+# Technical Context
+
+## Current State
+
+- Relevant crates/files:
+  - `crates/skilllite-agent/src/llm/mod.rs`
+  - `crates/skilllite-agent/src/task_planner.rs`
+  - `crates/skilllite-agent/src/prompt.rs`
+  - `crates/skilllite-assistant/src-tauri/src/life_pulse.rs`
+  - `crates/skilllite-assistant/src-tauri/src/skilllite_bridge/integrations/evolution_ui/authorize.rs`
+- Current behavior:
+  - `LlmClient::embed` and `TaskPlanner::parse_task_list` build debug/error
+    previews with byte slicing.
+  - Desktop status/backlog/authorization paths pass `--workspace`, but life-pulse
+    growth and the detached authorized-capability run do not.
+  - `get_skill_full_docs` applies a security notice to high-risk `SKILL.md`
+    content only; references and bash-tool up-front docs are not covered.
+
+## Architecture Fit
+
+- Layer boundaries involved:
+  - `skilllite-agent` owns prompt construction and LLM/task-planner handling.
+  - The Tauri desktop bridge owns subprocess argument construction for the CLI.
+  - `skilllite-core` already owns high-risk skill doc pattern detection.
+- Interfaces to preserve:
+  - Existing CLI subcommand and flag names.
+  - Existing `LoadedSkill` and metadata structures.
+  - Existing evolution DB schema and feedback APIs.
+
+## Dependency and Compatibility
+
+- New dependencies: None.
+- Backward compatibility notes:
+  - Desktop subprocesses still run the same commands, with explicit workspace
+    added to align execution with existing UI reads/writes.
+  - Prompt content gains the existing security notice only for already-detected
+    high-risk patterns.
+
+## Design Decisions
+
+- Decision: Use `safe_truncate` for all affected preview strings.
+  - Rationale: It is the local helper already used by the recent UTF-8 fixes.
+  - Alternatives considered: Ad hoc `char_indices` helpers in each file.
+  - Why rejected: More duplication and higher risk than reusing the established helper.
+- Decision: Pass `--workspace <workspace>` to desktop background evolution runs.
+  - Rationale: The CLI now resolves DB paths from explicit workspace, and UI
+    read/enqueue paths already pass it.
+  - Alternatives considered: Change current directory or set only environment.
+  - Why rejected: Current directory and env resolution already diverged in the
+    regression scenario.
+- Decision: Reuse `SKILL_MD_SECURITY_NOTICE` for high-risk reference/bash docs.
+  - Rationale: The policy text already exists for the same threat model.
+  - Alternatives considered: Add a new warning or block references.
+  - Why rejected: New policy wording/docs are unnecessary for this minimal fix.
+
+## Open Questions
+
+- [x] Is a docs sync required? No public command/env/security policy semantics are
+  changed; this only applies existing notices to missed prompt injection paths.
+- [x] Are schema or migrations involved? No.

+# PRD
+
+## Background
+
+The daily critical-bug automation reviewed recent UTF-8 truncation and evolution
+workspace DB fixes. The review found two crash-class UTF-8 preview paths that still
+slice strings by byte index, desktop evolution subprocesses that do not carry the
+workspace selected by the UI, and prompt injection paths that bypass the existing
+high-risk `SKILL.md` security notice for some documentation sources.
+
+## Objective
+
+Prevent concrete crash and workspace-split scenarios with minimal changes, and
+reuse the existing skill documentation security notice for all injected high-risk
+skill docs.
+
+## Functional Requirements
+
+- FR-1: Error preview truncation for embedding responses and task-planner parse
+  failures must be UTF-8 safe.
+- FR-2: Desktop life-pulse growth and authorized capability background runs must
+  invoke `skilllite evolution run` with `--workspace <selected workspace>`.
+- FR-3: High-risk skill reference docs and bash-tool docs injected into prompts
+  must include the existing security notice.
+- FR-4: Tests must exercise non-ASCII boundary cases and prompt notice injection.
+
+## Non-Functional Requirements
+
+- Security: Do not relax sandbox, command, network, or approval policies.
+- Performance: Keep checks local string scans only; no additional I/O beyond already
+  loaded documentation files.
+- Compatibility: Preserve existing public CLI flags, env vars, response formats,
+  and skill metadata structures.
+
+## Constraints
+
+- Technical: Avoid broad refactors; use existing helpers such as `safe_truncate`
+  and `has_skill_md_high_risk_patterns`.
+- Timeline: N/A for autonomous execution; scope is bounded to the identified
+  critical bug paths.
+
+## Success Metrics
+
+- Metric: Non-ASCII preview paths panic-free.
+- Baseline: Byte slicing at fixed offsets can panic when a multibyte character
+  crosses the boundary.
+- Target: Regression tests pass and code uses Unicode-safe truncation.
+
+## Rollout
+
+- Rollout plan: Ship as a small bug-fix PR on the automation branch.
+- Rollback plan: Revert the single fix commit if regressions appear; no migrations
+  or persisted schema changes are involved.
