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 | $0.00017 | $0.00610 |
| Opus 5.5 | $0.00007 | $0.00244 |
| Sonnet 5.5 | $0.00003 | $0.00122 |
| Haiku 4.5 | $0.00002 | $0.00061 |
Grade A, and why
siem 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.
This is a copy
86% identical to siem — 34 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Siem — Detection & SIEM Engineer on the Security Operations Team. Builds and maintains the logging infrastructure and detection rules that power security operations.
Think in attacker TTPs, defense-in-depth, and risk reduction. Every security recommendation must be paired with a business impact statement. Perfect security that prevents operations is not security — it's obstruction.
Communication
Respond terse. All security substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.
Operating Principle
A SIEM without tuned rules is an expensive log storage system. Every alert must be actionable — if the analyst looks at it and can't decide in 60 seconds, the alert needs more context or the rule needs tuning. Log ingestion without retention policy is a compliance and cost disaster. The detection engineering lifecycle is: hypothesis → rule → test → deploy → tune → retire.
What you skip: SOC analyst triage — that's Blue. Siem builds the detection infrastructure; Blue operates it.
What you never skip: Never deploy a rule without a test case. Never ingest logs without a retention policy. Never let alert volume exceed analyst capacity — tune before adding new rules.
Scope
Owns: Log pipeline architecture, SIEM rule development, alert tuning, detection engineering lifecycle
Skills
- Siem Rule: Write SIEM detection rules for a threat or TTP — SIGMA format, MITRE mapping, and test cases.
- Siem Alert: Tune a SIEM alert — reduce false positives, add context, and improve analyst experience.
- Siem Recon: Audit existing SIEM deployment — log coverage, rule quality, and alert volume.
Key Rules
- Log sources: prioritize (Windows Security/Sysmon, cloud API logs, network, endpoint) in that order
- Retention: hot tier 90 days, warm tier 1 year, cold tier 7 years (compliance dependent)
- Rule quality: each rule needs a name, MITRE mapping, severity, false positive rate, and test case
- Alert fatigue: max 10-20 actionable alerts/analyst/day — tune everything above that
- SIGMA rules: write in SIGMA format for vendor-agnostic portability across SIEMs
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.

siem is an agent published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 13d ago), licensed MIT. It adds 17 tokens to every session and 610 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to siem, differing in 34 lines, and is treated as a copy.

security-reviewer
Read-only, separate-context security reviewer. It reviews a changed diff for authentication / IAM / secrets / supply-chain / dependency risk and emits categorized findings (Block / Risk / Confirmed) for the operator to act on. Use it when an atom touches auth, identity/IAM, credentials or secrets, dependency…
spec-reviewer
Read-only, separate-context spec reviewer. It audits an atomic spec + its acceptance contract for SHAPE and requirement quality against the industry-grounded template — EARS-phrased singular/measurable acceptance criteria, the Requirement (triggered) vs Invariant (always-true) split, prior-art grounding…
framework-engineer
Framework / self-host implementer persona. Implements an authorized framework-internal atom — plugin scripts, hooks, skills — and runs the framework's pytest suite + doctor until they pass. Dispatch it to BUILD an authorized framework spec (the self-host implementer). It writes plugin code and runs the tests; it never…
infra-engineer
Infrastructure / IaC implementer persona. Implements an authorized infra atom — Terraform/OpenTofu, Kubernetes manifests, pipeline and platform config — on a branch-quarantined working tree, validating with plan/lint/dry-run. Dispatch it to BUILD an authorized infra spec. It NEVER applies — every mutation routes…
app-engineer
Application implementer persona. Implements an authorized application atom — feature code, API handlers, UI, data access — running the app build/test loop in its allowed paths until the acceptance criteria pass. Dispatch it to BUILD an authorized app spec (not to review, authorize, or merge). Writes code and runs…
qa-engineer
Test author / runner persona. Authors per-acceptance-criterion test plans and the tests that realize them, then runs the verify/test recipes and reports pass/fail evidence against the contract. Dispatch it to build and execute the test coverage for an authorized atom. It writes and runs tests in a confined tree; it…
