+## Usage Cap Pricing Enforcement
+
+Standard edition can enforce AI budget caps before billable provider dispatch. API-key providers use OpenRouter `/models` pricing as the catalog source, with optional tenant/provider/model overrides in the dashboard.
+
+Excluded provider classes:
+- `chatgpt_oauth`, `claude_cli`, and `bailian` are treated as subscription/non-API pricing in round one.
+- local/no-key subprocess providers such as `acp` and `ollama` are skipped unless a future feature explicitly enables pricing for them.
+
+Runtime flow:
+1. Resolve the stored provider by name and skip non-billable provider classes.
+2. Load matching policies for tenant, agent, provider, provider type, and model.
+3. Resolve custom pricing override first, then OpenRouter catalog pricing when a matching policy has a cost ceiling. Native provider model IDs are mapped to OpenRouter prefixes for common providers such as OpenAI, Anthropic, and Gemini.
+4. Reserve estimated tokens and cost atomically before each dispatch attempt.
+5. Reconcile reserved counters after the provider returns usage or after a failed call.
+
+Token-only policies do not require catalog pricing. Model fallback routes reserve against the actual candidate provider/model before each attempt. Cached input is separated from uncached input for OpenAI-compatible usage accounting. Partial stream failures keep the estimate, or actual provider usage when available, instead of clearing billed output to zero. Internal LLM calls for memory flush, compaction, media reading tools (`read_image`, `read_document`, `read_audio`, `read_video`), and subagents use the same preflight/reconcile path.
+
+The legacy agent-level `budget_monthly_cents` field is treated as a generated monthly agent USD cap. Existing values are backfilled during migration, and later agent budget edits update or remove the generated cap policy.
+
+Supported price units: input, output, cache read, cache write, reasoning, request, image, and web search.

+### Credentialed CLI keyword allowlist
+
+`config.tools.commandKeywordAllowlist` lets operators allow specific product or security vocabulary inside selected credentialed CLI content arguments without disabling `deny_args`.
+
+Example:
+
+```json
+{
+  "tools": {
+    "commandKeywordAllowlist": [
+      {
+        "id": "github-content",
+        "command": "gh",
+        "subcommands": ["issue create", "issue edit", "pr create", "pr comment"],
+        "args": ["--body", "--title"],
+        "argPositions": [],
+        "keywords": ["secret", "secrets", "token", "credential"],
+        "reason": "Allow security vocabulary in GitHub issue and PR prose"
+      }
+    ]
+  }
+}
+```
+
+The rule above allows `gh issue create --body "secret rotation notes"` but still blocks command paths like `gh secret set TOKEN`. `argPositions` are 0-based after the matched subcommand. The scanner evaluates command arguments only; it does not read the contents of files passed through arguments such as `--body-file`.

+## Usage Cap Storage
+
+Usage cap enforcement is Standard/PostgreSQL-only in round one. The `UsageCapStore` is wired on the PostgreSQL store factory and left nil in SQLite/Lite builds.
+
+Tables:
+- `usage_pricing_catalog`: OpenRouter model catalog prices, raw upstream model payload, sync time.
+- `usage_pricing_overrides`: tenant/provider/model override prices for custom billing assumptions.
+- `usage_cap_policies`: cap definitions scoped by tenant, agent, provider, provider type, model, `window_key`, and `source`.
+- `usage_cap_counters`: current window used and reserved token/cost counters.
+- `usage_cap_reservations`: preflight reservations keyed by LLM call attempt.
+- `usage_cap_events`: allow/block/reconcile/skip audit events.
+
+Reservation updates are atomic: counters are updated only when `used + reserved + estimate` remains below configured token and cost ceilings.
+Reservation keys are idempotent per policy, so a retry using the same key does not double-increment reserved counters.
+Policy `agent_id` references must belong to the same tenant as the policy. Policy and pricing override `provider_id` references may belong to the same tenant or the master tenant for default provider fallback, but not another non-master tenant.
+Catalog and override price fields are nullable decimal strings with non-negative validation in the store layer and database checks.
+Pricing resolution checks exact override/catalog model IDs first, then provider-derived OpenRouter aliases for native unprefixed model IDs.
+
+Agent `budget_monthly_cents` values are bridged into `usage_cap_policies` with `source = 'agent_budget_monthly_cents'`, an agent scope, `window_key = 'month'`, and `max_cost_micros = budget_monthly_cents * 10000`. Updating or clearing the agent budget keeps that generated policy in sync; manual cap policies continue to use `source = 'manual'`.
+
+Migration versions:
+
+- PostgreSQL: `000070_usage_caps_pricing`, `000071_usage_cap_policies`, `000072_agent_budget_usage_cap_bridge`.
+- SQLite: no schema change; feature is not active in Lite.

 ## 3. Session Caching
 
 The session store uses an in-memory write-behind cache to minimize database I/O during the agent tool loop. All reads and writes happen in memory; data is flushed to the persistent backend only when `Save()` is called at the end of a run.

+## 9.5. Explicit Slash Skill Commands
+
+Users can bypass implicit skill matching by starting a prompt with a slash command:
+
+| Pattern | Behavior |
+|---------|----------|
+| `/<slug> prompt` | Activates the skill by slug and treats `prompt` as the skill input |
+| `/use <slug-or-name> prompt` | Activates the skill by slug or display name |
+| `/list-skills` | Shows available skills for the current agent context |
+| `/help <slug-or-name>` | Shows description and usage guidance for one skill |
+
+Slash detection runs during prompt construction after request context is scoped and before the skills section is built. A matched skill narrows the per-request `SkillFilter` to that skill and injects the full `SKILL.md` instructions into the system prompt for the current turn only. Normal matching remains unchanged for messages that do not start with the configured prefix, path-like strings such as `/home/user/file`, or unresolved commands without suggestions.
+
+Tenant settings live in `system_configs`:
+
+| Key | Default | Behavior |
+|-----|---------|----------|
+| `skills.slash_commands.enabled` | `true` | Enable slash command detection |
+| `skills.slash_commands.suggest_not_found` | `true` | Suggest similar skills for unknown commands |

+
+- `POST /v1/browser/cookies/sync`, `GET /v1/browser/cookies`, and `DELETE /v1/browser/cookies` require operator auth.
+- Sync fails when the request context has no user or no agent.
+- Store unique key is `(tenant_id, user_id, agent_id, domain, path, name)`.
+- Cookie values are encrypted at rest and never returned by list responses.
+- Browser runtime applies cookies only to matching domain/path for the same tenant, user, and agent scope.
+- Extension asks for active-site host permission and sends only checked cookies.
+
+## Main Risks
+
+| Risk | Mitigation |
+|------|------------|
+| Cross-user cookie leak | Store and browser scope include `tenant_id`, `user_id`, and `agent_id`. |
+| Client spoofs user | API ignores user fields in JSON body; user comes from auth context. |
+| Plaintext persistence | Cookie store fails closed when encryption key is missing. |
+| Oversized cookie payload | API caps body size, cookie count, and per-cookie value size. |
+| Overbroad extension access | Extension requests host permission for the current origin before reading cookies. |
+| Accidental value exposure | List endpoint returns metadata only. Logs never include cookie values. |
+
+## Operational Notes
+
+- Set `GOCLAW_ENCRYPTION_KEY` before enabling cookie sync.
+- Revoke synced cookies with `DELETE /v1/browser/cookies?agent_id=<agent>&domain=<domain>`.
+- Restart the gateway after changing browser launch settings that affect manager startup.

+### Automatic Beta Deploy From `dev`
+
+Pushing or merging into `dev` runs `.github/workflows/dev-beta-release.yaml`.

+# Google Workspace CLI Integration
+
+GoClaw supports Google Workspace CLI through the `gws` binary from `@googleworkspace/cli`.
+
+## Runtime availability
+
+- Published `full` image: `gws` is preinstalled.
+- Published `latest` image: Python is available, but Node/npm and `gws` are not preinstalled.
+- Published `base` image: Python and Node/npm are not preinstalled.
+- Custom Node-enabled builds: set `ENABLE_NODE=true`, then install `npm:@googleworkspace/cli` from the Packages page or `/v1/packages/install`.
+
+`gws` requires Node.js 18+ when installed through npm.
+
+## SecureCLI setup
+
+Create a SecureCLI credential from the `gws` preset. Provide at least one usable auth source:
+
+- `GOOGLE_WORKSPACE_CLI_CREDENTIALS_FILE`: exported `gws` credentials or an OAuth credentials JSON file path.
+- `GOOGLE_WORKSPACE_CLI_TOKEN`: pre-obtained OAuth access token.
+- `GOOGLE_WORKSPACE_CLI_CLIENT_ID` and `GOOGLE_WORKSPACE_CLI_CLIENT_SECRET`: optional OAuth client values for external auth flows.
+
+The preset blocks these interactive or credential-exporting commands:
+
+- `gws auth setup`
+- `gws auth login`
+- `gws auth export`
+- `gws auth logout`
+
+Run those flows outside agent execution, then store the resulting token or credentials file path in SecureCLI.
+
+## Agent command patterns
+
+Use `--params` for query parameters and `--json` for request bodies. Prefer read-only commands unless an admin has explicitly approved writes.
+
+Drive:
+
+```sh
+gws drive files list --params '{"pageSize": 10}'
+```
+
+Gmail:
+
+```sh
+gws gmail users messages list --params '{"userId": "me", "maxResults": 10}'
+```
+
+Calendar:
+
+```sh
+gws calendar events list --params '{"calendarId": "primary", "maxResults": 10}'
+```
+
+Pagination:
+
+```sh
+gws drive files list --params '{"pageSize": 100}' --page-all
+```
+
+Schema inspection:
+
+```sh
+gws schema drive.files.list
+```
+
+## Validation
+
+Without credentials, local validation can only prove packaging and credential injection:
+
+```sh
+gws --help
+gws drive files list --help
+```
+
+With credentials available, run these smoke tests from a SecureCLI-enabled agent or equivalent runtime:
+
+```sh
+gws drive files list --params '{"pageSize": 1}'
+gws gmail users messages list --params '{"userId": "me", "maxResults": 1}'
+gws calendar events list --params '{"calendarId": "primary", "maxResults": 1}'
+```
+
+Do not mark live Google Workspace validation complete unless all three authenticated commands return successful JSON.
+
+## Limitations
+
+- Google Workspace auth and scopes are controlled by the configured Google account, OAuth app, token, or credentials file.
+- Domain-wide delegation and account impersonation are not represented by a GoClaw preset env var. Configure those in Google Workspace and the credential file if needed.
+- Write commands can modify Workspace data. Keep the default preset read-oriented, and create a separate reviewed SecureCLI config for approved write workflows.

 ---
 
+## 2026-05-24
+
+### Google Workspace CLI runtime integration
+
+**Features**
+
+- Added `gws` as a preinstalled Google Workspace CLI in the full runtime image.
+- Added a SecureCLI `gws` preset with encrypted credential injection fields and guardrails for interactive auth/export commands.
+- Documented Drive, Gmail, and Calendar command patterns plus live credential smoke-test requirements.
+
+**Tests**
+
+- Added runtime binary discovery, SecureCLI preset, deny-pattern, and Dockerfile contract coverage for Google Workspace CLI.
+
+### Slash skill commands
+
+**Features**
+
+- Added explicit slash skill activation for `/<slug>`, `/use <slug-or-name>`, `/list-skills`, and `/help <slug-or-name>`.
+- Added tenant settings for slash command enablement, similar-skill suggestions, partial matching, and custom prefix.
+
+**Tests**
+
+- Added backend coverage for parser false positives, exact/partial skill resolution, suggestions, help/list commands, and config overlays.
+
+### Configurable skill upload limits
+
+**Features**
+
+- Added configurable skill ZIP upload limits with config/env, SKILL.md frontmatter, and tenant system setting support.
+- Added dashboard settings and dynamic upload validation so the Web UI follows the tenant limit instead of hardcoding 20MB.
+
+**Tests**
+
+- Added backend coverage for limit precedence, clamping, oversized rejection, and frontend coverage for parameterized upload validation.
+
+### CLI environment variable visibility
+
+**Features**
+
+- Added `sensitive` and `value` kinds for secure CLI environment variables across binary defaults, agent grant overrides, and user overrides.
+- Plain value entries are visible to authorized admins for operational config review, while sensitive entries remain masked and replace-only.
+
+**Fixes**
+
+- Stopped per-user credential reads from returning legacy sensitive env values raw.
+- Kept legacy `{"KEY":"value"}` env blobs backward-compatible by treating them as sensitive.
+
+**Tests**
+
+- Added backend regression coverage for env kind parsing, sanitized API responses, runtime flattening, and invalid kind rejection.
+- Verified Web UI build after adding env-kind controls and warnings.
+
+### Command keyword allowlist
+
+**Features**
+
+- Added scoped credentialed CLI keyword allowlist config for content arguments and positional arguments, with runtime reload and web config editing.
+
+**Fixes**
+
+- Kept credentialed CLI `deny_args` active for command paths such as `gh secret set` while allowing approved GitHub issue/PR prose to mention security vocabulary.
+- Added security audit logging for real allowlisted pass-throughs without logging full argument values.
+
+**Tests**
+
+- Added regression coverage for scoped keyword masking, disabled rules, unsafe positional rules, config reload, and race-safe policy snapshots.
+
+### Browser cookie sync and config UI
+
+**Features**
+
+- Added scoped browser cookie sync API, encrypted cookie store, browser runtime cookie application, dashboard browser settings, and a selected-cookie Chrome extension prototype.
+
+### Cron SecureCLI credential context
+
+**Fixes**
+
+- Fixed cron-triggered agent turns so credentialed CLI lookups preserve the explicit tenant user credential identity captured when the cron job is created.
+- Kept cron `user_id` ownership unchanged for group-scoped list/remove behavior while storing credential lookup identity separately in cron payload metadata.
+
+**Tests**
+
+- Added regression coverage for cron payload credential metadata, legacy payload compatibility, cron scheduler context injection, and SQLite cron persistence parity.
+
+---
+
+## 2026-05-22
+
+### Usage Cap budget controls
+
+**Features**
+
+- Added Standard/PostgreSQL usage caps for AI budget control by hour, day, week, or month.
+- Caps support token and USD cost ceilings at tenant, agent, provider, provider type, and model scopes.
+- Added OpenRouter catalog sync plus tenant/provider/model pricing overrides for input, output, cache read/write, reasoning, request, image, and web search units.
+- Enforced caps in agent, fallback model, subagent, memory flush, compaction, and media reading tools (`read_image`, `read_document`, `read_audio`, `read_video`) with preflight reservation and post-call reconciliation.
+- Added non-negative validation for catalog and override pricing fields.
+- Added OpenRouter alias resolution for native model IDs, cached-input accounting normalization, and partial-stream failure reconciliation.
+- Bridged legacy `budget_monthly_cents` into generated monthly agent USD cap policies, including migration backfill and save-time sync.
+- Added web dashboard controls on Usage and Provider detail pages.
+- Added Usage page editing for manual cap policies, including enable/disable, scope clearing, and token/USD limit clearing while keeping generated agent-budget caps read-only.
+- Added usage-cap decision metadata to LLM spans, including allow/skip/block reason, policy IDs, estimates, actuals, and reconcile status.
+
+**Tests**
+
+- Added pricing and cap service coverage.
+- Verified Go builds, SQLite build compatibility, full Go test suite, integration race suite, and Web UI production build.
+
+### Messaging debounce hardening
+
+**Features**
+
+- Added per-agent inbound debounce override via `other_config.inbound_debounce_ms`; unset inherits the global gateway setting.
+- Added Web Chat debounce for rapid text-only `chat.send` calls using `gateway.inbound_debounce_ms`.
+- Clarified shared inbound debounce behavior in docs and Web UI config help text.
+
+**Fixes**
+
+- Fixed inbound debounce semantics so `gateway.inbound_debounce_ms=0` means no debounce and positive values set the wait window.
+- Fixed Slack `debounce_delay: 0` so it disables per-thread batching instead of falling back to the default.
+
+**Tests**
+
+- Added regression coverage for channel inbound debounce, Web Chat debounce, media/cancel bypass handling, and Slack debounce config defaults.
+
+### CLI P6 backend API unblock
+
+**Features**
+
+- Added HTTP session branch and history follow endpoints for automation clients.
+- Added read-only channel writer permission testing.
+- Added split activity-log and runtime-log aggregate endpoints.
+
+**Tests**
+
+- Added focused HTTP, store, and runtime log coverage for branch/follow, writer test, activity aggregate, and LogTee ring aggregation.
+
+### CI/CD: zuey beta deploy
+
+**Features**
+
+- Added automatic zuey VPS deployment to the `Dev CI and Beta Release` workflow after beta prerelease assets are published.
+- The deploy job triggers the protected gateway upgrade endpoint with the generated `vX.Y.Z-beta.N` tag, waits for upgrade status, and verifies public `/health`.
+- Beta prereleases now upload `CHECKSUMS.sha256` alongside binary assets.
+
+**Fixes**
+
+- Updated the host release-upgrade script to support beta asset filenames with a leading `v`.
+- Added checksum fallback to GitHub release asset SHA256 digests when beta releases do not publish `CHECKSUMS.sha256`.
+- Detached gateway-triggered upgrades into a transient `systemd-run` unit so stopping `goclaw` during deploy no longer kills the upgrade job.
+- Allowed stale upgrade `running` status records to be superseded after timeout and made the zuey deploy wait loop tolerate transient 502s during restart.
+
+**Tests**
+
+- Added regression coverage for stale gateway upgrade status recovery.

+# GoClaw Selected Cookie Sync Extension
+
+Chrome MV3 extension for explicit selected-cookie sync into GoClaw browser sessions.
+
+Security model:
+- No automatic background sync.
+- Requests host permission only for the active tab origin.
+- Requests gateway-origin permission before sending the selected cookies.
+- Sends only checked cookies.
+- Sends `userId` and `agentId`; the gateway derives tenant scope from auth.
+- Stores extension settings in `chrome.storage.local`.

+//
+//  1. Group chats: UserID → "group:<channel>:<chatID>" composite (or
+//     "guild:<guildID>:user:<senderID>" for Discord) so multiple users in
+//     the same group share conversation memory and session state.
+//  2. DM with merged contact: UserID → tenant_user UUID after sender has
+//     been merged via ContactCollector.ResolveTenantUserID. Enables
+//     per-user features cross-channel for the same human, but breaks
+//     credential lookups keyed by external user id.
+//
+// Both rewrites are correct for *memory and tenant-user resolution*, but
+// wrong for resources scoped per-actor:
+//
+//   - MCP credentials are minted per-user by channel provisioners and stored
+//     with user_id = SenderID. Looking them up by the rewritten UserID always
+//     misses the row.
+//   - RBAC grants and audit attribution must reflect the real actor, not
+//     the rewritten container — otherwise every action in a group or after
+//     contact-merge looks identical to the policy engine.
+//
+// For Bitrix24 channel, where the provisioner always keys by SenderID
+// regardless of DM/group/merge state, we MUST always prefer SenderID.
+// Without the channelType discriminator, DMs with merged contacts hit the
+// "return userID" branch and silently lose MCP creds.
+//
+// Other channels (Telegram, Slack, Discord, Zalo) currently do not

+// file adds a lazy, best-effort enrichment path so the Contacts page can
+// show real names instead of "—" placeholders.
+//
+// Design choices:
+//   - Lazy + per-process cache: first sight of a user → 1 user.get RPC;
+//     every subsequent message from the same user is a cache hit. Bitrix
+//     profile data rarely changes, so a 1-hour TTL is plenty.
+//   - Negative caching (5min) absorbs Open Channel customer IDs and any
+//     other user.get failure mode. Without it, a webhook burst from an
+//     untrackable sender would trigger N pointless RPC calls.
+//   - Best-effort: any failure is logged at Debug and swallowed —
+//     EnsureContact still runs with empty fields, which is the exact
+//     pre-enrichment behavior. No regression path.
+//   - Skip enrichment entirely when Client()/Portal are not yet ready
+//     (before Start() completes) — otherwise a race on startup could call
+//     Call() against a nil-bound client and panic.
+//
+// Scope requirement: the Bitrix app's OAuth scope must include `user` for
+// user.get to succeed. If it doesn't, the RPC returns INSUFFICIENT_SCOPE
+// and we fall back to empty names (and log the reason once for the
+// operator). Document this in the UI's permissions note so admins know
