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.
npx agentmods add instructions/brandonhorst/materialize-base/agents-mdgit clone --depth 1 https://github.com/brandonhorst/materialize-baseWhat 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 | $0.00710 | $0.00710 |
| Opus 5 | $0.00355 | $0.00355 |
| Sonnet 5 | $0.00142 | $0.00142 |
| Haiku 4.5 | $0.00071 | $0.00071 |
Grade A, and why
materialize-base AGENTS.md 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 2d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
This is a Deno CLI to read Obsidian Bases files, and query an Obsidian vault accordingly, and return the output in markdown. Obsidian provides no API for this, so we're doing it ourselves.
Scraped Obsidian Bases docs are all provided in obsidian-base-docs/.
Project Structure & Module Organization
Core CLI logic lives in module.ts, which wires together runtime flags and
orchestrates vault queries. Supporting utilities sit under src/, e.g.
src/materalize.ts for query planning, src/parse-file.ts for Obsidian
markdown ingestion, and src/types.ts for shared interfaces. Tests reside in
test/ as *.test.ts files mirroring their source counterparts. Scraped
reference material is kept in obsidian-base-docs/; treat it as read-only
documentation inputs. Configuration for tasks, formatting, and dependency
imports is centralized in deno.json.
Documentation
README.mdcovers CLI usage, expected permissions, and the--vaultand--viewflags for controlling output.vendor/SKILL.mdmirrors the CLI instructions for the Claude skill variant and reiterates the optional--vaultoverride.obsidian-base-docs/stores scraped Obsidian Bases documentation for reference only; do not modify.
Build, Test, and Development Commands
deno task check: Run formatter, linter, and type-check to keep the codebase healthy.deno task test: Execute all unit tests undertest/.deno task coverage: Generate coverage data intocov_profile/and report totals.deno task demo: Try the CLI end-to-end with a local base definition.
Coding Style & Naming Conventions
Default to 2-space indentation and rely on deno fmt for layout. Prefer
TypeScript readonly modifiers for data passed across modules, and use explicit
return types on exported functions. Follow camelCase for variables and
functions, PascalCase for types and classes, and kebab-case for new filenames.
Imports should be relative within src/ and managed via deno.json when
pulling from @std.
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.

materialize-base AGENTS.md is an instructions file published in the GitHub repository brandonhorst/materialize-base (5 stars, last pushed 10mo ago), licensed MIT. It adds 710 tokens to every session, about $0.0036 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.
