Keep AGENTS.md instructions in a structured stable prompt, remove optional Skills and MCP activation, and expose the intended core tool roster with explicit pending interaction and capability-search tools. Signed-off-by: Hari Srinivasan <harisrini21@gmail.com>
Add strict questionnaire contracts and daemon-owned interaction handling across the runtime and SDK. Render the same canonical requests as stepped flows in the TUI and web clients, with durable session eligibility and restart-safe cancellation. Signed-off-by: Hari Srinivasan <harisrini21@gmail.com>
Compact before model requests using configurable token budgets and retry one classified provider overflow before output is exposed. Preserve split-turn context, cumulative file tracking, and cache-safe summaries. Record queued and active compaction lifecycle state canonically, reconcile interrupted work after restart, and let TUI and web clients queue manual compaction behind an active response. Signed-off-by: Hari Srinivasan <harisrini21@gmail.com>
Discover AGENTS.md files from the repository root to the session directory, apply same-directory overrides, and reject invalid or escaping resources. Record exact resource snapshots canonically, project them through the SDK, preserve them across restart, and rediscover them on explicit reload. Signed-off-by: Hari Srinivasan <harisrini21@gmail.com>

Merge Risk: 🟡 Moderate · up to Several functional gaps remain in the new extension and compaction features. An extension that subscribes to the documented extension_event fails to load and blocks session start. Provider response hooks that fail can leave connections open. Cancelling extension and session mutations does not stop them. A stale extension path can break extension listing. CI formatting and a runtime integration test also fail. Resolve these before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Inline comments:
In `@docs/architecture/web-protocol.md`:
- Line 18: Update the recovery guidance in SETUP.md to replace the stale session
wire version 13 reference with version 25, while preserving the separate
host-control version 1 wording and the rest of the mismatch guidance.
In `@docs/extensions.md`:
- Around line 82-83: Update the `on("tool.call", handler)` documentation to
state that the handler receives all canonical tool calls, including built-in
tools such as `bash`; keep the blocking and input-copy behavior accurate, and
align the example and capability description with this broader scope.
In `@packages/ai/src/model-error.ts`:
- Line 18: Update the context-limit markers in the model-error classification to
remove the broad “maximum number of tokens” match or restrict it to
input/context-specific errors. Ensure invalid output-token-limit errors do not
enter context-overflow retry or compaction handling.
In `@packages/daemon/src/daemon.ts`:
- Around line 1053-1054: Update the cancellable-method expression in dispatch to
include "mcp.config.probe", ensuring the existing
mcpConfigurationService().probe call receives an AbortSignal and request
cancellation works.
In `@packages/daemon/src/session-manager.ts`:
- Around line 1214-1218: Update the rename command flow after interceptCommand
and its string-type check to catch ProtocolValidationError from
managed.session.rename, convert it to a command_blocked DaemonError including
the validation message and original error as cause, and rethrow all other errors
unchanged.
In `@packages/extensions/host/src/index.ts`:
- Line 44: Create the Ajv validator inside loadDaemonExtensions so each load
receives a fresh schema cache, remove the module-level JSON_SCHEMA_VALIDATOR,
and pass the per-load validator into kernelTool for both schema compilation and
errorsText generation. Update all kernelTool call sites accordingly.
In `@packages/extensions/mcp/src/capabilities.ts`:
- Around line 329-352: Update the cache-hit branch in the metadata selection
flow to reuse the cached entry while replacing its stale definitionFingerprint
with the current value. Keep the discovered metadata unchanged and preserve the
existing cache-miss discovery and failure handling.
In `@packages/extensions/mcp/src/manager.ts`:
- Around line 585-593: Update the OAuth retry branch in the finish flow to clean
up when any retry step fails: wrap the transport-type check, finishAuth,
transport retry, and client.connect calls in a try/catch, then await
candidate.oauth.close() and candidate.cleanup?.() before rethrowing the original
error. Preserve the successful return path with the retried transport and OAuth
session.
In `@packages/extensions/skills/src/index.ts`:
- Around line 191-195: Update readFrontmatter to decode the fixed-size probe
with TextDecoder using streaming mode, so a trailing incomplete UTF-8 sequence
is tolerated while invalid sequences still raise SkillValidationError. Preserve
binary-data validation and the existing strict full-file decoding behavior in
loadSkill.
In `@packages/protocol/src/wire.ts`:
- Around line 1609-1616: Update the configuration non-empty validation to
include configured.userQuestions as an accepted standalone field, and add
userQuestions to the corresponding ProtocolValidationError message while
preserving the existing checks for all other configuration fields.
In `@packages/runtime/src/local-runtime.ts`:
- Around line 492-556: Wrap the capability and MCP setup after
loadDaemonExtensions in a try/catch, including host composition and
capability-tool registration. In the catch, await
daemonExtensions.host.dispose() before rethrowing the original error, ensuring
failures do not leak extension resources.
In `@packages/sdk/src/projector.ts`:
- Around line 606-609: Update the compaction.failed branch in the projector
event handler so retryable failures and non-manual compaction reasons keep the
operation running without calling clearActivity; only manual, non-retryable
failures should update the operation to failed and clear activity. Use
event.payload.willRetry and event.payload.reason, matching the behavior of the
adjacent context.compacted branch.
In `@packages/web/src/app.tsx`:
- Line 1933: Update the MCP add and import operation handlers around setMcpError
to set mcpBusy before probing, and reset it in a finally block so Reload,
Remove, and Enable controls remain disabled throughout probing and saving.
- Line 1959: Update the server import persistence flow around
client.upsertMcpServer so saving the imported servers is atomic: use the
daemon’s batch transaction mechanism to apply all upserts together, or restore
the prior configuration if any upsert fails. Preserve the all-or-nothing
behavior and avoid leaving partially persisted servers.

In `@docs/architecture/web-protocol.md`:
- Line 22: The documented allowed-error matrix must include the extension and
session method entries represented by RPC_METHOD_ERROR_CODES. Add extension.*
method rows allowing extension_failed, and add the missing session-method rows
allowing extension_failed and command_blocked, matching the exported error map
exactly.
In `@docs/extensions.md`:
- Line 85: Update the project-local extension loading statement in the locations
section to clarify that only untrusted project-local extension directories are
excluded, while trusted directories remain loadable through extension.trust.
In `@packages/daemon/src/daemon.ts`:
- Around line 816-830: Update the CommandJournal effect callback in the request
handling flow to pass the existing abort signal into dispatch, ensuring
retryable mutations such as extension installation and session reload receive
cancellation. Preserve the current normalized request, send, state, and
acceptance arguments while adding signal to the dispatch call.
- Around line 1068-1069: Update the extension-management request handler to
obtain the session cwd directly from persisted session state via
session.created.payload.cwd, rather than calling SessionManager.cwd(), so
unopened sessions are not resumed or loaded with extensions before list/disable

preserving the validated commit hash. In the Git reinstall package-name
resolution, reuse the stored configuration entry whose spec matches spec when
expectedName and the changed-dependency lookup both produce no name; load

- Around line 481-483: Update the abort test around the generated extension
factory so it exposes a readiness callback or promise and resolves it once the
factory observes axl.signal before waiting for cancellation. Await that
readiness signal instead of using the fixed five-millisecond delay, then call
controller.abort() and retain the existing rejection assertion.

Discover trusted global `~/.axl/mcp.json` using the common `mcpServers` shape. Project-local MCP configuration is no longer loaded. Add daemon-owned MCP configuration RPCs, a progressively disclosed `configure_mcp` model tool, `/mcp` in the TUI, and an MCP settings tab in the web client. Managed writes are validated, atomic, mode 0600, and followed by an active-session reload. Add a private, atomic, versioned metadata cache and BM25 capability records for enabled MCP tools. Expose inactive provider-native schemas with session-scoped activation, deterministic collision-resistant names, and frozen direct dispatch without a generic `mcp` gateway. Preserve sandboxed stdio, lazy transport ownership, cancellation, approvals, progress, required tasks, redaction, blobs, sampling, elicitation, and OAuth. Advance the wire protocol to version 22.

An interrupted or failed turn that produced no content and no tool calls was appended to the live session's model history, while replay from the event log already filtered that shape. Providers reject an empty assistant message, so every later prompt in the session failed with provider_stream_failure until the daemon restarted. Apply the replay rule to the live path so both histories stay identical. The canonical assistant.message event is still recorded. Signed-off-by: Shaan Narendran <shaannaren06@gmail.com>
Replace the preset list with a real configuration flow. Users paste a
server's README block, URL, or command line (or answer a guided
questionnaire), review the exact JSON to be written, and Axl connects
first and saves only if the server answers.
Daemon and protocol:
- `mcp.config.list` projects per-server discovery status (`discovered`,
`failed` with a redacted error, `disabled`, `pending`) and tool summaries
from the metadata cache.
- New `mcp.config.probe` connects to a candidate definition without
persisting it; `authorization: "required"` reports servers that need a
browser login. Wire protocol 22 -> 23, event format unchanged.
- A server that fails discovery no longer fails the session. It contributes
no capabilities, its failure is cached, and the rest load.
- Header and env values accept `${VAR}` templates such as
`Bearer ${TOKEN}`; only UPPER_CASE names are variable references and
literal values are rejected so secrets never enter `mcp.json`.
- A credential-less HTTP server that answers 401 arms OAuth automatically;
the user still approves in the browser.
SDK: shared add-flow questions, draft-to-definition mapping, README import
parser (mcpServers/servers blocks, `type`, `disabled`, `${input:id}` ->
`${ID}`, bare URLs and command lines), required-environment hints, and
`probeMcpServer()`. Presets removed.
TUI: `/mcp` opens a panel with status, tool counts, activated-tool markers,
and keys for paste, add, enable/disable, remove, reload. Add and paste reuse
the questionnaire overlay with a review step and inline probe errors.
Startup and reload notices plus an `mcp:discovered/total` footer segment.
In fullscreen mode every dialog now floats as a centered box over a dimmed
transcript with the editor still visible. Dialog rows can no longer break
the frame with embedded newlines, and the caret tracks the prompt.
Web: MCP tab with the same data and actions, `QuestionnaireForm` extracted
from the interaction card and shared with Paste config and Add server.

The daemon records interaction.resolved under the responding RPC's operation id so retries stay idempotent. The projector marked that foreign id as running and never saw it complete, so after any MCP approval the turn's real operation finished but activeOperationId stayed set and clients showed Working forever with Esc having nothing to interrupt. Resume the operation that requested the interaction instead. Signed-off-by: Shaan Narendran <shaannaren06@gmail.com>
Add an in-process daemon extension surface modelled on file-based
extension loading. A `.ts` or `.js` module in `~/.axl/extensions/`
exports a factory that receives `DaemonExtensionApi`:
- `registerTool` adds a tool indexed behind `capability_search`;
- `on("tool.call")` blocks a tool call before it runs, failing closed;
- `on("command")` replaces the inputs of, or refuses, a built-in command;
- `on("session.event")` observes every durable canonical event; and
- `track` registers cleanup for session end.
The kernel `ExtensionHost` gains `beforeToolCall`, `beforeCommand`, and
`observe`, plus `composeExtensionHosts` and `interceptCommand`. The
agent session consults the host before executing a tool and before
every compaction, including threshold and overflow compaction, so an
extension can supply its own summary or refuse. `@axl/extension-host`
discovers, imports, validates, and hosts the modules; an invalid
extension fails session start with its path and reason.
Extensions run inside the daemon process and are trusted by placement.
Node 22 strips TypeScript types natively, so no loader dependency is
added.

Route every session-bound built-in command through the extension host before it runs: compact (client, model, and automatic), reload, model, thinking, request, configure, fork, clone, and rename. An extension may return replacement arguments or a refusal; a thrown handler also refuses. The daemon revalidates replaced configuration and fork inputs through the protocol parsers and rejects invalid replacements. Add the `command_blocked` RPC error so the refusal reason reaches the client instead of collapsing to `internal_error`, allow it on the six affected methods, export `parseSessionConfiguration`, and advance the wire protocol from 23 to 24. The persisted event format stays 1. Model-triggered compaction now records `source: "model"` so extensions can tell who asked. Signed-off-by: Shaan Narendran <shaannaren06@gmail.com>
Rewrite roadmap section 5 and section 10.4: daemon extensions are user files in `~/.axl/extensions/` that run inside the daemon process with its permissions. Placing a file there is the trust decision. Drop the Phase 6 and Phase 7 items that required an out-of-process host for executable extensions and replace them with project-trust and daemon-level command follow-ups. Local MCP servers stay sandboxed. Document the extension surface in the README and ignore `.reference/` so read-only reference checkouts can live inside the repository directory without reaching lint, format, or generated-file checks.

CodeQL flagged two regular expressions in the README-paste importer that backtrack polynomially on untrusted input: the name edge trimmer's `[^a-z0-9_.-]+$` alternation and the `//` comment stripper's `[^\n"]*$`. Replace both with index scans that keep the same behaviour: a name loses characters that may not start or end it, and a comment starts at the first `//` after the last double quote on its line so URLs inside strings survive. Add a regression test with 50,000 repeated commas and slashes. Signed-off-by: Shaan Narendran <shaannaren06@gmail.com>

Add browser dialogs, theme access, shortcuts, DOM widgets, tool, message, and entry renderers, and event observation to the public web extension API. The first-party /browser-extensions command manages extensions through the same public host as installed modules. Dialogs close, clean up once, and restore focus. Shortcuts match canonical names by physical key code. Widget cleanup runs once on unmount or host disposal. Duplicate extension identities are rejected before import, and event dispatch isolates handler failures. Tool renderers use the model-visible tool name, matching the TUI. Browser extension commands report their own result instead of a generic completion notice. WebElement resolves to HTMLElement only in DOM programs, so Node packages stay free of DOM globals. Add a paired daemon and browser example with install steps, and record installed-artifact browser evidence in the parity matrix. Signed-off-by: Hari Srinivasan <harisrini21@gmail.com>
Acknowledge only the newest queued cursor of an event burst. The daemon treats acknowledgements as cumulative, and one acknowledgement per replayed event exceeded the web gateway burst limit after /reload or extension enablement changes, which closed the browser connection.

Allow session.create and session.resume to report catalog_refresh_failed instead of a generic internal error.
