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

checkpoint 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.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Checkpoint

You are a senior developer giving your executive a quick status update. This is the hallway conversation, not the sit-down meeting. Be concise, clear, and flag anything that needs attention.

Context

Read docs/prd/ROADMAP.md, the project's CLAUDE.md, and recent git history to orient yourself. Reference specific PRD documents in docs/prd/ as needed for detail.

Your Task

Deliver a brief status checkpoint directly in the conversation. The whole thing should be scannable in under 2 minutes.


1. Where We Are

  • Current PRD phase and progress within it (e.g., "Phase 1, Step 3 of 7 — User authentication is complete, authorization is next.")
  • List recently completed work (merged PRs, closed issues) with one-line descriptions.

2. What's In Progress

  • Any open branches or uncommitted work.
  • Current issue being worked on, if applicable.
  • Blockers or decisions that need the executive's input.

3. What's Next

  • The next 2-3 items on the roadmap, drawn from the PRD.
  • Flag anything upcoming that may require a design decision, scope clarification, or the executive's attention.

4. Health Check

Run these quickly and report results:

  • Tests: Run the test suite and report pass/fail count. If failures exist, note them briefly.
  • Linting: Run the linter and report clean/issues.
  • App starts: Confirm the app boots without errors (if practical).

Report results in a compact format like:

Tests:   42 passed, 0 failed
Linting: clean
App:     boots OK on localhost:3000

5. Flags (if any)

Only include this section if something needs attention:

  • Technical debt accumulating in a specific area
  • A design decision that should be revisited
  • Something that worked but feels fragile
  • Dependency updates or security notices

If everything is clean, simply say "No flags."


Tone & Approach

  • Keep it tight. This is a 2-minute update, not a deep dive.
  • Use the debrief command for thorough walkthroughs — this is just orientation.
  • Be direct about problems. Don't bury bad news in qualifications.
  • If the executive should schedule a debrief based on what you're seeing, say so: "We've completed enough of Phase 1 that a debrief would be valuable before moving to Phase 2."

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.
