From b2ce1dd2e0808a7a09fbeedbcf6464e8ca4c1cbd Mon Sep 17 00:00:00 2001 From: warren <311177657+warren-run-bot@users.noreply.github.com> Date: Mon, 31 Aug 2026 20:46:45 +0000 Subject: [PATCH 1/7] fix(llms): strip cache_breakpoint from LiteLLM messages Strip provider-unsupported cache_breakpoint keys from messages before sending to LiteLLM. Native providers (OpenAI, Anthropic, etc.) already strip these markers in BaseLLM._format_messages(), but the LiteLLM path in LLM._format_messages_for_provider() was bypassing that cleanup, causing Mistral API to reject requests with 'extra_forbidden' errors. The fix ensures cache_breakpoint is stripped in all LiteLLM flows while preserving the marker for native providers that translate it to their cache directives (e.g., Anthropic's cache_control).

Be concise.\n\nWorkspace map:\n- The project repo is mounted at the burrow workspace root.\n- /workspace/.warren/agent.json is the rendered agent definition (warren seeded it).\n\nOperating contract:\n- Edit files in place. Run tests when relevant.\n- Quality gates are terminal, not advisory. You are NOT done until the gate exits zero. Resolve the command in this order: `$WARREN_QUALITY_GATE` if set, otherwise the command documented in CLAUDE.md / AGENTS.md, otherwise discover the project's own test and lint commands (package.json scripts, Makefile targets, CI config) and run those. Run it before committing and again before reporting completion. Do not declare the task complete, hand off, or end the session with a red gate — fix failures (including lint warnings, which CI treats as errors) until it is green. If the gate is genuinely unfixable in this run, say so explicitly and leave the work open rather than claiming success.\n- Use git as you normally would. Commit your changes; warren reaps the branch and pushes upstream.\n- Committing is mandatory, not the same as staging. `git add` ALONE IS NOT ENOUGH — you must run `git commit` so the work lands as a real commit. A run that ends with staged-but-uncommitted changes is treated as a FAILURE (`dropped_commit`), not a success. Before you report completion, run `git status`/`git log` and confirm your changes are in a commit, not just staged. The only exception is when you have genuinely made no file changes at all.\n- Do not run `git push` yourself — warren handles the push host-side after the run terminates.\n\n---\n\nWork on CrewAI GitHub issue #6789: with the native Mistral API (e.g. model mistral/mistral-large-latest), a direct llm.call() works, but Agent execution through crew.kickoff() fails with litellm.BadRequestError — the request body carries a `cache_breakpoint` key inside message objects (both system and user), and api.mistral.ai rejects it with 'extra_forbidden: Extra inputs are not permitted'. The bug is in the Agent execution path (message preparation for call_llm_native_tools), which injects prompt-cache metadata that only some providers accept. Fix message preparation so provider-unsupported keys like cache_breakpoint are never sent to the native Mistral API — strip or gate them by provider capability — while preserving current behavior for providers that do support prompt caching. Add focused tests proving Mistral-bound messages carry no cache_breakpoint and cache-supporting providers keep theirs. The package source lives under lib/crewai/src/crewai/ and its tests under lib/crewai/tests/. COMMIT DISCIPLINE (critical): commit your work with git as soon as each coherent change compiles, BEFORE running any validation, and keep committing incrementally — never leave completed work uncommitted while a long command runs. VALIDATION DISCIPLINE (critical): validation must be scoped and bounded. Run only the focused test files for the code you changed with 'uv run pytest -x -q' — never repo-wide commands: no full pytest run, no pre-commit run --all-files, no repo-wide type-checker sweep. Give every shell command an explicit timeout of at most 600 seconds; if a scoped test cannot finish in that budget, record that in your summary instead of waiting. Follow the repository's contribution rules strictly: the smallest possible diff, behavior-focused tests, Conventional Commits style for every commit message (e.g. fix(llms): ...), no refactor-only changes, no unrelated edits, and do not touch docs/v*/, docs/images/, uv.lock, pyproject.toml, .github/, or LICENSE. In your final summary, record exactly which commands you ran and their results as evidence.\n\n--- BEGIN AGENT GUIDANCE (repository policy agentGuidance v1) ---\nThe repository policy binds the following contribution norms. They are binding for this run:\n1. Produce the smallest possible diff that resolves the issue; scope changes to what the reviewed issue actually requires.\n2. Write behavior-focused unit tests for the fix: assert observable behavior, never implementation details.\n3. Never stringify LLMMessage.content with str(); collapse message content to text with the message_content_text helper from crewai.utilities.agent_utils.\n4. Never modify files under docs/v*/ or docs/images/ — those are frozen release snapshots managed by devtools; current docs live under docs/edge/en/ and register in docs/docs.json.\n5. Use Conventional Commits for every commit message and the PR title (feat|fix|docs|refactor|perf|test|chore with a scope), for example fix(llms): map default context window.\n6. Run the repository's own gates before finishing: uv run pytest on the touched test files, plus the configured pre-commit hooks; keep changes DRY and YAGNI.\n7. State unprovable claims as known gaps rather than omitting them; silent omissions are harder for review to catch than declared uncertainty.\n--- END AGENT GUIDANCE ---"}],"timestamp":1788209044415}} +{"type":"message","id":"b3b4bdae","parentId":"ddbceea2","timestamp":"2026-08-31T20:44:13.948Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"Let me break down the task:\n\n1.

Tests confirm: - Mistral models have markers stripped - Generic LiteLLM models have markers stripped - Original message list is not mutated - All other message keys are preserved Tests use object.__new__(LLM) to bypass __new__ validation and avoid requiring LiteLLM installation. Also make Anthropic tests conditional on provider availability.

Be concise.\n- /workspace/.warren/agent.json is the rendered agent definition (warren seeded it).\n- Quality gates are terminal, not advisory. You are NOT done until the gate exits zero. Resolve the command in this order: `$WARREN_QUALITY_GATE` if set, otherwise the command documented in CLAUDE.md / AGENTS.md, otherwise discover the project's own test and lint commands (package.json scripts, Makefile targets, CI config) and run those. Run it before committing and again before reporting completion. Do not declare the task complete, hand off, or end the session with a red gate — fix failures (including lint warnings, which CI treats as errors) until it is green. If the gate is genuinely unfixable in this run, say so explicitly and leave the work open rather than claiming success.\n- Use git as you normally would. Commit your changes; warren reaps the branch and pushes upstream.\n- Do not run `git push` yourself — warren handles the push host-side after the run terminates.\nWork on CrewAI GitHub issue #6789: with the native Mistral API (e.g. model mistral/mistral-large-latest), a direct llm.call() works, but Agent execution through crew.kickoff() fails with litellm.BadRequestError — the request body carries a `cache_breakpoint` key inside message objects (both system and user), and api.mistral.ai rejects it with 'extra_forbidden: Extra inputs are not permitted'. The bug is in the Agent execution path (message preparation for call_llm_native_tools), which injects prompt-cache metadata that only some providers accept. Fix message preparation so provider-unsupported keys like cache_breakpoint are never sent to the native Mistral API — strip or gate them by provider capability — while preserving current behavior for providers that do support prompt caching. Add focused tests proving Mistral-bound messages carry no cache_breakpoint and cache-supporting providers keep theirs. The package source lives under lib/crewai/src/crewai/ and its tests under lib/crewai/tests/. COMMIT DISCIPLINE (critical): commit your work with git as soon as each coherent change compiles, BEFORE running any validation, and keep committing incrementally — never leave completed work uncommitted while a long command runs. VALIDATION DISCIPLINE (critical): validation must be scoped and bounded. Run only the focused test files for the code you changed with 'uv run pytest -x -q' — never repo-wide commands: no full pytest run, no pre-commit run --all-files, no repo-wide type-checker sweep. Give every shell command an explicit timeout of at most 600 seconds; if a scoped test cannot finish in that budget, record that in your summary instead of waiting. Follow the repository's contribution rules strictly: the smallest possible diff, behavior-focused tests, Conventional Commits style for every commit message (e.g. fix(llms): ...), no refactor-only changes, no unrelated edits, and do not touch docs/v*/, docs/images/, uv.lock, pyproject.toml, .github/, or LICENSE. In your final summary, record exactly which commands you ran and their results as evidence.\n6. Run the repository's own gates before finishing: uv run pytest on the touched test files, plus the configured pre-commit hooks; keep changes DRY and YAGNI.\nWARREN_RUN_ID=run_zp2t6219v894\nWARREN_AGENT_RUN_AS_UID=1001\nGIT_COMMITTER_NAME=warren\nWARREN_BASE_BRANCH=main\nWARREN_BRANCH=warren/run_zp2t6219v894\nWARREN_API_URL=http://warren.warren.svc.cluster.local:8080\nGIT_AUTHOR_EMAIL=311177657+warren-run-bot@users.noreply.github.com\nGIT_COMMITTER_EMAIL=311177657+warren-run-bot@users.noreply.github.com\nWARREN_API_TOKEN=wrs1.run_zp2t6219v894.b318701adeaeba5a08c00a24cf3cb45515b3fe513798c2a58a645ab379991880\nnpm_package_name=@os-eco/warren-cli\nWARREN_AGENT_METADATA={\"frontmatter\":{\"tags\":[\"agent\"],\"model\":\"claude-sonnet-4-5\",\"source\":\"builtin\",\"runtime\":\"pi\",\"provider\":\"anthropic\",\"steering\":\"spawn-only\",\"maxCostUsd\":8}}\nWARREN_AGENT_RUNTIME=pi\n"}],"isError":false,"timestamp":1788209578593}} +{"type":"message","id":"cf779428","parentId":"1524a414","timestamp":"2026-08-31T20:53:01.405Z","message":{"role":"assistant","content":[{"type":"text","text":"No WARREN_QUALITY_GATE variable set.

Run tests when relevant.\n- Quality gates are terminal, not advisory. You are NOT done until the gate exits zero. Resolve the command in this order: `$WARREN_QUALITY_GATE` if set, otherwise the command documented in CLAUDE.md / AGENTS.md, otherwise discover the project's own test and lint commands (package.json scripts, Makefile targets, CI config) and run those. Run it before committing and again before reporting completion. Do not declare the task complete, hand off, or end the session with a red gate — fix failures (including lint warnings, which CI treats as errors) until it is green. If the gate is genuinely unfixable in this run, say so explicitly and leave the work open rather than claiming success.\n- Use git as you normally would. Commit your changes; warren reaps the branch and pushes upstream.\n- Committing is mandatory, not the same as staging. `git add` ALONE IS NOT ENOUGH — you must run `git commit` so the work lands as a real commit. A run that ends with staged-but-uncommitted changes is treated as a FAILURE (`dropped_commit`), not a success. Before you report completion, run `git status`/`git log` and confirm your changes are in a commit, not just staged. The only exception is when you have genuinely made no file changes at all.\n- Do not run `git push` yourself — warren handles the push host-side after the run terminates.\n\n---\n\nWork on CrewAI GitHub issue #6789: with the native Mistral API (e.g. model mistral/mistral-large-latest), a direct llm.call() works, but Agent execution through crew.kickoff() fails with litellm.BadRequestError — the request body carries a `cache_breakpoint` key inside message objects (both system and user), and api.mistral.ai rejects it with 'extra_forbidden: Extra inputs are not permitted'. The bug is in the Agent execution path (message preparation for call_llm_native_tools), which injects prompt-cache metadata that only some providers accept. Fix message preparation so provider-unsupported keys like cache_breakpoint are never sent to the native Mistral API — strip or gate them by provider capability — while preserving current behavior for providers that do support prompt caching. Add focused tests proving Mistral-bound messages carry no cache_breakpoint and cache-supporting providers keep theirs. The package source lives under lib/crewai/src/crewai/ and its tests under lib/crewai/tests/. COMMIT DISCIPLINE (critical): commit your work with git as soon as each coherent change compiles, BEFORE running any validation, and keep committing incrementally — never leave completed work uncommitted while a long command runs. VALIDATION DISCIPLINE (critical): validation must be scoped and bounded. Run only the focused test files for the code you changed with 'uv run pytest -x -q' — never repo-wide commands: no full pytest run, no pre-commit run --all-files, no repo-wide type-checker sweep. Give every shell command an explicit timeout of at most 600 seconds; if a scoped test cannot finish in that budget, record that in your summary instead of waiting. Follow the repository's contribution rules strictly: the smallest possible diff, behavior-focused tests, Conventional Commits style for every commit message (e.g. fix(llms): ...), no refactor-only changes, no unrelated edits, and do not touch docs/v*/, docs/images/, uv.lock, pyproject.toml, .github/, or LICENSE. In your final summary, record exactly which commands you ran and their results as evidence.\n\n--- BEGIN AGENT GUIDANCE (repository policy agentGuidance v1) ---\nThe repository policy binds the following contribution norms. They are binding for this run:\n1. Produce the smallest possible diff that resolves the issue; scope changes to what the reviewed issue actually requires.\n2. Write behavior-focused unit tests for the fix: assert observable behavior, never implementation details.\n3. Never stringify LLMMessage.content with str(); collapse message content to text with the message_content_text helper from crewai.utilities.agent_utils.\n4. Never modify files under docs/v*/ or docs/images/ — those are frozen release snapshots managed by devtools; current docs live under docs/edge/en/ and register in docs/docs.json.\n5. Use Conventional Commits for every commit message and the PR title (feat|fix|docs|refactor|perf|test|chore with a scope), for example fix(llms): map default context window.\n6. Run the repository's own gates before finishing: uv run pytest on the touched test files, plus the configured pre-commit hooks; keep changes DRY and YAGNI.\n7. State unprovable claims as known gaps rather than omitting them; silent omissions are harder for review to catch than declared uncertainty.\n--- END AGENT GUIDANCE ---"}],"timestamp":1788209044415}} -{"type":"message","id":"b3b4bdae","parentId":"ddbceea2","timestamp":"2026-08-31T20:44:13.948Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"Let me break down the task:\n\n1.

Be concise.\n- /workspace/.warren/agent.json is the rendered agent definition (warren seeded it).\n- Quality gates are terminal, not advisory. You are NOT done until the gate exits zero. Resolve the command in this order: `$WARREN_QUALITY_GATE` if set, otherwise the command documented in CLAUDE.md / AGENTS.md, otherwise discover the project's own test and lint commands (package.json scripts, Makefile targets, CI config) and run those. Run it before committing and again before reporting completion. Do not declare the task complete, hand off, or end the session with a red gate — fix failures (including lint warnings, which CI treats as errors) until it is green. If the gate is genuinely unfixable in this run, say so explicitly and leave the work open rather than claiming success.\n- Use git as you normally would. Commit your changes; warren reaps the branch and pushes upstream.\n- Do not run `git push` yourself — warren handles the push host-side after the run terminates.\nWork on CrewAI GitHub issue #6789: with the native Mistral API (e.g. model mistral/mistral-large-latest), a direct llm.call() works, but Agent execution through crew.kickoff() fails with litellm.BadRequestError — the request body carries a `cache_breakpoint` key inside message objects (both system and user), and api.mistral.ai rejects it with 'extra_forbidden: Extra inputs are not permitted'. The bug is in the Agent execution path (message preparation for call_llm_native_tools), which injects prompt-cache metadata that only some providers accept. Fix message preparation so provider-unsupported keys like cache_breakpoint are never sent to the native Mistral API — strip or gate them by provider capability — while preserving current behavior for providers that do support prompt caching. Add focused tests proving Mistral-bound messages carry no cache_breakpoint and cache-supporting providers keep theirs. The package source lives under lib/crewai/src/crewai/ and its tests under lib/crewai/tests/. COMMIT DISCIPLINE (critical): commit your work with git as soon as each coherent change compiles, BEFORE running any validation, and keep committing incrementally — never leave completed work uncommitted while a long command runs. VALIDATION DISCIPLINE (critical): validation must be scoped and bounded. Run only the focused test files for the code you changed with 'uv run pytest -x -q' — never repo-wide commands: no full pytest run, no pre-commit run --all-files, no repo-wide type-checker sweep. Give every shell command an explicit timeout of at most 600 seconds; if a scoped test cannot finish in that budget, record that in your summary instead of waiting. Follow the repository's contribution rules strictly: the smallest possible diff, behavior-focused tests, Conventional Commits style for every commit message (e.g. fix(llms): ...), no refactor-only changes, no unrelated edits, and do not touch docs/v*/, docs/images/, uv.lock, pyproject.toml, .github/, or LICENSE. In your final summary, record exactly which commands you ran and their results as evidence.\n6. Run the repository's own gates before finishing: uv run pytest on the touched test files, plus the configured pre-commit hooks; keep changes DRY and YAGNI.\nWARREN_RUN_ID=run_zp2t6219v894\nWARREN_AGENT_RUN_AS_UID=1001\nGIT_COMMITTER_NAME=warren\nWARREN_BASE_BRANCH=main\nWARREN_BRANCH=warren/run_zp2t6219v894\nWARREN_API_URL=http://warren.warren.svc.cluster.local:8080\nGIT_AUTHOR_EMAIL=311177657+warren-run-bot@users.noreply.github.com\nGIT_COMMITTER_EMAIL=311177657+warren-run-bot@users.noreply.github.com\nWARREN_API_TOKEN=wrs1.run_zp2t6219v894.b318701adeaeba5a08c00a24cf3cb45515b3fe513798c2a58a645ab379991880\nnpm_package_name=@os-eco/warren-cli\nWARREN_AGENT_METADATA={\"frontmatter\":{\"tags\":[\"agent\"],\"model\":\"claude-sonnet-4-5\",\"source\":\"builtin\",\"runtime\":\"pi\",\"provider\":\"anthropic\",\"steering\":\"spawn-only\",\"maxCostUsd\":8}}\nWARREN_AGENT_RUNTIME=pi\n"}],"isError":false,"timestamp":1788209578593}} -{"type":"message","id":"cf779428","parentId":"1524a414","timestamp":"2026-08-31T20:53:01.405Z","message":{"role":"assistant","content":[{"type":"text","text":"No WARREN_QUALITY_GATE variable set.

LLM inherits from BaseModel, so bypassing __new__ and directly assigning fields can raise AttributeError before the test methods run. This change introduces a test-only _LLMForTest subclass that overrides __new__ to allow model_construct() to work properly, providing a more idiomatic and safer way to instantiate test instances for testing internal methods like _format_messages_for_provider().
