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.
npx agentmods add agents/nylas/cli/readmegit clone --depth 1 https://github.com/nylas/cliWhat 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 | $0.00000 | $0.01074 |
| Opus 5 | $0.00000 | $0.00537 |
| Sonnet 5 | $0.00000 | $0.00215 |
| Haiku 4.5 | $0.00000 | $0.00107 |
Grade A, and why
README 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Parallelization Guide
Use parallel agents to explore or review the 745-file codebase without exhausting context.
When to Use Parallel Agents
| Task | Agents | Why |
|---|---|---|
| Full codebase exploration | 4 | One per major directory |
| Feature search | 3 | Search cli, adapters, tui simultaneously |
| Multi-file PR review | 4 | Review different files in parallel |
| Test coverage analysis | 4 | Analyze different packages |
Invocation Patterns
# Full exploration (3 agents)
"Explore using 3 parallel agents:
- Agent 1: internal/cli/
- Agent 2: internal/adapters/
- Agent 3: internal/domain/ + ports/ + tui/"
# Feature search (3 agents)
"Find all email-related code using 3 agents across cli, adapters, tui"
# PR review (4 agents)
"Review these 8 files using 4 parallel code-reviewer agents"
Directory Parallelization Value
| Directory | Files | Parallel Value |
|---|---|---|
internal/cli/ |
268 | HIGH |
internal/adapters/ |
158 | HIGH |
internal/tui/ |
77 | MEDIUM |
internal/domain/ |
21 | LOW (shared) |
Safe vs Unsafe
Safe to parallelize:
- Explore, review, search across different directories
- Multiple code-reviewers on different files
- Multiple codebase-explorers
Avoid parallelizing:
- Write to same file
- Modify
domain/orports/nylas.goin parallel - Run integration tests in parallel (rate limiting)
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.

README is an agent published in the GitHub repository nylas/cli (68 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,074 tokens. 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.

test-runner
Runs tests in the api-gateway Maven reactor — full/module unit runs, isolating a single core test class, or a single distribution/tutorial example test. Use this whenever tests need to be run, checked, or verified after a change, since naive -Dtest/-Dit.test invocations silently run (or skip) the wrong thing in this…

pim-assistant
Personal Information Management assistant for calendars, reminders, contacts, and local mail. Use this agent when: User mentions scheduling, appointments, meetings, events, or calendar User mentions reminders, tasks, todos, "remind me", or "don't forget" User asks about contacts, people, email addresses, phone numbers…
debug-integracao
Especialista em diagnóstico de problemas em integrações com a API da Tray. Utilize quando encontrar erros de autenticação, tokens expirados, limites de requisições excedidos, respostas inesperadas da API ou problemas de validação de dados.
