Vibe Replay already has Hermes support (provider-hermes, #421). This PR closes the remaining gaps so it matches the Hermes setup people actually run — multiple profiles — and cleans up a few tool-mapping blind spots.

Why

On this machine the default ~/.hermes/state.db only has legacy/cron sessions; the real work lives in ~/.hermes/profiles/codex/state.db (and mimo, backup). Today discovery only opens one DB (hermesDbPath()), so the dashboard shows 443 stale sessions and hides the 30 sessions in codex — including every session the reporter tried to replay. A few common Hermes tools also render as raw lowercase ids browser_navigate, cronjob instead of their viewer names.

Related: es617/claude-replay#32 (the same Hermes coverage was just added to claude-replay in parallel).

What changed

sqlite.ts — new hermesDbPaths() / openAllHermesDbs()

  • hermesDbPaths() returns the default DB plus every ~/.hermes/profiles/*/state.db that exists. Respects HERMES_HOME — when set, only that directory is used (mirrors Hermes itself).
  • openAllHermesDbs() opens each known DB via sql.js (WASM) with the same table-probe guard.

discover.ts — scan all DBs

  • discoverHermesSessions() now opens all DBs, calls listSessionsFromDb(db, dbPath) per-DB, dedups by sessionId, and re-sorts globally by last_activity_at. Each SessionInfo carries the correct marker path <dbPath>#session:<id> so the viewer links back to the right SQLite file, and a profile field for badge/grouping in the dashboard.
  • listSessionsFromDb now takes an optional dbPathOverride so per-DB marker paths are accurate.

parser.ts — profile-aware parse

  • New hintedDbPath() fast-path: marker paths like .../profiles/codex/state.db#session:ID already encode the right DB — use that before scanning all DBs. Clean open/close ownership: find the winner while handles are live, close all, then re-open the winning DB fresh and parse. No leaked WASM handles.

tool-mapping.ts — 10 more tools

  • Adds browser_navigate→BrowserNavigate, browser_click→BrowserClick, browser_type→BrowserType, browser_snapshot→BrowserSnapshot, browser_console→BrowserConsole, browser_scroll→BrowserScroll, browser_press→BrowserPress, browser_get_images→BrowserImages, cronjob→Cron, memory→Memory, codex→Codex so the transform's scene detection sees them with a first-class name. Matches the mapping already shipped in feat: add Hermes Agent support (export + live SQLite) es617/claude-replay#32's hermes.mjs.

How to test

On this machine hermesDbPaths() now returns four paths and discovery returns 473 sessions (was ~443) with the codex profile's 30 sessions now visible.

No breaking changes

Existing single-DB users (including HERMES_HOME setups) see identical behaviour — the new enumeration just additionally includes profiles when they exist. Existing tests that call listSessionsFromDb(db) without the new dbPathOverride arg still work via the default.

Summary by CodeRabbit

  • New Features

    • Added support for discovering sessions across the default Hermes database and profile-specific databases.
    • Session results now include the associated profile and database information.
    • Added recognition for browser, cron, memory, and Codex tools.
  • Improvements

    • Sessions are sorted by most recent activity.
    • Session discovery handles multiple databases more reliably and reports clearer database- or session-specific errors.
    • Improved support for custom HERMES_HOME locations.

📝 Walkthrough

Walkthrough

Hermes now discovers and parses sessions across default and profile databases. Session metadata includes the producing database path and optional profile label. Additional Hermes tool names map to canonical transform types.

Changes

Hermes multi-database session support

Layer / File(s) Summary
Database path discovery and opening
packages/provider-hermes/src/hermes/sqlite.ts
Hermes enumerates default and profile state.db files, opens available databases, and changes session ID prefix detection.
Multi-database session discovery
packages/provider-hermes/src/hermes/discover.ts
Session discovery scans all opened databases, removes duplicate session IDs, closes handles, sorts by activity, and attaches database and profile metadata.
Database-aware session parsing
packages/provider-hermes/src/hermes/parser.ts
Parsing probes hinted and discovered databases, cleans up handles, retries candidate paths, reopens the winning database, and records its path.

Hermes tool mappings

Layer / File(s) Summary
Canonical tool mappings
packages/provider-hermes/src/hermes/tool-mapping.ts
Browser, cron, memory, and Codex tool names now map to canonical transform types.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 4a396

Multi-profile discovery can currently associate replay data with the wrong database, while Windows paths and timestamp-based session IDs may be handled incorrectly. The PR is not merge-ready until the source-path bug and related edge cases are fixed.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Normalize the database path before extracting the profile.

join() produces \ separators on Windows. indexOf("/profiles/") then fails, so profile sessions have no profile label. Normalize with redactFilePath before matching the /profiles/ segment.

As per coding guidelines, normalize replay file paths to / for cross-platform display via redactFilePath.

Thanks for the PR — multi-profile Hermes discovery is exactly the right call, and the marker-path fast path is a nice touch. I pushed a few fixes to this branch to get it merge-ready (verified against real multi-profile data on my machine):

Fixes

  • sqlite.ts: restored the digit character classes in isHermesSessionId — the escaping was accidentally doubled (/^\\\\d{8}_/… matches a literal backslash, so every valid id returned false).
  • sqlite.ts: hermesDbPaths() previously treated any HERMES_HOME as a single-directory install. That's not how Hermes resolves things — I checked get_default_hermes_root() in Hermes itself: HERMES_HOME inside ~/.hermes is profile mode (root stays ~/.hermes, so profiles must still be scanned), and outside it, that path is the root and profiles live under <HERMES_HOME>/profiles/. The new hermesRootDir() mirrors that.
  • parser.ts: dataSourceInfo.sources now reports the DB that actually produced the session (parseSessionFromDb takes an explicit path) — the _dbPath lookup could never resolve, so profile sessions were misreported as coming from the default DB. Also dropped the redundant second candidate pass after openAllHermesDbs() already scanned everything fresh.
  • discover.ts: removed the undeclared profile field for now (no consumer yet) — let's add it properly through @vibe-replay/provider-contract when the dashboard grows a profile facet.
  • Tests: multi-profile discovery (merge/dedup/marker paths/global sort via a temp HERMES_HOME), an isHermesSessionId regression test, and a dataSourceInfo source-path test.
  • Docs: CLAUDE.md now documents multi-profile discovery plus one caveat worth knowing: sql.js reads raw file bytes and cannot replay un-checkpointed -wal frames, so sessions still sitting in the WAL of a long-running gateway stay invisible until Hermes checkpoints.

Verified locally on a machine with both a default DB and a live ru profile: discovery merges sessions from both DBs with correct per-DB marker paths and global newest-first ordering.

…-aware parse

- discover: scan all known Hermes DBs (default + every
  ~/.hermes/profiles/*/state.db), merging with dedup and timestamp
  sort. Respects HERMES_HOME when set. Previously only the default
  DB was read, so sessions in the active codex profile (and any
  named profile) were invisible in the dashboard.

- parser: openAllHermesDbs + hintedDbPath fast-path. Marker paths
  like .../profiles/codex/state.db#session:ID already carry the
  correct DB; use that before scanning all DBs. Handles both the
  discovered-session and --session flows.

- sqlite: new hermesDbPaths() / openAllHermesDbs() helpers; single-DB
  openHermesDb unchanged.

- tool-mapping: add browser_* (navigate/click/type/snapshot/console/
  scroll/press/get_images), cronjob, memory, and codex so the replay
  transform renders them with a first-class name.

Matches claude-replay Hermes support built in parallel:
  es617/claude-replay#32
- sqlite: restore digit character classes in isHermesSessionId
  (accidental over-escaping made every valid id fail to match)
- sqlite: mirror Hermes's get_default_hermes_root() in a new
  hermesRootDir(): HERMES_HOME inside ~/.hermes (profile mode) keeps
  scanning all profiles; Docker-style HERMES_HOME outside ~/.hermes
  scans <HERMES_HOME>/profiles/* instead of being treated as one dir
- parser: pass the producing dbPath into parseSessionFromDb so
  dataSourceInfo.sources names the right SQLite file for profile
  sessions (the _dbPath lookup never resolved)
- parser: drop the redundant second candidate pass after
  openAllHermesDbs already scanned every DB fresh
- discover: remove unused imports and the undeclared 'profile' field
  (no consumer yet; revisit alongside dashboard support)
- tests: multi-profile discovery merge/dedup/marker-path coverage,
  isHermesSessionId regression, dataSourceInfo source path
- docs: CLAUDE.md Hermes notes for multi-profile + WAL caveat

Thanks for the first contribution, @ebolamerican — and welcome! 🎉

Multi-profile discovery closes a real gap: on my own machine the default DB only had cron sessions while the actual work sat in profiles/ru/state.db, so this wasn't just theoretical. The marker-path fast path was a particularly nice touch.

I pushed a handful of fixes to your branch during review (detailed in my earlier comment) — most notably aligning HERMES_HOME semantics with Hermes's own get_default_hermes_root() and restoring an accidentally over-escaped regex. Nothing here should be surprising; all credit for the core design is yours.

Merged as a9517fb. Looking forward to more contributions!
