Delete the daemon state directory on kcap uninstall by realtonyyoung · Pull Request #1581 · kurrent-io/kcap

AI-2410 (no GitHub issue)

What & why

kcap uninstall deleted the config directory but not the daemons directory, which KCAP_CONFIG_DIR never moves. With the variable set, uninstall always left ~/.config/kcap/daemons behind, including consent.json, a record of granted permission. Uninstall now deletes DaemonStore.Directory from its own anchor and lists it in the printed plan.

Where to look

Like the account registry, the directory is deleted even with --keep-config, and kept when any earlier step failed, so a re-run can still find and stop what is running.

Verification

UninstallCommandTests 25/25 pass, including a new case that deletes the directory with and without --keep-config, and an assertion that it survives a failed unwire.

Summary by CodeRabbit

Bug Fixes
- Uninstall removes the default daemon state directory only when no earlier cleanup step has failed. This applies with or without --keep-config or --project.
- The directory is retained if it has been relocated, is a link, or a daemon or daemon command holds a lock. I/O or access errors are reported and cause uninstall to fail.
Documentation
- Clarified when the daemon state directory is removed and when it is retained.

KCAP_CONFIG_DIR never moves the daemons directory, so the config-dir delete missed it, leaving lock files and granted consent behind. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 Walkthrough

Uninstall now removes the default daemon state directory before config-directory and account-registry cleanup, but only if no earlier step failed. DaemonStore checks lock paths before deleting entries. Uninstall leaves relocated or linked directories untouched.

Changes: Uninstall cleanup

Layer / File(s)	Summary
Daemon store directory removal `src/Capacitor.Cli.Core/DaemonStore.cs`, `test/Capacitor.Cli.Core.Tests.Unit/DaemonStoreTests.cs`	`DaemonStore` exposes the default directory and adds `DeleteAll()`. It snapshots entries, checks recognized lock paths, removes snapshot entries, and removes the directory if empty. Tests cover successful removal, held locks, and symbolic links.
Uninstall directory cleanup `src/Capacitor.Cli/Commands/UninstallCommand.cs`, `test/Capacitor.Cli.Tests.Unit/Commands/UninstallCommandTests.cs`, `README.md`	The command identifies the default, unlinked daemon directory and calls `DeleteAll()` only when no earlier step failed. Tests and the README cover cleanup conditions, including `--keep-config`, symlinks, redirected stores, and earlier cleanup failure.

Merge Risk: ⚪ Minimal · up to 7d689

The change removes the default, unlinked daemon-state directory after earlier cleanup succeeds, while preserving it for held locks and failed prior steps. The available evidence supports merging after normal checks.

Security architecture risk: 🟡 Moderate · up to 7d689

Daemon cleanup can discard deny or prompt consent rules even when --keep-config preserves configuration. A later restart without prompt-based consent initialization can then allow launches previously restricted by those rules. This requires an operator-triggered uninstall and subsequent restart; prompt-initialized boots avoid that outcome.

Retained concerns

Medium · security · inferred: The new cleanup removes consent.json even with --keep-config. Previously retained deny or prompt policy can therefore disappear while configuration remains. On a subsequent boot without consent seeding, the existing missing-file fallback permits server-driven launches. Cleanup can also remove consent before a later deletion failure preserves configuration. Prompt-seeded boots prevent this downgrade; applicability across all restart and reinstall routes remains unestablished.

Security review details

Security Blast Radius

observed — The new deletion targets the invoking user's default daemon-state directory across daemon names, not only the selected configuration profile. The caller excludes relocated directories and linked daemon roots or immediate parents. This is local filesystem authority; the conditional downstream concern affects server-driven launch consent.

Security Findings and Attack Paths

inferred — The conditional path is operator uninstall with retained configuration, deletion of restrictive consent, subsequent unseeded daemon boot, then a server-mediated launch request evaluated under Allow. It is not a demonstrated authentication bypass or remote ability to invoke uninstall. The missing-policy fallback predates this PR; newly deleting consent under --keep-config creates the changed exposure.

Trust Boundaries and Controls

observed — The destructive phase is behind user confirmation or --yes, default-path ownership checks, earlier-step success, root-link refusal, and candidate-lock acquisition. Snapshot links are removed themselves rather than followed. These controls constrain filesystem deletion but do not preserve restrictive consent after an authorized reset.

Resilience and Maintainability Implications

inferred — Failure propagation preserves configuration and account metadata for retry, but that retention is not equivalent to preserving daemon policy: consent can already have been deleted when a later cleanup operation fails. Recovery must therefore account for policy initialization as well as remaining files.

Hardening Proposals

proposed — Make consent reset distinguishable from a legacy missing policy, so retained-configuration restarts require fresh consent or initialize to prompt rather than inheriting Allow. Apply that recovery contract to interrupted cleanup as well as successful --keep-config uninstall.

Remove daemon state during kcap uninstall

🐞 Bug fix 🧪 Tests 🕐 10-20 Minutes

AI Description

• Delete daemon state independently of the config directory, including when --keep-config is set.
• Show daemon-state removal in the uninstall plan and preserve it if earlier steps fail.
• Test successful removal and preservation after a failed account unwire.

High-Level Assessment

Deleting DaemonStore.Directory as a separate, final cleanup step is appropriate because KCAP_CONFIG_DIR does not relocate it. Folding it into config deletion would miss the directory in some installations and would incorrectly spare it under --keep-config.

3. ~~A new daemon can outlive its lock~~ ✓ Resolved

Description

DeleteName opens the per-name lock with FileOptions.DeleteOnClose before deleting the other
files, so on Unix its locked inode can lose its pathname while cleanup is still running. A
concurrent daemon start can create and lock a new file at that pathname, after which cleanup can
remove the new daemon's PID, markers, and state.

8. ~~Uninstall guide promises a skipped lock guard~~ ✓ Resolved

Description

The README says uninstall keeps the daemon state directory whole while a daemon command holds a
lock, but the default config-directory deletion runs before DeleteAll() and recursively removes
that directory. With KCAP_CONFIG_DIR unset and a held .start lock but no PID file, daemon stop
finds no running daemon, so uninstall can remove the held lock without reaching the new guard.

Code

README.md[2457]

+`uninstall` covers every supported agent: it stops running daemons and watcher processes, strips kcap entries from user-level Claude Code, Codex CLI, Cursor, and Copilot CLI hook files (preserving any non-kcap entries), deletes the Pi extensions (`~/.pi/agent/extensions/kcap.ts` + the `kcap-mcp.ts` bridge) and strips kcap's block from `~/.pi/agent/AGENTS.md`, deletes the OpenCode plugin (`~/.config/opencode/plugins/kcap.ts`), removes the kcap capture plugin from Antigravity's `~/.gemini/config/plugins/kcap/`, removes agent skills under `~/.agents/skills/` (plus the legacy `~/.codex/skills/kcap-*` folders), removes the `kcap` git hook from `~/.gitconfig`, and deletes `~/.config/kcap/`. Every registered vendor account (see `kcap accounts`) is unwired too, and the account registry (`~/.config/kcap/accounts/`) and the daemon state directory (`~/.config/kcap/daemons/`, which `KCAP_CONFIG_DIR` never moves; kept whole while a daemon or daemon command still holds one of its locks, and left alone when `KCAP_DAEMONS_DIR` moved it or it is a link) are deleted last, only when no step failed — neither `--keep-config` nor `--project` spares them. A registry kcap could not read or lock is kept and the uninstall reported incomplete, since it is the only record of which accounts still record; check them with `kcap accounts`, then re-run `kcap uninstall`.

link to an accessible external file follows it, so closing the acquired handle can delete that file
even though uninstall checked the daemon directory itself for links.

Code

src/Capacitor.Cli.Core/DaemonStore.cs[R139-142]

+        var locks = entries
+            .Where(e => System.IO.File.Exists(e) && LockExtensions.Contains(Path.GetExtension(e).TrimStart('.')))
+            .Concat(entries.Where(System.IO.Directory.Exists).Select(d => File(Path.GetFileName(d), LockExtension)))

11. ~~A dangling link blocks state cleanup~~ ✓ Resolved

Description

DeleteAll snapshots a dangling child symlink but skips it because both Directory.Exists and
File.Exists return false for its missing target. If one is present, the final enumeration still
finds it, so uninstall leaves the daemon directory behind and reports a lock-use failure even when
no lock is held.

Code

12. ~~A failed cleanup still deletes lock files~~ ✓ Resolved

Description

DeleteAll opens each lock with DeleteOnClose, then returns when a later lock cannot be acquired;
its finally block deletes the locks it already acquired. If an unlocked entry precedes a busy one,
uninstall reports failure but leaves the earlier entry's PID and state without its lock file.

14. ~~A running daemon survives a successful uninstall~~ ✓ Resolved

DeleteName silently skips a name whose lock it cannot acquire, and UninstallCommand treats the

Remove only the daemon store's own entries, and none a daemon holds

KCAP_DAEMONS_DIR can name a shared directory, and unlinking a held lock lets the next start take a second lock on a fresh file. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Clean only the default daemons directory, locking each name first

003c27e

A directory KCAP_DAEMONS_DIR moved may be shared, and a name with no lock file could otherwise gain a starting daemon mid-delete. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Delete the daemons directory whole, under every lock it holds

2039a83

A held daemon, start or service lock now keeps the whole directory, and state with no daemon file beside it goes too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Never follow a link or drop a lock when daemon cleanup stops

f2d78d9

A cleanup refused by a held lock now leaves every lock file, a link inside the directory is removed rather than followed, and a linked kcap/ is refused. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
