prism-close

A command for closing a PRISM engagement, meaning a structured audit or research project managed across sessions and vendors.

In plain words
What is it for?
Use it to run the closing checks and create a plain-language report, plus an interactive workbook when the decision depends on numbers.
Why use it?
It checks for unfinished work, unresolved monitoring items, and missing returns before producing the final handover.

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

prism-close 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 2d 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.

What it actually says

Close the active PRISM engagement — run the Engagement-closure gate and hand over clean deliverables.

Optional Master pointer or closing focus (may be empty):

$ARGUMENTS

Then proceed:

  1. Locate the Master. Use an attached Master, the one in this project/repo, or the pointer above. If none can be found, run the SP-1 / missing-handoff recovery protocol in PRISM_core.md — do not regenerate the Master from memory.
  2. Load the framework if it is not already active: read PRISM_core.md (the Engagement-closure gate, §6.7, lives in the core).
  3. Run the closure gate — the three-layer close sweep. Verify everything dispatched has returned and converged, open Monitors are cleared, and What's next holds no pending work. Run the reconcile-at-close checklist. If the sweep finds unfinished work, halt and surface it — do not close over a gap.
  4. Produce the deliverables. Fetch reference/report-architecture.md and build the comprehensive plain-language report (the report skeleton + craft conventions); when the decision turns on numbers, add the interactive workbook cockpit so the audience can drive the model; apply the presentation house-style. For an external handoff, follow reference/external-share.md.
  5. Record closure in the Master and write a terminal What's next that marks the engagement closed.

This command is a Claude-Skill convenience for the closure phase; it changes no framework mechanic. Saying "close this engagement" in plain language is equivalent, and is the portable form on every other vendor.

Changes

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.
