todoist-cli: Instructions file for Codex

AGENTS.md

todoist-cli AGENTS.md is an instructions file for Codex, OpenCode from Doist/todoist-cli. It costs 1,329 tokens per session, scanned B, original, MIT.

A project guide for a TypeScript command-line program that manages Todoist, a task and to-do service. It documents the project structure, build commands, tests, and development rules.

In plain words
What is it for?
Use it when building, type-checking, linting, testing, or running the Todoist command-line tool, including its commands and flags.
Why use it?
It gives coding agents the commands and conventions needed to change the program correctly and check that the changes work.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is Doist/todoist-cli's own configuration. It tells Codex and OpenCode how to work on todoist-cli itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything todoist-cli configures →

Token cost

What 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.

Security

Grade B, and why

todoist-cli AGENTS.md 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 today.

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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Todoist CLI

For repo structure, where things live, and shared utilities, read CODEBASE.md first. This file covers the rules; CODEBASE.md is the map.

TypeScript CLI for Todoist. Binary name: td.

Build & Run

npm run build       # compile TypeScript (uses tsconfig.build.json, excludes tests)
npm run dev         # watch mode (uses tsconfig.build.json)
npm run type-check  # type check source + tests (uses tsconfig.json)
npm run check       # lint + format check
npm run fix         # auto-fix lint + format
npm test            # run tests

Two-tsconfig setup: tsconfig.json includes both source and test files — used by type-check and IDEs. tsconfig.build.json extends it but excludes colocated *.test.ts files plus src/test-support/ — used by build and dev to keep test-only code out of dist/.

Run the CLI directly (no linking needed):

node dist/index.js --help          # show commands
node dist/index.js today           # run 'today' command
node dist/index.js <command> ...   # run any command

Use this to verify changes work before committing.

Rules when changing code

  • Named flag aliases: where commands accept positional args for context (project, task, workspace), named flags (--project, --task, --workspace) are also accepted. Error if both positional and flag are provided.
  • Implicit view subcommand edge case: td project <ref> defaults to td project view <ref>. If a project/task name matches a subcommand name (e.g., "list"), the subcommand wins — users must use td project view list.
  • API response shape: client returns { results: T[], nextCursor? } — always destructure.
  • Priority mapping: CLI uses "p1"–"p4" strings; API uses 4=p1 (highest), 1=p4 (lowest). Use parsePriority from src/lib/task-list.ts, never hand-roll.
  • Errors: throw CliError(code, message, hints?) from src/lib/errors.ts for anything user-facing. The global parseAsync().catch in src/index.ts renders it correctly in JSON and pretty modes. The same handler also matches BaseCliError (re-exported from src/lib/errors.ts) so errors thrown by @doist/cli-core helpers route through the same formatter.

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.
