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 | $0.00102 | $0.00821 |
| Opus 5.5 | $0.00041 | $0.00328 |
| Sonnet 5.5 | $0.00020 | $0.00164 |
| Haiku 4.5 | $0.00010 | $0.00082 |
Grade A, and why
patterns 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
Having problems that look like this?
- Out-of-date info — world-scanning.md
- Awareness of surroundings — world-scanning.md
- Getting ahead of problems — world-scanning.md
- Sending information or messages between computers — messaging.md
- Notifying another agent that something happened — messaging.md
- Reacting when the user opens their laptop, locks the screen, plugs in a USB, joins Wi-Fi, etc. — os-events-macos.md / os-events-windows.md / os-events-linux.md
- Hooking into anything the operating system already knows about — os-events-{macos,windows,linux}.md
- Scraping a site that has no API, especially behind a login wall — browser-automation.md
- Driving a SaaS dashboard to click a button or download a file — browser-automation.md
- Personal-data dashboards from services that don't expose one — browser-automation.md
- Need to wait for a human action (click, login, file drop) without burning tokens — async-tasks.md
- "Wake me up when X happens" where X is a one-shot event — async-tasks.md
- Pausing this conversation across an indeterminate wait without losing context — async-tasks.md
- Handing work to another agent (sub-agent, peer, fresh self) — multi-agent-handoff.md
- What survives across a fresh-context turn (async wake-up, schedule fire, compaction) — context-boundaries.md
- How to write journal entries that future-you / introspection-you will actually find useful — journal-as-breadcrumbs.md
- Picking the right temporal primitive (poller / schedule / loop / async-block / OS cron) — scheduling.md
- Building redundancy into channels, scrapers, sources without overengineering — fallback-chains.md
- Recognizing your own loops / runaway behavior and stopping yourself — circuit-breaker.md
- Stuck on something — what to do instead of grit (edit blocks, edit checkpoint.md, find conflicts) — try-harder.md
- The instinct to "try harder" / "do better" / "be more careful" — try-harder.md (almost always the wrong move)
- Two parallel things stepping on each other (schedules colliding, pollers in storm, double-messaging, oscillating state files) — coordination.md
- "It worked fine for weeks then suddenly two of X happened" — coordination.md (S2 collision)
- No durable place to track what you've noticed, committed to, or finished — interest-backlog.md
- "I should remember to look into X" / "that was weird but I don't have time now" — interest-backlog.md (log it, drain it later)
Two rules worth pulling forward
These show up repeatedly in the sub-pages but are easy to miss if you only skim the index.
- The artifact of trying harder is a diff someone else can verify, not a resolution someone else has to trust. If your "fix" is a commitment to do better, it dies the moment your turn ends. See
try-harder.md. - Journal entries should have handles, not prose.
j_abc123and/tmp/rl.mdsurvive a context boundary; "I spawned a job and will check on it" doesn't. Seejournal-as-breadcrumbs.md.
It's worth running a five-why's on your problem to see if some of this info applies.

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.

patterns is a skill published in the GitHub repository tkellogg/open-strix (93 stars, last pushed 2mo ago), licensed MIT. It adds 102 tokens to every session and 821 once invoked, about $0.0004 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.
