to ALL views in the base
filters:
# Can be a single filter string
# OR a recursive filter object with and/or/not
and: []

# Define formula properties that can be used across all views
formulas:
formula_name: 'expression'
# Configure display names and settings for properties
properties:

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.

obsidian-bases is a skill published in the GitHub repository michaeljauk/brain-starter (5 stars, last pushed 13d ago), licensed MIT. It adds 63 tokens to every session and 3,433 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to obsidian-bases, differing in 14 lines, and is treated as a copy.

api-canvas
DataCanvas primitive reference — a Tier 3 SQL/analytical workspace for tabular MCP servers, backed by DuckDB. Use when registering tables from upstream APIs, running ad-hoc SQL across them, and exporting results. Covers the acquire → register → query → export flow, per-table TTL, the token-sharing pattern for…
api-mirror
Stand up a persistent, self-refreshing local mirror of a bulk upstream dataset with the MirrorService (@cyanheads/mcp-ts-core/mirror). Use when a server wraps a large or slow API and should query a synced local index (embedded SQLite + FTS5) instead of paginating the live API per request.
obsidian-md2wechat
Format the current Obsidian article with the existing md2wechat CLI and return its preview to the Obsidian publishing plugin. Use when the user asks to typeset an Obsidian note for WeChat.
lineage
Use when user invokes /lineage with a column name (optionally qualified with table/schema). Also triggers on "trace this column", "where does X come from", "what reads from Y table". Traces column-level data lineage through SQL, Kafka, Spark, JDBC, and ORM codebases. Produces a structured lineage path with confidence…
pos-verify
Use this immediately after files are created, edited, moved, deleted, or materially rewritten inside PersonalOS. Verifies that new truth was routed to the correct owner, written in the correct file shape, and still follows POS conventions. Do NOT use for whole-vault deep audits; use system-health-check.
skillify
Use this when {{username}} asks to skillify a repeated workflow, determine whether it deserves a reusable PersonalOS skill, or harden an existing workflow into a tested resolver-reachable capability. Do NOT use for one-off notes, ordinary execution, or already-specified skill authoring; use write-skill.
