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 | $0.00074 | $0.00415 |
| Opus 5.5 | $0.00030 | $0.00166 |
| Sonnet 5.5 | $0.00015 | $0.00083 |
| Haiku 4.5 | $0.00007 | $0.00042 |
Grade A, and why
lamina-systems 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 1mo 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
Lamina Systems
Reference-loading protocol
- Match the request's primary system question to one row below.
- Open that linked reference before answering. Add another only when a second question materially changes the answer; do not preload the directory.
- Start the response with
Using lamina-systems: <topic path(s)>so the selected system lens is auditable.
Topic index
| System signal | Read | Adds |
|---|---|---|
| Need to map purpose, elements, relationships, stocks, flows, or delays | System Structure | a coherent system boundary before screen design |
| Local fixes recur, backfire, shift burden, or create unfair resource use | System Traps | named structural failure patterns and responses |
| Need to choose between copy/UI tweaks, information changes, rules, or goals | Leverage Points | intervention ranking by structural leverage |
| Outputs amplify or balance future inputs, especially with visible delay | Feedback Loops | reinforcing/balancing loops and oscillation risks |
| Need safe change under uncertainty or protection against rule regression | Evolutionary Rules | reversible choices, deferred commitment, and invariant rechecks |
Working rule
Use the smallest sufficient reference set. Diagnose recurring behavior with system traps + feedback loops, then use leverage points to choose an intervention. Add evolutionary rules only when the question includes rollout, reversibility, or future change.
What ships with it
5 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.

lamina-systems is a skill published in the GitHub repository aryaniyaps/lamina (121 stars, last pushed 10d ago), licensed Apache-2.0. It adds 74 tokens to every session and 415 once invoked, about $0.0003 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.
