8ad7d78a70 fix: parameter coercion and validation for oneOf/anyOf/allOf schemas (#1397)
* fix: parameter coercion and validation for oneOf/anyOf/allOf schemas

WASM extension tools with multi-action schemas (e.g. github extension)
fail when the LLM passes numeric parameters as strings because the
coercion layer skips JSON Schema combinators. This causes serde
deserialization errors like `invalid type: string "100", expected u32`.

Add discriminated-union resolution to the coercion layer: for oneOf/anyOf,
match the active variant by const or single-element enum discriminators;
for allOf, merge all variants' properties. Also propagate combinator
awareness to schema validators, WASM wrapper helpers, and tool discovery
so they no longer reject or ignore valid combinator-based schemas.

* test: add e2e tests for oneOf discriminated union parameter coercion

Add three end-to-end tests using a fixture tool that mirrors the github
WASM tool's oneOf schema with #[serde(tag = "action")] deserialization.
Each test sends string-typed numeric/boolean params through the full
agent loop, verifying that coercion resolves them before serde runs:

- list_issues: limit "100" → 100 (integer in oneOf variant)
- get_issue: issue_number "42" → 42 (integer in different variant)
- create_pull_request: draft "true" → true (boolean in variant)

Without the coercion fix these fail with:
  invalid type: string "100", expected u32

* test: add real WASM github tool e2e tests with HTTP interception

Load the actual compiled github WASM binary, send params with string-typed
numbers through the coercion layer, and verify the WASM tool constructs
correct HTTP API calls via a new HTTP interceptor in the WASM wrapper.

Changes:
- Add `http_interceptor` field to `StoreData` and `WasmToolWrapper` so
  WASM tool HTTP requests can be captured/mocked in tests
- Make `prepare_tool_params` and `coercion` module public for integration tests
- Add 3 e2e tests loading the real github WASM binary:
  - list_issues: `limit: "50"` → URL contains `per_page=50`
  - get_issue: `issue_number: "42"` → URL contains `/issues/42`
  - list_pull_requests: `limit: "25"` → URL contains `per_page=25`

Tests gracefully skip if the WASM binary isn't compiled.

* refactor: simplify WASM e2e tests to use TestRig with with_wasm_tool()

Replace the manual WasmToolWrapper construction with TestRig integration:

- Add `with_wasm_tool(name, wasm_path, capabilities_path)` to TestRigBuilder
  that loads real WASM binaries and wires the shared HTTP interceptor
- Build the HTTP interceptor before tool registration so it can be shared
  between AgentDeps and WASM tool wrappers
- Rewrite github WASM e2e tests to use the standard trace pattern:
  TraceLlm sends tool calls with string params, http_exchanges specify
  expected outgoing requests and canned responses

The test code is now identical to other trace-based e2e tests — no custom
interceptors or manual WASM construction needed.

* fix: address review comments on combinator schema support

- Validate `has_combinators` checks array type (`.as_array().is_some()`)
  instead of bare `.is_some()` to reject malformed `{ "oneOf": {} }`
- Validate top-level `required` keys against merged combinator variant
  properties when no top-level `properties` exists (both validators)
- Deduplicate oneOf/anyOf handling into single loop in coercion.rs
- Revert `pub mod coercion` to private; only re-export `prepare_tool_params`
- Call `after_response` on interceptor after real HTTP when `before_request`
  returns None (recording mode correctness)
- Fix formatting (CI failure)

Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

* fix: address second round of review comments

- Fix headers deserialization bug: deserialize resp.headers_json as
  HashMap<String, String> then convert to Vec, not directly as Vec
- Sort interceptor headers for deterministic trace fixtures
- Update after_response comment: RecordingHttpInterceptor does exercise
  this path (returns None from before_request)
- Mark WASM tests #[ignore] instead of silent skip — avoids false-green
  CI while keeping them runnable with --ignored
- Fix with_wasm_tool signature: Option<PathBuf> instead of
  Option<impl Into<PathBuf>> which doesn't compile in nested position
- Fix with_wasm_tool doc comment to match actual behavior
- Revert prepare_tool_params to pub(crate) — no longer needed publicly

* fix: coerce empty strings to null for optional tool parameters

LLMs often send "" instead of null/omitting optional parameters, causing
parse errors in tools that expect typed values (e.g., timezone, schedule).

PR #1127 fixed this per-field in the time tool. This commit adds
dispatcher-level coercion so all tools benefit:

- Non-required properties with value "" are coerced to null at the
  object level (based on the schema's `required` array)
- Explicitly nullable schemas (`type: ["string", "null"]`) coerce ""
  to null in the per-value coercion path
- Required string-only fields keep "" unchanged

Closes #755

* feat: complete coercion coverage for $ref, nested combinators, and additionalProperties

Close remaining coercion gaps so 3rd-party tools (MCP servers, complex
WASM tools) work correctly:

- $ref resolution: inline all #/definitions/<name> and #/$defs/<name>
  references in a pre-pass before coercion, with depth limit (16) for
  circular ref safety
- Nested combinators: resolve_effective_properties now recurses into
  variants that themselves contain allOf/oneOf/anyOf (depth limit 4)
- additionalProperties inheritance: check allOf variants and matched
  oneOf/anyOf variant for additionalProperties schemas

New tests:
- resolves_ref_and_coerces_referenced_properties
- resolves_nested_refs_in_oneof_variants
- coerces_nested_combinators_allof_containing_oneof
- coerces_array_items_with_oneof_discriminator
- circular_ref_does_not_infinite_loop

* fix: address third round of review comments

- Validators: tighten has_combinators to require at least one object-typed
  variant (has type:"object" or properties), rejecting non-object combinator
  schemas like { "oneOf": [{"type":"integer"}] }
- Empty-string coercion: only coerce "" → null when schema allows null or
  doesn't allow string; pure type:"string" fields keep "" as meaningful
- Fix comment: "coerce to null" → "return unchanged" for empty strings
  with no type match (code returns None, not null)
- Redact credentials before passing to after_response interceptor to
  prevent secret leakage into recorded trace files
- Switch to tokio::fs::read for async WASM binary loading in test rig
- Add doc comment explaining soft URL check in WASM e2e tests

Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

* ci: retrigger after staging merge [skip-regression-check]

* fix: merge staging, report non-array combinator values as errors

Merge latest staging to fix CI (missing fallback_deliverable field).
Add explicit error reporting when oneOf/anyOf/allOf values are not
arrays in both strict and lenient validators.

Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

* fix: recurse into combinator variants that have properties but no explicit type

Both validators only recursed into variants with `type: "object"`,
missing variants that define `properties` without an explicit type
(common in allOf patterns). Now recurse when variant has either.

Philosophy

IronClaw is built on a simple principle: your AI assistant should work for you, not against you.

In a world where AI systems are increasingly opaque about data handling and aligned with corporate interests, IronClaw takes a different approach:

  • Your data stays yours - All information is stored locally, encrypted, and never leaves your control
  • Transparency by design - Open source, auditable, no hidden telemetry or data harvesting
  • Self-expanding capabilities - Build new tools on the fly without waiting for vendor updates
  • Defense in depth - Multiple security layers protect against prompt injection and data exfiltration

IronClaw is the AI assistant you can actually trust with your personal and professional life.

Install it with cargo, just make sure you have Rust installed on your computer.

# Clone the repository
git clone https://github.com/nearai/ironclaw.git
cd ironclaw

# Build
cargo build --release

# Run tests
cargo test

For full release (after modifying channel sources), run ./scripts/build-all.sh to rebuild channels first.

Database Setup

# Create database
createdb ironclaw

# Enable pgvector
psql ironclaw -c "CREATE EXTENSION IF NOT EXISTS vector;"

Configuration

Run the setup wizard to configure IronClaw:

ironclaw onboard

The wizard handles database connection, NEAR AI authentication (via browser OAuth), and secrets encryption (using your system keychain). Settings are persisted in the connected database; bootstrap variables (e.g. DATABASE_URL, LLM_BACKEND) are written to ~/.ironclaw/.env so they are available before the database connects.

Alternative LLM Providers

IronClaw defaults to NEAR AI but supports many LLM providers out of the box. Built-in providers include Anthropic, OpenAI, GitHub Copilot, Google Gemini, MiniMax, Mistral, and Ollama (local). OpenAI-compatible services like OpenRouter (300+ models), Together AI, Fireworks AI, and self-hosted servers (vLLM, LiteLLM) are also supported.

Select your provider in the wizard, or set environment variables directly:

# Example: MiniMax (built-in, 204K context)
LLM_BACKEND=minimax
MINIMAX_API_KEY=...

# Example: OpenAI-compatible endpoint
LLM_BACKEND=openai_compatible
LLM_BASE_URL=https://openrouter.ai/api/v1
LLM_API_KEY=sk-or-...
LLM_MODEL=anthropic/claude-sonnet-4

See docs/LLM_PROVIDERS.md for a full provider guide.

Security

IronClaw implements defense in depth to protect your data and prevent misuse.

WASM Sandbox

All untrusted tools run in isolated WebAssembly containers:

  • Capability-based permissions - Explicit opt-in for HTTP, secrets, tool invocation
  • Endpoint allowlisting - HTTP requests only to approved hosts/paths
  • Credential injection - Secrets injected at host boundary, never exposed to WASM code
  • Leak detection - Scans requests and responses for secret exfiltration attempts
  • Rate limiting - Per-tool request limits to prevent abuse
  • Resource limits - Memory, CPU, and execution time constraints
WASM ──► Allowlist ──► Leak Scan ──► Credential ──► Execute ──► Leak Scan ──► WASM
         Validator     (request)     Injector       Request     (response)

Prompt Injection Defense

External content passes through multiple security layers:

  • Pattern-based detection of injection attempts
  • Content sanitization and escaping
  • Policy rules with severity levels (Block/Warn/Review/Sanitize)
  • Tool output wrapping for safe LLM context injection

Data Protection

  • All data stored locally in your PostgreSQL database
  • Secrets encrypted with AES-256-GCM
  • No telemetry, analytics, or data sharing
  • Full audit log of all tool executions
