MAJOR fixes:
- Remove external YAML dependency (github.com/goccy/go-yaml)
Per project convention: Go standard library only, zero dependencies.
Convert all persona files from YAML to JSON format.
- Fix TestValidateWorkspacePath error expectation
Go 1.21+ filepath.Join normalizes absolute paths differently.
MINOR fixes:
- Remove custom contains helper in persona_test.go (use strings.Contains)
- Add Unicode-safe CapitalizeFirst function for header titles
- ListBuiltinPersonas returns empty slice instead of nil on error
- Fix test comment about filepath.Join behavior
Documentation:
- Update README to reflect JSON-only persona format
- Update design doc with note about JSON decision
- Fix action.yml description for persona-file input
Add persona system for specialized review roles. Each persona defines:
- A specific review focus (security, architecture, documentation)
- Custom system prompt additions
- Personality/tone adjustments
Built-in personas: security, architect, docs
Custom personas: load from JSON via persona-file flag
Includes workspace validation to prevent path traversal attacks.
Closes#51
When a PR is pushed after being marked self-reviewed, the label is now
stale and should be removed. This matches the gargoyle CI behavior.
On synchronize:
- Remove self-reviewed label if present
- Reassign PR back to the author
- Restore sonnet reviewer with correct model name (anthropic--claude-4.6-sonnet)
- Remove gpt-4.1, gpt-4.1-mini, gpt-5-mini (not deployed on SAP AI Core)
- Keep gpt-5 and security reviewers
The previous model names (claude-sonnet-4-6, etc.) were incorrect —
SAP AI Core uses 'anthropic--claude-4.6-sonnet' format.
Models claude-sonnet-4-6, gpt-4.1, gpt-4.1-mini, and gpt-5-mini are not
deployed on the LLM proxy, causing 502 errors. Keep only gpt-5 which
is the only available model.
When a new push arrives while review-bot is processing, the review
would be posted against a stale commit. This causes noise in the
PR timeline with findings that reference code that no longer exists.
Before posting, re-fetch PR metadata and compare HEAD SHA with the
commit we evaluated against. If they differ, log a warning and exit
successfully — a new workflow run should already be processing the
new HEAD.
Fixes#52
Addresses intermittent 'unexpected end of JSON input' failures where the
LLM response body is truncated in transit between the proxy and client.
Root cause: network-level truncation where io.ReadAll returns partial data
(observed in 3/50 CI runs through HAI proxy). The response body reading
was already using io.ReadAll correctly, but transient network issues
between the proxy and client can still cause partial reads.
Changes:
- Add Content-Length validation in doRequest: detect when fewer bytes
arrive than the server declared, triggering a retry
- Add retry logic in Complete: retries once on retryable errors (body
read failures, content-length mismatches) with a 500ms backoff
- Add parse-level retry in main: if ParseResponse fails, re-requests
from the LLM once before giving up (defensive, since retries always
succeed per issue evidence)
- Improve ParseResponse error diagnostics: log raw vs cleaned lengths
and a preview of the cleaned content to aid future debugging
Does NOT retry on API errors (4xx/5xx) or structural issues — only
transient body read problems.
Closes#47
- Fix token_secret for gpt41/gpt5-mini/gpt41-mini: use GPT_REVIEW_TOKEN
instead of SONNET_REVIEW_TOKEN (wrong reviewer identity)
- Move LLM base URL back to secrets.LLM_BASE_URL (prevents exfiltration
via PR-controlled matrix values)
- Remove hardcoded internal IP from workflow file; only provider path
suffix (/anthropic/v1, /openai/v1) remains in matrix
Addresses: security-review-bot REQUEST_CHANGES (major: exfiltration risk,
minor: HTTP/hardcoded IP) and sonnet-review-bot REQUEST_CHANGES (major:
wrong token_secret on gpt entries).
The matrix was wrong: "sonnet" was running GPT-5 and "gpt" was running
GPT-4.1. Now:
- sonnet → Claude Sonnet 4.6 via HAI Anthropic endpoint
- gpt → GPT-5 via HAI OpenAI endpoint
- security → GPT-5 via HAI OpenAI endpoint
Each matrix entry specifies its own provider and base_url.
Previously findOwnReview returned only the single most-recent matching
review, so on PRs with multiple force-pushes only the latest old review
got superseded. The rest accumulated as unsuperseded stale reviews.
Changes:
- Add findAllOwnReviews() to collect all non-superseded matching reviews
- Loop over all old reviews in the supersede phase
- Add GetTimelineReviewCommentIDForReview() to find comment IDs by
review ID (fetches review body, matches in timeline by prefix)
- Each old review gets independently superseded and its inline comments
resolved
The old findOwnReview is kept for backward compat (tested, may be
useful as a utility).
Closes#27
After superseding an old review, resolves all its inline comments via
POST /pulls/comments/{id}/resolve. This clears unresolved conversation
markers from the PR timeline and diff view.
New API methods:
- ListReviewComments: paginated GET /repos/.../pulls/{n}/reviews/{id}/comments
- ResolveComment: POST /repos/.../pulls/comments/{id}/resolve
Behavior:
- Only resolves after successful supersede (gated on supersedeOK)
- Aggregates failures and logs at warn level
- Truncates error bodies to 256 bytes (security)
- Non-fatal: review still posts even if resolution fails
- Accept 204 No Content as success (idempotent operations)
- Truncate error response body to 256 bytes (prevent log leakage)
- Add unit tests for GetAuthenticatedUser and RequestReviewer
Closes#35
Before posting a review, the bot:
1. Discovers its own Gitea login via GET /user
2. Calls POST /requested_reviewers to add itself
This ensures the bot appears in the required-reviewers list without
manual configuration on the repo. The call is idempotent (no-op if
already requested).
Both failures are non-fatal (warn + continue) — the review still posts
even if the self-request fails.
Changes the order of operations:
1. POST new review (gets non-stale badge immediately)
2. PATCH old review with superseded message linking to the new one
This gives the superseded comment a clickable link to the current
review, making navigation between review iterations easy.
buildSupersededBody now accepts a newReviewURL parameter.
The strict authorship check compared reviewer-name to User.Login which
could mismatch. The sentinel is already role-specific (e.g.
<!-- review-bot:sonnet -->) and Gitea's API blocks editing others'
comments (403). Defense-in-depth via login comparison is unnecessary
complexity that introduced a bug. Removed.
Closes#34
- Remove reviewUnchanged() skip logic — every push gets a fresh review
- Remove edit-in-place (PATCH same body) — always POST new
- Supersede old review: PATCH with struck-through banner + collapsed
original body in <details> for historical reference
- Add commit footer to every review: 'Evaluated against <sha>'
- Remove --update-existing flag (no longer needed)
- Add CommitID field to Review struct
- Add TestBuildSupersededBody tests
- Add --log-format flag (text/json) and --verbosity flag (debug/info/warn/error)
- Replace all log.Printf with slog.Info/Debug/Warn with structured key-value attrs
- Replace all log.Fatalf with slog.Error + os.Exit(1)
- Convert gitea/client.go warnings to slog.Warn
- Add comprehensive tests for logger initialization and level filtering
Closes#23
Partially addresses #32
Add a Runner Requirements section to the README documenting that
the composite action needs python3, sha256sum, and curl on the
runner. All are pre-installed on ubuntu-* runners but custom
images need to provide them.
Closes#12
- URL-encode filename in release upload query param (MINOR)
- Truncate APIError.Body to 200 chars in Error() to avoid leaking
verbose server responses into logs (NIT)
- Add APIError type with StatusCode field so callers can inspect HTTP
status codes from Gitea API responses
- Add IsNotFound helper for ergonomic 404 checks
- GetAllFilesInPath now only falls back to single-file fetch on 404;
all other errors (auth failures, server errors, rate limits) propagate
- Release workflow asset uploads are now idempotent: existing assets
with the same name are deleted before re-upload on workflow re-runs
Closes#8Closes#10
The security-review-bot Gitea user now has its own token. This
completes the token separation so each reviewer role posts under
its own identity, enabling native Gitea multi-reviewer blocking.
When hasSharedToken() detects two roles sharing the same Gitea user,
the bot now skips ALL update logic (PATCH, supersede) and always POSTs
a fresh review. This prevents clobbering a sibling's review body or
state when misconfigured.
Tests now assert return values (true/false) rather than just verifying
no panic. Added additional test case for three-roles-same-user scenario.
Addresses review feedback: update logic and review state must not
interact with sibling reviews under the same user.
When two review-bot roles share the same Gitea user token (misconfiguration),
log a WARNING identifying which sibling is sharing. The bot continues normally
with its own honest verdict — no escalation, no deadlock. Operators see the
warning in CI logs and can fix the token setup.
Addresses Aaron's review feedback on #28: graceful degradation when someone
doesn't follow the separate-token deployment instructions.
