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 | $0.00015 | $0.00824 |
| Opus 5 | $0.00008 | $0.00412 |
| Sonnet 5 | $0.00003 | $0.00165 |
| Haiku 4.5 | $0.00002 | $0.00082 |
Grade A, and why
squad-conventions 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 7d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
Squad has zero runtime dependencies. Everything uses Node.js built-ins (`fs`, `path`, `os`, `child_process`). Do not add packages to `dependencies` in `package.json`. This is a hard constraint, not a preference. This is a copy
100% identical to squad-conventions — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context
These conventions apply to all work on the Squad CLI tool (create-squad). Squad is a zero-dependency Node.js package that adds AI agent teams to any project. Understanding these patterns is essential before modifying any Squad source code.
Patterns
Zero Dependencies
Squad has zero runtime dependencies. Everything uses Node.js built-ins (fs, path, os, child_process). Do not add packages to dependencies in package.json. This is a hard constraint, not a preference.
Node.js Built-in Test Runner
Tests use node:test and node:assert/strict — no test frameworks. Run with npm test. Test files live in test/. The test command is node --test test/.
Error Handling — fatal() Pattern
All user-facing errors use the fatal(msg) function which prints a red ✗ prefix and exits with code 1. Never throw unhandled exceptions or print raw stack traces. The global uncaughtException handler calls fatal() as a safety net.
ANSI Color Constants
Colors are defined as constants at the top of index.js: GREEN, RED, DIM, BOLD, RESET. Use these constants — do not inline ANSI escape codes.
File Structure
.squad/— Team state (user-owned, never overwritten by upgrades).squad/templates/— Template files copied fromtemplates/(Squad-owned, overwritten on upgrade).github/agents/squad.agent.md— Coordinator prompt (Squad-owned, overwritten on upgrade)templates/— Source templates shipped with the npm package.squad/skills/— Team skills in SKILL.md format (user-owned).squad/decisions/inbox/— Drop-box for parallel decision writes
Windows Compatibility
Always use path.join() for file paths — never hardcode / or \ separators. Squad must work on Windows, macOS, and Linux. All tests must pass on all platforms.
Init Idempotency
The init flow uses a skip-if-exists pattern: if a file or directory already exists, skip it and report "already exists." Never overwrite user state during init. The upgrade flow overwrites only Squad-owned files.
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.

squad-conventions is a skill published in the GitHub repository dotnet/maui-labs (213 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 824 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). It is 100% identical to squad-conventions, differing in 0 lines, and is treated as a copy.

Optimizes a React Native app by profiling first to find real bottlenecks, then sweeping for mechanical issues. Entry-point for all performance work. Use when the app feels slow, user asks to optimize, fix re-renders, reduce jank, or improve startup. Delegates to argent-react-native-profiler for measurement.

argent-tv-interact
Control and inspect TV apps via argent — Apple TV (tvOS), Android TV (leanback), and Amazon Fire TV (Vega). Boot the target, read focus, navigate with the D-pad remote, type, screenshot, and on Vega debug the JS runtime (evaluate, console logs, network inspector). Use when a task targets a TV (runtimeKind "tv", or…
