fix(agent-sessions): session checks, vitals and turn labels - #1120
Conversation
…le prompts Symptom: the Prompt cache check warned "Cache hit rate 0% over N calls; N missed the cache" on sessions whose prompts were all too short to cache. Seen on DSPy (prompts peak 870 tokens, OpenAI minimum 1024), Google ADK, LangChain, Haystack, CrewAI and Claude Agent SDK (Haiku 4.5 prompts of 1.2K-2.3K tokens against its 4,096-token minimum) test sessions. Cause: promptCacheCheck judged every call after the first, whatever its prompt size. Fix: calls under 1024 prompt tokens (the smallest minimum OpenAI, Anthropic and Gemini cache) are left out of the judgement, and a session whose calls report a cache-write bucket but never wrote or read the cache is skipped: nothing reached the model's minimum, or caching is off. The "too few calls" message now counts the calls actually judged.
…adline
Symptom: the Provider errors check read "All 48 model calls were answered
first time" on an OpenRouter Broadcast session of 16 calls ("All 30" for
10), and "All 16 model calls" on a Google ADK session with llmCalls 8.
Cause: buildSessionChecks passed the count of every inference-classified
span (session-checks.ts providerCheck call), so OpenRouter's `provider
attempt N` and `generation` children and ADK's `call_llm` wrapper were
counted beside the call they belong to.
Fix: the headline uses summary.work.llmCalls, the netted count the
session header already shows.
Symptom: on Google ADK sessions the Prompt cache check read "0% over 15 calls" (a1) and "over 19 calls" (b) while the session had 8 and 10 model calls: the checks did not net ADK's duplicate reporter pair. Cause: promptCacheCheck took every inference-classified span, so ADK's `call_llm` wrapper and the `generate_content` span beneath it, both stamped with the same usage, were judged as two calls each. Fix: session-summary exports sessionLlmCalls, the netted call list behind work.llmCalls, and the cache check reads it. The provider headline half of the same symptom is fixed in the previous commit.
Symptom: vitals read 204.8 s of agent time in a 125.5 s OpenRouter Broadcast session with no parallel work. Cause: computeAgentTime charged every inference span its full duration, and Broadcast nests a `provider attempt N` and a `generation` span (both op `chat`) under each `LLM Generation`, so one call was charged up to three times. Google ADK's `call_llm` over `generate_content` doubles the same way. Fix: an inference span inside another inference span is the same call observed twice; only the outermost is charged. A TTFT that only a nested level reported still splits the call.
…rk spans Symptom: every turn of a checkpointed LangGraph thread (OpenInference LangChain dual-write) was labeled with turn 1's prompt, e.g. all a1 turns 1-6 read "Hi! Briefly introduce yourself.". Cause: turnLabel (session-turns.ts) fell back to the first span in start order with any user message. The LangGraph `model` node CHAIN span starts before its ChatOpenAI call and carries only the thread's first message. Fix: after the anchor, model calls are asked first, as the transcript's userRows already does; other spans remain the last resort.
Symptom: every smolagents turn label and the session title read "New task:". Cause: proseLine (session-turns.ts) labels a turn with the first non-empty line of the user message, and smolagents sends every task as "New task:\n<task>". Fix: a first line of at most three words ending in a colon is a lead-in; the line after it labels the turn. A longer sentence ending in a colon, or a lead-in with nothing after it, is kept as before.
Symptom: a Microsoft Agent Framework workflow session showed its one-span `workflow.build` trace as Turn 1 (no label, no agent, 1 span), the real run as Turn 2, and get_agent_session returned no title. Cause: `workflow.build` carries the session's id in its own trace and is read as an agent root by its name, so buildSessionTurns opened a turn on it; the summary title is turn 1's label. Fix: on the agent-root and per-trace rules, where the boundary is a heuristic, an anchor whose spans hold no model or tool call, no user message and nothing failed joins the next turn, as spans before the first anchor join turn 1. Conversation-id turns are explicit and kept, and a session with no work anywhere keeps its anchors.
A captured prompt can be tens of kilobytes; the label reads at most two non-empty lines, so it stops collapsing whitespace after them.
…t call, in the prompt-cache check Follow-up to the uncacheable-prompt fix: the size filter ran after dropping the first call, so a short opening call (a title or router call) was dropped instead of the first long call, which writes the cache and then read as a miss.
…rn labels Follow-up to the lead-in fix: any first line of three words ending in a colon was skipped, so a user's "Fix this:" over pasted code labeled the turn with the code's first line. The rule now matches the framework's literal heading.

🔴 Agent-only turns merge into later turns
When an agent invocation has no model call, opened merges its turn into the next busy turn. Distinct invocations disappear, and pauses between turns become false mid-turn stalls.
Learn more
Agent-root boundaries represent distinct invocations even when an invocation has no model or tool spans. The new opened predicate treats such a turn as empty and folds it forward if any later turn has work. stallFindings then examines both invocations as one turn and marks their idle gap as a stall. The session also loses a turn in its work count and transcript.
Example: An invocation at 0–1 seconds has no child call; another invocation at 60–70 seconds has a model call. Both are agent roots, but the first is removed and the 59-second pause is reported as a stall inside the remaining turn.
Recommended fix: Distinguish setup-only roots such as workflow.build from genuine invocation roots before folding buckets. Preserve genuine agent invocations as boundaries even without captured calls, and keep between-turn gaps outside stallFindings.

Fixed in efd5c06: a workless anchor now folds only when the next turn starts within 5 s of it ending (setup such as MAF's workflow.build). One followed by a pause stays its own turn, so the pause is never read as a stall. Test: "keeps a workless anchor followed by a pause as its own turn".

🔴 Nested model calls lose inference time
When a model call runs beneath another inference span, outermostCall treats both as one call. Distinct nested calls lose their inference time even when separated by an agent or tool.
Learn more
Agent time previously summed every inference span. The new ancestor walk assumes every nested inference span describes its outermost inference ancestor, even when the spans represent separate requests. It also crosses agent and tool spans, where a child request can be independent of its enclosing request. The existing countedLlmCalls deliberately counts multiple children under one SDK wrapper as separate calls when the wrapper rolls them up.
Example: A three-second SDK generateText wrapper contains two one-second doGenerate requests with separate usage. The call counter reports two calls, but agent time reports only the wrapper's three seconds and never charges either request separately; with a ten-second wrapper around two concurrent ten-second requests, the reported time is ten instead of twenty seconds.
Recommended fix: Identify observation pairs using the same per-call evidence as usage netting instead of suppressing all inference descendants by ancestry. Retain separate request durations when an inference parent wraps multiple calls or a nested agent/tool starts its own inference.

Partly fixed in 429379c: the walk now stops at an agent or tool span, so a model call made by a tool or sub-agent inside another call is charged again. Nesting directly under an inference span still charges only the outer span, by design. Its duration already covers its children, and summing them double counts the call: the bug here was OpenRouter's LLM Generation + provider attempt + generation reading 204.8 s in a 125.5 s session. Usage netting can't pair these: Broadcast's nested spans carry no usage. Concurrent calls under a single inference span don't appear in any of the 53 captures.

🟡 Gateway cache usage disappears from checks
When app and gateway spans share a response ID, sessionLlmCalls can retain the app span without cache buckets. The cache check then skips recorded gateway hits and misses.
Learn more
The check now consumes one representative span per model call. countedLlmCalls resolves duplicate response IDs using a claimed-usage preference and keeps the first observation when both claim usage. The repository's app-and-gateway example gives the app and gateway the same response ID and token total. If the gateway records cache usage but the earlier app span only reports total input tokens, the app wins and the cache check no longer sees the gateway measurement.
Example: Four app calls each report 2,000 input tokens without cache fields; their gateway mirrors share response IDs and each report 1,500 cached tokens. The app observations win ties, leaving zero reporting calls and a skipped cache check instead of the measured hit rate.
Recommended fix: Select a cache-reporting observation for each response ID specifically for promptCacheCheck, or aggregate the cache fields across observations without counting a call twice. Keep the session's token representative unchanged if its current selection is needed elsewhere.

Fixed in 3b9a6e5: when the span counted for a call reported no cache fields, the check reads the same response id's observation that did. Test: "judges the prompt cache off a gateway mirror when the counted span has none".

… on Anthropic only Follow-up to the uncacheable-prompt fix (#25). The never-written skip read a zero cache-write bucket as "nothing was cacheable", but OpenAI- model emitters (CrewAI, Haystack, LiteLLM, Mastra, Microsoft Agent Framework, Strands, Vercel AI SDK) stamp a zero write bucket on every call, so an OpenAI session with long prompts and a real 0% hit rate was skipped instead of warned. The rule now applies only when every reporting call is an Anthropic call. The separate "too few calls" early return is dropped: the cacheable-call gate below it covers it.
…ot that it is one call Follow-up to the agentTime fix (#39): an inference span inside another is only the same model call under direct nesting; the rule holds because the nested span's time is inside the outer span's. Comment only.
Symptom: Strands TS replies cut off at the output limit were never flagged; the Reply length check passed. Cause: Strands TS writes its finish reasons camelCase (`maxTokens`), and the truncation and refusal matchers (session-findings.ts TRUNCATION_FINISH_REASONS, session-summary.ts REFUSAL_FINISH_REASONS) only lowercased before comparing against `max_tokens`/`content_filter`. Fix: a shared finishReasonsIn helper matches on the reason lowercased with separators removed, so `maxTokens`, `MAX_TOKENS` and `max_tokens` are one reason.
…ht into the next turn Follow-up to the empty-turn fix (#41), from review. A workless agent invocation followed by a pause was folded into the next turn, which then read the pause as a stall inside it. The fold now needs the next turn to start within 5 s of the workless anchor ending (setup such as MAF's `workflow.build`), and merging moves the accumulated bucket forward in place instead of re-copying it for each workless anchor in a row.
…n agentTime Follow-up to the agentTime fix (#39), from review. The walk to the outermost inference span crossed agent and tool spans, so a model call a tool or sub-agent made inside another call was charged nothing. The walk now stops at an agent or tool: only inference spans nested directly (or through non-work spans) share the outer span's time.
…that reported it Follow-up to the per-call cache fix (#40), from review. When an app span and its gateway's mirror share a response id, the netted call list can keep the app span, which may carry no cache fields, and the cache check then skipped a session the mirror measured. For such a call the check now reads the same response's observation that reported cache usage.

…mpt-cache check Follow-up to the uncacheable-prompt fix (#25). The never-written rule was session-wide and keyed on provider `anthropic` with a write bucket of 0, so it missed Claude through OpenRouter (flue: provider `openrouter`, prompts 1,043-1,392 tokens under Haiku 4.5's 4,096 minimum) and OpenRouter Broadcast (provider `anthropic`, write key absent, prompts 1.2K-2.6K), and a mixed session fell back to judging every call. A call is now left out on its own when it is Claude (provider `anthropic` or a `claude` model) and neither wrote nor read the cache, like the 1024-token cut; the rest of the session is still judged.
…the finish-reason match Follow-up to the finish-reason fix. The case it fixes today is Vercel AI SDK's kebab-case ai.response.finishReason: a `content-filter` refusal read as passed and now warns. Strands TS camelCase reasons live in output-message parts and reach the checks only once those are read.

…sses every Claude minimum Follow-up to the uncacheable-prompt fix (#25). Leaving out every Claude call that neither wrote nor read the cache also hid real misses when the emitter does not report writes: 8 Claude calls with 10K-token prompts and 4 misses read "passed 90% over 3 calls" instead of "51% over 7". Such a call is now left out only when its prompt is also under 4,096 tokens, the largest Claude minimum; above it, reading nothing is a miss. The cold/warm cache fixture is back on a Claude model with no write bucket and 10K prompts, and must warn.
Maple reviewConfidence 3/5 · needs attention Warning This review ended early; what follows is what it established. Reworks the agent-session checks and turns: the prompt-cache check skips prompts below the provider's cache minimum and judges each model call once, agentTime charges an outer inference span once, the provider headline counts calls rather than observations, and workless setup anchors fold into the next turn. Contained to analysis code and well covered by new tests.
