@prismer/adapters-core

Shared utilities for Prismer PARA adapters. Consumed by:

• @prismer/claude-code-plugin (CC adapter, Task 3)
• @prismer/openclaw-channel (OpenClaw adapter, Task 4)

NOT published for external use — internal shared code to eliminate duplication between the two TS adapters.

Contributors: @prismer/wire resolves from the npm registry. npm install in this dir fails until @prismer/wire is published — use sdk/build/pack.sh --scope all + install.sh --local-artifacts for local dev.

Key Exports

PermissionLeaseManager

Tracks which skills own which PermissionRules. When a skill deactivates (agent.skill.deactivated), call revoke(skillName) to atomically remove its rules.

const leases = new PermissionLeaseManager();
leases.grant('review', [{ source: 'skill', behavior: 'allow', value: 'Read' }]);
leases.active();           // flat list of all leased rules
leases.revoke('review');   // returns the revoked rules
leases.clear();            // remove all

Event builders (event-builder.ts)

Pure constructors for the ~20 PARA events adapters commonly emit. Each validates via ParaEventSchema.parse() and throws ZodError on bad input.

import { makeToolPre, makeSessionStarted, makeRegisterEvent } from '@prismer/adapters-core';

const evt = makeToolPre({ callId: 'c1', tool: 'Bash', args: 'ls', riskTag: 'low' });

Normalizers (normalize.ts)

Coerce raw hook payloads into canonical types:

normalizeCallId(raw)               // UUIDv4 if absent
normalizeTimestamp(raw)            // ms epoch; accepts Date | ISO string | number
normalizeSessionId(raw, fallback?) // string; generates if absent
normalizeRiskTag(toolName, args)   // 'low' | 'mid' | 'high' heuristic

EventDispatcher

Routes validated PARA events to a transport sink. Validation failures invoke onError instead of throwing.

const dispatcher = new EventDispatcher((evt) => process.stdout.write(JSON.stringify(evt) + '\n'));
dispatcher.onError((err, evt) => console.error('[dispatcher] drop:', err.message));
await dispatcher.emit(evt);

Dependency Strategy

@prismer/wire is resolved via a local tarball (../wire/prismer-wire-0.1.0.tgz) because @prismer/[email protected] is not yet published to npm. Per project memory (feedback_npm_file_dep_silent_fail.md), file: path deps are avoided to prevent dangling symlinks at publish time; tarball deps are safe.
