`resolveAllowedPath` resolved its input against the working directory without expanding a leading `~`, while `assertAllowedPath` expanded it. The two disagreed: a path such as `~/.codex/skills/caveman/SKILL.md` became `<workspace>/~/.codex/skills/caveman/SKILL.md` instead of resolving against the home directory. `open_workspace` advertises skill entrypoints as `~`-prefixed paths, so every skill read failed with ENOENT. The skill read fallback in `resolveReadPath` only runs when workspace path resolution throws, and the literal `~` path resolved silently inside the workspace, so the fallback never fired.

A rabbit checks a path at night,
It expands the tilde just right.
Home paths land where they belong,
Outside roots are turned along.
Tests keep watch, both near and far,
Then hop beneath a root-bound star.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep the outside-root test independent of HOME.
If homedir() is /workspace or a descendant, ~/file.txt resolves inside the allowed /workspace root, so this assertion fails. Derive both cwd and the allowed root from home; the old behavior will still resolve the literal ~ path inside that root.

open_workspaceadvertises skill entrypoints as~-prefixed paths, butresolveAllowedPathresolved its input against the working directory without expanding a leading~. A skill path like~/.codex/skills/caveman/SKILL.mdbecame<workspace-root>/~/.codex/skills/caveman/SKILL.md, so every skill read failed with ENOENT.assertAllowedPathalready expands home paths in its own body, so the two functions disagreed. Because the literal~path resolved silently inside the workspace, the skill read fallback inresolvePathnever ran — the fallback only fires when workspace path resolution throws.The default
agentDiris~/.codex, and~/.agents/skillsand~/.devspace/skillsare default discovery paths, so this affected every default skill location. I observed 27 failed~reads and 0 successes in a local server log before finding it; absolute paths work, which is why it is easy to miss when testing by hand.The fix expands the home path before resolving against the working directory, matching
assertAllowedPath. A~path outside the allowed roots now throws instead of resolving silently, which is what lets the skill fallback take over. The test updates the assertion that recorded the previous behavior.Verified with
pnpm typecheck, the full test suite (one unrelated failure:node-ptyis an optional dependency not installed here, and it fails the same way onmain), and an end-to-end check that a~skill path now reaches the skill resolver while workspace-relative paths are unaffected.Fixes #396
