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 | $0.00043 | $0.01114 |
| Opus 5 | $0.00022 | $0.00557 |
| Sonnet 5 | $0.00009 | $0.00223 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
sirs-criteria 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SIRS Criteria Calculation
The Systemic Inflammatory Response Syndrome (SIRS) criteria quantify the body's inflammatory response to insult — both infectious and non-infectious (trauma, burns, pancreatitis, major surgery). Defined by the 1992 ACCP/SCCM Consensus Conference, SIRS was historically used as part of the sepsis definition (SIRS >= 2 + suspected infection).
The 2016 SCCM Sepsis-3 consensus removed SIRS from the sepsis definition, replacing it with SOFA-based criteria (SOFA >= 2 + suspected infection). The rationale: SIRS criteria are overly sensitive and poorly specific for the dysregulated host response that defines sepsis. SIRS remains relevant for research comparing definitions, studying inflammatory response independent of infection, and legacy quality metrics.
M4Bench Use
In M4Bench, target concept tables listed in the task configuration are removed or unavailable in the agent database. Use this skill as procedural guidance and derive the requested output from available source or intermediate tables; do not rely on a precomputed target table or bundled SQL script.
SIRS Criteria (0-4 Points)
Each criterion met = 1 point:
| Criterion | Threshold |
|---|---|
| Temperature | < 36°C OR > 38°C |
| Heart Rate | > 90 bpm |
| Respiratory | RR > 20/min OR PaCO2 < 32 mmHg |
| WBC | < 4 OR > 12 x10^9/L OR > 10% bands |
SIRS Positive: >= 2 criteria met
Critical Implementation Notes
-
Band Forms: The presence of > 10% immature neutrophils (bands) satisfies the WBC criterion, even if total WBC is within normal range. Band counts are variably documented across datasets.
-
PaCO2 Source: Should use only arterial blood gas specimens. Venous or mixed venous PaCO2 is unreliable for this criterion. In MIMIC-IV, filter by specimen type
'ART.'using the specimen itemid 52033 inlabevents. -
Time Window: The original definition does not specify a time window. Most ICU implementations use the first 24 hours, but the criteria can be applied to any clinically relevant window. Include measurements from 6 hours before ICU admission to capture ED data.
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.

sirs-criteria is a skill published in the GitHub repository hannesill/m4 (43 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 1,114 once invoked, about $0.0002 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 2026-08-30.
