Config Manager Tool

The agent can read, update, validate, and restore its own configuration file.

Tool Name

manage_config

Actions

read

Returns the full config.toml content with sensitive fields redacted:

api_key = "***REDACTED***"
bot_token = "***REDACTED***"
password = "***REDACTED***"

get

Read a specific TOML key path:

action: "get"
key: "provider.models.primary"
# Returns: "gemini-3-flash-preview"

set

Update a specific key with a new value (TOML literal format):

action: "set"
key: "state.working_memory_cap"
value: "100"

Before writing:

1. Creates backup (3-deep ring rotation: .bak → .bak.1 → .bak.2)
2. Validates the new config (TOML syntax + full deserialization)
3. Sets file permissions to 0600 (owner-only) on Unix

restore

Rollback to the most recent backup file.

Backup Priority

1. config.toml.lastgood — proven working config
2. config.toml.bak — most recent backup
3. config.toml.bak.1
4. config.toml.bak.2
