daimon-briefing 0.21.0

Dream-briefing for AI coding agents: writes a cognitive checkpoint at session end and shows a 'while you were away' briefing at session start. Self-contained, stdlib-only.

Daimon

Your AI coding agent forgets everything between sessions. Daimon writes a small cognitive checkpoint when a session ends, then renders a "while you were away" briefing when the next one starts — so the agent resumes from a faithful record of where you left off instead of a confident guess. Everything runs locally: per-project JSON checkpoints plus a derived SQLite index, no server, no external memory backend.

Every briefing item carries a trust class. ✓ verbatim items are pinned to an exact quote from the transcript and are never reworded. ~ inferred items are the agent's own conclusions and are allowed to evolve. Items carried from older sessions are tagged [carried]. Knowing which memories are quotes and which are guesses is the whole point.

Install

pip install daimon-briefing
# or, as an isolated tool:
uv tool install daimon-briefing

Add the [pretty] extra for rich tables and panels in status/brief (plain text works without it):

uv tool install 'daimon-briefing[pretty]'

The installed command is daimon. Requires Python 3.10+, stdlib-only at runtime.

Connect an LLM (one time)

Writing a checkpoint needs an LLM endpoint. If the claude CLI is on your PATH you are zero-config — daimon configure prints ✓ ready and you are done. Otherwise point it at any OpenAI-compatible endpoint:

daimon configure --backend litellm \
  --base-url https://generativelanguage.googleapis.com/v1beta/openai \
  --api-key <YOUR-KEY> --model gemini-2.5-flash

daimon configure --test    # send one tiny prompt and confirm the backend works

Or point it at a headless LLM CLI you already have installed:

daimon configure --backend command --command "mycli -p"

Some CLIs don't read the prompt from stdin — the Devin CLI takes it as a flag pointing at a file. --input controls how the prompt reaches the command (stdin default, arg appends it as the final argument, file:<flag> writes it to a tempfile and passes <flag> <path>):

daimon configure --backend command --command "devin -p" --input "file:--prompt-file"

Config lives in ~/.daimon/env (hooks run with the host's inherited environment, not your shell profile). Kill switch: DAIMON_DISABLE=1.

Hook up your host

Claude Code (plugin — recommended):

/plugin marketplace add Daily-Nerd/daimon
/plugin install daimon@daimon

The plugin registers the SessionStart/SessionEnd hooks itself.

Windsurf (and other hosts that ship packaged hooks):

daimon hooks install windsurf    # copies the hook script + prints the registration snippet
daimon hooks list                # hosts with packaged hook scripts

Codex and other hosts use the manual hook installer from a repository clone — see the GitHub docs.

Then end a session → a checkpoint is written; start the next → the briefing appears.

Quickstart without a host

The CLI also works on any plain-text or markdown transcript, no host required:

daimon serialize path/to/transcript.md   # transcript → checkpoint
daimon brief                             # render the "while you were away" briefing
daimon status                            # did the last checkpoint get written?

Teach your agent the protocol

Hooks capture your sessions; the skill teaches the agent on the other side to read the briefing at session start and treat verbatim items as immutable quotes:

daimon skill install claude    # also: codex, windsurf, cursor, gemini
daimon skill list              # which scopes each host supports

Commands

Command	What it does
daimon brief	Render the "while you were away" briefing from the latest checkpoint
daimon status	Checkpoint presence/age + last capture outcome; reports failures honestly
daimon recall <terms>	Full-text search over your whole checkpoint history
daimon resolve <item>	Mark a checkpoint item resolved so it stops carrying forward
daimon reverify <item>	Evidence-gated reopen of a resolved item
daimon heal [--force]	Re-serialize the most recent failed session, if it can be done safely; --force ignores a prior retry marker to re-heal a retry-exhausted session
daimon stats	Local usage + capture aggregates (nothing is transmitted)
daimon configure	Detect/repair the LLM backend
daimon hooks install <host>	Install packaged host hook scripts
daimon skill install <host>	Install the agent skill for a host

Run daimon --help or daimon <command> --help for the full surface, including code anchors (daimon anchor) and opt-in team memory (daimon team).
