fix(web-chat): let an operator choose the chat agent, and stop a raw web_fetch buying an LLM summary of markup by senamakel · Pull Request #6586 · tinyhumansai/openhuman

senamakel · 2026-09-24T00:06:08Z

Why

Two defects found while running scripts/life-scenarios against deepseek/deepseek-v4.1-flash. They are independent; the first is the more consequential.

1. The benchmark has never run the agent it ships with

scripts/life-scenarios/agent-life-scenarios.toml declares max_iterations = 40, with a comment saying the orchestrator's default 15 "is not enough to read a mailbox and write three artifacts". It never took effect on the default driver.

web_chat::session::pick_target_agent_id was hard-coded:

pub(super) fn pick_target_agent_id(_config: &Config) -> String {
    "orchestrator".to_string()
}

The config parameter was threaded in and ignored, so the web-chat path — channel_web_chat, what the desktop composer calls and what run.mjs drives by default — always ran orchestrator at its declared cap. run.mjs defaulted --agent to "" and only applied it on the rpc driver.

So baggage-policy spent 15 model calls researching, obtained every fact its grader asks for (22"×14"×9", personal item, $45/$55 checked fees), wrote zero files, and ended with iteration cap for agent_id=orchestrator: definition.max_iterations=15. The turn reported the work as still to do.

Raising a cap could not fix this. A named definition's effective_max_iterations() overwrites agent.max_tool_iterations at the single resolution point in session_host/builder/factory.rs, so an agent that declares its own cap cannot be lifted by config — the lever has to be which definition answers.

Fix. A new [agent] chat_agent_id, read by pick_target_agent_id, defaulting to orchestrator when unset or blank. Blank falls back rather than routing at an id the registry cannot answer: a typo in an optional setting should not take chat down.

Deliberately not done: adding an agent_id field to channel_web_chat. That is a product wire contract, and widening it so a benchmark can pick an agent is the wrong seam. The RPC path already takes one per call.

run.mjs sets it through config.update_agent_settings on the running core, with a read-back retry, rather than pre-writing the file — for the reason the BYOK block ten lines above already documents. prepareHome writes users/local/config.toml, but the core mints its own user dir at boot (users/local-dragonfly/…) whose config takes precedence. I made exactly that mistake first: the value was written, the banner said agent=life_scenarios, and the core still logged agent_id=orchestrator.

Verified live: applying definition iteration cap for agent_id=life_scenarios: definition.max_iterations=40 … effective=40.

2. `raw: true` buys an LLM summary of unconverted markup

web_fetch runs tinyjuice::compressors::html::html_to_markdown on HTML responses — web_fetch.rs:248 is !raw_requested && is_html(...). So raw: true switches the conversion off and the payload is raw markup, which then went into the summary stage.

One observed raw: true fetch of a 183 KB page cost 44,561 prompt tokens — over half that turn's entire summarizer budget — to have a model paraphrase scripts and CSS for a page the same turn had already read as clean Markdown. It is also the wrong answer to the question asked: a caller who wants the body as sent wants the bytes, not a summary of them.

Fix. is_raw_fetch records such calls in before_tool (where the arguments are visible) and the summary stage is skipped for them in after_tool — the same seam artifact_reads already uses, following use_skill into its wrapped tool exactly as artifact_read_target does. Only the summary is skipped: the per-result cap and artifact spill still run, so the model gets a lossless file_read paging handle over the real markup, for no model call.

Tests

chat_agent_id_selects_the_web_chat_agent_and_defaults_to_the_orchestrator — selection, whitespace trimming, and blank/unset falling back.
only_a_raw_web_fetch_is_exempt_from_the_payload_summarizer — raw: false/null/absent/"true"-as-a-string all stay eligible; a raw argument on another tool does not qualify.
a_raw_fetch_wrapped_in_use_skill_is_still_a_raw_fetch — the wrapper is followed, but a wrapper naming another tool, or a malformed one, does not inherit the exemption.

cargo check clean. agent::tinyagents::middleware 114 passed / 0 failed; web_chat::session + config::ops + security::policy 302 passed / 0 failed. pnpm rust:layout and pnpm docs:check clean.

Note for anyone running the lib suite: config::ops::…::add_auto_approve_tool_appends_then_dedupes overflows its stack without RUST_MIN_STACK=16777216. Unchanged on main, not from this branch.

Merge notes

upstream/main restructured tool_output.rs while this branch was open — the summarizer and tokenjuice compaction are now one compact_tool_output stage with summary tickets and summary_focus. This branch had a change reordering those two stages; upstream's restructure supersedes it and I dropped mine, taking upstream's version wholesale. The raw: true exemption is re-applied on top of the new gate, where it matters more: that stage now spends a model call, and on unconverted markup it is pure waste.

Conflicts were otherwise struct-field lists (raw_fetches alongside upstream's focus_by_call / summary_focus_tools), kept on both sides. vendor/tinyjuice follows upstream to 8cae496 (v0.3.1); vendor/tinyagents is deliberately unchanged.

Not in this PR

deepseek-v4.1-flash emits tool calls unreliably — once as corrupted DeepSeek DSML framing around a file_write, and repeatedly as bare narration with no call at all. Filed as tinyhumansai/tinyagents#204, fixed in tinyhumansai/tinytools#22; the gitlink bumps follow separately.

Because of that, baggage-policy still scores 0 and I am not claiming these fixes move the suite. What is verified is narrower and worth having on its own: the benchmark now runs its declared 40-iteration agent instead of silently running a 15-iteration one, and a raw fetch no longer buys a model call to paraphrase minified JS. Showing a suite-level effect needs a model that reliably calls tools.

Summary by CodeRabbit

New Features
- Web chat can now be configured to use a runnable agent instead of the orchestrator. Leaving the setting blank or choosing an unavailable agent uses the orchestrator.
Bug Fixes
- Raw web-fetch results now bypass automatic summarization and compaction, while existing result limits and artifact handling remain in effect.
- Invalid agent selections are rejected without applying other changes in the same settings update.

When a tool returns an output with no content, the middleware now returns an empty string instead of failing. This prevents panics in downstream processing when tools produce empty results. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When a tool returns an output with no content, the middleware now returns an empty string instead of failing. This prevents crashes in agents that use tools which may produce empty results. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The documentation and debug messages listed the tool output processing steps in the wrong order. The actual pipeline applies TokenJuice compaction before the payload summarizer, so the comments and log messages now reflect that sequence to avoid confusion when reading the code. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Changed the `agent` field in the configuration schema from `agent_name` to `name` to align with the actual configuration structure used by the system. This ensures that agent configuration is properly validated and parsed according to the expected schema. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When a session ID is empty, the session lookup now returns an error instead of attempting to query the database with an invalid identifier. This prevents a potential panic or unexpected database error that could occur when an empty string is passed as a session ID. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The suite's benchmark agent now takes effect on both the desktop and rpc drivers, not only on the rpc path. The desktop driver selects it through a new `[agent] chat_agent_id` setting in the generated config, while the rpc path continues to pass it per call. This ensures multi-step scenarios with 40 iterations and the required tool belt run consistently regardless of which driver is used. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Add a test that verifies `pick_target_agent_id` returns the orchestrator when `chat_agent_id` is unset, returns the specified agent when set, trims whitespace from the value, and falls back to the orchestrator for blank values. This ensures the web-chat agent selection logic is correctly pinned and handles edge cases in configuration. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Adds a `chat_agent_id` field to the agent settings patch, allowing the web-chat path's target agent to be overridden at runtime. This field is settable over RPC rather than only in TOML because the on-disk config file may be overridden by per-user configuration, making runtime writes through the running core the only reliable way to apply the change. Auto-committed-on: dragonfly

Add a new optional `chat_agent_id` field to the agent settings update schema, allowing the web-chat path to route turns to a specific agent. An empty string clears the override back to the orchestrator, while omitting the field leaves the current value unchanged. Auto-committed-on: dragonfly

…field The `update_agent_settings` controller schema now accepts an optional `chat_agent_id` field that allows the web-chat path to route turns to a specific agent definition, with an empty string reverting to the orchestrator. This extends the existing timeout configuration to also support selecting a longer-running agent for chat interactions. Auto-committed-on: dragonfly

… scenarios The web-chat driver does not pass an agent_id per call, so the agent must be configured through the running core's RPC interface rather than by pre-writing the config file. The previous approach of writing to the config file before boot was ineffective because the active user directory is created at boot time and its configuration takes precedence, causing the benchmark to silently run with the orchestrator's default iteration cap instead of the intended agent. Auto-committed-on: dragonfly

# Conflicts: # scripts/life-scenarios/run.mjs

Add a helper function `is_raw_fetch` that identifies `web_fetch` calls made with `raw: true`, including those wrapped inside `use_skill`, and store the result in a new `raw_fetches` field on the middleware. This allows the payload summarizer to skip such calls, avoiding an expensive and pointless model call that would re-describe unconverted markup when the caller explicitly asked for the raw bytes. Auto-committed-on: dragonfly

When a tool call is identified as a raw fetch via `is_raw_fetch`, the middleware now records the call ID in a set of raw fetches and later skips semantic summarization for those results. This prevents the payload summarizer from processing large binary or raw responses that should be passed through unchanged, instead capping and spilling them to an artifact. Auto-committed-on: dragonfly

Consume the raw fetch entry unconditionally so the entry cannot outlive its call, even on the artifact-read early return below. This prevents a resource leak where the raw fetch entry would persist beyond its intended lifetime. Auto-committed-on: dragonfly

The TurnContextMiddleware and HandoffMiddleware now initialise a `raw_fetches` field on their shared state, and all test fixtures have been updated to include the new field. This prepares the middleware to track raw fetch results alongside artifact reads. Auto-committed-on: dragonfly

…eware/turn_context.rs Auto-committed-on: dragonfly

… summarizer Add two test cases that pin the behaviour of `is_raw_fetch`: one verifies that only a `web_fetch` call with `raw: true` is exempt from the payload summarizer, and another confirms that the exemption is preserved when the fetch is wrapped inside a `use_skill` invocation. Auto-committed-on: dragonfly

Add the `raw_fetches` field to `ToolOutputMiddleware` constructors and the `chat_agent_id` field to `AgentSettingsPatch` constructors in test files, matching recent changes to the production struct definitions. Auto-committed-on: dragonfly

Tiny Sweeper review

This PR introduces configurable web-chat agent selection via `chat_agent_id` and skips the payload summarizer for raw `web_fetch` results. All earlier high-severity findings about fallback, authorization, and clearing the override are resolved. Remaining findings are medium-severity requests for end-to-end tests.

What changed

Web-chat agent selection: `AgentConfig.chat_agent_id` added, validated via `is_runnable_agent_id`, and used in `pick_target_agent_id` to route turns. Raw-fetch summarizer exemption: `is_raw_fetch` detects `raw: true` on `web_fetch` (including via `use_skill`), and the middleware skips the payload summarizer for those calls. Life-scenarios benchmark script updated to set `chat_agent_id`, validate agent ID format, and restrict --agent to `life_scenarios` or `orchestrator`.

description

Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: This change introduces `[agent] chat_agent_id` to let operators select a web-chat agent (defaulting to the orchestrator) and exempts raw `web_fetch` results from the payload summarizer, fixing two independent defects. The code is structurally sound, well tested, and safe to merge.

Conclusion: Neutral
Scope reviewed: all assigned evidence
Lane summary: This PR adds a `chat_agent_id` config field for web-chat agent routing and a `raw_fetch` summarizer exemption for `web_fetch(raw: true)`. Both changes have external surface (RPC-settable config, tool output behaviour) but no end-to-end test in the CI suite drives them. Earlier findings requesting such coverage remain unresolved. The unit tests cover the logic but do not verify the behaviour through the full harness, leaving the changes e2e-uncovered and vulnerable to silent regressions in the wiring or runtime integration. Waiting on end-to-end jobs: `Rust E2E (mock backend)`, `Build Playwright E2E Artifact`, `E2E (Playwright / web lane)`, `Desktop E2E (full suite, 3 OS)`.

📝 Walkthrough

Walkthrough

The middleware skips payload summarization and TinyJuice processing for raw web-fetch results. Agent settings support a validated web-chat target agent, which web-chat sessions and the life-scenarios harness can select. The orchestrator prompt updates workflow delegation instructions.

Changes

Raw web-fetch result handling

Layer / File(s)	Summary
Detect and bypass raw-fetch summarization `crates/openhuman-core/src/agent/tinyagents/middleware/tool_output.rs`, `crates/openhuman-core/src/agent/tinyagents/middleware/tool_output_tests.rs`, `crates/openhuman-core/src/agent/tinyagents/middleware/turn_context.rs`, `crates/openhuman-core/src/agent/tinyagents/middleware_tests.rs`, `crates/openhuman-core/src/agent/tinyagents/middleware_tool_output_artifact_tests.rs`, `crates/openhuman-core/src/agent/tinyagents/middleware_tool_output_tests.rs`	The middleware detects direct `web_fetch` calls and `use_skill` wrappers with `raw: true`, then tracks those calls through result handling. Raw-fetch results skip the payload summarizer and TinyJuice, while existing result caps and artifact persistence remain applicable. Tests cover detection, bypass behavior, and tracking-field initialization.

Web-chat agent selection

Layer / File(s)	Summary
Add chat agent configuration and updates `crates/openhuman-core/src/config/schema/agent.rs`, `crates/openhuman-core/src/config/schemas/helpers.rs`, `crates/openhuman-core/src/config/schemas/schema_defs/agent.rs`, `crates/openhuman-core/src/config/ops/agent.rs`, `crates/openhuman-core/src/agent/session_host/builder/factory.rs`, `crates/openhuman-core/src/config/schemas/controllers/agent.rs`, `crates/openhuman-core/src/config/ops_agent_paths_tests.rs`, `crates/openhuman-core/src/config/ops_voice_and_autonomy_tests.rs`	Agent configuration and settings updates accept an optional `chat_agent_id`. Supplied values are trimmed and validated against runnable agent definitions before settings are assigned. Blank values clear the override, and omission leaves it unchanged.
Select the web-chat target agent `crates/openhuman-core/src/web_chat/session.rs`, `crates/openhuman-core/src/web_chat/session_checkout_tests.rs`	Web-chat session setup uses a configured runnable agent ID. It falls back to `orchestrator` when the setting is missing, blank, or invalid. Tests cover these cases.
Configure the benchmark agent `scripts/life-scenarios/run.mjs`	The harness defaults to `life_scenarios` for both drivers. It applies the selected ID through the running core and retries configuration read-back verification.

Orchestrator workflow instructions

Layer / File(s)	Summary
Update workflow delegation instructions `crates/openhuman-core/src/agent/registry/agents/orchestrator/prompt.md`	The prompt directs workflow authoring and discovery through the `workflows` skill. It specifies blocking delegation when the reply depends on the result and prohibits direct calls to owner-only authoring entries.

The life-scenarios runner now trims whitespace from the agentId option and treats an empty string as null, preventing a silent failure when the agent ID is not provided. Previously, an empty string would be passed to the config update, causing the orchestrator to run with its default iteration cap instead of the intended benchmark behavior.

Reject invalid --agent values before generating the config.

parseArgs accepts every --agent value. A value such as bad"name reaches the unescaped TOML interpolation in prepareHome. The running-core update stores the same value, and web chat then fails with agent definition 'bad"name' not found in registry. The RPC driver follows the same failing lookup.

Add a validation method to check whether an agent ID resolves to a runnable definition, and use it in two places: the config apply path now rejects unknown agent IDs with an error, and the web-chat session falls back to the default orchestrator when the configured ID is not runnable. This prevents configuration errors from taking down web chat and gives operators immediate feedback when setting an invalid agent.

…ad summary Add a test verifying that when a tool call uses the `raw` flag on `web_fetch`, the middleware does not prepare a payload summary and does not send a TinyJuice request, ensuring that raw fetches bypass the summarizer entirely.

Replace the complex instructions about spawning subagents for workflow building with a simpler directive to use the `workflows` skill directly, which delegates to the appropriate specialist internally.

Reorder the agent settings application so that the agent timeout is only written to config after all validation has passed, preventing a partial mutation when a mixed patch contains both a valid timeout and an invalid chat agent id. Add a test to verify that the config remains unchanged when a patch is rejected. Also restrict the life-scenarios script to only accept known agent identifiers.

Drive raw-fetch summarizer exemption with an end-to-end test

The exemption changes the model-facing behavior of a real web_fetch(raw: true) turn, but the available coverage does not drive that route through the harness. Add an end-to-end scenario that invokes raw fetch, verifies no summarizer call is made, and verifies oversized content remains recoverable through the artifact paging path.

+        if raw_fetch {


Add an end-to-end test for raw-fetch summarizer exemption

The new behavior is exercised only through is_raw_fetch; no test drives after_tool with a raw web_fetch result to prove that the payload summarizer is actually skipped while the result still follows the capping/artifact path. A regression in the call-id bookkeeping or middleware branch would leave the helper test passing while reintroducing the expensive summarizer call. Add a middleware-level test that invokes the before/after hooks with raw: true and asserts the summarizer is not called and the result is bounded as intended.

Additional critique observation

Test the after_tool raw-fetch skip branch

[RULE] missing-regression-test

This adds a stateful before_tool/after_tool path, but no test exercises a web_fetch call with raw: true (or the use_skill wrapper) and verifies that the payload summarizer is not invoked while the result still follows the cap and artifact path. A future change can easily break the call-id bookkeeping or wrapper detection without detection. Add a focused Rust domain test beside this middleware.

The current test coverage verifies only the classifier, not the stateful before_tool → after_tool path that consumes the call ID. Add a direct test for this branch, including a wrapped use_skill call, to ensure the recorded exemption reaches after_tool and is removed from the pending set.

Restrict chat-agent selection to authorized definitions

This forwards any caller-supplied string directly into AgentSettingsPatch; inputs such as "does-not-exist" are accepted at the new RPC boundary. The shown change does not validate the ID against the registered agent definitions or define a safe failure/fallback for an unknown selection, so a user can persist a target that the web-chat path cannot legitimately resolve. Validate the ID against the authorized registry before saving it, or reject the update with an error. The downstream apply_agent_settings implementation was not included here, so confidence is below certain, but this remains the previously identified high-impact routing issue.

+#[test]


Test the after_tool raw-fetch skip branch

These tests only call is_raw_fetch directly; they never invoke before_tool to record the call ID and after_tool to consume it and skip the summarizer. A regression in call-ID propagation, middleware ordering, or the stateful bookkeeping could therefore re-enable summarization while all of these tests remain green. Add a middleware-level test with a raw web_fetch result that asserts the summarizer is not invoked and the result still follows the cap/artifact path.

Exercise the self-capped tool spill path end to end

The new scenario covers only web_fetch with raw: true and uses a middleware with no artifact store and a 10 MB budget. It does not cover the separate production behavior for a tool declaring max_result_size_chars/max_result_bytes, where summarization must be skipped and the oversized result must take the spill-to-artifact path. That path remains vulnerable to regressions without an agent-run test using a real self-capped tool and asserting the persisted artifact or paging reference.

+    pub chat_agent_id: Option<String>,


Drive chat-agent routing through a real web-chat turn

The new setting is covered only by configuration-level tests. None of the changed tests drives a web-chat turn through the actual session checkout/routing path with a valid agent ID, then verifies that the selected definition is used. A regression in the consumer, persistence reload, or route resolution would leave these tests green while the setting appears to save successfully.

+    #[serde(default)]
+    pub(super) chat_agent_id: Option<String>,


Test clearing the web-chat agent override

The new empty-string clearing contract is exposed through the RPC deserializer, but this change adds no test proving that "" (and, per the existing patch contract, whitespace) removes a previously configured override while an omitted field leaves it unchanged. Without that test, the newly wired field can silently become a no-op or accidentally overwrite the current setting during config updates.

Drive raw-fetch exemption through the agent harness

The new behavior changes the model-facing result of a real web_fetch(raw: true) turn, but the added coverage only invokes the classifier directly. It does not verify that production tool execution records the raw-fetch call under the expected ID and reaches after_tool with the exemption intact. Add a harness-level scenario using the repository's mocked backend that asserts no summarizer request is made and oversized raw content remains recoverable through artifact paging.

Drive chat-agent routing through a real web-chat checkout

This test exercises only pick_target_agent_id with a global built-in registry. It does not build or check out the session that consumes the selected ID, nor execute a web-chat turn. A regression in checkout wiring could therefore leave this test green while all web-chat requests still run as the orchestrator. Add a test through the web-chat checkout/turn path that configures chat_agent_id and verifies the selected agent is used.

Drive chat_agent_id routing with an end-to-end test

These tests exercise only configuration validation and persistence. They do not run a web-chat turn through the session checkout/routing path, so a regression could cause a valid chat_agent_id to be ignored, routed to the wrong definition, or fail during agent construction while all of these tests remain green. Add a domain-level integration test using the existing test harness that sets a valid override and verifies the resulting web-chat turn uses that agent.

Drive raw-fetch summarizer exemption through an end-to-end test

The exemption for raw: true web_fetch is verified by a direct middleware unit test (a_raw_web_fetch_never_prepares_a_payload_summary), but no end-to-end test exercises the full tool execution path to confirm that the production tool loop records the raw-fetch identity and reaches the exemption. A regression in the wiring or metadata propagation could leave the unit test green while the actual feature breaks.

+pub(super) fn pick_target_agent_id(config: &Config) -> String {


Drive chat_agent_id routing with an end-to-end test

The pick_target_agent_id function and the [agent] chat_agent_id config field determine which agent definition handles web-chat turns, overriding the default orchestrator. This is a new behavioural path with RPC surface (update_agent_settings) and affects every web-chat turn. No end-to-end test sets chat_agent_id via RPC, triggers a web-chat turn, and asserts that the turn ran under the expected agent definition (e.g., researcher with its own max_iterations). A regression in the config resolution, registry lookup, or session factory wiring would go undetected.

Additional tests observation

Drive chat_agent_id routing through an end-to-end test

[RULE] missing-integration-test

The chat_agent_id field allows operators to switch the web-chat path to a different agent definition, but no end-to-end test verifies that a real web-chat turn uses the configured agent (e.g., researcher) and that its definition's effective_max_iterations takes effect. Only unit tests of pick_target_agent_id and validation exist; a wiring regression in the session checkout logic would not be caught.
