/analyze-project — Root Cause Analyst Workflow

Analyze AI-assisted coding sessions in ~/.gemini/antigravity/brain/ and produce a report that explains not just what happened, but why it happened, who/what caused it, and what should change next time.

Goal

For each session, determine:

1. What changed from the initial ask to the final executed work
2. Whether the main cause was:
   • user/spec
   • agent
   • repo/codebase
   • validation/testing
   • legitimate task complexity
3. Whether the opening prompt was sufficient
4. Which files/subsystems repeatedly correlate with struggle
5. What changes would most improve future sessions

Global Rules

• Treat .resolved.N counts as iteration signals, not proof of failure
• Separate human-added scope, necessary discovered scope, and agent-introduced scope
• Separate agent error from repo friction
• Every diagnosis must include evidence and confidence
• Confidence levels:
  • High = direct artifact/timestamp evidence
  • Medium = multiple supporting signals
  • Low = plausible inference, not directly proven
• Evidence precedence:
  • artifact contents > timestamps > metadata summaries > inference
• If evidence is weak, say so

---

Step 0.5: Session Intent Classification

Classify the primary session intent from objective + artifacts:

• DELIVERY
• DEBUGGING
• REFACTOR
• RESEARCH
• EXPLORATION
• AUDIT_ANALYSIS

Record:

• session_intent
• session_intent_confidence

Use intent to contextualize severity and rework shape. Do not judge exploratory or research sessions by the same standards as narrow delivery sessions.

---

Step 1: Discover Conversations

1. Read available conversation summaries from system context
2. List conversation folders in the user’s Antigravity brain/ directory
3. Build a conversation index with:
   • conversation_id
   • title
   • objective
   • created
   • last_modified
4. If the user supplied a keyword/path, filter to matching conversations; otherwise analyze all

Output: indexed list of conversations to analyze.

---

Step 2: Extract Session Evidence

For each conversation, read if present:

Core artifacts

• task.md
• implementation_plan.md
• walkthrough.md

Metadata

• *.metadata.json

Version snapshots

• task.md.resolved.0 ... N
• implementation_plan.md.resolved.0 ... N
• walkthrough.md.resolved.0 ... N

Additional signals

• other .md artifacts
• timestamps across artifact updates
• file/folder/subsystem names mentioned in plans/walkthroughs
• validation/testing language
• explicit acceptance criteria, constraints, non-goals, and file targets

Record per conversation:

Lifecycle

• has_task
• has_plan
• has_walkthrough
• is_completed
• is_abandoned_candidate = task exists but no walkthrough

Revision / change volume

• task_versions
• plan_versions
• walkthrough_versions
• extra_artifacts

Scope

• task_items_initial
• task_items_final
• task_completed_pct
• scope_delta_raw
• scope_creep_pct_raw

Timing

• created_at
• completed_at
• duration_minutes

Content / quality

• objective_text
• initial_plan_summary
• final_plan_summary
• initial_task_excerpt
• final_task_excerpt
• walkthrough_summary
• mentioned_files_or_subsystems
• validation_requirements_present
• acceptance_criteria_present
• non_goals_present
• scope_boundaries_present
• file_targets_present
• constraints_present

---

Step 3: Prompt Sufficiency

Score the opening request on a 0–2 scale for:

• Clarity
• Boundedness
• Testability
• Architectural specificity
• Constraint awareness
• Dependency awareness

Create:

• prompt_sufficiency_score
• prompt_sufficiency_band = High / Medium / Low

Then note which missing prompt ingredients likely contributed to later friction.

Do not punish short prompts by default; a narrow, obvious task can still have high sufficiency.

---

Step 4: Scope Change Classification

Classify scope change into:

• Human-added scope — new asks beyond the original task
• Necessary discovered scope — work required to complete the original task correctly
• Agent-introduced scope — likely unnecessary work introduced by the agent

Record:

• scope_change_type_primary
• scope_change_type_secondary (optional)
• scope_change_confidence
• evidence

Keep one short example in mind for calibration:

• Human-added: “also refactor nearby code while you’re here”
• Necessary discovered: hidden dependency must be fixed for original task to work
• Agent-introduced: extra cleanup or redesign not requested and not required

---

Step 5: Rework Shape

Classify each session into one primary pattern:

• Clean execution
• Early replan then stable finish
• Progressive scope expansion
• Reopen/reclose churn
• Late-stage verification churn
• Abandoned mid-flight
• Exploratory / research session

Record:

• rework_shape
• rework_shape_confidence
• evidence

---

Step 6: Root Cause Analysis

For every non-clean session, assign:

Primary root cause

One of:

• SPEC_AMBIGUITY
• HUMAN_SCOPE_CHANGE
• REPO_FRAGILITY
• AGENT_ARCHITECTURAL_ERROR
• VERIFICATION_CHURN
• LEGITIMATE_TASK_COMPLEXITY

Secondary root cause

Optional if materially relevant

Root-cause guidance

• SPEC_AMBIGUITY: opening ask lacked boundaries, targets, criteria, or constraints
• HUMAN_SCOPE_CHANGE: scope expanded because the user broadened the task
• REPO_FRAGILITY: hidden coupling, brittle files, unclear architecture, or environment issues forced extra work
• AGENT_ARCHITECTURAL_ERROR: wrong files, wrong assumptions, wrong approach, hallucinated structure
• VERIFICATION_CHURN: implementation mostly worked, but testing/validation caused loops
• LEGITIMATE_TASK_COMPLEXITY: revisions were expected for the difficulty and not clearly avoidable

Every root-cause assignment must include:

• evidence
• why stronger alternative causes were rejected
• confidence

---

Step 6.5: Session Severity Scoring (0–100)

Assign each session a severity score to prioritize attention.

Components (sum, clamp 0–100):

• Completion failure: 0–25 (abandoned = 25)
• Replanning intensity: 0–15
• Scope instability: 0–15
• Rework shape severity: 0–15
• Prompt sufficiency deficit: 0–10 (low = 10)
• Root cause impact: 0–10 (REPO_FRAGILITY / AGENT_ARCHITECTURAL_ERROR highest)
• Hotspot recurrence: 0–10

Bands:

• 0–19 Low
• 20–39 Moderate
• 40–59 Significant
• 60–79 High
• 80–100 Critical

Record:

• session_severity_score
• severity_band
• severity_drivers = top 2–4 contributors
• severity_confidence

Use severity as a prioritization signal, not a verdict. Always explain the drivers. Contextualize severity using session intent so research/exploration sessions are not over-penalized.

---

Step 7: Subsystem / File Clustering

Across all conversations, cluster repeated struggle by file, folder, or subsystem.

For each cluster, calculate:

• number of conversations touching it
• average revisions
• completion rate
• abandonment rate
• common root causes
• average severity

Goal: identify whether friction is mostly prompt-driven, agent-driven, or concentrated in specific repo areas.

---

Step 8: Comparative Cohorts

Compare:

• first-shot successes vs re-planned sessions
• completed vs abandoned
• high prompt sufficiency vs low prompt sufficiency
• narrow-scope vs high-scope-growth
• short sessions vs long sessions
• low-friction subsystems vs high-friction subsystems

For each comparison, identify:

• what differs materially
• which prompt traits correlate with smoother execution
• which repo traits correlate with repeated struggle

Do not just restate averages; extract cautious evidence-backed patterns.

---

Step 9: Non-Obvious Findings

Generate 3–7 findings that are not simple metric restatements.

Each finding must include:

• observation
• why it matters
• evidence
• confidence

Examples of strong findings:

• replans cluster around weak file targeting rather than weak acceptance criteria
• scope growth often begins after initial success, suggesting post-success human expansion
• auth-related struggle is driven more by repo fragility than agent hallucination

---

Step 10: Report Generation

Create session_analysis_report.md with this structure:

📊 Session Analysis Report — [Project Name]

Generated: [timestamp]
Conversations Analyzed: [N]
Date Range: [earliest] → [latest]

Executive Summary

| Metric | Value | Rating | |:---|:---|:---| | First-Shot Success Rate | X% | 🟢/🟡/🔴 | | Completion Rate | X% | 🟢/🟡/🔴 | | Avg Scope Growth | X% | 🟢/🟡/🔴 | | Replan Rate | X% | 🟢/🟡/🔴 | | Median Duration | Xm | — | | Avg Session Severity | X | 🟢/🟡/🔴 | | High-Severity Sessions | X / N | 🟢/🟡/🔴 |

Thresholds:

• First-shot: 🟢 >70 / 🟡 40–70 / 🔴 <40
• Scope growth: 🟢 <15 / 🟡 15–40 / 🔴 >40
• Replan rate: 🟢 <20 / 🟡 20–50 / 🔴 >50

Avg severity guidance:

• 🟢 <25
• 🟡 25–50
• 🔴 >50

Note: avg severity is an aggregate health signal, not the same as per-session severity bands.

Then add a short narrative summary of what is going well, what is breaking down, and whether the main issue is prompt quality, repo fragility, workflow discipline, or validation churn.

Root Cause Breakdown

| Root Cause | Count | % | Notes | |:---|:---|:---|:---|

Prompt Sufficiency Analysis

• common traits of high-sufficiency prompts
• common missing inputs in low-sufficiency prompts
• which missing prompt ingredients correlate most with replanning or abandonment

Scope Change Analysis

Separate:

• Human-added scope
• Necessary discovered scope
• Agent-introduced scope

Rework Shape Analysis

Summarize the main failure patterns across sessions.

Friction Hotspots

First-Shot Successes

List the cleanest sessions and extract what made them work.

Non-Obvious Findings

List 3–7 evidence-backed findings with confidence.

Severity Triage

List the highest-severity sessions and say whether the best intervention is:

• prompt improvement
• scope discipline
• targeted skill/workflow
• repo refactor / architecture cleanup
• validation/test harness improvement

Recommendations

For each recommendation, use:

• Observed pattern
• Likely cause
• Evidence
• Change to make
• Expected benefit
• Confidence

Per-Conversation Breakdown

| # | Title | Intent | Duration | Scope Δ | Plan Revs | Task Revs | Root Cause | Rework Shape | Severity | Complete? | |:---|:---|:---|:---|:---|:---|:---|:---|:---|:---|:---|

---

Step 11: Optional Post-Analysis Improvements

If appropriate, also:

• update any local project-health or memory artifact (if present) with recurring failure modes and fragile subsystems
• generate prompt_improvement_tips.md from high-sufficiency / first-shot-success sessions
• suggest missing skills or workflows when the same subsystem or task sequence repeatedly causes struggle

Only recommend workflows/skills when the pattern appears repeatedly.

---

Final Output Standard

The workflow must produce:

1. metrics summary
2. root-cause diagnosis
3. prompt-sufficiency assessment
4. subsystem/friction map
5. severity triage and prioritization
6. evidence-backed recommendations
7. non-obvious findings

Prefer explicit uncertainty over fake precision.
