Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00142 | $0.02212 |
| Opus 5 | $0.00071 | $0.01106 |
| Sonnet 5 | $0.00028 | $0.00442 |
| Haiku 4.5 | $0.00014 | $0.00221 |
Grade A, and why
monospace scanned grade A with 1 finding 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**Troubleshooting:** `curl -s -o /dev/null -w "%{http_code}" -X POST https://<host>/api/<workspace>/mcp` — a `401` means it's up but unauthenticated (expected without a token); `403` means the credential is valid but for How it starts

Monospace
Drive a Monospace instance from an agent: query and mutate data via the REST API or the typed SDK, generate instance-correct types, and use the MCP server. This page is a router — read the principles and the inline traps, then load the reference for the task.
Core principles
1. You almost certainly don't know this API. Don't guess — use the ground truth.
Monospace is not in most training data, so do not invent endpoints, SDK methods, or types from memory. The SDK is @monospace/sdk (createClient + per-collection delegates). Get the real shape from generated types (npx @monospace/sdk generate) or the live OpenAPI doc (GET /api/<workspace>/openapi), plus the references below. (If you happen to know Directus: it is a different product — don't assume its APIs carry over.)
2. Generate types, then write against them.
The most reliable way to get the data shape right is to generate a typed client from the running instance: npx @monospace/sdk generate reads the live OpenAPI document and emits a typed client matching that instance's schema. Prefer generated types over hand-written shapes. See references/sdk.md.
3. Verify against current docs / OpenAPI before implementing.
For anything not covered here, fetch the canonical OpenAPI doc (GET /api/<workspace>/openapi, or /api/system/openapi) or the Monospace docs. The OpenAPI doc is generated from the live schema, so it is always correct for the instance.
4. Inspect before you mutate, then verify. Read the schema / list items (read-only) before writing. After a write, read it back to confirm. A change without verification is incomplete.
5. Recover, don't loop.
If an approach fails 2-3 times, stop and reconsider — check the error body (it carries a message), the schema, and permissions. Retrying the same call rarely fixes it.
Critical traps (read before writing any data code)
These are verified, easy-to-miss behaviors. Getting them wrong fails silently.
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.

monospace is a skill published in the GitHub repository directus/monospace-agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 142 tokens to every session and 2,212 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
