MFA ServiceNow Skills

Execution blueprints for AI agents working with ServiceNow portals. Not documentation — these are pipelines with mandatory safety gates, sub-agent delegation hints, and exact tool calls.

Why Skills (vs raw tools)

	Tools Only	Skills + Tools
Safety	LLM decides (운빨)	Gates enforced (diff→preview→confirm→apply)
Tokens	Source dumps in context	Delegate to sub-agent, summary only
Accuracy	LLM guesses tool order	Verified pipeline
Recovery	Might forget	diff_local_component before push + server-side version history

Skill Metadata

context_cost: low|medium|high    # Token budget hint
safety_level: none|confirm|staged # Gate enforcement level
delegatable: true|false           # Can run in sub-agent
required_input: what user must provide
output: summary|report|diff|data|status|files|action|diagnosis

Dry-Run Preview (write tools, v1.8.22+)

All mutating tools (update_*, delete_*, add_*, remove_*, reorder_*) accept dry_run=True. When set, the tool issues only read-only Table/Aggregate API calls and returns a structured preview — no side effects. Shape:

{
  "dry_run": true,
  "operation": "update"|"delete"|...,
  "target": {"table": "...", "sys_id": "..."},
  "target_found": bool,
  "proposed_changes": {"field": {"before": x, "after": y}},  # update
  "no_op_fields": [...],                                      # update
  "dependencies": {"activities": N, "versions": N},           # delete
  "warnings": [...],
  "precision_notes": {"count_source": "table_api", ...}
}

Recommended flow for any write: dry_run=True → show diff → confirm=approve. Works under every auth type (basic/OAuth/API key/browser) — read-only APIs only.

Cross-Scope Dep Auto-Resolve (v1.8.21+)

download_app_sources(auto_resolve_deps=True) (default) scans downloaded sources and pulls referenced cross-scope records from global/other scopes:

Script Includes — new X(), gs.include('X'), new GlideAjax('X')
Widgets — <sp-widget id="X">, $sp.getWidget('X')
Angular Providers — $inject, angular.module(..., [...])
UI Macros — <g:macro> / <g2:macro> Jelly tags (excl. builtins)

Pulled records are saved into the same scope tree with is_dependency: true in _metadata.json. Business rules / client scripts / UI actions are not auto-resolved (table-bound, not referenced by name from code).

Skill Index

Kept deliberately lean: only general, cross-tool playbooks remain. Single-tool wrappers and feature-specific pipelines were dropped — tool descriptions and the tools' own built-in safety gates cover those. Enforcement lives in the tools, not in skills (skills are advisory; they can't be forced).
