- Removed ancestor directory walking logic from codex and opencode skill loading. Simplified project skills discovery to use single project directory instead of scanning up the filesystem tree. Fixed variable shadowing issues in gemini and github context file loading.
NanoGPT exposes per-thinking-level model IDs (e.g.
anthropic/claude-opus-4.6:thinking:low) as separate entries. These
pollute the model list and collide with parseModelString's thinking
level suffix stripping.
Filter out all :thinking and :thinking:level suffixed nanogpt models
during discovery. When a :thinking variant existed, mark the
corresponding base model as reasoning-capable. NanoGPT already supports
reasoning_effort via the OpenAI-compat path so no provider-side model
ID suffixing is needed.
- Added buildCompactHashlineDiffPreview() function to generate collapsed diff previews for tool responses.
- Enhanced EditTool response to include diff summary with added/removed line counts and compact preview.
- Added project-level discovery for .agent/ and .agents/ directories walking up to repository root.
- Implemented helper functions for truncating long diff runs (collapseFromStart, collapseFromEnd, collapseFromMiddle).
- Clarified pos semantics for replace, prepend, and append operations with concise bullet format.
- Simplified lines parameter documentation to focus on practical usage patterns.
- Rewrote rules section to emphasize structural anchoring and when to use prepend/append versus range replace.
* feat: monorepo-friendly discovery for AGENTS.md and skills
Support hierarchical config discovery in monorepos by walking up from
cwd through ancestor directories, combining files from all levels
instead of only checking the immediate working directory.
AGENTS.md context files:
- Change dedup key from file.level to file.level + depth, so context
files at different directory levels coexist instead of shadowing
- Root AGENTS.md and sub-project AGENTS.md are both included in the
system prompt, ordered from least specific to most specific
Skills:
- Modify all 4 providers with project-level skill directories (native,
claude, codex, opencode) to walk up from cwd through ancestors,
scanning for skills at each level
- Skills at closer directories win on name conflicts via existing
name-based dedup
Repo root boundary:
- Add findRepoRoot() utility that detects .git to identify repo root
- Add repoRoot field to LoadContext, computed once in loadCapability()
- All walk-up traversals (AGENTS.md, skills, nearest config dir) stop
at the repo root, preventing discovery from leaking outside the repo
- When not in a git repo, falls back to walking to filesystem root
Files changed:
- capability/fs.ts: add findRepoRoot()
- capability/types.ts: add repoRoot to LoadContext
- capability/index.ts: compute repoRoot in loadCapability()
- capability/context-file.ts: depth-aware dedup key
- discovery/agents-md.ts: bound walk-up at repo root
- discovery/builtin.ts: getAncestorDirs stopAt param, skill walk-up
- discovery/claude.ts: skill walk-up with repo root bound
- discovery/codex.ts: skill walk-up with repo root bound
- discovery/opencode.ts: skill walk-up with repo root bound
- extensibility/skills.ts: add repoRoot to inline LoadContext
* feat(agents-provider): add project-level discovery with ancestor walk-up for all capability types
The agents provider (.agent/.agents directories) previously only loaded
capabilities from the user home directory (~/.agent/, ~/.agents/). This
meant project-level .agents/ directories in monorepo roots were not
discovered when sessions started from subdirectories.
Add getProjectPathCandidates() helper that walks from cwd up to repoRoot,
scanning both .agent/ and .agents/ at each ancestor level. Apply this to
all six capability types: skills, rules, prompts, commands, context files
(AGENTS.md), and system prompts (SYSTEM.md). This matches the ancestor
walk-up behavior already present in the builtin (.omp), claude, codex,
and opencode providers.
All loaders now parallelize project-level and user-level scans via
Promise.all. Project-level results appear closest-first so dedup at the
capability layer picks the nearest override.
* fix(discovery): remove hard cap of 20 on ancestor directory walking
All walk-up loops already terminate naturally at repoRoot or filesystem
root. The depth < 20 / .slice(0, 20) / MAX_DEPTH caps were redundant
safety guards that would silently stop discovery in deeply nested
projects.
Removed from: agents.ts, agents-md.ts, builtin.ts, claude.ts, codex.ts,
opencode.ts, and corresponding test files.
* fix(agents-provider): set depth on project-level ContextFile entries for correct dedup
loadContextFiles was creating project-level ContextFile entries without
a depth field. Since contextFileCapability.key uses
`project:${file.depth ?? 0}`, all ancestor-level AGENTS.md files
collapsed to the same key and only the first survived dedup.
Compute depth via calculateDepth(cwd, ancestorDir) where ancestorDir is
two levels up from the file path (past the .agent/.agents config dir).
This gives each ancestor level a distinct dedup key.
* fix(discovery): stop ancestor walk-up at $HOME when not in a git repo
When repoRoot is null (no .git found), walk-up loops traversed all the
way to filesystem root. This caused $HOME to be scanned as a project-
level directory and then again as user-level, producing duplicates.
All providers now use `ctx.repoRoot ?? ctx.home` as the stop boundary:
stop at repoRoot if in a repo, otherwise stop at home. Applied to
agents.ts, agents-md.ts, builtin.ts, claude.ts, codex.ts, and
opencode.ts.
* fix(context-files): clamp depth >= 0 in dedup key and fix provider depth computations
The dedup key `project:${file.depth}` used raw depth, which could be
negative when providers computed it from config subdirectories (e.g.
.claude/, .github/, .gemini/) rather than the ancestor directory. This
caused same-scope cwd-level files to get distinct keys like project:-1
and project:0, bypassing dedup and injecting conflicting instructions.
Two-layer fix:
1. Key function: clamp to Math.max(0, depth) so any file at or below
cwd is treated as cwd-scope (depth 0). Defensive against future
providers.
2. Providers: fix root cause in claude.ts, gemini.ts, github.ts to
compute depth from the ancestor directory (parent of the config
subdir), not the config subdir itself.

parseModelString now extracts valid thinking level suffixes (e.g.,
"anthropic/claude-opus-4-6:high") instead of treating them as part of
the model ID. This enables per-role thinking levels in config:
modelRoles:
slow: anthropic/claude-opus-4-6:high
default: anthropic/claude-opus-4-6:low
smol: google/gemini-3-flash:medium
The thinking level is applied at startup, in SDK fallback resolution,
and during Ctrl+P role cycling. The original config string is preserved
on role cycle so the suffix round-trips correctly.

- Add dereferenceJsonSchema() that inlines local $ref pointers and strips
$defs/definitions from MCP tool schemas before they reach LLM providers.
Previously, Anthropic's convertTools() extracted only properties/required,
dropping $defs and leaving dangling $ref — the LLM never saw the actual
type definitions (e.g. SourceAnchorInput enum values from nucleus).
- Silence Ajv logger (logger: false) on all three instances that use
strict: false. MCP servers may declare non-standard format keywords
(e.g. "uint") that caused console.warn() to corrupt TUI output.
- Cache compiled Ajv validators per schema object identity in validation.ts,
eliminating redundant recompilation on every tool call.

* feat(mcp): resource notifications, subscriptions, and read_resource builtin tool
- Add MCP resource subscription lifecycle (subscribe/unsubscribe on connect/disconnect)
- Wire mcp.notifications setting with live toggle support
- Add debounced followUp injection for resource change notifications
- Add global read_resource builtin tool with server resolution by URI/template scheme
- Add MCP prompt commands (buildMCPPromptCommands) with array content support
- Add server instructions injection into system prompt with attribution
- Add mcp.notificationDebounceMs configurable setting
Client (client.ts):
listResources, listResourceTemplates, readResource with pagination
subscribeToResources, unsubscribeFromResources
listPrompts, getPrompt, serverSupportsPrompts
serverSupportsResources, serverSupportsResourceSubscriptions
Manager (manager.ts):
Notification dispatch with subscribed-URI guard
Concurrent refresh deduplication via pending promise map
setNotificationsEnabled with subscribe/unsubscribe toggle
Tests:
client-resources.test.ts (31 tests)
client-prompts.test.ts (20 tests)
mcp-read-resource.test.ts (13 tests)
* fix(mcp): address PR review - eager prompt init and stale subscription cleanup
P1: Make setOnPromptsChanged eagerly fire for servers that already
have prompts loaded. The callback is registered after MCP discovery
has already loaded prompts and fired the hook, so without this the
handler is never called on the common startup path. The fix is in
the manager itself (not the caller), eliminating the race condition
regardless of when the callback is wired.
P2: Unsubscribe removed resource URIs on resource refresh.
refreshServerResources was subscribing to the new URI set and
overwriting #subscribedResources without unsubscribing URIs that
were previously subscribed but no longer present, leaving stale
subscriptions active on the server.
* fix(mcp): add resources and prompts to /mcp help text and subcommand completions
* feat(mcp): add /mcp notifications command
Shows per-server notification capabilities with subscription state:
- Lists supported notification types (tools/list_changed, resources/list_changed,
prompts/list_changed) with check marks
- Shows resources/subscribe status with active subscription count
- Lists subscribed URIs with green ticks when notifications are enabled
- Displays overall enabled/disabled state (mcp.notifications setting)
* fix(mcp): address PR review comments on race conditions and stale state
- Await subscribe/unsubscribe in refreshServerResources so the refresh
promise doesn't resolve before subscriptions are settled, preventing
a second refresh from racing and overwriting tracking state (P2 #3)
- Guard setNotificationsEnabled subscribe .then() against a disable
that happens while the subscribe request is in-flight (P2 #5)
- Re-check mcp.notifications setting inside debounce setTimeout
callback so toggling off mid-window actually suppresses the
follow-up message (P2 #4)
- Fire onToolsChanged and onPromptsChanged callbacks in
disconnectServer so stale slash commands and tool registrations
are cleaned up when a server is removed (P2 #2)
