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.

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 | $0.00067 | $0.00417 |
| Opus 5 | $0.00034 | $0.00209 |
| Sonnet 5 | $0.00013 | $0.00083 |
| Haiku 4.5 | $0.00007 | $0.00042 |
Grade A, and why
session-health-probe 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 13d 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
session-health-probe
This skill loads full instructions on activation. Read INSTRUCTIONS.md before proceeding.
Boundary (why this is the 5th health skill, not a merge)
This skill owns ONE axis no other health skill covers: dynamic RUNTIME liveness of the daemon and its live sessions, right now. It is deterministic and zero-LLM.
| Skill | Axis | When |
|---|---|---|
| session-health-probe (this) | runtime daemon + live-session liveness | continuous / 15-min job / on demand |
| s_loops-health | static self-cognition (memory, knowledge, evolution, governance) | periodic |
| s_health-check | post-build assertion of critical assumptions | after a build |
| s_chat-brain-check | frontend chat-experience contract | after a chat change |
| s_system-health | desktop CPU/RAM worst-offenders report | on demand |
If the question is "is the running system alive and are its sessions progressing?" → this skill. Anything static, post-build, or frontend → not this.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

session-health-probe is a skill published in the GitHub repository xg-gh-25/SwarmAI (44 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 417 once invoked, about $0.0003 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.

audit-config
Audit Antigravity project configuration and documentation for drift, staleness, and broken references. Use when user asks for 'config audit', 'docs audit', 'check setup', 'audit configs', 'review CLAUDE.md or GEMINI.md files', or at session start when audit cadence is exceeded.
ios-simulator
Verify and debug native, React Native, Expo, or Flutter apps on an iOS Simulator with agent-device. Use when an agent needs to launch an app, inspect its live UI, tap, type, scroll, validate a code change, collect failure evidence, or reproduce a workflow on an iPhone or iPad Simulator.
gsd-ns-review
Route to the appropriate quality / review skill based on the user's intent. gsd-code-review-fix was absorbed by gsd-code-review --fix in #2790.
ccc
This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the…

A health-diagnosis workflow for servers, computers, virtual machines, and containers on Linux, macOS, or Windows.
forensics
Post-mortem a failed GSD auto-mode run. Traces symptom to root cause via .gsd/ activity, journal, metrics, and lock artifacts, producing a filing-ready bug report with file:line refs and a fix suggestion. Use when asked to "forensics", "post-mortem", "why did auto-mode fail", "trace the stuck loop", "debug the crash"…
