Agent-created skills via `skill_save` and patched skills via `skill_patch` are forced to `Untrusted` + `NeedsReview`, and `skill_patch` refuses edits that touch the YAML frontmatter, blocking an injected agent from flipping `auto_load` or clearing `needs_review`. `odek skill promote --force` clears the flag after explicit user review. +- **Skill provenance gate** (`internal/skills/loader.go` + `cache.go` + `tools.go`) — `Skill.Provenance{Untrusted, Sources, NeedsReview}`. NeedsReview skills pin to Lazy regardless of `auto_load` and are excluded from lazy trigger matching (the matchers in `reloadLocked` are built only from promotable skills), so a flagged skill cannot be injected into context on a keyword match. Skills scanned from the project-local `./.odek/skills/` directory are distrusted like `./odek.json`: they are forced to `NeedsReview` with `"project"` in `Sources` until promoted.

Agent-created skills via `skill_save` and patched skills via `skill_patch` are forced to `Untrusted` + `NeedsReview`, and `skill_patch` refuses edits that touch the YAML frontmatter, blocking an injected agent from flipping `auto_load` or clearing `needs_review`. All skill-body scans (load, save, patch, suggestion) go through `guard.ScanContentWithScope`, so the fast local rule scan runs even when the `skills` guard scope or the guard itself is disabled; the sidecar second opinion only runs when the scope is enabled (default: on). Taint derives from `memory.ToolCallTaints`, whose always-external set covers `browser` / `http_batch` / `transcribe` / `session_search` / `web_search` / `vision` / `delegate_tasks` (`shell` is deliberately excluded as the primary work tool). `odek skill promote --force` clears the flag after explicit user review. - **Sub-agent damage cap** (`cmd/odek/subagent.go::applySubagentTrust`) — `delegate_tasks` carries `trust_level` + `max_risk`. The mutated `DangerousConfig` is passed into the sub-agent's `odek.Config` so the engine enforces the cap. Untrusted ⇒ NonInteractive=deny, Destructive/CodeExec/Install/SystemWrite/NetworkEgress/Unknown/Blocked all forced to Deny. `max_risk` ⇒ everything above cap forced to Deny. MCP tools are not loaded into untrusted sub-agents, because the MCP `ToolAdapter` does not perform its own danger check and would otherwise bypass the cap. - **FD-based API key handoff** (`cmd/odek/subagent_key.go`) — parent writes key to a 0600 tempfile, immediately `unlink()`s, passes the FD via `cmd.ExtraFiles`. Sub-agent reads from `$ODEK_API_KEY_FD` and closes. Key never in `/proc//environ`. - **Approver friction** (`internal/danger/approver.go`, `cmd/odek/wsapprover.go`, `cmd/odek/shell.go`, `cmd/odek/perf_tools.go`) — both TTYApprover and WSApprover engage friction mode after 3 approvals of the same class in 60s: require typing literal `approve`, 1.5s pause.
