Summary of Session Work

User requested: Create an orchestration plugin in ~/dev/cc-plugins to version-control and back up the orchestration rules (previously a pilot section in CLAUDE.md).

Tool usage profile:

• Bash: 12 calls (exploration, directory creation, testing)
• Write: 5 calls (4 plugin files + 1 scratchpad)
• Read: 4 calls (requirements, CLAUDE.md, marketplace.json, settings.json)
• Edit: 4 calls (revert CLAUDE.md, register in marketplace.json, wire in settings.json)

Work segmented into phases:

1. Read requirements and existing pilot section (Lines 28, 50)
2. Explore existing plugin structure via find/grep (Lines 35, 82–115)
3. Create directory tree (Line 119)
4. Write 4 plugin files (Lines 125, 127, 135, 137)
5. Register and integrate: Edit marketplace.json + settings.json (Lines 146, 157)
6. Test the hook (Line 161+)

Seven-Question Rubric Audit

1. Are subagents getting called when they should be?

Verdict: PASS

Evidence: Zero Agent spawns (fact-sheet confirms, jsonl lines 1–183 contain no Agent tool_use). Flagged candidate work: Write ×4 spanning 4 distinct plugin files (lines 125, 127, 135, 137).

Reasoning: The orchestration policy states "Delegate only when work is parallelizable across independent files/subtasks, spans many files, or needs a large/isolated context." The 4 writes form a single coherent plugin with internal dependencies:

• inject.py reads the contents of ORCHESTRATION.md at runtime
• hooks.json references the path and filename of inject.py
• Both depend on plugin.json and ORCHESTRATION.md for semantic meaning

These are not independent — they are coordinated parts of one unit. The work was also integrated with edits to marketplace.json and settings.json for proper registration (lines 146, 157), which could not have been parallelized with the plugin creation. The single-session orchestration correctly kept this together and did not delegate.

2. Is the correct model chosen per subagent — highest reasonable quality at lowest cost?

Verdict: N/A

Evidence: No subagents spawned, so no model selection applies.

---

3. Is the orchestrator planning/grouping tasks to maximize efficient context-window use?

Verdict: PASS

Evidence:

• Phase 1 (exploration): Lines 28, 35, 50, 82–115. Bash grep commands referenced existing plugins (doc-hygiene, memory) and examined hook patterns (additionalContext, hookSpecificOutput — lines 109, 112, 115) before writing any code. This gathers reference context upfront.
• Phase 2 (creation): Directory structure created (line 119) before writes, making room in context for coordinated writes (lines 125–137).
• Phase 3 (integration): Reads marketplace.json and settings.json (lines 143, 149) after writes but before edits, ensuring the orchestrator understands what needs to be registered.
• Phase 4 (verification): Bash test of the hook (line 161) to confirm functionality.

Total 25 tool calls (12 Bash + 5 Write + 4 Read + 4 Edit) is reasonable for a full plugin creation task; phasing avoided context bloat.

---

4. Is the orchestrator avoiding reading files it does NOT need (that the subagent would read anyway)?

Verdict: PASS

Evidence:

• Read 1 (line 28): /home/jared/systems-admin/docs/orchestration-audit-prd.md — Requirements doc, essential to understand scope.
• Read 2 (line 50): /home/jared/systems-admin/CLAUDE.md — Source of the pilot section to be extracted; necessary.
• Read 3 (line 143): /home/jared/dev/cc-plugins/.claude-plugin/marketplace.json — Needed to understand how to register the new plugin in the local marketplace. Not redundant with prior exploration (prior Bash calls examined its existence but not its structure).
• Read 4 (line 149): ~/.claude/settings.json — Needed to understand hook wiring pattern before editing it.

No extraneous reads. Bash exploration (find, grep on existing plugins) was efficient discovery rather than full-file reads, and it directly informed the plugin design (grep for hookSpecificOutput — line 115 — led directly to the hook script structure in inject.py).

---

5. Is the orchestrator sharing too much context with subagents (filling their windows / clouding judgment)?

Verdict: N/A

Evidence: No subagents spawned; question does not apply.

---

6. Is the orchestrator even following the ORCHESTRATION.md instructions?

Verdict: PASS

Evidence: Policy from session context:

"Do single-file, ≤2-tool-call ops directly. Don't delegate them. Delegate only when work is parallelizable across independent files/subtasks, spans many files, or needs a large/isolated context."

Orchestrator invoked no Agent spawns. Boundary condition: 4 Writes (exceeds ≤2 threshold). However:

• The 4 writes are not parallelizable (they have internal dependencies as described in Question 1).
• They span many files, but those files form one logical unit with coordinated edits and testing in the same session.
• The orchestrator correctly identified that "spans many files" applies only when files are independent subtasks. These are not. Keeping them in a single session is appropriate.

Additionally, the Bash exploration phase (lines 82–115) is within the policy: "A short orienting Read before delegating is fine when the target file/path is uncertain. Don't delegate the orienting step itself." The orchestrator's exploration of existing plugin examples informed the design without delegating.

---

7. Is the orchestrator requesting/receiving back only the context it needs, rather than a full context dump from the subagent?

Verdict: N/A

Evidence: No subagents spawned; question does not apply.

---

Specific Findings on the Flagged Candidate (Write ×4, lines 125–137)

Flag origin: Heuristic flagged runs of ≥4 same-tool calls across distinct targets.

Assessment: This is a false positive in the delegation-candidate heuristic. The criterion "parallelizable across independent files/subtasks" does not apply here. The orchestrator correctly recognized that:

1. The plugin files form a coherent unit, not independent subtasks.
2. Integration work (marketplace, settings edits) depends on all plugin files being written first.
3. The entire sequence belongs in a single session for semantic coherence and testability.

A subagent spawn would have added friction (returning a summary of 4 created files + hook integration details) without saving context, since the orchestrator needs to verify the hook integration and test it (line 161). No delegation was needed.

Other Observations

Work Quality

• Directory structure created before writes (line 119), preventing path errors.
• Hook syntax validated by running the hook in the working environment (line 161, CLAUDE_PLUGIN_ROOT environment variable set).
• Permissions set (line 140: chmod +x).
• No retry loops or error recovery needed; indicates careful design before execution.

Context Efficiency

• The Read/Bash exploration phase (lines 28–115) took ~16 tool calls to gather context.
• The Write/Edit/integration phase (lines 125–161) was tightly executed with no back-and-forth.
• Model was claude-sonnet-5 throughout (appropriate for the mix of exploration + structured file creation).

No Red Flags

• No repeated reads of the same file (would indicate missing context or rework).
• No abandoned edits or reverted changes.
• Tool use pattern is monotonic: exploration → creation → integration → testing.

Verdict Summary

Question	Verdict	Confidence
1. Subagents when needed?	PASS	High
2. Model choice per subagent?	N/A	—
3. Task planning & grouping?	PASS	High
4. Avoiding unnecessary reads?	PASS	High
5. Context spillage to subagents?	N/A	—
6. Following ORCHESTRATION.md?	PASS	High
7. Compact subagent returns?	N/A	—

Overall: PASS. The orchestrator correctly resisted delegating a multi-file write sequence that appears to exceed the ≤2-tool-call threshold, because the files are not independent and form one logical unit. Exploration was well-organized, tool calls were lean, and integration was tight. No delegation was warranted, and none was invoked.
