fix: harden network requests and gateway compatibility - #115
Harden web requests and improve OpenCode Free gateway compatibility, with patch releases prepared for all three affected packages.
Web search refuses provider redirects and suppresses untrusted error bodies to protect credentials and queries. Web fetch bounds concurrent acquisitions, closes unused responses, and avoids retrying sooner than a server requests. OpenCode Free discovers eligible Responses models and supports tool-free requests through the gateway while preventing compatibility-only tool calls from executing.
The branch also adds the Repo Assist workflow and streamlines readiness checks. Review the workflow permissions and automation alongside the network and gateway changes; release tags and publishing remain separate steps after merge.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The pull request adds Repo Assist workflow automation and routing guidance, removes the pi-coderabbit-skills package, and updates pi-opencode-free, pi-web-fetch, and pi-web-search. It also changes package validation, workflow compilation, and repository metadata.
Changes: Agentic workflow guidance
Layer / File(s)
Summary
Guidance routing and loading .github/skills/agentic-workflows/SKILL.md
Adds task routing to specialized workflow guidance, with rules for selecting, loading, and resolving local or remote guidance.
Repo Assist workflow
Layer / File(s)
Summary
Workflow setup and memory contract .github/workflows/repo-assist.md, .github/aw/actions-lock.json, .gitattributes, vite.config.ts
Adds workflow execution settings, output policies, and a validated memory schema. Marks the generated lock file for Linguist and formatting exclusion.
Task selection and run modes .github/workflows/repo-assist.md
Task execution and memory updates .github/workflows/repo-assist.md
Defines memory handling and task instructions for issue triage, fixes, maintenance, reporting, and repository work.
Compilation and workflow contracts scripts/compile-repo-assist.ts, docs/development.md, tests/repo-assist-contract.test.ts
Adds a compiler wrapper that validates and updates the memory-publication gate, documentation for compilation, and contract tests for workflow and safe-output rules.
CodeRabbit skills package removal
Layer / File(s)
Summary
Remove the skills package and references packages/pi-coderabbit-skills/*, README.md, tests/repository-contract.test.ts
Deletes the package manifest, skill content, supporting files, and root README entry. Repository package classification no longer includes the package.
pi-opencode-free 0.3.3
Layer / File(s)
Summary
Responses model discovery and release packages/pi-opencode-free/src/models.ts, packages/pi-opencode-free/tests/models.test.ts, packages/pi-opencode-free/package.json, packages/pi-opencode-free/CHANGELOG.md, packages/pi-opencode-free/README.md, docs/architecture.md
Model discovery accepts zero-cost OpenAI Responses entries and omits their compatibility metadata. Release metadata and documentation are updated.
Requests without tools receive a synthetic read declaration. Normalization ensures a usable first environment block. Tool calls from tool-free requests produce an error, and usage-limit text includes the upstream error tag.
Bun transport and test coverage packages/pi-opencode-free/src/bun-transport.ts, packages/pi-opencode-free/tests/bun-transport*.test.ts, packages/pi-opencode-free/tests/cli-version.test.ts
Missing Bun startup errors receive a dedicated message. Tests cover transport cancellation, streaming, child-process termination, and CLI version timeout behavior.
pi-web-fetch 0.16.4
Layer / File(s)
Summary
Acquisition limits and integration packages/pi-web-fetch/src/acquisition/*, packages/pi-web-fetch/tests/admission.test.ts, docs/architecture.md
A shared queue limits acquisitions to 16 active and 128 waiting requests. Fetch operations hold slots through response processing and release them on completion.
Discarded responses are destroyed. Retry handling honors server delays within the retry budget and returns the response without retrying when a delay exceeds that budget.
Provider requests reject redirects and report only HTTP status for unsuccessful responses. Response readers cancel oversized bodies and no longer return truncated content.
Repository packaging and release checks
Layer / File(s)
Summary
Package and release checks tests/package-smoke-test.ts, tests/repository-contract.test.ts, package.json
Package smoke tests reject invalid archive paths and check manifest coverage. The ready script no longer runs the package dry run, and release contract tests no longer require release-creation commands or names.

Before / after behavior
observed — Modified behavior in README.md: The package table entry for @zeldrisho/pi-coderabbit-skills, including its Skills type, review and autofix purpose, and install command, was removed.
observed — Modified behavior in docs/architecture.md: The documentation changes Retry-After handling from capped values to honoring advertised delays up to the retry budget; longer delays return the response without an early retry. It adds a process-wide acquisition queue capped at 16 active and 128 waiting, with deadlines and cancellation covering queueing and slots held through reading and extraction. Unused redirect and error bodies are destroyed rather than drained.
observed — Modified behavior in docs/architecture.md: The provider-request documentation adds that provider redirects are refused and untrusted HTTP error bodies are discarded without exposing their contents.
observed — Modified behavior in docs/architecture.md: The pi-opencode-free documentation adds discovery of zero-cost OpenAI chat and Responses catalog entries, specifies gateway chat translation for both, and states that Responses-specific compatibility flags are not forwarded to the chat adapter.

Review comments at @.github/skills/agentic-workflows/SKILL.md:
- Line 31: Update the 403 fallback instructions to preserve the requested ref
for public github/gh-aw content: build the raw.githubusercontent.com URL using
the resolved ref and repository-relative path, and use main only when no ref was
selected. Keep the restriction against sending authorization headers or tokens
to the raw URL.
- Line 152: Update the OTEL guidance instruction to reference
`.github/skills/otel-queries/SKILL.md` instead of
`skills/otel-queries/SKILL.md`, preserving the requirement to load it after the
matching workflow prompt or skill.
Review comments at @.github/workflows/repo-assist.md:
- Around line 29-30: Update the workflow-level concurrency configuration so all
runs that share repository memory use the same stable group instead of a
run-specific `github.run_id`; preserve serialization across scheduled and manual
runs.
- Line 466: Update the workflow logic around push_repo_memory so
action-dependent memory is persisted only after the corresponding safe_outputs
succeed; ensure safe_outputs failures, including capacity-check rejection,
cannot trigger persistence.
Review comments at @packages/pi-opencode-free/src/request.ts:
- Around line 114-145: Update ensureFirstEnvironment to search each instruction
message independently rather than joining their text before matching environment
blocks. Keep the existing first-block validation and usable-block selection
behavior, and derive the directory from a block contained entirely within one
message so tags split across messages cannot form a match.

Make the gate rewrite idempotent or fail with a clear message.
The wrapper requires exactly one occurrence of needs.agent.result != 'skipped' in the generated job. If a gh-aw upgrade changes the compiler output, the wrapper throws and restores the lock file. This fail-closed behavior is acceptable.
The error text is generic. It does not state which check failed: the safe_outputs dependency or the condition count. Report the failed check so maintainers can fix the wrapper faster after a gh-aw upgrade.

Prevent data loss in fallback instructions.
For bundle-backed updates, the pinned handler puts git reset --hard in the review issue’s apply instructions. If a maintainer follows them with unrelated tracked changes in the working tree, the reset discards those changes. Use a safe fallback implementation, or block these pushes until one is available.

When a PR update changes a protected file, the tool first reports success, but the handler later skips the push. The safe-output job can still succeed, so memory can record an update that never happened. (raw.githubusercontent.com)
