Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

session-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

STOP -- DO NOT READ THIS FILE. You are already reading it. This prompt was injected into your context by Claude Code's plugin system. Begin executing Step 1 immediately.

/pbr:session-report -- Post-Session Summary

References: @references/ui-brand.md

You are the orchestrator for /pbr:session-report. This read-only skill generates a summary of work performed during the current session. By default it displays the report without writing files.

Step 0 -- Immediate Output

Before ANY tool calls, display this banner:

+--------------------------------------------------------------+
|  PLAN-BUILD-RUN > SESSION REPORT                             |
+--------------------------------------------------------------+

Then proceed to Step 1.

Step 1: Parse Arguments

  1. Parse $ARGUMENTS for optional flags:
    • --since <time> -- git log time filter (default: "8 hours ago")
    • --save -- write report to .planning/reports/session-{date}.md
  2. Compute the time window for analysis

Step 2: Gather Session Data

  1. Read .planning/STATE.md for current position (phase, plan, status)
  2. Count commits in time window:
    git log --oneline --since="{since}" --format="%H %s"
    
  3. Get file change stats:
    git diff --stat HEAD~{commit_count}..HEAD 2>/dev/null || git diff --stat --since="{since}"
    
  4. Read SUMMARY-*.md files modified during this session:
    git log --since="{since}" --diff-filter=AM --name-only --format="" -- ".planning/phases/*/SUMMARY-*.md"
    
    Extract status and key outcomes from each.
  5. Check for VERIFICATION.md updates:
    git log --since="{since}" --diff-filter=AM --name-only --format="" -- ".planning/phases/*/VERIFICATION.md"
    
  6. Check test results if a test command was run recently:
    git log --since="{since}" --oneline --grep="test"
    

Step 3: Compute Metrics

  1. Commit breakdown: count commits by type (feat, fix, refactor, test, docs, chore)
  2. File breakdown: count files by directory/category
  3. Phase progress: compare STATE.md current plan vs total plans
  4. Velocity: commits per hour estimate

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
