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

brag-sheet 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 4d 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.

Brag Sheet — Work Impact Writer

Turn engineering work into evidence-backed impact statements for performance reviews, self-reviews, promotion packets, and weekly updates. Uniquely mines Copilot CLI session logs, git history, and PRs to reconstruct forgotten work.

USE FOR: "brag", "log work", "what did I do", "backfill", "performance review", "self-review", "promo packet", "weekly update", "status report", "write impact statement", "what did I ship", "I forgot to log my work", "review prep", "accomplishments" DO NOT USE FOR: project management, sprint planning, time tracking, ticket creation

Quick Start

User wants... Mode Output
Log one accomplishment Capture 1 impact-first entry
"What did I do last week?" Backfill Entries grouped by week, mined from git/PRs/sessions
Prep for review or promo Review Pack Entries grouped by impact theme + STAR narratives

Agent Behavior Rules

  1. DO confirm the time range and scope before scanning sources. Don't assume "last week" — ask.
  2. DO check which tools are available (save_to_brag_sheet, git, gh) before choosing a workflow.
  3. DO always include all three parts: action → result → evidence. If evidence is missing, write (evidence needed) — never silently omit.
  4. DO show drafted entries to the user before saving. Never auto-save without confirmation.
  5. DO group related commits into a single entry. Ten commits on the same feature = one entry.
  6. DO preserve the user's voice. Reframe for impact, but don't invent accomplishments or inflate scope.
  7. DO NOT fabricate metrics, team sizes, or impact numbers. If the user doesn't provide a number, don't invent one.
  8. DO NOT write entries for work the user only described verbally without verifying. Ask: "Did this ship? Is there a PR or doc I can reference?"
  9. DO NOT skip the backfill scan steps or draft entries before scanning is complete.
  10. DO NOT pad weak periods with trivial entries. An honest gap is better than inflated fluff.

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.
