Adds a budget package that estimates token usage and progressively
trims context to fit within model-specific limits.
Trim order (least important first):
1. Language patterns
2. Repository conventions
3. Full file context
4. Diff (truncated as last resort)
When content is trimmed, a note is appended to the user prompt so
the LLM knows context was reduced.
- New budget package with Fit(), EstimateTokens(), LimitForModel()
- Model limit table (GPT-4.1: 128K, GPT-5: 200K, Claude: 200K)
- Refactored review/prompt.go: BuildSystemBase() and BuildUserMeta()
extract non-trimmable content; old functions delegate to new ones
- main.go uses budget.Fit() instead of direct prompt assembly
- 7 unit tests covering all trim paths
Closes#19
- Add --version flag and log version on startup (closes#9)
- URL-escape ref query parameter in GetFileContentRef (closes#7)
- Add go vet to release workflow (closes#13)
Renamed local url variable to reqURL to avoid shadowing net/url package.
- Overall context timeout now derived from LLM timeout + 1 minute
(no longer hardcoded 3min that could conflict with longer LLM timeouts)
- Clarify concurrency docs: With* methods are setup-only, not concurrent
- Add ctx.Err() checks in fetchFileContext and fetchPatterns loops
(break early on cancellation instead of making unnecessary requests)
- Fix doc comments: WithTimeout and WithTemperature each get their own
- Add TestWithTimeout (verifies short timeout causes request failure)
- Log warning on directory recursion failure in GetAllFilesInPath
- Note: unexported fields is a breaking change, will document in release notes
New flag: --llm-timeout / LLM_TIMEOUT (seconds, default 300)
New builder: llmClient.WithTimeout(duration)
Composite action: new timeout input
Keeps 5 minutes as the sensible default but allows tuning for
larger repos or slower models.
- GetAllFilesInPath: log.Printf when file fetch or dir recursion fails
- integration_test: use strings.SplitN for owner/repo parsing (idiomatic)
Addresses GPT review findings #1, #2.
REVIEW.md findings 1-4, 14:
- All Gitea client methods now accept context.Context as first param
- All LLM client methods now accept context.Context as first param
- Use http.NewRequestWithContext for cancellation/timeout support
- Main uses 3-minute timeout context for all operations
- Unexport Client struct fields (baseURL, token, apiKey, etc.)
- Use bytes.NewReader instead of strings.NewReader(string(...))
patterns-repo now accepts a comma-separated list of repos:
PATTERNS_REPO="rodin/elixir-patterns,rodin/phoenix-conventions"
patterns-files accepts files AND directories:
PATTERNS_FILES="README.md,docs/"
When a path is a directory, all files within it are fetched
recursively via the Gitea contents API. Only .md, .txt, .yml,
and .yaml files are included as pattern content.
New API methods:
- ListContents: list files/dirs at a path via contents API
- GetAllFilesInPath: recursively fetch all file contents
This allows a single review action to pull idioms from multiple
pattern repos (e.g. elixir-patterns + phoenix-conventions) and
include entire directories of documentation as review criteria.
Major improvements to review quality:
1. Full file context: fetch complete content of all modified files from
the PR branch and include as reference. This eliminates false-positive
"missing import" findings since the model sees the entire file.
2. Patterns repo: new --patterns-repo / PATTERNS_REPO flag fetches
language idiom files from a separate Gitea repo (e.g. rodin/elixir-patterns)
and includes them as review criteria.
3. Multi-file patterns: --patterns-files / PATTERNS_FILES accepts
comma-separated file paths to fetch from the patterns repo.
New API methods:
- GetPullRequestFiles: list changed files in a PR
- GetFileContentRef: fetch file content from a specific branch/ref
Prompt changes:
- BuildSystemPrompt now accepts (conventions, patterns)
- BuildUserPrompt now accepts fileContext parameter
- File context displayed before diff for model reference
- Patterns presented as "review criteria" in system prompt
Composite action updated with patterns-repo and patterns-files inputs.
The LLM was treating the diff as complete file context and flagging
"missing imports" for symbols that exist in unchanged portions of
the file. Added explicit instructions to the system prompt:
- Clarify that the diff is partial; unchanged code already exists
- Explicitly instruct: do not flag missing imports/types unless the
diff introduces a new usage without a corresponding addition
- Add rule: never flag undefined symbols that could exist in the
unchanged portions
- Add temperature range validation (must be 0-2, fatal on invalid)
- release.yml: use python3 for robust JSON parsing instead of sed
- Composite action: add header comment confirming Gitea Actions compat
- All findings from review #385 addressed
- Composite action: cache to runner.temp instead of /usr/local/bin
(avoids permission issues on runners)
- Document that temperature=0 means server default (omitted from request)
- Note: strconv import already exists (false positive from GPT-5)
- .gitea/actions/review/action.yml: composite action with caching
Consumers just use:
uses: https://gitea.weiker.me/rodin/review-bot/.gitea/actions/review@v0.1.0
No Go toolchain needed, binary cached by version tag.
- Remove install.sh (replaced by composite action)
- CI workflow: use matrix strategy to parallelize reviews
- Self-review still builds from source (pre-release)
- install.sh: verify SHA-256 checksum before installing binary
- install.sh: fallback to ~/.local/bin if /usr/local/bin not writable
- install.sh: use sed instead of grep for POSIX-safe JSON parsing
- release.yml: remove jq dependency, parse release ID with sed
- llm: make temperature configurable via --llm-temperature / LLM_TEMPERATURE
- llm: add WithTemperature builder method on Client
- llm: omit temperature from request when zero (uses server default)
HAI proxy serves Anthropic on a different path (/anthropic/v1) than
OpenAI (/openai/v1). Until review-bot supports multiple base URLs,
use GPT-5 and GPT-5-mini for both review slots.
- Release workflow: builds linux/darwin amd64/arm64 on tag push
- Injects version via -ldflags
- Creates Gitea release with binary assets + checksums
- install.sh: curl-pipe-bash installer from latest release
- Version variable in main.go for -version flag support
- CLI binary with flag/env var configuration
- Gitea API client (PR metadata, diff, CI status, post review)
- OpenAI-compatible LLM client
- Structured review prompt with conventions support
- JSON response parser with validation
- Markdown review formatter for Gitea
- CI failure auto-detection (REQUEST_CHANGES)
- Dry-run mode for testing
