What is close-case-artifact?

A procedure for closing a security case or alert with a required reason, root cause, and written explanation. It distinguishes confirmed threats, harmless activity, maintenance, inconclusive results, and unknown causes.

Use it after triage or investigation to close a case or alert, record its cause, add a justification, and optionally apply tags or assignment details.

It prevents security records from being closed without explaining what happened and why the investigation ended.

Token cost

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	$0.00045	$0.00682
Opus 5.5	$0.00018	$0.00273
Sonnet 5.5	$0.00009	$0.00136
Haiku 4.5	$0.00005	$0.00068

Security

Grade A, and why

close-case-artifact 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 2mo 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.

Close Case Artifact Skill

Close a case or alert with the required reason, root cause, and justification comment.

Inputs

ARTIFACT_ID - The ID of the case or alert to close
ARTIFACT_TYPE - Either "Case" or "Alert"
CLOSURE_REASON - Must be one of:
- MALICIOUS - Confirmed threat
- NOT_MALICIOUS - False positive or benign
- MAINTENANCE - System/maintenance activity
- INCONCLUSIVE - Unable to determine
- UNKNOWN - Unknown/other
ROOT_CAUSE - Must match a predefined root cause (use get_case_settings_root_causes to list options)
CLOSURE_COMMENT - Detailed justification for closure
(Optional) ALERT_GROUP_IDENTIFIERS - Alert group identifiers
(Optional, for alerts) ASSIGN_TO_USER - User to assign closed alert to
(Optional, for alerts) TAGS - Comma-separated tags

Workflow

Step 1: Execute Closure

For Cases:

secops-soar.siemplify_close_case(
    case_id=ARTIFACT_ID,
    reason=CLOSURE_REASON,
    root_cause=ROOT_CAUSE,
    comment=CLOSURE_COMMENT,
    alert_group_identifiers=ALERT_GROUP_IDENTIFIERS
)

For Alerts:

secops-soar.siemplify_close_alert(
    alert_id=ARTIFACT_ID,
    reason=CLOSURE_REASON,
    root_cause=ROOT_CAUSE,
    comment=CLOSURE_COMMENT,
    assign_to_user=ASSIGN_TO_USER,
    tags=TAGS
)

Outputs

Output	Description
`CLOSURE_STATUS`	Success/failure status of the closure

Common Closure Patterns

Scenario	Reason	Typical Root Cause
False Positive	`NOT_MALICIOUS`	"Legit action", "Normal behavior"
Duplicate	`NOT_MALICIOUS`	"Similar case is already under investigation"
Benign True Positive	`NOT_MALICIOUS`	"Legit action"
Confirmed Threat (remediated)	`MALICIOUS`	Varies by threat type
Unable to determine	`INCONCLUSIVE`	"Insufficient data"

Get Valid Root Causes

If unsure of valid root cause values:

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.
