What is the-controller-setting-credentials?

A secure way to put an API key, password, or other secret into a project's .env file. The value is entered in a masked app window and is not shown in terminal output or the conversation.

Use it when configuring a project that needs credentials for an external service, such as an API.

It prevents sensitive values from appearing in command history, logs, agent replies, or other visible output.

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	$0.00038	$0.00288
Opus 5.5	$0.00015	$0.00115
Sonnet 5.5	$0.00008	$0.00058
Haiku 4.5	$0.00004	$0.00029

Security

Grade A, and why

the-controller-setting-credentials 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.

What it actually says

Setting Credentials

Overview

Use controller-cli to write secrets to .env files securely. The secret value is entered through a modal in The Controller UI — it never appears in the terminal, agent output, or conversation context.

Usage

controller-cli env set --project <project> --key <ENV_KEY>

The CLI connects to The Controller app via Unix socket, opens a secure input modal, and writes the value to the project's .env file. Output is redacted — only the key name and status are printed.

Finding the project name

Check the THE_CONTROLLER_SESSION_ID env var if running inside a Controller session
Otherwise, use the working directory name (e.g. my-app for /path/to/my-app)
The project must already be known to The Controller

What happens

CLI sends request to The Controller app
A secure modal opens in the app UI
User enters the secret value (masked input)
Value is written to the project's .env file
CLI prints redacted confirmation (e.g. created OPENAI_API_KEY for my-app)

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.
