# Session Orchestration Audit: S6-3dc26da3 **Session:** philly-search-engine-marketing, 2026-06-29 15:08–16:58 UTC **Transcript:** 120 jsonl lines, 3.3MB (largely user-submitted images) **Scope:** 21 assistant turns, 13 human prompts, 1 Agent spawn **Policy Under Audit:** Project-local CLAUDE.md (lines 72–102), "All work follows an orchestrator-subagent pattern" --- ## Question 1: Are subagents getting called when they should be? **Verdict:** PASS **Evidence:** - Line 98: Agent spawned for multi-file update task (TODO.md + logs/2026-06-29.md) - Lines 20–85: Conversational debugging of Zapier error handling (no delegation, correct — this is advice/troubleshooting, not "work") - Line 89 (user): "Update todos and documentation based on this conversation" — triggers explicit work task - Line 97 (orchestrator): "I'll handle the documentation updates in parallel" — signals intent to delegate - Fact-sheet confirms 1 spawn, 0 orchestrator tool calls (Read/Write/Bash/Grep) The project's local CLAUDE.md (line 72) is strict: *"All work follows an orchestrator-subagent pattern. No exceptions."* The orchestrator correctly identified the file-update task as delegable work and spawned an Agent. The conversational turns before that are appropriately handled directly (no restriction against speaking directly; the restriction is on direct tool calls). --- ## Question 2: Is the correct model chosen per subagent — highest reasonable quality at lowest cost? **Verdict:** FAIL **Evidence:** - Line 98 Agent spawn: `input` contains only `description` and `prompt` — NO `model` field - Fact-sheet line: "model param: (ABSENT)" → "resolved model: claude-sonnet-4-6" - Task: Read 2 files (TODO.md, logs/2026-06-29.md), append structured items, create log if missing, return summary - Project CLAUDE.md model routing (lines 86–91): ``` | Haiku | File reads, simple edits, formatting, search | | Sonnet | Feature implementation, refactoring, tests | | Opus | Architectural decisions, complex debugging | ``` This task is **file reads + simple edits + formatting** — a textbook Haiku task. Sonnet is 4x more expensive and unnecessary for mechanical file operations. **Violation:** Project CLAUDE.md line 86 states "Every Agent spawn passes model explicitly" (implied reference to the table above). The spawn did not include `model: "haiku"` despite the task profile being unambiguously haiku-level. **Cost impact:** Agent consumed 28.8k subagent tokens (reported in line 105 task-notification ``). At typical rates, a Haiku agent would have consumed ~7–10k tokens for the same work. Estimated overspend: ~3–4x cost. --- ## Question 3: Is the orchestrator planning/grouping tasks to maximize efficient context-window use? **Verdict:** MIXED (structure sound, execution not independently verifiable) **Evidence:** - Single Agent spawn with 2039-char prompt (well-structured, ~2KB) - Prompt includes explicit instructions: - Files to read (with fallback logic: "create if missing") - Two specific TODO items with full context (Gary's priority, Zapier blocker details) - Four session-log entry points covering the decision, implementation, blocker, and next steps - Instruction to "Return a brief summary" - Agent returned after 55.2 seconds with 6 tool_uses (likely: 2 Reads, 2 Writes, 1–2 git ops for potential commit/log) The prompt is well-factored — it frontloads all context (no need for back-and-forth). The task scope is narrow enough that one Agent call suffices. The agent's token count (28.8k) is reasonable for the work scope. **However:** Cannot verify from the orchestrator's window whether the agent *internally* batched reads/writes efficiently or made sequential redundant operations. The agent's own transcript is off-limits per line 99 guidance ("do NOT Read or tail this file via the shell tool"). --- ## Question 4: Is the orchestrator avoiding reading files it does NOT need (that the subagent would read anyway)? **Verdict:** PASS **Evidence:** - Fact-sheet: "calls: 0, bytes read: 0" (pre-spawn and post-spawn) - Grep of transcript: No `"name":"Read"` tool uses anywhere - Orchestrator did not self-read TODO.md or logs/2026-06-29.md before delegating Project CLAUDE.md line 81 explicitly forbids this: *"Does NOT read files to prepare delegation specs — write specs from the user's request."* The orchestrator inlined all context (Gary's email content, Zapier error details, decision rationale) from the conversation into the Agent prompt, requiring zero file reads. Correct pattern. --- ## Question 5: Is the orchestrator sharing too much context with subagents (filling their windows / clouding judgment)? **Verdict:** PASS **Evidence:** - Agent prompt: 2039 characters of task instructions - Content: structured, specific, actionable - Clear "add these two items to TODO.md" (with bulleted details) - Clear "add this session entry to logs/2026-06-29.md" (with bulleted details) - Clear instruction to create log file if missing and follow the pattern of other logs/ - No extraneous conversation transcript dumped into the prompt - No "here's everything the user said, figure it out" vagueness The prompt is dense but focused. It reads as a well-written specification, not a context-dump. The agent consumed 28.8k tokens total (subagent tokens per line 105); that's a reasonable allocation for the complexity of the task. --- ## Question 6: Is the orchestrator even following the ORCHESTRATION.md instructions? **Verdict:** FAIL (partial compliance) **Evidence:** **What was done correctly:** - Line 77–80 (orchestrator responsibilities): - ✓ Interpreted user request as delegable work - ✓ Delegated via Agent tool (not direct Read/Write/Bash) - ✓ Did not call Read/Write/Bash/Grep directly - ✓ Did not read files to prepare specs - Line 84 (subagent returns): - ✓ Agent returned summary (task-notification at line 105: *"Both files are updated. Here's what was done:"*) - ✓ Included artifact paths (README.md implied; full structure in summary) **What was done incorrectly:** - Line 86 (model routing): States "Every Agent spawn passes model explicitly" - ✗ Spawn at line 98 has NO `model` field in input - ✗ Cascaded default to sonnet instead of haiku - ✗ Violates explicit policy: "Haiku for file reads, simple edits, formatting" This is a clear violation of a single, high-stakes instruction in the project's local policy. --- ## Question 7: Is the orchestrator requesting/receiving back only the context it needs, rather than a full context dump from the subagent? **Verdict:** PASS **Evidence:** - Task-notification at line 105: Contains task metadata + concise summary of actions taken - Status: completed - Summary: "Both files are updated. Here's what was done:" - Details: Two bulleted items for TODO.md, four bulleted items for logs/2026-06-29.md entry - Usage stats: subagent_tokens, tool_uses count, duration_ms - Orchestrator's response (line 109): *"Documentation updated. TODO.md has both items at the top of the active section, and today's session log is created. Ready for the SDD Contact Us schema when you are."* - Acknowledges completion - Confirms both files were touched - Moves forward without demanding a full file dump or line-by-line verification - No off-limits file read (per line 99 guidance) The subagent's summary was sufficient. The orchestrator neither over-requested nor over-received context. --- ## Summary of Misses 1. **Model routing violation (Question 2):** The Agent spawn at line 98 omitted the required `model: "haiku"` parameter. Project policy is explicit and non-negotiable: *"Every Agent spawn passes model explicitly."* The task (file reads + edits) is a textbook Haiku case. **Estimated cost impact:** 3–4x overspend (sonnet vs. haiku pricing). 2. **All other questions:** Orchestrator's delegation pattern, context handling, and response flow are compliant with the project's CLAUDE.md policy and the global ORCHESTRATION.md rubric. --- ## Candidate Eval Trigger / Criterion When a project has a strict agent-model routing table (e.g., "Haiku for file reads/edits/formatting"): - **Criterion:** Every Agent spawn must include an explicit `model: "haiku"` (or the table's default) parameter. Default cascade (allowing the system to choose sonnet) is a violation, not a fallback. - **Orchestrator should:** Check the task type against the project's model routing table *before* writing the Agent call. Pass the required model parameter unconditionally. - **Signal for rejection:** A project CLAUDE.md with a model routing table + any Agent spawn that lacks an explicit model field matching that table. --- ## Appendix: Transcript Anomaly The 3.3MB transcript with only 120 lines and 21 assistant turns is explained by: - Lines 10, 51, 63: User messages containing embedded images (750KB, 1.4MB, 787KB respectively) - Image data is stored inline in the JSON (base64 or direct encoding) - No orchestrator tool calls, so no Read/Write/Bash results to inflate the transcript further - The bulk is user input (images), not orchestrator work or subagent verbosity This is not an orchestration efficiency issue; it's a client-interaction pattern (user sharing screenshots for Zapier troubleshooting).
