Lark CLI is a command-line tool for using Lark/Feishu services such as messaging, documents, spreadsheets, calendars, mail, tasks, and meetings. It is intended for people and AI agents that need to work with these business tools through terminal commands.

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 | $0.03126 | $0.03126 |
| Opus 5.5 | $0.01250 | $0.01250 |
| Sonnet 5.5 | $0.00625 | $0.00625 |
| Haiku 4.5 | $0.00313 | $0.00313 |
Grade A, and why
cli AGENTS.md 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 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.
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.

Purpose
lark-cli is the official Lark/Feishu CLI for humans and AI agents. Optimize
for predictable machine-readable behavior without making the human CLI worse.
Keep each PR focused on one goal: CLI UX, reliability, simpler explicit code, or a useful gate. Done means the correct implementation surface, preserved contracts unless a break was requested, and reported checks.
Public behavior, tests, lint, and CI define current contracts. Existing code is
evidence, but a legacy exception is not precedent; Proposal documents are
direction only. Do not mix unrelated cleanup, hand-edit generated files, weaken
gates, or broaden allowlists to make CI pass.
Implementation Discipline
Use this sequence for product behavior or enforcement changes:
- Establish the current contract and owner before choosing a solution. Trace the flow from the command or shortcut through runtime and internal owners to wire output; inspect affected callers and tests, then choose the surface below.
- Apply YAGNI to scope. Implement the behavior required now; do not add speculative modes, configuration, compatibility paths, extension points, or scaffolding.
- Reuse the project's existing machinery before creating a parallel path. Prefer the owning generic, runtime, or internal surface, then the Go standard library or an existing dependency, while preserving the contracts below.
- Fix the root cause at the narrowest cohesive boundary shared by affected callers. Keep command and domain policy at the caller unless there is a real cross-command invariant for an internal owner to enforce.
- Ship the smallest complete change: implementation, a revert-failing regression test for behavior or enforcement, and required contract or guidance updates.
Optimize for minimum owned complexity, not minimum diff or line count. A correct root-cause fix may touch the owner, callers, tests, and docs; a one-line workaround at the wrong layer is not simpler. Prefer deletion and boring explicit code, and avoid one-use abstractions or new dependencies for straightforward behavior.
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.

cli AGENTS.md is an instructions file published in the GitHub repository larksuite/cli (17,986 stars, last pushed yesterday), licensed MIT. It adds 3,126 tokens to every session, about $0.0125 per session on Opus 5.5. 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.
