Tapedeck

Obsidian plugin importing agent transcripts (Claude Code, ChatGPT/Codex, Pi .jsonl) as readable, re-importable notes, with a tape rack sidebar · community.obsidian.md ↗

How we tested

Method: Desktop install on the Linux box: reused the extracted official Obsidian 1.14.4 AppImage under a scratch dir. Fresh vault a scratch dir with Tapedeck 0.1.3 release assets in .obsidian/plugins/tapedeck. Obsidian ran with HOME=a scratch dir so the default shelves (~/.claude/projects, ~/.codex/sessions, ~/.pi/agent/sessions) held only synthetic data: the repo fixtures plus my own samples, and no real transcripts on the box were read. Launch flags: separate --user-data-dir, --no-sandbox, SwiftShader GL flags, --remote-debugging-port. Restricted Mode was turned off via app.plugins.setEnable(true). Commands ran via app.commands.executeCommandById over CDP Runtime.evaluate, filling the plugin's own modals (path field, shelf suggester, tape picker buttons) through the DOM. Notes were checked on disk, CDP Network/console events were captured, main.js was grepped, and screenshots were taken with python mss. No accounts or credentials; the tokens are fake..

Test log (from our notes)

What works

  • Installed from GitHub release 0.1.3 into a fresh vault on Obsidian 1.14.4 (Linux AppImage)
  • loads once Restricted Mode is off
  • and registers 4 commands (import-session-file
  • import-from-shelves
  • reimport-current-transcript
  • open-tape-rack). Everything was driven through those commands and their modals via CDP
  • no account needed. T1 (UI one-off import
  • my synthetic Claude Code JSONL with German/CJK/Arabic/emoji and a failed Bash call): wrote Transcripts/<date> claude-code <title>.md with correct frontmatter (harness
  • model
  • session_id
  • cwd shown as ~
  • resume command). Unicode was intact, UTC timestamps were converted to local PDT, Write became a diff and the failed Bash a [!failure] callout
  • and the fake ghp_/AKIA tokens became [REDACTED]. T2 (Import from tape shelves -> All enabled shelves): the picker listed 4 tapes with the correct agent emoji (Claude/Codex/Pi auto-detected)
  • marked the already imported one '⏪ in vault'
  • and 'Select all 4' -> 'Import 4 tapes' wrote one note each for the repo's Claude Code, Codex and Pi fixtures. Codex apply_patch became a diff, Pi's abandoned branch was hidden by default and its compaction became an [!abstract] callout. T3 (re-import): after I appended 2 turns to the session and set project by hand, Re-import current transcript updated the same note ('⏪ Updated…'): still 4 notes
  • created kept
  • updated added
  • project kept
  • new turns present. Importing the same session again via one-off path also updated the existing note (no duplicate). T4 (edge cases): empty
  • malformed and unknown-format JSONL each gave a clean notice '<name> does not look like a Claude Code, Codex
  • or Pi session' and wrote no note. A missing path gave an ENOENT notice. A Claude file with a corrupt middle line and a truncated last line imported with the bad lines skipped. A 1.85 MB, 3,000-message session imported to a 984 KB note with all 1,500 user + 1,500 assistant turns
  • a repeat import (update) took ~0.6 s. Tape rack sidebar listed the tapes grouped by project with in-vault badges. No console errors or exceptions across all runs. Session files were not modified (sha256 unchanged).

What breaks

  • '⏪ Re-import current transcript' fails on a note imported from a one-off file outside the shelves: notice '⏹️ Tapedeck: No Claude Code session file for <session_id>'. It looks the session up on the shelves only
  • re-running Import session file with the path works. Corrupt/truncated lines inside an otherwise valid session are dropped silently
  • with no warning in the note or notice. Picker/rack rows show the session file's modification time (2026-10-18 16:22 for fixtures copied today)
  • not the session date (2026-01-15) that the README example implies. Claude Code Edit diff headers have a doubled slash ('a//home/sample/...') when cwd isn't under home (cosmetic). machine property records the real hostname by default (documented
  • can be turned off). Agent friction: a new vault opens in Restricted Mode with a 'Do you trust the author of this vault?' modal
  • clicking 'Trust author' through CDP left the renderer unresponsive once
  • and Obsidian had to be restarted (plugin state persisted). Desktop only (isDesktopOnly true).

Release claims checked

  • verified Imports Claude Code, ChatGPT/Codex and Pi sessions; auto-detects which agent wrote a file (T1/T2: repo fixtures for all three plus my own Claude sample, imported via one-off path (auto-detect) and via shelves)
  • verified Re-importing finds the note by session_id: no duplicates; keeps created and project, adds updated (T3: note count stayed 4; created unchanged, updated added, manual project 'my-manual-project' kept)
  • verified Makes no network requests (main.js 0.1.3 has no fetch/XMLHttpRequest/requestUrl/WebSocket/sendBeacon/http(s)/net/child_process (only node:fs, fs/promises, os, path, crypto, obsidian); the only URLs are JSON-schema IDs. CDP Network logged only app:// and data: URIs during all imports.)
  • verified Writes only to your vault; never changes session files (Fixture sha256 unchanged after import; the only plugin writes outside notes were tape-cache.json in the plugin folder; files changed in the fake HOME were only Electron/fontconfig/NSS caches and my own appended sample)
  • verified Secret redaction (API keys, GitHub tokens, AWS keys) and home folder as ~ (Fake sk-ant-, ghp_ and AKIA strings became [REDACTED]; a scratch dir paths shown as ~ (best-effort per README; only these patterns tested))
  • verified Tool calls as folded callouts; edits/patches as diff; failed calls as failure callouts (Imported notes on disk)
  • verified Claude/Pi abandoned branches hidden unless 'Show abandoned branches' on (Pi fixture's 'Abandoned branch answer' absent from note with default settings (toggle not tested))
  • unverified Requires Obsidian 1.13.0+, desktop only (manifest minAppVersion 1.13.0 / isDesktopOnly true; only 1.14.4 tested)
  • still_broken Tape picker row shows date like '2026-01-15 09:00' (README example) (Rows showed file mtime (2026-10-18 16:22) for fixtures with session date 2026-01-15; may be intended (sorted by last change) but differs from the example)
  • unverified Images (freeze-frames) saved to vault and embedded (Not tested)
  • unverified Auto-import schedules, tape rack preview, worktree grouping, Codex session_index thread names (Not tested; tape rack listing only)

Quality score

3/5 — our subjective hands-on rating on a 1–5 scale.

Rescored 4 -> 3 by the coordinator under the 2026-10-18 rubric: the README documents 'Re-import current transcript' for any transcript note, but it fails for notes imported from a one-off file outside the shelves (a real bug in a documented path). The tester scored 4; every other tested task passed.
