What it does
Metrickit is an agent skill from dpearson2699/swift-ios-skills. Use when collecting or analyzing production iOS or iPadOS performance telemetry with MetricKit, including iOS 27 MetricManager async metric or diagnostic reports, hang or crash triage, custom signposts, extended launch measurement, durable export, or iOS 26 MXMetricManager compatibility.
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/metrickit-patterns.md`).
It sits in Mobile, covering iOS development. It works with iOS and Xcode. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Analyzing production iOS
- IPadOS performance telemetry with MetricKit
- Including iOS 27 MetricManager async metric
- Diagnostic reports
Example prompts
- “/metrickit”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Encode the complete MetricReport or DiagnosticReport with JSONEncoder.
- Atomically enqueue the bytes in an app-owned durable outbox.
- Record report type, schema version, app version, and a stable deduplication key.
- Acknowledge local processing only after the enqueue succeeds.
- Upload later with retry, backoff, batching, and retention limits.
- Mark the outbox item uploaded only after the server accepts it.
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
sosumi.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Metrickit loads about 3.6k tokens when it runs, and up to ~6.8k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 1,262 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,262 words (~3,609 tokens).
“Use MetricKit for low-overhead production telemetry that complements local Instruments and Xcode Organizer analysis. On iOS and iPadOS 27, prefer the Swift-first MetricManager report sequences. Keep MXMetricManager only in an explicit iOS 26 compatibility branch.”
