winui-session-report
Analyze the current or a recent agent session (GitHub Copilot CLI or Claude Code) and generate a diagnostic report. Use when asking for session feedback, debugging agent behavior, or reviewing what happened during a build session.
Skill body
Session Analysis Report
Generate a diagnostic report for an agent session by running the Analyze-Session.ps1 script included with this skill. The script auto-detects whether the current session was produced by GitHub Copilot CLI or Claude Code from environment variables and on-disk file format, and dispatches to the appropriate parser. If neither harness can be detected, the script exits with a clear error.
Privacy and sensitivity — surface this guidance to the user
Analyze-Session.ps1 always:
- Embeds a “Privacy and sensitivity” section at the top of the generated
session-report.md(right above the Overview table), and - Prints a yellow PRIVACY NOTICE banner to the console when it finishes writing the file.
You (the agent) must surface this guidance to the user in your response — do not let it stay buried in script output the user might not have read. When you finish running the script and reporting the findings, include a short privacy reminder in your reply to the user, in plain second-person language. Use this template, adapting wording as needed:
⚠️ Heads-up before you share
session-report.md— this file contains your unredacted session transcript: file contents and paths the agent read or edited, your prompts verbatim (including any secrets you may have pasted), tool output, environment values, and local paths underC:\Users\<you>\…. You’re responsible for what you share — please open the file in your editor and read it end-to-end before attaching it to a public issue, posting it in chat, or sending it outside your organization. Redact anything sensitive. If you only need to share the high-level metrics, ask me to summarize the file instead of attaching it.
If the user only wants the high-level metrics (turn counts, skill usage, build success rate) without the per-turn detail, summarize the report and share the summary instead of the file — and tell the user that’s what you’re doing so they don’t have to read it themselves to confirm.
Steps
- Run the analysis script to generate the report:
# Analyze the most recent session (auto-detects harness) and save report
.\Analyze-Session.ps1 -OutputFile session-report.md
# Or analyze a specific session by ID (searched in both harness locations)
.\Analyze-Session.ps1 -SessionId "<session-id>" -OutputFile session-report.md
# Or analyze a transcript file directly (format sniffed from content)
.\Analyze-Session.ps1 -EventsFile <path-to-transcript.jsonl> -OutputFile session-report.md
# Force a specific format if auto-detection picks the wrong harness
.\Analyze-Session.ps1 -Format ClaudeCode -OutputFile session-report.md
# Skip subagent transcripts (Claude Code only) for a parent-only view
.\Analyze-Session.ps1 -SkipSubagents -OutputFile session-report.md
Detection rules:
- The current session is preferred when an explicit ID is available:
COPILOT_AGENT_SESSION_ID(Copilot CLI) orCLAUDE_SESSION_ID(Claude Code) take priority over “most recently modified” so a parallel session in another terminal can’t shadow the one the skill was invoked from. - Environment first:
CLAUDECODE=1orCLAUDE_CODE_ENTRYPOINT-> Claude Code;COPILOT_*env vars -> Copilot. - For Claude Code, the most-recent JSONL whose
cwdmatches the current working directory is preferred. - For an explicit
-EventsFile, the format is sniffed from the first events. - If neither harness is detected, the script exits with a non-zero status and a message naming both supported locations.
- Review the generated report — read
session-report.mdand summarize key findings for the user:- How many turns, how long, token usage
- What skills were loaded and when
- Build success/failure pattern
- Any stuck patterns or tooling issues detected
- Add your own observations — append a section to the report with any additional context:
- Was the final app working? What’s missing?
- Quality assessment of the generated code
- Suggestions specific to what went wrong
- Include any tooling improvements or recommendations based on the analysis.
- Are there rules that need to be added to the Roslyn analyzer to prevent common mistakes detected during the session?
- Were there bugs or issues with winapp run or the BuildAndRun.ps1 script?
- Are there features that could be added to lower the number of turns required to complete a task?
What the Report Covers
| Section | Details |
|---|---|
| Overview | Harness, session ID, model, duration, turns, tokens (incl. cache tokens for Claude Code) |
| Prompt | The original user request |
| Turn Breakdown | Turns and tokens by category (building, coding, exploring, subagent dispatch, etc.) |
| Skills | Which were invoked and when, including from inside subagent transcripts |
| Subagents | (Claude Code only) Per-agent breakdown of dispatched subagents and their work |
| Build Analysis | Build attempts, failures, errors, whether BuildAndRun.ps1 was used |
| Stuck Patterns | Build loops, repeated file reads, obj/ clean cycles |
| Tooling Issues | Auto-detected improvement opportunities |
| Turn Detail | Every turn with tools used and errors flagged, parent and subagent transcripts shown separately |
When to Use
- When the user asks for a session report to understand what happened during an agent session.
