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 | $0.00061 | $0.07473 |
| Opus 5.5 | $0.00024 | $0.02989 |
| Sonnet 5.5 | $0.00012 | $0.01495 |
| Haiku 4.5 | $0.00006 | $0.00747 |
Grade B, and why
midnight-expert scanned grade B 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 2mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
Missing Docker permissions cause Docker commands to fail with permission denied. The resolution is to add the user to the docker group with `sudo usermod -aG docker $USER` and log out and back in. How it starts
The opening of the file, as written. The whole thing — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Midnight Expert
Midnight Expert Overview
Midnight Expert is the meta plugin for ecosystem diagnostics across all Midnight development tooling. It coordinates health checks, version compatibility verification, dependency scanning, and environment validation across the entire Midnight stack. When a developer encounters issues that span multiple components, Midnight Expert provides a unified diagnostic view that identifies root causes and recommends resolutions.
The meta plugin design means that Midnight Expert does not directly implement diagnostic logic. Instead, it orchestrates the diagnostic capabilities of each specialized plugin. It queries the proof server plugin for proof generation health, the indexer plugin for data pipeline health, the tooling plugin for development environment health, and other plugins for their respective domains.
Midnight Expert is activated through the doctor command which runs a full diagnostic sweep. The doctor command produces a summary report, a detailed JSON report, and actionable recommendations. It can be run interactively in the terminal or integrated into CI pipelines for automated health checks.
Version matrix management is a core responsibility. Midnight Expert maintains a comprehensive mapping of which versions of each component are compatible with each other. This matrix is consulted during health checks to detect version mismatches that could cause subtle runtime errors.
Network diagnostics verify that all required network endpoints are reachable. This includes the node JSON-RPC endpoint, the indexer GraphQL endpoint, the proof server HTTP endpoint, and any faucet endpoints. Each endpoint is tested for connectivity, response time, and health status.
Health Check System
The health check system runs a series of checks against each plugin and aggregates the results. Each check returns a status of healthy, degraded, or unhealthy, along with a human-readable message and diagnostic data. The system categorizes checks by severity so that critical issues that prevent development are highlighted while informational issues are noted but do not block the report.
What ships with it
3 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.

midnight-expert is a skill published in the GitHub repository mzf11125/midnight_agent_skills (5 stars, last pushed 4mo ago), licensed MIT. It adds 61 tokens to every session and 7,473 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
