refactor(code-mode)!: rename Code Mode "skills" to "snippets" - #1114
Merged
Conversation
Disambiguates Code Mode's runtime code library from the agent/provider "skills" systems (the SKILL.md packaging feature). Breaking rename of the package, its public API, and the Code Mode wire contract. - Package: `@tanstack/ai-code-mode-skills` -> `@tanstack/ai-code-mode-snippets` (dir `packages/ai-code-mode-skills` -> `packages/ai-code-mode-snippets`) - API: `codeModeWithSkills`->`codeModeWithSnippets`, `snippetsToTools`, `snippetsToBindings`, `selectRelevantSnippets`, `createSnippetManagementTools`, `createSnippetsSystemPrompt`, `generateSnippetTypes`, `createFile/MemorySnippetStorage`, all `Snippet*` types/options - Runtime tools: `search_snippets`/`get_snippet`/`register_snippet`; sandbox binding prefix `snippet_` - Wire contract (`@tanstack/ai`): events `code_mode:snippet_*`, `snippet:registered`; types `CodeModeSnippet*Event`/`SnippetRegisteredEvent` - Sandbox hook (`@tanstack/ai-code-mode`): `createCodeModeTool` option `getSkillBindings` -> `getSnippetBindings` - Updated example `ts-code-mode-web`, docs, and reference docs Agent/provider skills (packages/*/skills, SKILL.md, provider skills-wire) are intentionally untouched.

📝 WalkthroughWalkthroughThis PR renames Code Mode skills to snippets across public APIs, runtime tools, storage, events, examples, documentation, and tests. It adds snippet package exports, memory storage, integration documentation, provider adapters, and structured-output CLI testing. ChangesCode Mode snippets migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This breaking rename changes the public API and runtime contract, but the current revision also retains concrete merge risks: concurrent file-backed updates may lose snippet data or trust statistics, runtime logs may expose sensitive inputs and code, newly registered snippets may not become available during an active interaction, and several validation examples can pass incorrectly or fail for the wrong reason. These issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@docs/code-mode/code-mode-with-snippets.md`:
- Around line 36-56: Add the text language identifier to both fenced code blocks
in the documentation, including the workflow diagram near the existing snippet
and the second block around the later referenced section, so each opening fence
uses text and MD040 is satisfied.
- Around line 62-64: Update the model IDs in the examples at the documented
locations, including the selectRelevantSnippets and main chat descriptions, to
use the current supported metadata entries such as gpt-5.6 and claude-sonnet-5;
replace older IDs consistently while preserving each example’s intended model
role.
In `@docs/comparison/vercel-ai-sdk.md`:
- Line 603: Update the comparison text around the snippet library description to
avoid claiming that trust strategies gate promotion to first-class tools;
describe them only as tracking trust levels, consistent with
code-mode-with-snippets.md and the current implementation.
In `@docs/reference/interfaces/CodeModeSnippetCallEvent.md`:
- Around line 2-6: Regenerate the reference source links for
CodeModeSnippetCallEvent at
docs/reference/interfaces/CodeModeSnippetCallEvent.md lines 2-6 to point to
packages/ai/src/types.ts lines 1558-1561; update CodeModeSnippetErrorEvent at
docs/reference/interfaces/CodeModeSnippetErrorEvent.md lines 2-6 to lines
1571-1574; and update CodeModeSnippetResultEvent at
docs/reference/interfaces/CodeModeSnippetResultEvent.md lines 2-6 to lines
1562-1569.
In `@docs/tools/provider-skills.md`:
- Around line 21-23: Update the distinction mentioning
`@tanstack/ai-code-mode-snippets` so it states that snippets execute locally in
the application’s Code Mode sandbox, rather than saying they are evaluated
client-side; preserve the surrounding comparison with Provider Skills.
In `@examples/ts-code-mode-web/package.json`:
- Line 26: Update the `@tanstack/ai-code-mode-snippets` dependency in package.json
from workspace:* to workspace:^, preserving the existing dependency name and
placement.
In `@packages/ai-code-mode-snippets/README.md`:
- Line 175: Update the fenced code block in the README to specify the text
language, using a text-labeled fence so markdownlint MD040 passes.
- Around line 149-153: Update the Returns documentation for codeModeWithSnippets
to name the returned field toolsRegistry instead of registry, while preserving
the existing description of its ToolRegistry contents.
In `@packages/ai-code-mode-snippets/src/create-snippets-system-prompt.ts`:
- Around line 147-171: Update both register_snippet examples in
packages/ai-code-mode-snippets/src/create-snippets-system-prompt.ts:147-171 and
:260-284 so inputSchema and outputSchema are passed as JSON-serialized schema
strings, matching the registration contract and simulated registration flow.
Apply the same format to both examples; no other payload fields need changing.
In `@packages/ai-code-mode-snippets/src/snippets-to-tools.ts`:
- Around line 186-205: Remove the runtime logging in the snippet execution flow
that exposes input, wrapped or stripped code, and error stacks; update the
relevant execution and error-handling symbols around stripTypeScript to log only
safe contextual metadata, or gate any detailed diagnostics behind an explicit
debug setting with sensitive values redacted.
- Around line 257-260: Update the statistics update flow around
storage.updateStats so updates for the same snippet are serialized or performed
through an atomic storage operation, preventing concurrent calls from
overwriting execution count, success rate, or trust level; preserve the
non-blocking behavior and existing failure handling.
In `@packages/ai-code-mode-snippets/src/storage/file-storage.ts`:
- Around line 155-162: Validate snippet names before any filesystem path
construction in the storage get, save, and delete operations, including
deleteSnippet, enforcing the documented snake_case identifier format and
rejecting traversal values such as “..”. Ensure invalid names are rejected
without filesystem access, and add regression coverage for traversal attempts
across all three operations.
- Around line 135-150: Serialize the index read-modify-write sequence in the
save flow around loadIndex, index mutation, and saveIndex, and apply the same
protection in deleteSnippet. Use an atomic index commit with a cross-process
lock or transactional storage when the directory may be accessed by multiple
server processes, preventing concurrent saves or deletes from overwriting each
other.
In `@packages/ai-code-mode-snippets/test-cli/live-test.ts`:
- Around line 91-105: Update the destructuring of both codeModeWithSnippets
calls to use the returned toolsRegistry field, then pass each registry to chat
via the toolRegistry option instead of mapping tools1 or tools2 directly.
Preserve dynamic tool registration for both conversation flows.
In `@packages/ai-code-mode-snippets/test-cli/registry-test.ts`:
- Around line 405-446: Update the verification logic around the stream2
tool_result handling and result.phases.verification so it records whether
add_two_numbers returned the expected successful value of 30 without an error,
then require hasInputSchema, hasExecute, and that successful result alongside
the existing checks in success.
In `@packages/ai-code-mode-snippets/test-cli/structured-output-test.ts`:
- Around line 256-259: Update the pass condition in the structured-output test
to require result.codeModeExecuted and resultCorrect in addition to the existing
required-field checks, so it passes only when Code Mode ran and the reported
result is correct.
In `@packages/ai-code-mode-snippets/test-cli/tests.ts`:
- Around line 125-129: Rename the test case identifier from SKL to a
snippets-specific identifier such as SNP, and update every CLI selector or
registry reference that uses SKL so the test remains discoverable and runnable.
In `@packages/ai-code-mode/skills/ai-code-mode/SKILL.md`:
- Around line 184-195: Update the chat invocation in the codeModeWithSnippets
flow to pass toolsRegistry through the toolRegistry option, rather than
supplying a one-time toolsRegistry.getTools() snapshot, so tools registered
later by register_snippet are discoverable.
In `@packages/ai/skills/ai-core/tool-calling/SKILL.md`:
- Line 626: Update the description of `@tanstack/ai-code-mode-snippets` in the
Provider Skills comparison so it no longer claims snippets are executed
client-side; describe them as running in the configured Code Mode isolate or
through application-controlled server handlers, while preserving the distinction
from provider-managed bundles.

| 1. **Snippet selection** (`selectRelevantSnippets`) — A single chat call using the adapter you provide. It sends the last 5 conversation messages plus a catalog of snippet names/descriptions, and asks the model to return a JSON array of relevant snippet names. This should be a cheap/fast model (e.g., `gpt-4o-mini`, `claude-haiku-4-5`). | ||

|
||
| 2. **Main chat** — The primary `chat()` call with your full model. This is where the LLM reasons, calls tools, writes code, and registers snippets. |

Do not describe trust as a tool-promotion gate.
docs/code-mode/code-mode-with-snippets.md states at Line 270 that trust level is metadata only and does not currently gate execution. This sentence gives the opposite guarantee. Change it to describe trust strategies as tracking trust levels, or update both documents and the implementation consistently.
Proposed wording
-Trust strategies control what gets promoted to a first-class tool.
+Trust strategies track snippet trust levels; they do not currently gate tool exposure.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Use the returned toolsRegistry field.
codeModeWithSnippets returns toolsRegistry, not tools. These destructures do not type-check. If type checking is bypassed, tools1.map and tools2.map access undefined. Pass the returned registry to chat through toolRegistry to preserve dynamic registration.

Assert successful snippet output.
A tool_result only proves that the tool call completed. It does not prove that add_two_numbers returned 30 without an error. Include hasInputSchema, hasExecute, and a successful expected result in the phase success condition.

`createFileSnippetStorage` used the LLM-supplied snippet name directly as an on-disk path segment (`join(directory, name)`) in get/save/delete, so a name like `../../x` could read, write, or delete files outside the storage directory. Snippet names are already identifier-shaped (they double as `snippet_<name>` sandbox tool names), so names are now validated against `/^[A-Za-z0-9_-]+$/`: save/delete throw and get returns null for unsafe names. Addresses a CodeRabbit finding (pre-existing under the old skills storage). Adds regression tests covering traversal attempts and ordinary names.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Use a test-unique outside path.
join(dir, '..', 'escape') can already exist outside this test's temporary directory. The assertion can then fail although validation prevented the write. Generate a unique sibling name and use that same name in the traversal input and assertion.
Proposed fix
+ const outsideName = `escape-${crypto.randomUUID()}`
+ const traversalName = `../${outsideName}`
- const unsafeNames = ['..', '../escape', 'a/b', 'foo/../bar', '/abs', 'win\\seg']
+ const unsafeNames = ['..', traversalName, 'a/b', 'foo/../bar', '/abs', 'win\\seg']

What & why
Code Mode's runtime code library was called skills, which collides with the unrelated agent/provider skills systems (the
SKILL.mdpackaging feature). This renames the Code Mode concept to snippets to disambiguate. It's a deliberate breaking change to the package name, its public API, and the Code Mode wire contract.Agent/provider skills (
packages/*/skills,SKILL.md, provider*-skills-wire) are intentionally untouched.Changes
