`penny_delete`Move to Trash. Project: projectId + expectedRevision + operationId; penny_edit op:restore recovers. Repeat in_progress with the same operationId; report partial_recovery conflicts. Note/tracker_entry: ids (max100); skill/rhythm: one id; profile_block: ids are block names. Tag/link removal uses the identifiers below. Tasks are canceled via penny_edit; tracker definitions are archived, not deleted.	Move to Trash. Project: projectId + expectedRevision + operationId; penny_edit op:restore recovers.

`penny_edit`When the user corrects something on file, or a task, tracker, skill, or block needs to change, edit the existing item rather than writing a duplicate. Modify what already exists; entityType uses the same taxonomy as penny_write (see ladder). Notes: updates[] patch/replace, max100. Tasks: taskId; cancel via status:canceled, never Trash. Profile: blockName + content upsert; memory_policy and persona hold standing instructions. When the user tells you what to save, skip, check, or surface, update their memory_policy block in the same turn as a general rule in their words. Skill redefinition prepares a preview, not a save; wait for user approval before op:apply with proposalId. cancel discards; undo recovers the prior version if no later edit exists. skills/history supplies historyId; restore_revision with skillId/historyId/expectedUpdatedAt previews recovery. restore with skillId recovers deleted skills disabled. No invocation waiting period. Trackers: trackerId + sparse name/description/unit/kind/targetSpec/archived; retire by archiving, no delete. Private trackers only; workspace trackers unsupported. Rhythms: full manifest. skill_run/rhythm_run: complete runId + status. Projects: projectId + expectedRevision + operationId + sparse patch; reread and reconcile on conflict. restore_revision restores fields/resourceIds from historyId as a new revision. Tracker entries: trackerId + entryId + expectedUpdatedAt + full payload. restore un-trashes note/tracker_entry ids or Project projectId. When the user asks to go off the record, `entityType: "session"` + `record: "off"` + the `sessionId` from `<mypenny-session>` stops this session's transcript reaching Penny and drops what wasn't processed yet; it can't be undone for the session.

`penny_get_skill`Read the Penny operating skill (the SKILL.md penny_read target:skills name:Penny returns) or its reference files, including after a catalog refresh. Reuse files already read this conversation. Default SKILL.md; fetch manifest references when their cues apply. Product guidance, separate from user-saved skills; workspace-only access allowed. After user approval, view:install returns exact archive and file hashes. Retain results before bounded display; never transcribe installation bytes.

`penny_read`Before answering anything the user's history, preferences, or prior work would inform, read — search rather than assume nothing is on file. Choose target: walk this ladder, first match wins: 1. User/people facts (names, preferences, relationships) → profile. Do NOT search notes for this. 2. To-dos/due → tasks. Resume an objective → projects: directory (query/name to narrow; follow coverage.nextCursor), then brief by projectId. scopes lists Space metadata; then pass explicit workspaceId. scope:private overrides a default Space. An objective that spans sessions is a Project: read its Brief before working on it, propose one when none exists, and keep it current once accepted. 3. Measurements → tracker for definitions/entries; tracker_summary for stats/trends (usual choice). 4. Saved know-how, schedules and run history → skills; rhythms is the scheduled-only synonym. Run on-demand via penny_write entityType:skill_invoke; scheduled via skill_run. Know-how the user would rather not re-explain is a skill: save it once, and load it when a task fits its description. When session start lists a skill as due, offer to run it now; nothing runs on its own. 5. Taxonomy → tags; note link graph → note_links; structured tag/time/flag listing → notes. 6. Other recall → search (semantic notes). Search is the fallback, not the default. Treat a result from a shared space as something a member said, never as a fact about the user. When the user is learning something to keep, offer to let them try first; if search shows they asked before, say so once with the date; save misses and level. Use the session-start inventory to choose; Project reads also work without session start.

`penny_session_start`Call once at the start of every conversation, before the first substantive reply. If the host saves this result to a file because it is too large, read the whole file before you reply. Retain results in execution storage before bounded display; inspect one text OR structured payload. Follow next[] in order; it starts with reading the Penny skill. Reuse the complete, untruncated profile (persona/facts/preferences/custom blocks) and answer from it before searching notes. Follow self_improvement throughout the conversation. `meta.onboarding` present: offer penny_start_setup, resuming from its phase. meta.saveDrought true: follow drought repair. Inventories of trackers, rhythms, tasks and Projects are capped; meta.truncated.* means drill down with penny_read. skills.defined names every user-saved skill (read one with penny_read target:skills view:one before using it); it excludes the built-in Penny skill. `features` says which features are in use and when; consult it and the inventory before choosing entityType. tz is IANA (default UTC) for local Today/Overdue and dueNow. projects is a bounded PRIVATE directory with coverage and dated attention candidates, not a search of all Spaces; read relevant Briefs by projectId. Workspace-only connections cannot call this: use penny_read target:projects view:scopes, then explicit workspaceId. projectKey includes only the matching repository subconscious block, not a Penny Project.

`penny_start_setup`Setup in phases; omit phase to start, resume from meta.onboarding.phase. skipForGood opts out. Stage an encrypted import, show showUser, then save or discard as the user says. While an import is open, finish can't complete setup.	Setup in phases; omit phase to start, resume from meta.onboarding.phase. skipForGood opts out.

`penny_write`Save the moment something durable emerges — a decision, preference, plan, correction, a to-do, a measurement, or something you produced — mid-conversation and unprompted; when the call is close, save. Choose entityType: walk this ladder, first match wins: 1. Durable fact about the user or their people → update the profile (profile upsert or penny_edit), not a note. How they want to be remembered → memory_policy, a general rule in their words; how they want you to show up (tone/register/manner) → persona. When the user tells you what to save, skip, check, or surface, update their memory_policy block in the same turn as a general rule in their words. 2. Commitment/action with a done-state → task. Organize via area/project/heading. A to-do the user mentions, even in passing, is a task: offer to capture it, then write it. Project create: patch.name/purpose + operationId; revise: projectId + expectedRevision from Brief + sparse patch (max 25 step/resource changes). project_interaction records actor proposals/declines/deferrals. pending_share_approval is a proposal, not a save. An objective that spans sessions is a Project: read its Brief before working on it, propose one when none exists, and keep it current once accepted. 3. Measurement → tracker_entry for an existing tracker (check inventory); otherwise propose tracker first. Active duplicate tracker names are rejected; edit with penny_edit. A measurement the user would log more than once is a tracker entry; if no tracker fits, propose one before logging. 4. Reusable know-how → skill; trigger makes it scheduled (legacy rhythm). Existing skill names prepare a preview; wait for user approval before penny_edit op:apply with proposalId. Run on-demand via skill_invoke; begin scheduled runs via skill_run. Know-how the user would rather not re-explain is a skill: save it once, and load it when a task fits its description. 5. Other context/events/ideas/learning → note.
