+Agent tools can queue media files through `Result.Media`; the consumer converts
+those entries into `OutboundMessage.Media` and preserves file order, MIME type,
+filename, and optional captions.
+
+- `send_file` accepts either the legacy single `path` + optional `caption`, or

+  documents; audio groups only with audio. Voice-mode audio, singleton chunks,
+  oversized images sent as documents, and incompatible runs use the existing
+  ordered single-send fallback.
+- Discord already sends multiple files plus optional text in one message.

+### 3.5 Skill Self-Evolution
+
+Skill self-evolution tracks how each existing skill performs over time. It is
+separate from agent-level `skill_evolve`, which teaches agents when to create or
+patch reusable skills.
+
+**Runtime recording**
+
+- `use_skill` tool calls record tenant-scoped usage with status `succeeded` or
+  `failed`, duration, session key, run/trace ID, agent ID, and user scope.
+- Slash-command activation records a `started` event when `/<slug>` or
+  `/use <skill>` resolves to a skill.
+- Usage writes are internal only. v1 intentionally has no public
+  `POST /v1/skills/{id}/usage` endpoint, so clients cannot forge success rates.
+
+**Persistent tables**
+
+| Table | Purpose |
+|-------|---------|
+| `skill_evolution_settings` | Per-tenant, per-skill enabled flag and mode |
+| `skill_usage_metrics` | Runtime usage events and status counts |
+| `skill_improvement_suggestions` | Skill-scoped suggestions with evidence and draft patches |
+| `skill_versions` | Immutable applied-version records linked to changed files and suggestions |
+
+**HTTP and CLI controls**
+
+- HTTP: `GET/PATCH /v1/skills/{id}/evolution`,
+  `GET /v1/skills/{id}/metrics`,
+  `GET /v1/skills/{id}/activity`, and suggestion approve/reject/apply endpoints.
+- CLI: `goclaw skills evolve`, `goclaw skills metrics`,
+  `goclaw skills suggestions`, and `goclaw skills activity`.
+- Web UI: Skill detail has an `evolution` tab for settings, metrics,
+  suggestions, and admin-visible activity.
+
+**Guardrails**
+
+- Default mode is `suggest_only`; no automatic patching happens in v1.
+- Applying a suggestion to a custom skill copies the current skill directory to
+  the next version, validates the target path, runs the SKILL.md guard scanner
+  when needed, updates the active skill, records `skill_versions`, and writes an
+  activity log entry.
+- System/bundled skill mutation is refused by the apply path.
+- Viewer surfaces are sanitized. Failure evidence, draft patches, actor IDs,
+  and activity details require admin visibility.
+
+**Relationship to self-improving skills**
+
+This v1 is the control-plane foundation for self-improving skills: runtime usage
+events, evidence-backed suggestions, reference-file patches, version records,
+and approval/audit surfaces. It does not yet run a consolidation extractor that
+turns repeated corrections into learning notes or auto-applies user-scoped
+reference overlays. That higher-level learning loop belongs above this
+foundation and must keep scope separation, private-content filtering, evidence
+thresholds, and owner/admin approval policies explicit.

+### Multi-attachment outbound delivery (issue #172)
+
+**Changes**
+
+- Extended `send_file` with `attachments[]` so agents can queue multiple
+  existing workspace files in one tool call while preserving order and captions.
+- Added caption propagation from tool result media through agent media results
+  into outbound channel attachments.
+- Added Telegram media-group delivery for compatible batches with 2-10 item
+  chunks, plus ordered fallback for singleton, voice, oversized-image, or mixed
+  incompatible cases.
+- Added explicit channel batch capability metadata for Telegram, Discord, and
+  ordered fallback channels.
+
+**Tests**
+
+- Added batch `send_file` regressions for happy path, duplicate rejection, and
+  all-or-nothing delivered-state handling.
+- Added Telegram media-group chunking tests for compatible grouping, max-size
+  chunking, and non-groupable fallback.

+### Skill self-evolution metrics and upgrades (issue #161, issue #142 foundation)
+
+**Features**
+
+- Added per-skill self-evolution settings, usage metrics, suggestions, immutable
+  applied-version records, and activity logs.
+- Added trusted runtime usage recording for `use_skill` and slash skill
+  activations without exposing a public usage-write endpoint.
+- Added skill evolution HTTP, CLI, and Web UI surfaces for settings, metrics,
+  suggestions, approval/apply actions, and admin-visible activity.
+- Added the shared foundation needed by self-improving skills: usage evidence,
+  reference-file patches, versioned apply, and approval/audit surfaces. The
+  consolidation learning extractor and auto user-scoped overlays remain out of
+  this v1 scope.
+
+**Safety**
+
+- Blocked direct system skill mutation in the suggestion apply path.
+- Reused a shared target-path validator for skill companion/reference patches.
+- Sanitized failure evidence, draft patches, actor IDs, and activity details
+  away from non-admin surfaces.
+
+**Tests**
+
+- Added focused skill path validator coverage and deep-link coverage for the new
+  Web UI evolution tab.

+
+# Phase 1: Research and TDD Contracts
+
+## Overview
+
+Lock current behavior and expected batch semantics before implementation. Tests should fail until the new batch API and Telegram grouping helpers exist.
+
+## Requirements
+
+- Functional: agents can request multiple existing files in one call.
+- Functional: returned `Result.Media` preserves file order, filename, MIME type, and per-file captions when provided.
+- Functional: duplicate delivery guard rejects already queued files in the same run.
+- Non-functional: no file content reads in the tool path; only `stat` and path metadata.
+- Non-functional: keep single-file `send_file` behavior backward compatible.
+
+## Architecture
+
+`send_file` stays the existing tool name and grows an optional `attachments` array. The array entries mirror the current single-file fields: `path` and optional `caption`. If `attachments` is present, it is the source of truth; otherwise current `path` behavior remains.
+
+## Related Code Files
+
+- Modify: `internal/tools/send_file.go`
+- Modify: `internal/tools/send_file_test.go`
+- Modify: `internal/channels/capabilities.go`
+- Create: `internal/channels/telegram/send_media_group_test.go` if helper tests need a focused file.
+
+## Implementation Steps
+
+1. Add failing tests for `send_file` with `attachments: [{path, caption}, ...]`.
+2. Add failing tests for duplicate handling: one duplicate in a batch rejects before marking new paths.
+3. Add failing tests proving old `path` + `caption` still returns one media entry.
+4. Add Telegram helper tests for chunk sizing and type grouping without calling the network.
+5. Add Discord regression test coverage around multi-file `sendMediaMessage` if existing test hooks allow it without live API.
+
+## Success Criteria
+
+- [x] Tests describe batch tool contract and current single-file compatibility.
+- [x] Telegram grouping constraints are encoded in pure helper tests.
+- [x] No live channel credentials required.
+
+## Risk Assessment
+
+Main risk is over-scoping platform capability metadata. Keep tests focused on behavior needed by issue #172.

+
+# Phase 2: Tool API Batch Attachments
+
+## Overview
+
+Implement the backward-compatible tool API extension in `send_file`.
+
+## Requirements
+
+- Functional: `send_file({attachments:[...]})` queues multiple media files in one result.
+- Functional: path resolution, allow/deny guards, regular-file checks, MIME detection, and duplicate detection match single-file behavior.
+- Functional: optional captions are copied onto result media for downstream channel senders.
+- Non-functional: batch validation is all-or-nothing; do not mark any path delivered until every entry validates.
+
+## Architecture
+
+Refactor `SendFileTool.Execute` into small helpers:
+- Parse single vs batch arguments.
+- Resolve and validate each requested attachment.
+- Check duplicate state against `DeliveredMedia` and within the batch.
+- Build `[]bus.MediaFile`, then mark delivered after success.
+
+No new tool name unless tests show the model schema becomes unclear; existing `send_file` is the least disruptive contract.
+
+## Related Code Files
+
+- Modify: `internal/tools/send_file.go`
+- Modify: `internal/tools/send_file_test.go`
+- Modify: `internal/bus/types.go`
+- Modify: `internal/agent/loop_types.go`
+- Modify: `internal/agent/loop_tools.go`
+- Modify: `cmd/gateway_consumer.go`
+
+## Implementation Steps
+
+1. Extend `SendFileTool.Parameters()` with optional `attachments` array.
+2. Add caption support to `bus.MediaFile`, `agent.MediaResult`, and `appendMediaToOutbound` so tool-level captions reach channel senders.
+3. Implement parsing helpers with clear validation errors for missing path, non-array entries, duplicate paths, and denied paths.
+4. Keep existing single-file code path behavior and messages stable.
+5. Run `go test ./internal/tools -run 'TestSendFile|TestMessage|TestWriteFile|TestDeliveredMedia'`.
+
+## Success Criteria
+
+- [x] Batch call returns N media entries in request order.
+- [x] Duplicate paths in same batch or already delivered paths fail cleanly.
+- [x] Single-path `send_file` tests still pass.
+
+## Risk Assessment
+
+Changing media structs has a broad compile surface. Keep new fields additive with `omitempty` JSON tags and update only conversion points that need captions.

+
+# Phase 3: Channel Capability and Telegram Grouping
+
+## Overview
+
+Add channel capability metadata and implement Telegram media-group delivery for compatible batches while preserving ordered fallback elsewhere.
+
+## Requirements
+
+- Functional: Telegram sends compatible media in album chunks of 2-10.
+- Functional: Telegram documents group only with documents, audio only with audio, and photo/video may group together.
+- Functional: mixed or singleton chunks fall back to existing per-file send helpers.
+- Functional: caption behavior remains stable: first item uses shared message content when no per-file caption exists; oversized captions become follow-up text.
+- Non-functional: existing thread/reply behavior stays intact; reply applies to first grouped chunk only.
+
+## Architecture
+
+Add small reusable capability structs in `internal/channels/capabilities.go`, then keep platform-specific grouping logic in Telegram package:
+- Capability data exposes max batch count and grouping mode for docs/tests.
+- Telegram helper classifies outbound media as photo/video/audio/document, validates size, prepares captions, and emits chunks.
+- `sendMediaMessage` chooses media-group chunks only when safe; all other cases call the existing `sendPhoto`, `sendVideo`, `sendAudio`, `sendVoice`, or `sendDocument` helpers.
+
+## Related Code Files
+
+- Modify: `internal/channels/capabilities.go`
+- Modify: `internal/channels/telegram/send.go`
+- Modify/Create: `internal/channels/telegram/*_test.go`
+- Modify: `internal/channels/discord/send_media.go` only if regression tests expose a real compatibility gap.
+
+## Implementation Steps
+
+1. Add channel capability metadata for Telegram and Discord; Slack is media-capable but no single-message multi-file guarantee in this phase.
+2. Add Telegram pure helpers for chunking compatible media batches.
+3. Implement `sendMediaGroup` with `telego.SendMediaGroupParams` and file seek/open handling.
+4. Keep fallback path for audio-as-voice, oversized image-as-document, singleton chunks, and any group send error where retrying single sends is safer.
+5. Run `go test ./internal/channels/telegram ./internal/channels/discord ./internal/channels/slack`.
+
+## Success Criteria
+
+- [x] Telegram helper tests prove 2-10 compatible grouping and ordered fallback.
+- [x] Discord existing multi-file upload path remains unchanged.
+- [x] Slack fallback continues ordered file uploads plus text.
+
+## Risk Assessment
+
+Telegram media groups are not transactional across fallback retries. Avoid marking success until the channel call returns nil; do not hide partial failure.

+# Phase 4: Regression Verification and Ship
+
+## Overview
+
+Run focused regression checks, update docs if behavior changed, review locally, then ship a beta PR.
+
+## Requirements
+
+- Functional: acceptance criteria from issue #172 are demonstrably covered for tool API, Telegram, and Discord/fallback behavior.
+- Non-functional: no syntax/build errors in touched packages.
+- Non-functional: no secrets or local env values in plan/issue/PR text.
+
+## Architecture
+
+Verification should stay package-focused unless touched files force broader coverage. Full integration tests are not required because no DB schema or live channel credential path changes.
+
+## Related Code Files
+
+- Modify if warranted: `docs/05-channels-messaging.md`
+- Modify if warranted: `docs/project-changelog.md`
+- Read: `.github/workflows/ci.yaml` for PR check expectations if local commands differ.
+
+## Implementation Steps
+
+1. Run focused tests:
+   - `PATH=/usr/local/go/bin:$PATH go test ./internal/tools ./internal/channels/telegram ./internal/channels/discord ./internal/channels/slack`
+2. Run compile checks:
+   - `PATH=/usr/local/go/bin:$PATH go test ./internal/channels/... ./internal/tools/...`
+   - `PATH=/usr/local/go/bin:$PATH go build ./...`
+   - `PATH=/usr/local/go/bin:$PATH go build -tags sqliteonly ./...`
+3. Update docs/changelog only if public behavior changed enough to warrant it.
+4. Run local pending diff review and fix Critical/Important findings.
+5. Commit, push branch, create PR to `dev`, run PR review/fix/reply, then add `ready to ship beta`.
+
+## Success Criteria
+
+- [x] Focused tests pass.
+- [x] PG and SQLite builds pass.
+- [x] PR targets `dev` and links issue #172.
+- [x] Source issue and PR carry `ready to ship beta`; `ready to cook` removed after PR review.
+
+## Risk Assessment
+
+`go build ./...` may expose pre-existing platform/toolchain issues in unrelated packages. If so, record exact package/error and still run focused touched-package verification.

+# Issue 172 Multi Attachment Delivery
+
+## Overview
+
+Implement GitHub issue #172 in beta mode. Add a batch attachment tool API that lets agents queue multiple existing workspace files in one tool call, preserve order/caption metadata, and let channel senders group uploads where the platform supports it.
+
+Scout summary:
+- `send_file` currently accepts one `path` and returns one `Result.Media` entry: `internal/tools/send_file.go`.
+- `write_file(deliver=true)` already queues one file and marks it in `DeliveredMedia`: `internal/tools/filesystem_write.go`.
+- `message` can publish embedded multiple `MEDIA:` refs in one `bus.OutboundMessage`: `internal/tools/message.go`.
+- Tool result media flows through `agent.MediaResult` and `appendMediaToOutbound`; captions must be copied there or batch metadata is lost.
+- Discord already sends multiple files in one message: `internal/channels/discord/send_media.go`.
+- Telegram currently loops one media item at a time, even though `telego.SendMediaGroup` supports 2-10 album items with type restrictions: `internal/channels/telegram/send.go`.
+- Slack uploads files one by one, so it remains ordered fallback unless/until a safe multi-upload contract is added: `internal/channels/slack/send.go`.
+
+Scope boundary:
+- In scope: backend tool contract, media caption propagation, Telegram grouped album chunks, Discord regression coverage, ordered fallback for unsupported/mixed cases.
+- Out of scope: web UI changes, inbound media debounce, database migrations, WhatsApp/Zalo/Lark deep batching beyond existing ordered send behavior.
+

+# Validation and Red-Team Report
+
+## Validation
+
+- `ck plan validate --strict plans/260612-1708-issue-172-multi-attachment-delivery/plan.md` passed with 0 errors and 0 warnings.
+- Repo matched source issue: `digitopvn/goclaw`, default branch `dev`.
+- Source issue #172 is open and asks for multi-attachment delivery with channel limits, fallback, metadata preservation, and tests for Telegram plus another supported channel.
+- Verified Telegram `telego.SendMediaGroupParams.Media` requires 2-10 items and docs/audio same-type grouping in local module `github.com/mymmrac/telego@v1.6.0`.
+
+## Red-Team Findings
+
+- Accepted: caption metadata would be lost unless copied from `bus.MediaFile` through `agent.MediaResult` into `bus.MediaAttachment`. Plan updated to include these conversion points.
+- Accepted: Telegram cannot group every mixed batch. Plan limits media groups to photo/video together, document-only, and audio-only chunks; singleton and unsupported cases use existing ordered sends.
+- Rejected: adding live channel integration tests. They require credentials and would make CI flaky; pure helper tests plus existing sender path tests are enough for this scope.
+- Deferred: Slack true multi-file batch. Current Slack path uploads files in order and preserves thread routing; Slack's upload behavior needs separate product/API decision.

+None.
