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.

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 | $0.00012 | $0.00226 |
| Opus 5 | $0.00006 | $0.00113 |
| Sonnet 5 | $0.00002 | $0.00045 |
| Haiku 4.5 | $0.00001 | $0.00023 |
Grade A, and why
Filter Signals 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 10d 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
Input
Incoming signals (new emails, Teams messages, GitHub notifications), user profile.
Output (JSON)
{
"signals": [{
"description": "Email from Jane about cost optimization review",
"source_breadcrumb": "Outlook: Re: Cost optimization review",
"relevance": 0.9,
"pass_reason": "matches focus_area: cost optimization"
}]
}
Instructions
- Auto-pass (relevance=1.0): flagged, saved, direct @mention, GitHub review_requested, GitHub assigned. pass_reason = "flagged"/"saved"/"direct mention"/"review requested"/"assigned".
- Others: score 0-1 based on overlap with profile's focus_areas, key_contacts, active_threads.
- Include if relevance ≥ 0.4. Write pass_reason explaining which profile element matched.
- Below threshold: silently drop.
- Max 10 signals. Sort by relevance descending.
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.

Filter Signals is a skill published in the GitHub repository YuiZhou/dayarc-agent (2 stars, last pushed 15d ago), licensed MIT. It adds 12 tokens to every session and 226 once invoked, about $0.0001 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.
