Forget for good

crbro_forget
DestructiveIdempotent

Delete data from disk after quarantining a copy so credentials, personal data, or whole neurons no longer exist, retaining a restorable backup.

Instructions

Write, destructive: remove from disk after a quarantine copy (backup returned). Stage 3 of the lifecycle: something must not exist on disk at all — a credential, personal data, a whole neuron → crbro_forget; for knowledge that merely stopped being true use crbro_revise, which keeps the history. One mode per call. facts: delete entries of a neuron (facts, decisions, patterns, preferences, errors, debts, the map) by id or exact text. entire: delete the whole neuron and its synapses — call it without confirm_token first: the dry run reports what would happen and returns confirm_token. Show the user, get agreement, call again with the token; a stale token is refused. restore: bring back the newest quarantine copy. merge_into: union a neuron into another, rewire synapses, delete the source. session: delete one day's log, search index included (quarantine keeps the text). entire and merge_into refuse a shared neuron — crbro_share unshare first. A removed credential must still be rotated.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
factsNoMode facts: the ids crbro_inspect and crbro_recall show, or the exact text, of facts, decisions, patterns, preferences, errors or debts; the exact full text of the map removes the map. Deleted for good after a quarantine copy; decision/pattern removals travel to shared spaces like errors and debts.
entireNoMode entire: delete the whole neuron and its synapses. Without confirm_token it is a dry run — { neuron_id, dry_run:true, counts, shared_in, confirm_token }. Refused (no token) while the neuron is shared: crbro_share unshare first.
neuronNoNeuron id or name the mode acts on. Required for every mode except session. restore needs the exact neuron id.
restoreNoMode restore: bring back the newest quarantine copy of `neuron` (exact id). If the neuron exists again, the copy is merged into it (merged_into_existing:true, moved counts). The quarantine file stays, so restore is repeatable.
sessionNoMode session: session id ("session_2026-09-03" or "2026-09-03") whose log is deleted after a quarantine copy. `neuron` is not needed.
merge_intoNoMode merge_into: target neuron id or name. Everything of `neuron` is unioned into it, synapses rewired, then `neuron` is deleted (quarantined first). Refused while `neuron` is shared.
confirm_tokenNoOnly with entire:true — the token from the dry run. Derived from the neuron's counts, so it goes stale (and is refused) when the neuron changed in between.

TDQS

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds substantial context beyond the annotations: the quarantine copy that precedes deletion, the backup/restore path, the dry-run return shape and confirm_token staleness semantics, that session deletion also clears the search index, and that restore is repeatable because the quarantine file persists. These are behaviors an agent cannot infer from destructiveHint/idempotentHint alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the essential frame (write, destructive, quarantine) before the mode catalog, and the mode:semantics pattern is easy to scan. However, the single dense paragraph runs long and the parenthetical fact-type list is heavier than needed, costing a point for density.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description compensates by describing return payloads (dry run { neuron_id, dry_run:true, counts, shared_in, confirm_token }, merged_into_existing) and every prerequisite and refusal condition. For a seven-parameter destructive multi-mode tool, this is complete enough to invoke correctly without trial and error.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter's meaning is already documented in the schema; the description mostly restates the mode semantics. The one genuine addition is the 'one mode per call' constraint, which is not encoded in the schema. Baseline 3 is appropriate where the schema carries the parameter burden.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb and resource plus the operational metaphor ('remove from disk after a quarantine copy'), then enumerates six distinct modes with concrete objects (facts, neuron, synapses, day's log). It explicitly distinguishes itself from crbro_revise by the permanence criterion ('something must not exist on disk at all' vs 'knowledge that merely stopped being true').

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit routing rule to the sibling (crbro_forget vs crbro_revise), states the one-mode-per-call constraint, describes the two-step dry-run/confirm_token workflow with 'show the user, get agreement', and names prerequisites ('entire and merge_into refuse a shared neuron — crbro_share unshare first'; stale token refused).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
