Core

PRISM framework loader

This Skill loads PRISM — the canonical operating framework for structured, multi-session, multi-vendor LLM-orchestrated audit and research. The framework is decomposed into a lean always-loaded core plus on-demand bundles; load the core first, fetch a bundle only when the work in front of you needs it.

When triggered

1. Read PRISM_core.md in full before acting — it is the operating core (operating model and architecture, the Execution Envelope / Self-check / Output triple contract, the prompt-package engine, the context-pressure framework including the M5 bands and the in-core recovery floor, the §{section.lens-schema-what-orchestration-consumes} lens schema, Monitors M1–M12, Standing Principles, filename conventions, the atomic-prompt template, the operator-hint catalog, the engagement-closure gate, and the phase → bundle manifest). Phase-scoped mechanics (Setup, currency, continuity, corpus-access) are on-demand bundles — see step 5.
2. Run the SP-13 substrate self-check (Standing Principle SP-13, in the core's section 10.1.3): declare your model identity and confirm you are Claude, Opus-class / flagship tier (a capability floor — version-agnostic, latest by default). Halt and ask the operator on mismatch or cannot-determine.
3. Run M1 (Missing Inputs) and M2 (Version Drift): verify the canonical attachments are present (Master, subject brief, and a Prompt Strategy if separate) and that the Master version matches what the last What's next predicted. Halt at HIGH severity on a missing required artifact or a version mismatch.
4. Proceed per the Master's What's next artifact, or per the operator's declared next action.
5. Load the phase bundle for the role you occupy. The core is lean; phase-, seam-, and condition-scoped mechanics are fetched on demand per the core's phase → bundle manifest (section 3.7.6). Run the visible self-check and fetch:
   • Setup / P0 (no Master yet, or the operator initiates an engagement) → reference/setup.md (probes, three-layer readiness, Setup-artifact procedures).
   • Update session / the session-open currency check → reference/currency.md.
   • Resume with a missing or abnormal handoff, or M5 band 🟠/🔴 → reference/continuity.md (the in-core recovery floor stays resident; the full migration / recovery procedure is in the bundle).
   • A pass classified corpus-access → reference/corpus-access.md. Each gutted area carries a fail-loud in-core stub — operating without the required bundle is detectable, not a silent gap.

Front-door carve-out (before the halts). If the operator's opening message is a bare orientation question ("how do I use PRISM", "where do I start", "what is this") with no engagement context — no Master, no subject — answer with a 30-second orientation and an offer to begin before the M1 / M2 halts in step 3; an orientation question is not an engagement open. SP-13 (step 2) still applies. This mirrors the core's front-door behavior; /prism-help renders the same orientation, and beginning an engagement hands off to /prism-start.

On-demand bundles — fetch only when the task needs them

Read these with the file tool at the moment a task calls for them; they are not resident until you open them.

• lens/PRISM_lens_library.md — the Lens Library v0.16 (canonical catalog). Fetch at Setup and whenever Probe 1 grades the strategy against lenses.
• reference/templates.md — paste-ready Setup and dispatch blocks (Envelope, Self-check, Output, Decision brief, Stakeholder register, Claim inventory, Jurisdiction map, Dispatch register). Fetch when producing one of these artifacts.
• reference/setup.md — the Setup-phase mechanics: three-layer readiness, the seven probes (P1–P7), Setup-artifact procedures, strategy stability, onboarding, Library-reference-at-Setup, the Scope-Integrity Test, specialist-pass promotion, and the Claude-Project-as-Setup recommendation. Fetch at a Setup session / the P0 boundary.
• reference/currency.md — point-refresh, the Update session, and the session-open currency check. Fetch for an Update session or when the currency-check-at-open fires.
• reference/continuity.md — the migration handoff format, failsafe recovery, defensive migration at natural seams, and cold-open missing-handoff recovery. Fetch at a resume / context-seam, or when M5 reads 🟠/🔴.
• reference/corpus-access.md — the corpus-access dispatch (the investigation-posture Envelope for a targeted external-corpus lookup). Fetch when the dispatch-builder classifies a pass as corpus-access.
• reference/modes-and-surfaces.md — the Cowork capability surface and the repo_backed persistence mechanics. Fetch when a non-default orchestration surface or persistence value is in play.
• reference/lanes-ui.md — the lanes / roles model, the PRISM Desk and PRISM Meta standing lanes, the PRISM UI, and Setup onboarding. Fetch when lanes / Desk / UI / onboarding work is in front of you.
• reference/dispatch-conventions.md — the promoted dispatch convention set (§A–H), the promotion map, the canonical execution-paste model, and the digest-preimage pin. Fetch when building or converging a dispatch.
• reference/report-architecture.md — the comprehensive final report skeleton
  • craft conventions, the interactive workbook cockpit pattern, the presentation house-style, and the reconcile-at-close checklist. Fetch when building or closing an engagement deliverable.
• reference/external-share.md — one-repo-per-engagement, the de-coded share archive, share modes, the image-redaction procedure, and the read-the-repo-not-the-mirror canonical-source block. Fetch when preparing an external handoff.
• reference/provenance.md — spec→v2 source mapping, the decision-tag index, and the v1.x→v2 surface drift. Fetch when tracing a decision's rationale or origin.
• reference/glossary.md — the glossary. Fetch on an unfamiliar term.
• reference/worked-example.md — a worked example flow and the empirical calibration items. Fetch to see constructs flow in a real audit.
• reference/mobile-operator-guide.md — the mobile-operator survival guide.
• reference/vendor-parsing.md — vendor parsing observations.
• reference/parked-design-ideas.md — parked v2 design ideas (reference only).

Operating discipline

• Treat the core as authoritative. When the operator's request and the framework conflict, surface the conflict and ask — do not silently override the framework.
• Honour Standing Principles persistently. SP-9 in particular: silence is never consent. SP-1: never silently regenerate canonical artifacts.
• Write the Master and What's next at every orchestration turn-close, regardless of context band.
• Emit operator hints only when a cue applies to the specific dispatch — routine turns carry no hints.

What this Skill does NOT do

• Does not regenerate a missing Master from memory — it runs the SP-1 / missing-handoff recovery protocol.
• Does not silently substitute v1.10.4 mechanics — v2 supersedes v1.x; v1.10.4 projects stay on v1.10.4.
• Does not bypass operator ratification at the P0→P1 boundary.
• Does not auto-retry a failed dispatch — it surfaces re-dispatch as a candidate and the operator decides.
