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 | $0.00034 | $0.00381 |
| Opus 5.5 | $0.00014 | $0.00152 |
| Sonnet 5.5 | $0.00007 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
microcoreos-architecture 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 2mo 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.
What it actually says
MicroCoreOS Architecture Skill
Read AGENTS.md and follow the route for your role. That table names the
one or two files your role needs and, just as importantly, the ones it must not
open — a Planner that also loads the plugin templates spends ~3,000 tokens on
code it will never write.
This file deliberately holds no rules, no reading path and no checklist of its own. It is a routing table and nothing else: every row points at the one place that owns its subject. Add a rule, a path or a checklist here and it becomes a rival copy of something canonical — which is the one failure this file exists to prevent.
| You need | It is in |
|---|---|
| The rules | AGENTS.md § Non-Negotiable Rules (canonical) |
| Kernel/tool/event-bus laws | AGENTS.md § Core Architectural Laws |
| The plugin template | AI_CONTEXT.md § Plugin Authoring Guide (regenerated every boot) |
| What exists right now | AI_CONTEXT.md § Available Tools / § Domains |
| The plan format and its 18 rules | docs/PARALLEL_DEVELOPMENT.md § Phase 1 |
| Anti-patterns, testing, building a tool | INSTRUCTIONS_FOR_AI.md |
Before you finish, the gates are commands, not a checklist to eyeball:
microcoreos plan validate # the plan is a contract — zero errors
uv run -m pytest # green
microcoreos status # manifest still describes the code on disk
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.

microcoreos-architecture is a skill published in the GitHub repository theanibalos/MicroCoreOS (22 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 381 once invoked, about $0.0001 per session on Opus 5.5. 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.
