A command that switches between Dev Work Mode and Knowledge Work Mode by updating a project setting. The setting is stored in a local Claude configuration file.

Use it to turn Knowledge Work Mode on or off and confirm the current working mode.

It avoids manually editing the mode setting and preserves other configuration values during a switch.

About the project

Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.

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.

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	$0.00014	$0.00684
Opus 5	$0.00007	$0.00342
Sonnet 5	$0.00003	$0.00137
Haiku 4.5	$0.00001	$0.00068

Security

Grade A, and why

km 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 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.

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.

Origin

This is a copy

91% identical to octo-km — 8 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.

Implementation Instructions

When this command is executed:

Parse the argument:
- No argument or "on" → target mode = Knowledge Work (knowledge_mode: true)
- "off" → target mode = Dev Work (knowledge_mode: false)
Check current mode via .claude/claude-octopus.local.md:
- Target is Dev Work AND file does NOT exist → user is already in Dev Work Mode (default). Do not create the file. Show confirmation only, then exit.
- File exists AND current knowledge_mode already equals the target → Do not rewrite the file. Show confirmation only, then exit.
- Otherwise → proceed to step 3 (real transition needed).
Switch modes (only when a real transition is required):
- Before writing, state one sentence: "Switching to Knowledge Work — creating .claude/claude-octopus.local.md (knowledge_mode: true)." (or the equivalent for Dev Work).
- If the file does not exist, create it with minimal frontmatter containing only the fields being set.
- If the file exists, update only the knowledge_mode field; preserve any other keys.
- Confirm with the target mode's emoji (🎓 / 🔧) and active personas.

Rule (v9.30+): Never create or rewrite .claude/claude-octopus.local.md when the user is already in the target mode. The v9.29 behavior over-executed — it wrote config for a state the user was already in, without explanation. Skip the Write tool entirely when there's nothing to change. See agents/principles/write-intent.md for the general principle.

Usage

/octo:km         # Switch to Knowledge Work mode (default action)
/octo:km on      # Switch to Knowledge Work mode (explicit)
/octo:km off     # Switch to Dev Work mode (same as /octo:dev)

Two Work Modes

Dev Work Mode 🔧 (default)

Best for: Building features, debugging code, implementing APIs
Personas: backend-architect, code-reviewer, debugger, test-automator

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.
