siem-operations skillA
siem-operations is agent-read markdown (skill) from miosa-osa/osa: Validate SIEM ingestion, parsing, alert routing and retention with synthetic canaries and timestamp evidence. Use for SIEM operations, missing events, alert pipeline outages, duplicate events or detection delivery checks..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Siem Operations ## Workflow 1. Map producer, collector, parser, index, query, alert and destination; identify which stages are actually accessible. 2. Record expected volume, source coverage and ingestion delay. Read the synthetic canary workflow. 3. Test a harmless uniquely identified event through the authorized test pipeline and trace every stage. 4. Compare event time with receipt time; inspect parse failures, deduplication, rate limits and clock skew. 5. Run one alerting fixture and one benign control, preserving query version and delivery receipt. A search hit does not prove alert delivery. 6. Roll back changed rules/pipelines on regressions; distinguish restored ingestion from recovered historical gaps. ## Worked example and prerequisites Read [references/workflow.md](references/workflow.md) before execution. Use only registered OSA tools named in the frontmatter; command examples run through `shell_execute`. Check `command -v` for each external executable on the actual target. Optional packages, external collectors and vendor accounts are not bundled or presumed installed. ## Evidence and completion …

How to install
mdr add miosa-osa/osa/siem-operations@v1.0.200mdr add miosa-osa/osa/siem-operations@sha256:526ecfbcfe80241bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
