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 | $0.00062 | $0.06712 |
| Opus 5 | $0.00031 | $0.03356 |
| Sonnet 5 | $0.00012 | $0.01342 |
| Haiku 4.5 | $0.00006 | $0.00671 |
Grade A, and why
axiom-push-notifications scanned grade A with 1 finding 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Push Notifications
Remote and local notification patterns for iOS. Covers permission flow, APNs registration, token management, payload design, actionable notifications, rich notifications with service extensions, communication notifications, Focus interaction, and Live Activity push transport.
When to Use This Skill
Use when you need to:
- ☑ Implementing remote (APNs) push notifications
- ☑ Requesting notification permissions
- ☑ Managing device tokens and server sync
- ☑ Adding actionable notifications with categories/actions
- ☑ Building rich notifications with service extensions
- ☑ Communication notifications with avatars (iOS 15+)
- ☑ Time Sensitive or Critical alerts
- ☑ Updating Live Activities via push (transport layer)
- ☑ Broadcast push for large audiences (iOS 18+)
- ☑ Local notification scheduling
Example Prompts
"How do I set up push notifications?" "When should I ask for notification permission?" "My push notifications aren't arriving" "How do I add buttons to notifications?" "How do I show images in push notifications?" "How do I send push updates to a Live Activity?" "What's the difference between APNs token and FCM token?" "How do I make notifications break through Focus mode?" "My notifications work in development but not production" "How do I handle notification taps to open a specific screen?"
Red Flags
Signs you're making this harder than it needs to be:
- ❌ Requesting permission on first launch before user understands value
- ❌ Caching device tokens locally instead of requesting fresh each launch
- ❌ Sending the same token to sandbox AND production APNs
- ❌ Using
content-available: 1without understanding silent push throttling (~2-3/hour) - ❌ Not implementing
serviceExtensionTimeWillExpirefallback - ❌ Force-unwrapping device token or assuming registration always succeeds
- ❌ Hardcoding APNs host instead of switching sandbox/production by environment
- ❌ Setting
apns-priority: 10for all notifications (drains battery, gets throttled) - ❌ Exceeding 4KB payload without realizing APNs silently rejects it
- ❌ Using FCM without disabling method swizzling when you have custom delegate handling
- ❌ Not handling foreground notification presentation (notifications silently dropped)
- ❌ Overusing Time Sensitive interruption level (erodes user trust, they'll disable all notifications)
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.

axiom-push-notifications is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 62 tokens to every session and 6,712 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

opensrc
Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for"…
inbound-email
Handle email arriving at a ServiceNow instance — inbound email action ordering and stop-processing, the real syseventinemailaction column names, and reading sysemail when a message created no record.
mcp-tool-discovery
Find and call tools on this ServiceNow MCP server — the two meta-tools it starts with, why a missing session id makes every other tool unreachable, which queries actually match, and which advertised tools are not on the server at all.

What actually happens when you call snowexecutescript — the Scripted REST endpoint Serac auto-deploys on first use, the scheduled-job fallback, what scheduledjobpending means, and how to get output back when the call comes home empty.
csdm-modeling
Pick the right ServiceNow service class under the Common Service Data Model — business service, service offering, application service, business application — and point the CMDB tools at it without creating the records CSDM tells customers to migrate away from.
cmdb-patterns
Create ServiceNow CIs and cmdbrelci relationships, walk upstream/downstream impact, detect orphan/stale CIs, and align discovered CIs with the proper sysclassname hierarchy.
