feat: /gsd-settings-integrations — configure third-party search and review integrations (closes #2529) (#2604)

* feat(#2529): /gsd-settings-integrations — third-party integrations command Adds /gsd-settings-integrations for configuring API keys, code-review CLI routing, and agent-skill injection. Distinct from /gsd-settings (workflow toggles) because these are connectivity, not pipeline shape. Three sections: - Search Integrations: brave_search / firecrawl / exa_search API keys, plus search_gitignored toggle. - Code Review CLI Routing: review.models.{claude,codex,gemini,opencode} shell-command strings. - Agent Skills Injection: agent_skills.<agent-type> free-text input, validated against [a-zA-Z0-9_-]+. Security: - New secrets.cjs module with ****<last-4> masking convention. - cmdConfigSet now masks value/previousValue in CLI output for secret keys. - Plaintext is written only to .planning/config.json; never echoed to stdout/stderr, never written to audit/log files by this flow. - Slug validators reject path separators, whitespace, shell metacharacters. Tests (tests/settings-integrations.test.cjs — 25 cases): - Artifact presence / frontmatter. - Field round-trips via gsd-tools config-set for all four search keys, review.models.<cli>, agent_skills.<agent-type>. - Config-merge safety: unrelated keys preserved across writes. - Masking: config-set output never contains plaintext sentinel. - Logging containment: plaintext secret sentinel appears only in config.json under .planning/, nowhere else on disk. - Negative: path-traversal, shell-metachar, and empty-slug rejected. - /gsd:settings workflow mentions /gsd:settings-integrations. Docs: - docs/COMMANDS.md: new command entry with security note. - docs/CONFIGURATION.md: integration settings section (keys, routing, skills injection) with masking documentation. - docs/CLI-TOOLS.md: reviewer CLI routing and secret-handling sections. - docs/INVENTORY.md + INVENTORY-MANIFEST.json regenerated. Closes #2529 * fix(#2529): mask secrets in config-get; address CodeRabbit review cmdConfigGet was emitting plaintext for brave_search/firecrawl/exa_search. Apply the same isSecretKey/maskSecret treatment used by config-set so the CLI surface never echoes raw API keys; plaintext still lives only in config.json on disk. Also addresses CodeRabbit review items in the same PR area: - #3127146188: config-get plaintext leak (root fix above) - #3127146211: rename test sentinels to concat-built markers so secret scanners stop flagging the test file. Behavior preserved. - #3127146207: add explicit 'text' language to fenced code blocks (MD040). - nitpick: unify masked-value wording in read_current legend ('****<last-4>' instead of '**** already set'). - nitpick: extend round-trip test to cover search_gitignored toggle. New regression test 'config-get masks secrets and never echoes plaintext' verifies the fix for all three secret keys. * docs(#2529): bump INVENTORY counts post-rebase (commands 84→85, workflows 82→83) * fix(test): bump CLI Modules count 27→28 after rebase onto main (CI #24811455435) PR #2604 was rebased onto main before #2605 (drift.cjs) merged. The pull_request CI runs against the merge ref (refs/pull/2604/merge), which now contains 28 .cjs files in get-shit-done/bin/lib/, but docs/INVENTORY.md headline still said "(27 shipped)". inventory-counts.test.cjs failed with: AssertionError: docs/INVENTORY.md "CLI Modules (27 shipped)" disagrees with get-shit-done/bin/lib/ file count (28) Rebased branch onto current origin/main (picks up drift.cjs row, which was already added by #2605) and bumped the headline to 28. Full suite: 5200/5200 pass.

+## Reviewer CLI Routing
+
+`review.models.<cli>` maps a reviewer flavor to a shell command invoked by the code-review workflow. Set via [`/gsd-settings-integrations`](COMMANDS.md#gsd-settings-integrations) or directly:
+
+```bash
+gsd-sdk query config-set review.models.codex    "codex exec --model gpt-5"
+gsd-sdk query config-set review.models.gemini   "gemini -m gemini-2.5-pro"
+gsd-sdk query config-set review.models.opencode "opencode run --model claude-sonnet-4"
+gsd-sdk query config-set review.models.claude   ""   # clear — fall back to session model
+```
+
+Slugs are validated against `[a-zA-Z0-9_-]+`; empty or path-containing slugs are rejected. See [`docs/CONFIGURATION.md`](CONFIGURATION.md#code-review-cli-routing) for the full field reference.
+
+## Secret Handling
+
+API keys configured via `/gsd-settings-integrations` (`brave_search`, `firecrawl`, `exa_search`) are written plaintext to `.planning/config.json` but are masked (`****<last-4>`) in every `config-set` / `config-get` output, confirmation table, and interactive prompt. See `get-shit-done/bin/lib/secrets.cjs` for the masking implementation. The `config.json` file itself is the security boundary — protect it with filesystem permissions and keep it out of git (`.planning/` is gitignored by default).

+### `/gsd-settings-integrations`
+
+Interactive configuration of third-party integrations and cross-tool routing.
+Distinct from `/gsd-settings` (workflow toggles) — this command handles
+connectivity: API keys, reviewer CLI routing, and agent-skill injection.
+
+Covers:
+
+- **Search integrations:** `brave_search`, `firecrawl`, `exa_search` API keys,
+  and the `search_gitignored` toggle.
+- **Code-review CLI routing:** `review.models.{claude,codex,gemini,opencode}`
+  — a shell command per reviewer flavor.
+- **Agent-skill injection:** `agent_skills.<agent-type>` — skill names
+  injected into an agent's spawn frontmatter. Agent-type slugs are validated
+  against `[a-zA-Z0-9_-]+` so path separators and shell metacharacters are
+  rejected.
+
+API keys are stored plaintext in `.planning/config.json` but displayed masked
+(`****<last-4>`) in every interactive output, confirmation table, and
+`config-set` stdout/stderr line. Plaintext is never echoed, never logged,
+and never written to any file outside `config.json` by this workflow.
+
+```bash
+/gsd-settings-integrations           # Interactive config (three sections)
+```
+
+See [`docs/CONFIGURATION.md`](CONFIGURATION.md) for the per-field reference and
+[`docs/CLI-TOOLS.md`](CLI-TOOLS.md) for the reviewer-CLI routing contract.

+## Integration Settings
+
+Configured interactively via [`/gsd-settings-integrations`](COMMANDS.md#gsd-settings-integrations). These are *connectivity* settings — API keys and cross-tool routing — and are intentionally kept separate from `/gsd-settings` (workflow toggles).
+
+### Search API keys
+
+API key fields accept a string value (the key itself). They can also be set to the sentinels `true`/`false`/`null` to override auto-detection from env vars / `~/.gsd/*_api_key` files (legacy behavior, see rows above).
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `brave_search` | string \| boolean \| null | `null` | Brave Search API key used for web research. Displayed as `****<last-4>` in all UI / `config-set` output; never echoed plaintext |
+| `firecrawl` | string \| boolean \| null | `null` | Firecrawl API key for deep-crawl scraping. Masked in display |
+| `exa_search` | string \| boolean \| null | `null` | Exa Search API key for semantic search. Masked in display |
+
+**Masking convention (`get-shit-done/bin/lib/secrets.cjs`):** keys 8+ characters render as `****<last-4>`; shorter keys render as `****`; `null`/empty renders as `(unset)`. Plaintext is written as-is to `.planning/config.json` — that file is the security boundary — but the CLI, confirmation tables, logs, and `AskUserQuestion` descriptions never display the plaintext. This applies to the `config-set` command output itself: `config-set brave_search <key>` returns a JSON payload with the value masked.
+
+### Code-review CLI routing
+
+`review.models.<cli>` maps a reviewer flavor to a shell command. The code-review workflow shells out using this command when a matching flavor is requested.
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `review.models.claude` | string | (session model) | Command for Claude-flavored review. Defaults to the session model when unset |
+| `review.models.codex` | string | `null` | Command for Codex review, e.g. `"codex exec --model gpt-5"` |
+| `review.models.gemini` | string | `null` | Command for Gemini review, e.g. `"gemini -m gemini-2.5-pro"` |
+| `review.models.opencode` | string | `null` | Command for OpenCode review, e.g. `"opencode run --model claude-sonnet-4"` |
+
+The `<cli>` slug is validated against `[a-zA-Z0-9_-]+`. Empty or path-containing slugs are rejected by `config-set`.
+
+### Agent-skill injection (dynamic)
+
+`agent_skills.<agent-type>` extends the `agent_skills` map documented below. Slug is validated against `[a-zA-Z0-9_-]+` — no path separators, no whitespace, no shell metacharacters. Configured interactively via `/gsd-settings-integrations`.
+
+---
+
 ## Workflow Toggles

 All workflow toggles follow the **absent = enabled** pattern. If a key is missing from config, it defaults to `true`.

+
+- **Masking convention: `****<last-4>`** (e.g. `sk-abc123def456` → `****f456`).
+  Strings shorter than 8 characters render as `****` with no tail so a short
+  secret does not leak a meaningful fraction of its bytes. Unset values render

+- **Plaintext is never echoed by AskUserQuestion descriptions, confirmation
+  tables, or any log line.** It is not written to any file under `.planning/`
+  other than `config.json` itself.
+- **`config-set` output is masked** for keys in the secret set
+  (`brave_search`, `firecrawl`, `exa_search`) — see
+  `get-shit-done/bin/lib/secrets.cjs`.
+- **Agent-type and CLI slug validation.** `agent_skills.<agent-type>` and
+  `review.models.<cli>` keys are matched against `^[a-zA-Z0-9_-]+$`. Inputs
+  containing path separators (`/`, `\`, `..`), whitespace, or shell

+ *
+ * Covers:

+ *   - Workflow references the four search API key fields
+ *   - Workflow exposes review.models.{claude,codex,gemini,opencode} routing
+ *   - Workflow exposes agent_skills.<agent-type> injection input
+ *   - Masking convention (****last4) is documented in the workflow and the displayed
+ *     confirmation pattern does not echo plaintext
+ *   - config-set round-trips all integration keys through VALID_CONFIG_KEYS + dynamic patterns
+ *   - Config merge preserves unrelated keys
+ *   - /gsd:settings confirmation output mentions /gsd:settings-integrations
+ *   - Negative: invalid agent-type name (path traversal / special char) is rejected
+ *   - Negative: malformed review.models key is rejected
+ *   - Logging: plaintext API keys do not appear in any file written under .planning/
+ *     by the config-set flow other than config.json itself
