brief

One-shot lean context brief for injecting into a subagent prompt. brief is a stripped-down sibling of sibyl context: given a goal, it prints wake-layer markdown only, with no skill ceremony, no related-graph expansion, and no JSON envelope. Pipe or paste the output straight into a worker agent's prompt.

Synopsis

sibyl brief <goal> [options]

Arguments

Argument	Required	Description
goal	Yes	Subagent goal or task

Options

Option	Short	Default	Description
--intent	-i	build	Agent intent (see context)
--project	-p	(auto)	Project ID
--all	-a	false	Use all accessible projects
--budget		1500	Token budget for the rendered brief (100-8000)

Examples

# Lean brief for a worker agent
sibyl brief "implement the password reset endpoint"

# Bias toward debugging context with a smaller budget
sibyl brief "auth token refresh fails intermittently" --intent debug --budget 800

# Inject straight into a subagent prompt
PACK=$(sibyl brief "wire up OAuth2")

Notes

• brief always uses the wake layer with related-graph expansion off, so it is faster and leaner than context. Reach for context when you need a deeper pack, raw memories, a diary, or JSON.
• The project comes from --project, then the directory link, then the active context's default project (with a notice). With none of those the command stops and says how to scope it; --all reads every accessible project on purpose and labels the result.
