 - **AKM Skill** — Claude automatically uses the `akm` CLI when you ask about stash assets
-- **Agentic hooks** — lifecycle hooks that install `akm`, set `defaults.agent` to `claude` (and add a matching `profiles.agent.claude` entry) in `~/.config/akm/config.json` when no agent default is configured, auto-curate stash matches into every user prompt, auto-record feedback when assets are used (skipping proposed-quality drafts plus `lesson:*` and `secret:*` refs), surface pending-proposal counts in the SessionStart header, and harvest session memories at stop/compact time

 | **SessionStart** | Verifies `akm` on PATH satisfies the required `^0.8.0` range (override via `AKM_PACKAGE_REF`). When `akm` is missing or out of range, the hook does **not** install anything — it writes a clear stderr banner pointing the user at the `/akm-setup` slash command (the explicit-consent install path) and emits a degraded SessionStart context telling the agent `akm` tooling is unavailable for this session. When `akm` is healthy, the hook sets `defaults.agent` to `claude` (and ensures `profiles.agent.claude` exists) in `~/.config/akm/config.json` when no agent default is configured (legacy `agent.default` is auto-migrated on load), surfaces the configured agent CLI plus any pending-proposal count in the injected header, warms the stash index in the background, injects `akm hints`, and runs a scoped `akm curate --run <session_id>` so Claude gets relevant stash context before the first user message. Human users should run `akm setup` manually when interactive setup is needed. |
 | **UserPromptSubmit** | Runs `akm curate "<prompt>" --run <session_id>` and injects the top matches as `additionalContext` so Claude sees relevant stash assets before answering. Short prompts (under `AKM_CURATE_MIN_CHARS` chars, default 16) are skipped. Also records `remember`/`memory` intents to the session buffer. |
-| **UserPromptExpansion** | Logs expanded `/akm-*` slash-command usage, injects a short reminder when a mutating memory/proposal command is expanded without explicit confirmation language, and takes a fresh proposal-prep checkpoint before `/akm-improve`, `/akm-evolve`, or `/akm-propose` when the local session buffer has unflushed evidence. |
+| **UserPromptExpansion** | Logs expanded `/akm-*` slash-command usage and injects a short reminder when a mutating memory/proposal command is expanded without explicit confirmation language. |
 | **PreToolUse** (Agent) | Resolves invalid Claude Code subagent model aliases (e.g. `balanced`, `gpt-4o`) to the four valid aliases (`sonnet`, `opus`, `haiku`, `inherit`) so dispatch is never rejected upstream. |
 | **PreToolUse** (Read / Write / Edit / Glob / Grep) | Observes asset refs in tool input for memory-event capture. Never blocks. |
 | **PostToolUse** (Bash, success) | Logs `akm` Bash invocations, harvests any `type:name` asset refs (including `lesson:*`) from command+output, and calls `akm feedback <ref> --positive` so successful usage boosts ranking. Skips `memory:*`, `env:*`, `secret:*`, `lesson:*`, and any ref the indexer reports as `quality:"proposed"`. |
 | **PostToolUseFailure** (Bash) | Same as above but records `--negative` feedback with the failure note. |
-| **PostToolBatch** | Records grouped tool-batch observations as structured events and appends a short batch summary to the local session buffer for later checkpoint extraction. |
+| **PostToolBatch** | Records grouped tool-batch observations as structured events and appends a short batch summary to the local session buffer for later candidate extraction. |
 | **SubagentStart** | Injects concise AKM subagent context, including the detected role, task preview, and any active workflow summary. |
-| **Stop** / **SubagentStop** | Flushes the per-session buffer into a `memory:claude-session-YYYYMMDD-<sid>` memory so every meaningful session contributes durable context for future searches. Session memories now include explicit paths to the local state, buffer, event/candidate logs, and optional harness log plus higher-value evidence aggregates so follow-on improve agents can inspect the full artifacts directly. The hook also follows that flush with `akm index` so upstream inference/graph passes run immediately. Set `AKM_INDEX_ON_SESSION_END=0` to opt out (e.g. low-power dev machines, CI runners). |
-| **TaskCreated** / **TaskCompleted** | Records task lifecycle events, appends task summaries to the local session buffer, and lets completed-task summaries feed candidate extraction through the normal checkpoint/session flush path. |
-| **PreCompact** | Same memory capture before Claude Code compacts the transcript, with the same default-on post-flush `akm index` run (set `AKM_INDEX_ON_SESSION_END=0` to skip). |
+| **TaskCreated** / **TaskCompleted** | Records task lifecycle events, appends task summaries to the local session buffer, and lets completed-task summaries feed candidate extraction (surfaces suggestions for `/akm-memory-promote`) using the buffer as source-path evidence. |
 | **PostCompact** | Records the compacted summary as a structured event and buffers a short post-compaction note for later recall. |
-| **SessionEnd** | Reuses the session-final memory capture path so Claude can flush the final checkpoint even when `Stop` is not the last lifecycle event observed. |
+| **SessionEnd** | Runs `akm index` so upstream inference/graph passes pick up the session's changes (set `AKM_INDEX_ON_SESSION_END=0` to skip), and separately fires event-driven `akm extract` for the just-ended session so durable insights reach the proposal queue without waiting for the periodic `akm improve` extract pass. |

@@ -237,7 +235,6 @@ Notes:
 | `AKM_PACKAGE_REF` | `akm-cli@^0.8.0` | Override the npm/bun package spec displayed in the SessionStart consent banner and used by `/akm-setup` (for example, to pin a compatible AKM build in CI). The plugin never installs this automatically — it is only quoted in the banner. |
 | `AKM_LOCAL_BUILD_CLI` | _(unset)_ | Optional absolute path to a locally built AKM CLI entrypoint such as `/abs/path/to/akm/dist/cli.js`. When set, the Claude hook runs that build through Bun before checking `akm` on PATH. Useful when developing `akm` and `akm-plugin` side by side. |
 | `AKM_AUTO_FEEDBACK` | `1` | Set to `0` to disable automatic `akm feedback` on tool success/failure. |
-| `AKM_AUTO_MEMORY` | `1` | Set to `0` to disable automatic session-summary memories. |
 | `AKM_INDEX_ON_SESSION_END` | `1` | Set to `0` to skip the post-session `akm index` run (e.g. low-power dev machines or CI runners). |
 | `AKM_CURATE_LIMIT` | `5` | Max curated results injected into context per prompt. |
 | `AKM_CURATE_MIN_CHARS` | `16` | Minimum prompt length before curation runs. |
