Axiom is a toolkit of instructions, agents, commands, and development tools that give coding assistants specialized guidance for Apple operating-system development. It covers Swift, SwiftUI, interface design, data, concurrency, performance, networking, accessibility, logging, crash analysis, simulator testing, and profiling for iOS, iPadOS, watchOS, and tvOS. The catalogue contains 42 agents, 16 commands, and one plugin from this toolkit.
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 | $0.00018 | $0.00348 |
| Opus 5 | $0.00009 | $0.00174 |
| Sonnet 5 | $0.00004 | $0.00070 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
console 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 5d 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.
What it actually says
Capture Simulator Console
Captures iOS simulator console output using xclog, combining print/debugPrint (stdout/stderr) with os_log/Logger into structured JSON.
Steps
- Read
.axiom/preferences.yaml— if it exists and has asimulatorsection, use saveddevice,deviceUDID, andbundleId. If the file exists but is malformed, skip and fall back to discovery - If no saved preferences, run
xclog listto discover installed apps - Ask the user which app to capture (or use the saved/specified one)
- Run
xclog launch <bundle-id> --timeout 30s --max-lines 200 - Present the captured output, highlighting errors and faults
- If the device or bundle ID changed from saved preferences, save to
.axiom/preferences.yaml(seeaxiom-tools (skills/xclog-ref.md)skill for write instructions)
Usage Tips
- Use
--filter "error|warning"to focus on problems - Use
--subsystem <name>to filter by the app's logging subsystem - Use
--timeout 60sfor longer capture sessions - Pipe through
jq 'select(.level == "error")'to extract only errors - Use
--output /tmp/console.logto save for later analysis

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.

console is a command published in the GitHub repository CharlesWiltgen/Axiom (1,146 stars, last pushed 7d ago), licensed MIT. It adds 18 tokens to every session and 348 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
