Load nested workspace instructions lazily - #91
Ahmed-Hindy wants to merge 2 commits into
Conversation
📝 WalkthroughWalkthroughThe change replaces eager workspace-wide instruction discovery with lazy ancestor lookup. Path-aware tools return newly encountered instruction files once. Workspace state tracks loaded paths and filters instructions outside the workspace root. ChangesLazy instruction context
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR removes the expensive recursive workspace scan, but the current implementation can omit applicable workspace instructions after failed operations, from structured patch responses, or during cross-directory moves. These bounded correctness gaps can leave tools operating without required repository guidance, so the PR is not merge-ready until the affected paths are corrected.

Do not cache instructions before a failed read.
These lines mark newly found instruction files as loaded before readFileTool can return isError. If the first read in a nested directory fails, the handler returns no instruction content. A later successful read suppresses those instructions as already loaded.
Load and record the files only after a successful read, or restore the loader state on the error path. Add a regression test for a failed read followed by a successful read in the same directory.

Return instructions when the operation fails.
The write, edit, and shell handlers load and cache instructions before the operation. Their response.isError branches return the original response at Lines 85, 159, and 250. A first failed call can consume newly discovered files without delivering them. A retry can then omit the same files. Append instructionContent(agentsFiles, workspace.root) to error responses as well.

Load instruction files for both sides of a move.
src/apply-patch.ts includes previousPath for move results, but this loop resolves only file.path. A move across directories can therefore skip source-directory AGENTS.md or CLAUDE.md files. Resolve and load both file.previousPath and file.path for moves.

Include instructions in apply_patch structured output.
These lines add instruction blocks to content, but Line 139 still sets structuredContent.result to result. Structured-output consumers receive no newly discovered instructions. Set the structured result to contentText(content), as processToolResponse does.

@Ahmed-Hindy lazily loading nested AGENTS.md files is cool. I thought about the same approach too, but no coding harness currently does that. They usually let the model know which AGENTS.md files are available and instruct it to read them before it starts working inside those folder paths, so I went with the current approach. About the issue where a project has a lot of nested AGENTS.md files and discovery can fail because of the MCP timeout: one workaround could be to cap discovery at some threshold and stop searching once we hit it. you have any other approach for this? |
|
not really. this is what I had in mind and I have been test driving it for a couple of weeks |
|
ohh, how's the performance of agent loop throughout chatgpt's compaction? |
|
idk. I didn't measure performance that much. Devspace was timing out alot on large repos and was pretty much unusable. I still have alot of issues with it but this specific one is no longer part of it |

Summary
AGENTS.mdandCLAUDE.mdfiles only when a later path-aware tool enters their directory.open_workspace, which could block MCP requests long enough to time out.Root cause
open_workspacerecursively walked every descendant of the selected workspace to buildavailableAgentsFiles. Opening a parent folder that contains many repositories made this synchronous scan dominate the request and caused remote MCP clients to lose the connection.Closes #90
