What is toggle-hooks?

A command for turning Fellow's automatic knowledge-base context enrichment on or off, or checking its current status. Context enrichment adds relevant stored information to coding requests.

Use it to check the hook status, enable automatic enrichment, or disable it.

It lets you decide whether every request is enriched automatically or passes through unchanged unless you explicitly use the Fellow command.

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	$0.00009	$0.00647
Opus 5	$0.00005	$0.00324
Sonnet 5	$0.00002	$0.00129
Haiku 4.5	$0.00001	$0.00065

Security

Grade A, and why

toggle-hooks 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Toggle Fellow Hooks

Enable or disable automatic context enrichment hooks.

Objective

Control whether Fellow automatically intercepts and enriches coding requests:

When enabled: Coding requests are automatically enriched with semantic knowledge from the knowledge base
When disabled: All requests pass through unchanged (use /fellow command for explicit enrichment)

Arguments

$ARGUMENTS (optional): The action to perform
- status - Show current hook status (default if no argument provided)
- on or enable - Enable automatic context enrichment
- off or disable - Disable automatic context enrichment

Implementation

CRITICAL: This is an EXECUTABLE command, not documentation. You MUST execute the Python tool, not display its contents.

Step 1: Execute the toggle_hooks.py tool

Run the following command to toggle the hooks:

python3 ${CLAUDE_PLUGIN_ROOT}/tools/toggle_hooks.py $ARGUMENTS

Important:

Replace $ARGUMENTS with the actual argument provided by the user (status/on/off)
If no argument provided, use "status" as default
The script will output status messages directly - do NOT add additional commentary
Simply show the output from the script to the user

Step 2: Display Output

The script will output appropriate messages:

For status: Shows whether hooks are enabled or disabled
For on: Confirms hooks have been enabled
For off: Confirms hooks have been disabled

Do NOT:

Display the Python script contents
Display bash script alternatives
Add extra explanations beyond the script output
Show implementation details

Examples

Check Status

/fellow:toggle-hooks status

Expected behavior: Execute python3 ${CLAUDE_PLUGIN_ROOT}/tools/toggle_hooks.py status and show its output

Enable Hooks

/fellow:toggle-hooks on

Expected behavior: Execute python3 ${CLAUDE_PLUGIN_ROOT}/tools/toggle_hooks.py on and show its output

Disable Hooks

/fellow:toggle-hooks off

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.
