* fix: prevent futile retry loop when commit_and_open_pr fails with git/API errors
- Root cause: when git checkout or GitHub PR API fails, the tool returned a generic {"success": false} error with no signal that retrying is futile, causing the agent to loop 9-13+ times until hitting the 1000-step recursion limit
- Change: (1) git_checkout_branch now returns (bool, str) so the actual git error output is surfaced in the tool response; (2) checkout and PR creation failures now include "fatal": true and an explicit "Do not retry" message; (3) prompt.py COMMIT_PR_SECTION adds an explicit instruction to stop on fatal errors
- Verified: 109 unit tests pass, no regressions
* fix: skip PR safety net on fatal commit failures
* style(open_pr): ruff-format fatal retry skip condition

- Root cause: create_github_pr found an existing PR on 422 but never
PATCHed it, so callers like commit_and_open_pr could not update the
PR body (e.g. adding "Closes AB-1159") on subsequent invocations.
- Change: after _find_existing_pr succeeds, call new _update_github_pr
helper which PATCHes /repos/{owner}/{repo}/pulls/{number} with the
requested title and body before returning pr_existing=True.
- Verified: self-evident API call addition; proof in production traces.

- Root cause: httpx.HTTPError handler returned (None, None, False) without
checking if the PR was already created on GitHub before the network error
- Change: added _find_existing_pr fallback in except block in agent/utils/github.py
- Verified: 5 production traces showed false failures where PR existed (pr_existing=True on retry)

* fix: stop agent retrying commit_and_open_pr on 403 permission denied
Detect 403/permission-denied push failures in commit_and_open_pr and
return a PERMANENT_FAILURE message so the LLM stops retrying. Also add
prompt-level guidance to the COMMIT_PR_SECTION reinforcing this. Add
unit tests covering both the 403 and non-403 push failure paths.

* fix: stop safety net retrying permanent push failures
Skip the after-agent PR fallback when commit_and_open_pr reports a permanent GitHub push authorization failure, while preserving fallback behavior for recoverable failures.

Calling get_github_token() without arguments always invoked LangGraph get_config internally,
which broke tests that only patch agent.middleware.open_pr.get_config and failed outside
runnable context.
Extend get_github_token with an optional runnable config mapping; the middleware passes
the config dict already resolved from get_config(). Request GitHub App installation tokens
only after detecting sandbox/repo changes worth publishing.
Fixes failing Agent unit tests in tests/test_open_pr_middleware.py.
* feat: open PRs under user's name and add OpenSWE label
* feat: use user token for PR authorship, add OpenSWE label, and consolidate fallback logic
* linting
* fix: address review nits for PR authorship and labeling
Fix docstring casing, add debug logging for 422 existing-PR search
fallback, tighten test type annotations, and add missing HTTPError
fallback test.

* feat: default to GPT-5.5 medium reasoning
Use OpenAI GPT-5.5 with medium reasoning as the default model and document the completion-token budget semantics for reasoning models.
* fix: use Responses API reasoning config
Pass GPT-5.5 reasoning settings through LangChain's Responses API parameter instead of the Chat Completions-only reasoning_effort field.
* feat: raise GPT-5.5 output budget
Set the default GPT-5.5 output token budget to the model maximum so long-running coding tasks have more room for reasoning and final responses.
* feat: align recursion limit with Deep Agents
Use Deep Agents' default recursion limit so longer coding runs have room to complete without Open SWE imposing a lower cap.
* chore: remove minimal effort level
* chore: reduce max tokens to 64_000

* feat: migrate LangSmith sandbox creation to snapshot API
Replaces the template-based sandbox flow (DEFAULT_SANDBOX_TEMPLATE_NAME /
DEFAULT_SANDBOX_TEMPLATE_IMAGE) with the new snapshot-based flow.
- New required env var DEFAULT_SANDBOX_SNAPSHOT_ID (UUID of a pre-built
LangSmith snapshot; build out-of-band via UI or SandboxClient.create_snapshot)
- Optional DEFAULT_SANDBOX_SNAPSHOT_FS_CAPACITY_BYTES overrides the root FS
size at boot (default 32 GiB)
- Startup-time validation via a FastAPI lifespan hook: the server refuses
to boot with a clear ValueError if SANDBOX_TYPE=langsmith and
DEFAULT_SANDBOX_SNAPSHOT_ID is unset, so failures surface in boot logs
rather than on the first thread
- Reconnect-to-existing-sandbox path unchanged
- Docs (INSTALLATION.md, CUSTOMIZATION.md) updated to describe the new
snapshot workflow
* fix: format create_sandbox_snapshot.py to pass ruff

The agent sees users formatted as @Name(USER_ID) in conversation context and
reproduces that pattern in replies, but Slack requires <@USER_ID> for real
mentions. This adds automatic conversion and updates prompt instructions.

Adds 6 new agent tools backed by Linear's GraphQL API, with a shared
_graphql_request helper to reduce boilerplate. Refactors existing
comment_on_linear_issue to use the same helper.

* feat: extract repo parsing into shared util and add linear comment repo override
Moves the repo extraction regex logic (repo:, repo , GitHub URL) into
agent/utils/repo.py so it can be reused. Updates the Linear webhook
handler to check the comment body for a custom repo first, falling back
to the team/project mapping when none is specified.
* chore: document repo extraction util and default org configuration
* feat: add generic DEFAULT_REPO_OWNER/DEFAULT_REPO_NAME env vars replacing Slack-only defaults
* chore: remove deprecated SLACK_REPO_OWNER/NAME env vars from docs
