What is slkcli CLAUDE.md?

Project-specific instructions for slkcli, a macOS command-line tool for using Slack without installing a bot. They explain the main files, how to add commands, and how to test and publish changes.

Adding slkcli commands, updating its API or command routing, changing help and documentation, running tests, and preparing a package release.

They give a coding agent the project’s structure and release steps, reducing guesswork when changing the Slack CLI.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00527	$0.00527
Opus 5.5	$0.00211	$0.00211
Sonnet 5.5	$0.00105	$0.00105
Haiku 4.5	$0.00053	$0.00053

Security

Grade A, and why

slkcli CLAUDE.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 2mo 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.

What it actually says

CLAUDE.md — Quick Reference for Claude Code / Codex

What is slk?

Slack CLI for macOS. Auto-auth from Slack desktop app (session cookies, no bot install). Zero dependencies.

Key Files

src/commands.js — All command logic. Add new commands here.
src/api.js — slackApi() and slackPaginate(). Add POST endpoints to writeMethods array.
src/auth.js — Keychain + LevelDB credential extraction. Rarely needs changes.
src/drafts.js — Draft commands (create/list/drop).
bin/slk.js — CLI entry point. Command routing + help text.

Adding a Feature

Add function in src/commands.js (export async)
If new API needs POST → add to writeMethods in src/api.js
Add case + alias in bin/slk.js switch block
Add to HELP string in bin/slk.js
Update README.md (commands table, examples, flags if any)
Update SKILL.md (commands list)
npm version patch --no-git-tag-version
git add -A && git commit -m "feat: ..." && git push
echo "//registry.npmjs.org/:_authToken=${NPM_PUBLISH_TOKEN}" > .npmrc && npm publish && rm .npmrc
cp SKILL.md ~/moltbot/skills/slk/SKILL.md

Testing

node bin/slk.js <command>   # Direct run
slk <command>               # If globally linked

Patterns

Use getUsers() for user ID → name resolution (cached)
Use resolveChannel(nameOrId) for channel name/ID handling
Use formatTs(ts) for Slack timestamp → human date
Errors: console.error() + process.exit(1)
Output: console.log() with emoji prefixes

Auth

Session-based (xoxc- token + xoxd- cookie). Auto-extracted from Slack desktop app on macOS. Cache: ~/.local/slk/token-cache.json. Delete to force re-extract.

npm Publish Token

NPM_PUBLISH_TOKEN env var from ~/.local/keys/env.sh. Use .npmrc trick (create before publish, delete after).

Changes

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.
