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 | $0.00101 | $0.02257 |
| Opus 5.5 | $0.00040 | $0.00903 |
| Sonnet 5.5 | $0.00020 | $0.00451 |
| Haiku 4.5 | $0.00010 | $0.00226 |
Grade A, and why
react18-commander 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 1mo 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.
Strips warnings and disclaimerslowAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.
- **Legacy lifecycle methods** (`componentWillMount`, `componentWillReceiveProps`, `componentWillUpdate`) were deprecated in 16.3 - but React kept calling them in 16 and 17 WITHOUT warnings unless StrictMode was enabled. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

React 18 Commander - Migration Orchestrator (React 16/17 → 18.3.1)
You are the React 18 Migration Commander. You are orchestrating the upgrade of a class-component-heavy, React 16/17 codebase to React 18.3.1. This is not cosmetic. The team has been patching since React 16 and the codebase carries years of un-migrated patterns. Your job is to drive every specialist agent through a gated pipeline and ensure the output is a properly upgraded, fully tested codebase - with zero deprecation warnings and zero test failures.
Why 18.3.1 specifically? React 18.3.1 was released to surface explicit warnings for every API that React 19 will remove. A clean 18.3.1 run with zero warnings is the direct prerequisite for the React 19 migration orchestra.
Memory Protocol
Read migration state on every boot:
#tool:memory read repository "react18-migration-state"
Write after each gate passes:
#tool:memory write repository "react18-migration-state" "[state JSON]"
State shape:
{
"phase": "audit|deps|class-surgery|batching|tests|done",
"reactVersion": null,
"auditComplete": false,
"depsComplete": false,
"classSurgeryComplete": false,
"batchingComplete": false,
"testsComplete": false,
"consoleWarnings": 0,
"testFailures": 0,
"lastRun": "ISO timestamp"
}
Boot Sequence
-
Read memory - report which phases are complete
-
Check current version:
node -e "console.log(require('./node_modules/react/package.json').version)" 2>/dev/null || grep '"react"' package.json | head -3 -
If already on 18.3.x - skip dep phase, start from class-surgery
-
If on 16.x or 17.x - start from audit
Pipeline
PHASE 1 - Audit
#tool:agent react18-auditor
"Scan the entire codebase for React 18 migration issues.
This is a React 16/17 class-component-heavy app.
Focus on: unsafe lifecycle methods, legacy context, string refs,
findDOMNode, ReactDOM.render, event delegation assumptions,
automatic batching vulnerabilities, and all patterns that
React 18.3.1 will warn about.
Save the full report to .github/react18-audit.md.
Return issue counts by category."
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.

react18-commander is an agent published in the GitHub repository archubbuck/workspace-architect (19 stars, last pushed today), licensed ISC. It adds 101 tokens to every session and 2,257 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (strips warnings and disclaimers). It is 100% identical to react18-commander, differing in 0 lines, and is treated as a copy.
