Summary

  • Serve cyrus-tools via the shared Fastify MCP endpoint and enforce API-key auth on /mcp/cyrus-tools.
  • Ensure Codex runner forwards HTTP MCP auth headers correctly so authenticated MCP servers (including cyrus-tools and other header-auth servers) initialize successfully.
  • Keep MCP configuration behavior consistent across runners while preserving Codex-native auth fields.

Implementation Approach

  • Added request-time auth validation in the edge worker MCP route for cyrus-tools, validating Authorization: Bearer <CYRUS_API_KEY> when configured.
  • Updated generated MCP server config for cyrus-tools to include the same bearer auth header.
  • Updated Codex MCP mapping to translate generic headers into Codex http_headers, while preserving explicit http_headers, env_http_headers, and bearer_token_env_var when already provided.
  • Added dedicated Codex runner tests to cover header translation and pass-through behavior.
  • Updated changelog entries for CYPACK-817 in both user-facing and internal changelogs.

Testing Performed

  • pnpm --filter cyrus-codex-runner test:run
  • pnpm --filter cyrus-codex-runner typecheck
  • pnpm exec biome check packages/codex-runner/src/CodexRunner.ts packages/codex-runner/test/CodexRunner.mcp-config.test.ts
  • pnpm lint
  • pnpm typecheck
  • pnpm test:packages:run

Breaking Changes / Migration Notes

  • cyrus-tools MCP now requires Authorization: Bearer <CYRUS_API_KEY> on /mcp/cyrus-tools when CYRUS_API_KEY is set.
  • MCP clients must send the configured bearer token header for successful MCP initialization.

P1 Badge Generate unguessable IDs for cyrus-tools MCP contexts

The new Fastify MCP route authorizes requests solely by the x-cyrus-mcp-context-id header, but this context ID is now deterministic (${repository.id}:${parentSessionId}), which turns it into a predictable bearer token. In deployments where Cyrus is bound externally (for example with CYRUS_HOST_EXTERNAL=true), anyone who can learn or infer a session ID can call /mcp/cyrus-tools and invoke Linear-mutating tools with the repository token. Use a cryptographically random per-session secret (and expire it) instead of deriving the context ID from stable identifiers.

P2 Badge Preserve explicit http_headers when generic headers exist

If a server config contains both Codex-native http_headers and generic headers, the second assignment overwrites http_headers with headers, so explicitly configured Codex auth headers are silently dropped. This breaks authenticated MCP setups that intentionally provide Codex-specific headers (for example via http_headers/env_http_headers) alongside generic metadata, and contradicts the intended pass-through behavior.

* feat: Read Slack bot token from SLACK_BOT_TOKEN env var with header fallback

Read the Slack bot token from the SLACK_BOT_TOKEN environment variable as
the primary source, falling back to the X-Slack-Bot-Token header for
backwards compatibility. Logs a warning when using the header fallback to
help identify when infrastructure hasn't been updated yet.

Remove the backwards-compatibility fallback that read the Slack bot
token from the X-Slack-Bot-Token request header when the SLACK_BOT_TOKEN
env var was not set. The previous implementation was in beta, so no
transition period is needed. The token should only exist as an
environment variable.

- Simplify getSlackBotToken() to only read process.env.SLACK_BOT_TOKEN
- Remove header fallback logic and warning log
- Remove 3 fallback-related tests, add env-var-missing test
- Update SlackChatAdapter warning to reference env var instead of header
- Update changelogs to reflect no-fallback behavior

* feat: Add cyrus-tools MCP to Slack agent sessions

Configure Slack sessions with the same cyrus-tools and Linear MCP
servers that Linear-triggered sessions use, via the first repository's
Linear token. This gives Slack agent sessions access to Linear MCP
tools for issue management.

* fix: Add MCP tool permissions to Slack agent sessions

Derive MCP tool permission names (mcp__linear, mcp__cyrus-tools) from
the configured MCP servers and include them in the allowedTools list.
Without this, the Claude session could see the MCP servers but was
denied permission to call their tools.

* Refactor logging to a dedicated logger (#818)

* Fix: Disable MCP tools when disallowAllTools is true

Summary subroutines (concise-summary, verbose-summary, question-answer,
plan-summary, etc.) have disallowAllTools: true, but MCP tools like
Linear's create_comment were still accessible because MCP config was
always provided regardless of this setting.

This change conditionally disables mcpConfig and mcpConfigPath when
disallowAllTools is true, ensuring the agent truly has no tool access
during summary subroutines.

Closes CYPACK-760

* Refactor logging to a dedicated logger

* Add source context to sessions when emitting logs

* Fix issue where single-turn sub-routines would silently fail by exceeding max-turns. Now, when the result message of a single-turn sub-routine is an error, the result text from the previous sub-routine is emitted to Linear as a result message.

* Respect agent guidance for draft PRs and use --track for worktrees (#834)

- Update gh-pr subroutine to conditionally gate `gh pr ready` based on
  agent guidance (respects --draft flag in workspace guidance)
- Update changelog-update subroutine to include --base flag in PR creation
  targeting the configured base branch from context
- Add --track flag to git worktree add commands to properly set upstream
  tracking branch

Fixes issues where PRs were auto-converted from draft to ready and
worktrees weren't tracking the correct upstream branch.

* Cherry-pick d5d9e5a0: Fix single-turn subroutine silent failures (#843)

* Cherry-pick d5d9e5a0: Fix single-turn subroutine silent failures

Cherry-picks commit d5d9e5a0 from refactor/improved-logging branch.
Resolves merge conflicts adapting logging refactor patterns
(sessionId/log.info) to current branch patterns
(linearAgentActivitySessionId/console.log).

When a single-turn subroutine exits with an error (e.g. error_max_turns),
AgentSessionManager now recovers by using the last completed subroutine's
result via ProcedureAnalyzer.getLastSubroutineResult(), allowing the
procedure to continue to completion instead of failing silently.

Also adds tools config pass-through to ClaudeRunner and EdgeWorker
so disallowAllTools subroutines properly disable built-in tools.

verify required keys without failing on additional process.env
entries.

* Fix TaskCreate/TaskGet formatting, add ToolSearch/TaskOutput formatting, include task subject in TaskUpdate/TaskGet (#846)

* Fix TaskCreate/TaskGet formatting for parallel execution, add ToolSearch and TaskOutput formatting

TaskCreate now renders as concise checklist items (⏳ **subject**) instead of
verbose multi-line format, better suited for parallel async execution. TaskGet
shows subject with ID when enriched. ToolSearch renders as a thought with
descriptive formatting. TaskOutput shows task status with blocking/non-blocking
context.

TaskUpdate and TaskGet now always display the task number (e.g. "Task #123")
instead of the subject description for consistency with parallel execution.
ToolSearch now shows the query directly as the parameter value, matching
the pattern of other tools like Bash (command) and Read (file_path).

* Enrich TaskUpdate/TaskGet activities with task subject from cache and result parsing

TaskUpdate and TaskGet tool inputs don't include the task subject, causing
Linear activities to show only "Task #3" without context. This change defers
their activity posting from tool_use time to tool_result time, where subject
can be sourced from: (1) a cache populated by TaskCreate results, or
(2) parsing the Subject field from TaskGet result content.

* feat: use forwarded GitHub installation token for PR comment replies

Updates GitHub webhook handling to extract and use the X-GitHub-Installation-Token
header forwarded from CYHOST instead of relying on process.env.GITHUB_TOKEN.

Changes:
- Extended GitHubWebhookEvent type with optional installationToken field
- GitHubEventTransport now extracts X-GitHub-Installation-Token header from incoming webhooks
- EdgeWorker.postGitHubReply() prefers forwarded token over process.env.GITHUB_TOKEN
- Added comprehensive tests for token extraction behavior (2 new tests)

This enables self-hosted Cyrus processes to post PR comment replies using
short-lived (1-hour) GitHub App installation tokens.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

* fix: use forwarded installation token in fetchPRBranchRef

Update EdgeWorker.fetchPRBranchRef() to prefer event.installationToken
over process.env.GITHUB_TOKEN for authenticating GitHub API calls to
fetch PR branch details. This fixes 404 errors in self-hosted setups
where process.env.GITHUB_TOKEN doesn't exist, allowing private repo
PR details to be fetched using forwarded GitHub App installation tokens.

- Changed line 866 in EdgeWorker.ts from process.env.GITHUB_TOKEN to
  event.installationToken || process.env.GITHUB_TOKEN
- Updated comment to reflect new token preference behavior
- Added comprehensive test coverage in EdgeWorker.fetchPRBranchRef.test.ts
- Updated CHANGELOG.internal.md to document the change

Fixes CYPACK-774

* fix: guard activity-posting methods for non-Linear sessions

- Add externalSessionId guard to postAnalyzingThought and
  postProcedureSelectionThought so they skip posting (and don't error)
  for GitHub/Slack sessions
- Remove activeWebhookCount tracking from handleMessage() to avoid
  double-counting with legacy webhook handlers
- Normalize all activity-posting guard clauses from warn to debug level,
  since non-Linear sessions hitting these paths is expected behavior
- Add tests verifying GitHub sessions skip all Linear activity posting

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: add unified internal message bus with platform translators

Introduce a platform-agnostic message layer that translates webhook
payloads from Linear and GitHub into a unified InternalMessage format.
This enables handleMessage() in EdgeWorker to process events from all
platforms through a single code path.

- Add InternalMessage type system in core (SessionStart, UserPrompt,
  StopSignal, ContentUpdate, Unassign) with type guards and platform refs
- Add IMessageTranslator interface for platform-specific translators
- Implement LinearMessageTranslator and GitHubMessageTranslator
- Wire translators into event transports to emit 'message' alongside
  legacy 'event' for backward compatibility
- Replace old linear-event-transport tests with translator-focused tests

* feat: reuse existing worktree when branch is already checked out

When a GitHub webhook arrives for a PR branch that's already checked out
in a Linear session's worktree, git worktree add fails. Instead of
falling back to an empty directory, detect and reuse the existing
worktree path — both proactively (before attempting creation) and as a
safety net (parsing the git error message in the catch block).

Also adds a concurrency warning log when a GitHub session shares a
workspace with an active Linear session.

interface. This enables future support for non-Linear activity sinks.

- Expand IActivitySink with ActivitySignal, ActivityPostOptions, ActivityPostResult types
- Update LinearActivitySink to map string signals to AgentActivitySignal enum
- Replace issueTracker constructor param with activitySink in AgentSessionManager
- Rename syncEntryToLinear → syncEntryToActivitySink
- Create LinearActivitySink at both EdgeWorker construction sites
- Update all test files to use IActivitySink mock pattern

* feat: Add Slack event transport for @mention webhooks (CYPACK-807)

Implement cyrus-slack-event-transport package to receive Slack app_mention
webhooks forwarded from CYHOST. Adds SlackEventTransport (Fastify endpoint
with Bearer token auth), SlackMessageTranslator (translates to unified
SessionStartMessage/UserPromptMessage), thread-aware session keys, and
Slack platform data types in cyrus-core.

* feat: Handle Slack @mention webhooks as agent sessions with thread reply (CYPACK-807)

Slack @mentions now trigger full agent sessions using the first configured
repository, with results posted back as threaded replies in Slack.

* fix: Use plain systemPrompt for Slack sessions to avoid empty text block error

The claude_code preset constructs context blocks (CLAUDE.md, git status)
that are empty in Slack's non-git empty workspace directories, causing
"cache_control cannot be set for empty text blocks" API errors. Using a
direct systemPrompt string bypasses the preset entirely.

* fix: Handle empty Slack @mention by providing default prompt

Reverts 166d88be which switched from appendSystemPrompt to plain
systemPrompt — we need the claude_code preset. The actual root cause
was an empty user prompt: when a Slack message is just "@cyrus" with
no other text, stripMention returns "", which the SDK sends as an
empty text block with cache_control, rejected by the API. Now falls
back to "Ask the user for more context" when the stripped text is empty.

* fix: Skip procedure routing for Slack sessions on completion

Slack sessions are created without a ProcedureAnalyzer since they are
simple conversational sessions, not multi-subroutine workflows. When
the session completed, completeSession called handleProcedureCompletion
which threw "ProcedureAnalyzer not available". Now gracefully returns
early when no ProcedureAnalyzer is configured.

* feat: Add Slack thread context to agent sessions

When a user @mentions Cyrus in a Slack thread, fetch the preceding
conversation via conversations.replies and prepend it as XML context
to the user prompt. This gives the agent visibility into what users
were discussing before invoking it.

* refactor: Extract Slack integration via ChatPlatformAdapter pattern

Introduce ChatPlatformAdapter<TEvent> interface and ChatSessionHandler<TEvent>
class to decouple chat platform session lifecycle from EdgeWorker. Slack becomes
the first adapter implementation (SlackChatAdapter), removing ~450 lines and 9
private methods from EdgeWorker.ts. Adding a new chat platform now requires only
an adapter (~80 lines) instead of duplicating session management logic.

* refactor: Add createChatSession for issue-free sessions, fix appendSystemPrompt

Addresses PR review feedback:
- Add AgentSessionManager.createChatSession() for chat platforms that
  don't have issue context, avoiding synthetic IssueMinimal objects
- ChatSessionHandler now uses createChatSession instead of
  createLinearAgentSession with fake issue data
- Fix ChatSessionHandler.buildRunnerConfig using appendSystemPrompt
  instead of systemPrompt (re-introduced the cache_control bug)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* revert: Use appendSystemPrompt for chat sessions (root cause was empty prompt)

The cache_control error was caused by an empty prompt string after
stripping the @mention (e.g. just "@cyrus" with no text), not by the
claude_code preset. Revert back to appendSystemPrompt so chat sessions
benefit from the full Claude Code system prompt.

* fix: Use streaming mode for chat sessions to enable follow-up message injection

Chat sessions (Slack threads) were started with runner.start() (string mode),
so follow-up messages arriving mid-session would crash with "Cannot add stream
message when not in streaming mode". Switch to startStreaming() and add an
isStreaming() guard before calling addStreamMessage().

* Cherry-pick d5d9e5a0: Fix single-turn subroutine silent failures

Cherry-picks commit d5d9e5a0 from refactor/improved-logging branch.
Resolves merge conflicts adapting logging refactor patterns
(sessionId/log.info) to current branch patterns
(linearAgentActivitySessionId/console.log).

When a single-turn subroutine exits with an error (e.g. error_max_turns),
AgentSessionManager now recovers by using the last completed subroutine's
result via ProcedureAnalyzer.getLastSubroutineResult(), allowing the
procedure to continue to completion instead of failing silently.

Also adds tools config pass-through to ClaudeRunner and EdgeWorker
so disallowAllTools subroutines properly disable built-in tools.

TaskCreate now renders as concise checklist items (⏳ **subject**) instead of

descriptive formatting. TaskOutput shows task status with blocking/non-blocking

* Enrich TaskUpdate/TaskGet activities with task subject from cache and result parsing

TaskUpdate and TaskGet tool inputs don't include the task subject, causing
Linear activities to show only "Task #3" without context. This change defers

can be sourced from: (1) a cache populated by TaskCreate results, or
(2) parsing the Subject field from TaskGet result content.

* Fix spawn node ENOENT by passing process.env to Claude SDK

The env option only contained 3 hardcoded vars, causing PATH to be
missing from the spawned Claude Code process.

* Cherry-pick d5d9e5a0: Fix single-turn subroutine silent failures (#843)

* Cherry-pick d5d9e5a0: Fix single-turn subroutine silent failures

Cherry-picks commit d5d9e5a0 from refactor/improved-logging branch.
Resolves merge conflicts adapting logging refactor patterns
(sessionId/log.info) to current branch patterns
(linearAgentActivitySessionId/console.log).

When a single-turn subroutine exits with an error (e.g. error_max_turns),
AgentSessionManager now recovers by using the last completed subroutine's
result via ProcedureAnalyzer.getLastSubroutineResult(), allowing the
procedure to continue to completion instead of failing silently.

Also adds tools config pass-through to ClaudeRunner and EdgeWorker
so disallowAllTools subroutines properly disable built-in tools.

* Update changelogs for CYPACK-792 (#843)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Fix ClaudeRunner test env assertions after process.env spread

Tests expected env to contain only 3 explicit keys, but commit
6e8d873d added ...process.env to prevent spawn ENOENT errors.
Updated assertions to use expect.objectContaining() so tests
verify required keys without failing on additional process.env
entries.

* Fix TaskCreate/TaskGet formatting, add ToolSearch/TaskOutput formatting, include task subject in TaskUpdate/TaskGet (#846)

* Fix TaskCreate/TaskGet formatting for parallel execution, add ToolSearch and TaskOutput formatting

TaskCreate now renders as concise checklist items (⏳ **subject**) instead of
verbose multi-line format, better suited for parallel async execution. TaskGet
shows subject with ID when enriched. ToolSearch renders as a thought with
descriptive formatting. TaskOutput shows task status with blocking/non-blocking
context.

* Add changelog entries for CYPACK-795

* Simplify TaskUpdate/TaskGet to use task number, show ToolSearch query directly

TaskUpdate and TaskGet now always display the task number (e.g. "Task #123")
instead of the subject description for consistency with parallel execution.
ToolSearch now shows the query directly as the parameter value, matching
the pattern of other tools like Bash (command) and Read (file_path).

* Revert Gemini runner formatting changes (not applicable to these tools)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Include task subject in TaskUpdate and TaskGet formatting

TaskUpdate and TaskGet now display the task's short description
alongside the task number (e.g., "✅ Task #3 — Fix login bug")
when a subject is available, falling back to number-only when not.

* Enrich TaskUpdate/TaskGet activities with task subject (CYPACK-797) (#847)

* Enrich TaskUpdate/TaskGet activities with task subject from cache and result parsing

TaskUpdate and TaskGet tool inputs don't include the task subject, causing
Linear activities to show only "Task #3" without context. This change defers
their activity posting from tool_use time to tool_result time, where subject
can be sourced from: (1) a cache populated by TaskCreate results, or
(2) parsing the Subject field from TaskGet result content.

* fix(orchestrator): ensure issues are created with 'To Do' status instead of 'Triage' (#815)

* fix(orchestrator): ensure issues are created with 'To Do' status instead of 'Triage'

Update orchestrator system prompts to explicitly require setting state to
"To Do" when creating issues with mcp__linear__create_issue. Previously,
issues were being created with default "Triage" status.

Changes to both orchestrator.md (v2.5.0) and graphite-orchestrator.md (v1.3.0):
- Added state requirement to Required Tools section
- Added Status bullet point in Decompose section
- Added status checklist item in Sub-Issue Creation Checklist

* feat(runners): add codex/cursor harness support and F1 validation

* fix(cursor-runner): support non-mock cursor F1 session output

* Fix cursor harness verification regressions

* fix(ci): resolve build type errors in config-updater and core session types

* fix(edge-worker): wire cursor runner selection and prompt assets

* docs(changelog): frame cursor harness as major feature

* docs(changelog): use user-facing framing for cursor entry

* docs(changelog): clarify cursor selector usage

* fix(build): remove baseUrl/paths from tsconfig to fix dist output structure

The baseUrl pointing to monorepo root caused TypeScript to expand rootDir,
nesting compiled output under dist/edge-worker/src/ instead of dist/.
This broke module resolution since package.json declares main as dist/index.js.
Also adds missing cyrus-cursor-runner dependency to edge-worker.

* refactor: Extract 5 service modules from EdgeWorker.ts (CYPACK-822)

Extract logically grouped functionality into dedicated modules to improve
readability and maintainability of the 7,687-line EdgeWorker.ts file:

- ActivityPoster: Linear activity posting (289 lines)
- AttachmentService: Attachment download and manifest generation (488 lines)
- ConfigManager: Config file watching, reload, and change detection (320 lines)
- PromptBuilder: Prompt assembly, system prompts, and issue context (1,270 lines)
- RunnerSelectionService: Runner/model selection and tool configuration (498 lines)

EdgeWorker.ts reduced from 7,687 to 5,466 lines (29% reduction). All 522
tests passing, typecheck clean, lint clean.

* feat: Read Slack bot token from SLACK_BOT_TOKEN env var with header fallback

Read the Slack bot token from the SLACK_BOT_TOKEN environment variable as
the primary source, falling back to the X-Slack-Bot-Token header for
backwards compatibility. Logs a warning when using the header fallback to
help identify when infrastructure hasn't been updated yet.

Remove the backwards-compatibility fallback that read the Slack bot
token from the X-Slack-Bot-Token request header when the SLACK_BOT_TOKEN
env var was not set. The previous implementation was in beta, so no
transition period is needed. The token should only exist as an
environment variable.

- Simplify getSlackBotToken() to only read process.env.SLACK_BOT_TOKEN
- Remove header fallback logic and warning log
- Remove 3 fallback-related tests, add env-var-missing test
- Update SlackChatAdapter warning to reference env var instead of header
- Update changelogs to reflect no-fallback behavior
