neurata 1.8.0

Deposit raw, curate quietly, retrieve at the right moment.

The living knowledge layer for an agent's environment (CLI, IDE, framework). Companion to Conscio, which minds the agent itself; Neurata minds the agent's world: skills, tools, docs, decisions — catalogued, curated, retrievable.

Install

pip install neurata      # or: pipx install neurata

From source, for hacking on it:

git clone https://github.com/Neguiolidas/Neurata
python3 -m venv ~/.venvs/neurata
~/.venvs/neurata/bin/pip install -e ./Neurata
ln -sf ~/.venvs/neurata/bin/neurata ~/.local/bin/neurata   # if ~/.local/bin is on PATH

Zero runtime deps. The archive lives in ~/.neurata (override with NEURATA_HOME). neu is installed alongside neurata as a typing convenience — docs always use neurata.

Use

# deposit (stdin via '-', or positional text)
echo "raw content" | neurata deposit -
neurata deposit "raw content" --title "Note"
# agent, session and project come from the environment and from the repo
# you deposit in — nothing to pass by hand

# catalogue the inbox (mechanical, reversible — nothing is destroyed)
neurata tick

# query (deterministic lexical)
neurata query "term"
neurata query "term regime:curated"   # facet: what the archive owns
                                      # (regime:mirror = synced from a source)
neurata query "term class:procedural" # memory axis: how-to, as opposed to
                                      # class:episodic (a dated event) and
                                      # class:semantic (a fact)
neurata query "term agent:agente-exemplo"     # provenance: who deposited it
                                      # (agent:/session:/origin:/project:,
                                      #  curated only)
neurata query "term missing:agent"    # the gaps: curated grains with no agent
neurata query "term tag:osint"        # tags the SOURCE declared (v1.8 carries
                                      # them from yaml/skill/markdown into
                                      # the index — mirrors included)
neurata query "term --include-stale"  # tombstoned grains are excluded by
                                      # default; this flag brings them back
neurata expand <id>          # card → summary → full
neurata expand <id> --restore # bring the full body back from the archive

# shrink a grain's served body; the full is archived, never dropped
neurata compact <id>         # no-op unless it actually shrinks; refuses
                             # mirrors (the next tick would undo it)

# what the archive itself flags
neurata shelf --conflicts    # near-duplicates and id/slug collisions

# contradictions: "use X" vs "never use X" — same target, opposite
# polarity, detected deterministically at tick/reindex (no LLM)
neurata contradictions            # report: open pairs, resolved count
neurata contradictions --resolve  # apply the deterministic winner rule
neurata supersede <id> --by <id>  # or pick the winner yourself; the
                                  # loser is marked in its frontmatter
                                  # (`superseded_by`), never deleted
neurata query "term status:superseded"  # and search stops being blind:
                                        # cards carry `contradicts` and
                                        # superseded grains sink

# mirror an external source into the inbox (then `tick` catalogues it)
neurata harvest                        # default provider: claude-code skills
neurata harvest project                # THIS repo's instruction files:

                                       # instructions.md, .cursorrules and
                                       # .cursor/rules/*.mdc — found at the
                                       # git root of the cwd (override with

                                       # classed by its shape

Context bias (deterministic)

The search knows where you are — the same way the deposit does since v1.2. Grains from your current project, your current session, and recently touched grains get a modest, fully deterministic boost before the result is cut; no LLM, no embedding, no service.

neurata query "deploy"          # project from git root of the cwd
NEURATA_PROJECT=myrepo neurata query "deploy"   # explicit, zero cost
NEURATA_SESSION=$ID neurata query "deploy"      # session affinity

• NEURATA_PROJECT wins over the git probe (agents should set it); the git probe has a 0.5 s timeout and failure means "no bias", never an error.
• An explicit facet mutes its bias: project:X disables the project boost for that query — the facet is sovereign.
• Every JSON answer declares what it used: "context": {"project", "session", "source"} — a bias you cannot see is a bias you cannot trust. source is env, git, none, or disabled (bias switched off in config, so nothing was even looked at).
• All three knobs live in config.json under "context" (project_boost, session_boost, recency_weight, recency_tau_dias); zeroing one switches that hint off cleanly.
• The pre-cut recency hint and the shelf's recency are two different layers: the hint decides who enters the top-k, the shelf reorders inside it.

Automatic curation

tick catalogues whatever is in the inbox. Run it hourly via cron:

0 * * * * $HOME/.local/bin/neurata tick >> $HOME/.neurata/logs/cron-tick.log 2>&1

neurata doctor warns (last-tick) if the cron stops.

tick also absorbs edits: fix a grain's body in your editor and the next tick re-hashes it into the index, keeping its id, slug and provenance. Editing only the frontmatter (class:, type:, tags:) leaves the body unchanged, so the tick sees nothing to absorb — run neurata reindex after those.

Principles

• Grains sit on two independent axes. Regime — who owns the grain — is derived from the file's shape, never authored: a grain carrying a source_key is a mirror of some external source, everything else is curated. Class — what kind of memory it is — is declared in the frontmatter (class: episodic | semantic | procedural); a curated grain without one is episodic, because a deposit is a dated event. A mirror's class is written by the harvest from the file's shape — a skill or a rules file is procedural, prose and YAML are semantic — and a shape the adapter doesn't know declares nothing at all. Neither axis is ever guessed from the text, and neurata query "missing:class" lists the grains that predate the declaration.

• Files are the truth (a valid Obsidian vault); the index is a disposable cache.

• Deterministic retrieval first; LLMs only where explicitly wanted.

• Nothing is ever destroyed: archive + quarantine, never delete.

• Zero runtime dependencies. Python ≥ 3.10.

Status: v1.4.0, in daily use on a real vault. neurata doctor reports index health at any moment.
