Agent runtime (embedded p-mono), workspace contract, and session bootstrap
Agent Runtime π€
Reeve runs a single embedded agent runtime derived from p-mono.
Workspace (required)
Reeve uses a single agent workspace directory (agents.defaults.workspace) as the agentβs only working directory (cwd) for tools and context.
Recommended: use reeve setup to create ~/.reeve/reeve.json if missing and initialize the workspace files.
Full workspace layout + backup guide: Agent workspace
If agents.defaults.sandbox is enabled, non-main sessions can override this with
per-session workspaces under agents.defaults.sandbox.workspaceRoot (see
Gateway configuration).
Bootstrap files (injected)
Inside agents.defaults.workspace, Reeve expects these user-editable files:
AGENTS.mdβ operating instructions + βmemoryβSOUL.mdβ persona, boundaries, toneTOOLS.mdβ user-maintained tool notes (e.g.imsg,sag, conventions)BOOTSTRAP.mdβ one-time first-run ritual (deleted after completion)IDENTITY.mdβ agent name/vibe/emojiUSER.mdβ user profile + preferred address
On the first turn of a new session, Reeve injects the contents of these files directly into the agent context.
Blank files are skipped. Large files are trimmed and truncated with a marker so prompts stay lean (read the file for full content).
If a file is missing, Reeve injects a single βmissing fileβ marker line (and reeve setup will create a safe default template).
BOOTSTRAP.md is only created for a brand new workspace (no other bootstrap files present). If you delete it after completing the ritual, it should not be recreated on later restarts.
To disable bootstrap file creation entirely (for pre-seeded workspaces), set:
{ agent: { skipBootstrap: true } }Built-in tools
Core tools (read/exec/edit/write and related system tools) are always available,
subject to tool policy. apply_patch is optional and gated by
tools.exec.applyPatch. TOOLS.md does not control which tools exist; itβs
guidance for how you want them used.
Skills
Reeve loads skills from three locations (workspace wins on name conflict):
- Bundled (shipped with the install)
- Managed/local:
~/.reeve/skills - Workspace:
<workspace>/skills
Skills can be gated by config/env (see skills in Gateway configuration).
p-mono integration
Reeve reuses pieces of the p-mono codebase (models/tools), but session management, discovery, and tool wiring are Reeve-owned.
- No p-coding agent runtime.
- No
~/.pi/agentor<workspace>/.pisettings are consulted.
Sessions
Session transcripts are stored as JSONL at:
~/.reeve/agents/<agentId>/sessions/<SessionId>.jsonl
The session ID is stable and chosen by Reeve. Legacy Pi/Tau session folders are not read.
Steering while streaming
When queue mode is steer, inbound messages are injected into the current run.
The queue is checked after each tool call; if a queued message is present,
remaining tool calls from the current assistant message are skipped (error tool
results with "Skipped due to queued user message."), then the queued user
message is injected before the next assistant response.
When queue mode is followup or collect, inbound messages are held until the
current turn ends, then a new agent turn starts with the queued payloads. See
Queue for mode + debounce/cap behavior.
Block streaming sends completed assistant blocks as soon as they finish; it is
off by default (agents.defaults.blockStreamingDefault: "off").
Tune the boundary via agents.defaults.blockStreamingBreak (text_end vs message_end; defaults to text_end).
Control soft block chunking with agents.defaults.blockStreamingChunk (defaults to
800β1200 chars; prefers paragraph breaks, then newlines; sentences last).
Coalesce streamed chunks with agents.defaults.blockStreamingCoalesce to reduce
single-line spam (idle-based merging before send). Non-Telegram channels require
explicit *.blockStreaming: true to enable block replies.
Verbose tool summaries are emitted at tool start (no debounce); Control UI
streams tool output via agent events when available.
More details: Streaming + chunking.
Model refs
Model refs in config (for example agents.defaults.model and agents.defaults.models) are parsed by splitting on the first /.
- Use
provider/modelwhen configuring models. - If the model ID itself contains
/(OpenRouter-style), include the provider prefix (example:openrouter/moonshotai/kimi-k2). - If you omit the provider, Reeve treats the input as an alias or a model for the default provider (only works when there is no
/in the model ID).
Configuration (minimal)
At minimum, set:
agents.defaults.workspacechannels.whatsapp.allowFrom(strongly recommended)
