Migrate 203 test files (356 call sites) from fs.rm/fs.rmSync to
removeWithRetries/removeSyncWithRetries to reduce EBUSY test failures
on Windows. removeWithRetries is now exported from @oh-my-pi/pi-utils.
The migration uses a regex-based approach that:
- Replaces fs.rm(path, { recursive, force }) → removeWithRetries(path)
- Replaces fs.rmSync(path, { recursive, force }) → removeSyncWithRetries(path)
- Replaces fs.rm(path) → removeWithRetries(path) (no options)
- Skips fs.rm/fs.rmSync inside template literals (bun --eval scripts)
- Adds imports to existing @oh-my-pi/pi-utils import or creates new one
- Removes unused fs imports where fs.rm was the only fs usage (4 files)
- Standardized elision markers across all tool outputs and filters to use cohesive `[...N [type] elided...]`, `[...Nln elided...]`, and `[...xB elided...]` syntax.
- Updated documentation, prompts, and test expectations to reflect the unified elision format.
- Improved transcript viewer robustness by preventing content aliasing through path-inclusive signature hashing.
- Added logic to clear stale transcript content when associated session files are deleted, accompanied by verifying test cases.
The workspace tree shown in the system prompt renders per-entry modification
times as render-time relative ages ("9m ago") computed from Date.now() on
every build. Those strings drift between sessions ("9m ago" -> "10m ago",
"59m ago" -> "1h ago") while the files themselves are unchanged. Because the
tree sits ahead of the (multi-thousand-token) tool block and KV cache is
contextual, that one early change invalidates the cached prefix for everything
after it, forcing a full prompt re-prefill on the first request of every new
session — even when nothing in the workspace actually changed.
Fix: render a deterministic absolute UTC timestamp (YYYY-MM-DD HH:MM) derived
purely from the file's mtime for the cached system-prompt tree, so the rendered
block is byte-identical across sessions and only changes when a file actually
changes. Scoped via a new internal AssembleOptions.ageMode:
- buildWorkspaceTree (cached system prompt) -> "absolute"
- buildDirectoryTree (read-tool output, not cached) -> "relative" (unchanged)
renderNode now takes a per-pass age formatter instead of reading Date.now()
directly.
Measured on a local llama.cpp server (single user, prompt cache on): with a
file whose age ticks between two back-to-back sessions, the unpatched build
re-prefills the full prefix on session 2 (27,124 prompt tokens, 46s); with this
change session 2 is a cache hit (13 tokens, 2s). Existing tests are unaffected
(they assert on filenames/order/elision, not on age strings); two regression
tests added.
- Added `listWorkspace` native binding and API types, exporting bounded workspace trees with AGENTS.md candidates.
- Reworked `buildWorkspaceTree` and `buildDirectoryTree` to call `listWorkspace` with 5s timeout defaults.
- Replaced startup AGENTS.md discovery with workspace-tree-only scanning and removed legacy AgentsMdSearch session plumbing.
- Updated `WorkspaceTree` and system prompt context to expose `agentsMdFiles` and aligned tests/changelog expectations.
- BuildWorkspaceTree now attempts to list files via `git ls-files` and builds a child index for tree rendering, avoiding native recursion when git output is available.
- `buildDirectoryTree` gained an optional `childIndex` path map, `tryListGitFiles` now applies a 3s timeout and falls back to existing native scan on failure or timeout.
- Added a workspace-tree test that verifies git-backed listing skips gitignored entries while including tracked workspace files.
- Added DirectoryTree, DirectoryTreeOptions, and buildDirectoryTree exports for configurable tree rendering.
- Changed read tool directory output to use buildDirectoryTree with depth and exclusion limits.
- Added read.summarize settings and summary-mode parseable read output behavior when no selector is used.
- Added tests for truncated root/child listings and hidden or excluded entry filtering.
- Added `WorkspaceTree` and `buildWorkspaceTree` APIs for working-directory tree rendering with limits.
- Extended `buildSystemPrompt` and `createAgentSession` to resolve and pass workspace tree context for system prompts.
- Updated the system prompt template to include a `<workspace-tree>` section with truncation notices before append output.
- Added workspace-tree and system-prompt tests covering sorting, truncation, exclusions, and prompt ordering.
