Step 0 — Immediate Output

Before ANY tool calls, display this banner:

╔══════════════════════════════════════════════════════════════╗
║  PLAN-BUILD-RUN ► SESSION AUDIT                              ║
╚══════════════════════════════════════════════════════════════╝

Then proceed to Step 1.

$pbr-audit — Session Compliance & UX Review

You are running the audit skill. Your job is to analyze past Claude Code session logs for this project, checking PBR workflow compliance (STATE.md updates, hook firing, commit format, skill usage) and user experience quality (flow choice, friction, unmet expectations). You produce a comprehensive report document.

This skill uses parallel Task() delegation to analyze multiple sessions simultaneously, keeping main context lean.

---

Context Budget

Reference: skills/shared/context-budget.md for the universal orchestrator rules.

Additionally for this skill:

• Delegate ALL session analysis to audit agents — do NOT read JSONL files in main context
• Main context handles: argument parsing, session discovery, agent orchestration, report synthesis
• Target: main context stays under 20% utilization

---

Step 1 — Parse Arguments

Parse $ARGUMENTS for:

Argument	Default	Description
--from DATE	Start of today	Start of audit window (ISO date or natural language)
--to DATE	Now	End of audit window
--today	false	Shorthand for --from start of today --to now
--mode MODE	full	compliance = workflow only, ux = user experience only, full = both

Natural language parsing: Accept formats like:

• --today or just today
• --from 2026-02-21 or --from "yesterday"
• --from "3 days ago" or --from "last monday"
• A bare date like 02/21 implies --from 02/21 --to 02/21 (full day)
• A bare 3 implies last 3 days

If no arguments provided, default to --today --mode full.

Display the parsed time range to the user:

Audit window: {from} → {to}
Mode: {mode}

---

Step 2 — Discover Session Logs

Session JSONL files live at:

~/.claude/projects/{encoded-project-path}/*.jsonl

Where {encoded-project-path} encodes the project directory path (e.g., D:\Repos\plan-build-run → D--Repos-plan-build-run).

CRITICAL: Determine the correct encoded path for the current project by listing ~/.claude/projects/ and finding the directory that matches.

Use Bash to find sessions in the audit window:

find ~/.claude/projects/{encoded-path}/ -name "*.jsonl" -maxdepth 1 \
  -newermt "{from_datetime}" ! -newermt "{to_datetime}" | sort

For each session file found, also check for subagent logs:

ls ~/.claude/projects/{encoded-path}/{session-id}/agents/*.jsonl 2>/dev/null

Display discovery results:

Found {N} sessions in audit window:
  {session-id-1} ({size}, {date})
  {session-id-2} ({size}, {date})
  ...

If no sessions found, display an error and exit:

╔══════════════════════════════════════════════════════════════╗
║  ERROR                                                       ║
╚══════════════════════════════════════════════════════════════╝

No session logs found between {from} and {to}.
Check: ~/.claude/projects/{encoded-path}/

---

Step 3 — Discover Git Activity

In parallel with session analysis (Step 4), gather git commit data for the audit window:

git log --since="{from_iso}" --until="{to_iso}" --format="%h %s %an %ai" --all

Check for:

• Conventional commit format violations
• Forbidden Co-Authored-By lines
• Release-please automated commits

This data feeds into the final report synthesis.

---

Step 4 — Spawn Audit Agents

CRITICAL: Spawn one pbr:audit agent per session, ALL in parallel. Do NOT analyze sessions sequentially.

For each session:

Task({
  subagent_type: "pbr:audit",
  prompt: "<files_to_read>
    CRITICAL: Read these files BEFORE any other action:
    1. {absolute_path_to_session.jsonl} — session log to analyze
    2. {subagent log paths, if any} — subagent session logs
  </files_to_read>
  <audit_assignment>
    Session JSONL: {absolute_path_to_session.jsonl}
    Subagent logs: {list of subagent jsonl paths, or 'none'}
    Audit mode: {mode}
    Output path: DO NOT write to disk — return findings inline.

    Analyze this session for PBR workflow compliance and/or UX quality
    per your audit checklists. Return your full findings as structured
    markdown in your response.
  </audit_assignment>"
})

Also spawn a git analysis agent (can use a Bash agent or general-purpose):

Task({
  subagent_type: "Bash",
  model: "haiku",
  prompt: "Run these git commands in {project_dir}:
    1. git log --since='{from}' --until='{to}' --format='%h|%s|%an|%ai' --all
    2. git log --since='{from}' --until='{to}' --all --format='%B' | grep -i 'co-authored-by' || echo 'None found'
    Report: all commits, any format violations against pattern {type}({scope}): {desc}, any co-author lines."
})

Display progress:

◐ Analyzing {N} sessions in parallel...

---

Step 5 — Collect and Synthesize

As agents complete, check each audit agent's Task() output for ## AUDIT COMPLETE. If the marker is absent, mark that session as "analysis failed" in the synthesis and skip its findings — do not treat incomplete output as valid analysis. Log: ⚠ Session {id}: audit agent did not return completion marker — skipping.

Wait for all agents before proceeding.

Synthesize across all sessions:

5a. Executive Summary

• Total sessions, total commits, releases
• Overall compliance: how many sessions passed/failed
• Headline finding (the most important issue)

5b. Per-Session Summary Table

Session	Duration	Commands	Compliance	UX Rating

5c. Cross-Session Patterns

• Recurring issues (e.g., STATE.md never read across multiple sessions)
• Hook coverage gaps
• Common flow mistakes

5d. Consolidated Findings

Merge and deduplicate findings across sessions. Categorize by severity:

• CRITICAL: Workflow bypassed despite user requests, hooks not firing
• HIGH: State files not consulted, missing artifacts
• MEDIUM: Suboptimal flow choice, missing feedback
• LOW: Minor ceremony issues, informational

5e. Recommendations

Prioritize as:

• Immediate: Fix in next session
• Short-term: Fix in next sprint/milestone
• Medium-term: Architectural improvements

---

Step 6 — Write Report

CRITICAL: Write the full report to disk. Do NOT just display it inline.

Write to: .planning/audits/{YYYY-MM-DD}-session-audit.md

Create .planning/audits/ directory if it doesn't exist.

The report should follow this structure:

# PBR Session Audit Report — {date range}

**Audit Period:** {from} – {to}
**Sessions Analyzed:** {N}
**Commits:** {N}
**Mode:** {mode}

---

## Executive Summary
{2-3 sentence overview}

## Session Summary
{per-session table}

## Detailed Session Analysis
{per-session findings}

## Git Activity
{commit summary, format compliance}

## Cross-Session Patterns
{recurring issues}

## Consolidated Findings
### Critical
### High
### Medium
### Low

## Recommendations
### Immediate
### Short-Term
### Medium-Term

---
*Generated by $pbr-audit on {date}*

---

Step 6b — Spot-Check Artifacts

Before displaying results, verify the report landed on disk:

1. Glob .planning/audits/{YYYY-MM-DD}-session-audit.md to confirm the file exists
2. If missing: re-attempt the write (Step 6). If still missing, display an error and include findings inline instead.

---

Step 7 — Display Summary

After writing the report, display inline (keep it concise — the full report is on disk):

╔══════════════════════════════════════════════════════════════╗
║  PLAN-BUILD-RUN ► AUDIT COMPLETE ✓                           ║
╚══════════════════════════════════════════════════════════════╝

{N} sessions analyzed, {N} commits reviewed

Compliance: {X}/{N} sessions passed
UX Rating:  {average or per-session ratings}

Top findings:
  1. {headline finding 1}
  2. {headline finding 2}
  3. {headline finding 3}

Full report: .planning/audits/{filename}


╔══════════════════════════════════════════════════════════════╗
║  ▶ NEXT UP                                                   ║
╚══════════════════════════════════════════════════════════════╝

{Smart routing based on findings:}
- If critical issues found: **Fix workflow** → `$pbr-quick`
- If todos identified: **Create todos** → `$pbr-todo add "{description}"`
- Default: **See project status** → `$pbr-status`

<sub>`/clear` first → fresh context window</sub>

Error Handling

Agent fails to analyze a session

If an audit agent fails:

⚠ Failed to analyze session {id}: {error}
Continuing with remaining {N-1} sessions.

Include a note in the final report that session was skipped.

No sessions found

Display error (Step 2) and exit gracefully.

Very large session files (>5MB)

Warn the agent to sample rather than read the full log:

Note: Session {id} is {size}MB. Sampling key sections (first 200 lines, last 200 lines, user messages, hook events).

---

Anti-Patterns

Reference: skills/shared/universal-anti-patterns.md for rules that apply to ALL skills.

Additionally for this skill:

1. DO NOT read JSONL files in main context — always delegate to audit agents
2. DO NOT display the full report inline — write to disk, show summary
3. DO NOT analyze sessions sequentially — spawn all agents in parallel
4. DO NOT report findings without evidence (line numbers, timestamps, quotes)
5. DO NOT judge explore sessions for missing STATE.md updates (explore is read-only)
6. DO NOT flag release-please/merge commits as format violations
7. DO NOT fabricate UX ratings — base them on concrete evidence (user repetitions, escalations, course-corrections)
8. DO NOT exceed 5 headline findings in the inline summary — full details go in the report file
