The two hook bridges (dsh-hooks-claude, dsh-hooks-codex) would otherwise duplicate
the bulk of the protocol — Codex deliberately reimplements a SUBSET of the Claude
Code protocol (same hooks.json shape, exit-code/stdout contract, command-hook
model). This library holds the genuinely-identical primitives; each bridge owns
only what differs (per-event stdin payload, env/substitution, decision mapping).
New packages/hooks/ group; hook-protocol is a LIBRARY (no plugin, registers/injects
nothing):
- matcher: matchesMatcher(pattern, query, mode) — the one dialect axis collapsed to
a mode param (claude = literal-or-regex with pipe alternation; codex = always
unanchored regex). Match-all on absent/''/'*'; invalid regex matches nothing.
- codec: parseHookOutput(exit, stdout, stderr) → dialect-neutral HookOutput. Exit 0
→ lenient JSON; exit 2 → blocking error (stderr = reason, surfaced as
decision:'block'); other → non-blocking. Parses the CC superset
(continue/stopReason/decision/hookSpecificOutput.{permissionDecision,
additionalContext,updatedInput}/systemMessage); permissionDecision overrides the
legacy top-level decision.
- runner: runHook(bash, hook, opts, now) — runs a command hook via ctx.bash (stdin
payload + trusted-plugin env), honors timeoutSec, never throws (executor reject →
non-blocking-error HookOutput). Injected clock for testable durations.
- merge: mergeHookOutputs — most-restrictive fold (deny>ask>allow, sticky stop,
block reasons joined, context/system-messages accumulated).
- hook/* session events (declaration-merged into SessionEventMap, log-only like
compact/*) + appendHookInvoked/appendHookResult helpers.
updatedInput is parsed but NOT honored (deferred pre-tool-input-rewrite RFC); a
bridge logs+warns. 47 unit tests at per-file 100% (matcher per-mode, codec per
exit-code/field, runner plumbing w/ stub executor, merge precedence, hook/*
helpers). RFC: implemented/feature/2026-06-30-hook-protocol-lib.md.

Module dependency graph
Inter-package dependencies among the @deepseek-ai/dsh-* harness packages, derived from each package's peerDependencies (the canonical runtime-dependency signal). An edge a --> b means package a depends on package b. Names have the @deepseek-ai/dsh- prefix stripped.
