Error handlers in execute_task, fix_skill, and upload_skill returned
traceback.format_exc() to MCP clients, exposing internal file paths,
code structure, and potentially sensitive details. The full traceback
is already logged server-side via logger.error(exc_info=True).
Remove the traceback field from client-facing error responses and
clean up the unused traceback import.

When the LLM returns a short tool name that doesn't match the deduped
key in tool_map, the fallback scan correctly resolves tool_obj via
schema.name. However the execution branch still checked
`tool_name not in tool_map` and passed `tool_map[tool_name]`, so
fallback-resolved tools were never executed.
Change the condition to check `tool_obj is None` and pass `tool_obj`
directly to _execute_tool_call.

__main__.py calls Logger.set_level(args.log_level) when --log-level
is passed, but the method did not exist on Logger, causing an
AttributeError. Add set_level(level: str) that resolves the name
to a logging constant and reconfigures via configure(force=True).

ErrorCode is a str Enum whose members are not callable. Calling
`raise ErrorCode.SESSION_NOT_FOUND(name)` produces a TypeError
instead of the intended session-not-found error. Replace all 5
occurrences with `raise GroundingError(..., code=ErrorCode.SESSION_NOT_FOUND)`.

- Forward resolved max_iterations to grounding agent in no-skill execution path
- Use hash-based workflow ID to prevent collision across roots and separator ambiguity

The previous __-joined scheme was not injective: a directory named
a__b and a nested path a/b both mapped to the same ID. Use a sha256
hash suffix of the resolved path instead, which is collision-free
and keeps the dir name as a human-readable prefix.
Added regression test for separator collision case.
workflow_dir.name was used as the discovery key and API ID, so two
different WORKFLOW_ROOTS containing a leaf directory with the same
name would silently drop one. Use root name + relative path joined
with __ as a stable unique ID instead.

Without this, the no-skill path ignores the resolved max_iterations
and uses whatever default the agent has, instead of the configured
grounding_max_iterations value.

Add a new MCP tool that bridges the gap between fully automatic
evolution (inside execute_task) and manual repair (fix_skill).
scan_evolution_opportunities lets host agents proactively inspect
which skills could benefit from evolution by:
1. Loading execution analyses marked as evolution candidates
2. Enriching each with SkillRecord usage statistics (completion
rate, fallback rate, effective rate)
3. Returning a structured JSON report with prioritized suggestions
This enables an "agent-in-the-loop" evolution pattern for all host
agents (Claude Code, Codex, nanobot, Cursor, etc.): periodic scan,
review report, selectively apply fixes.
Closes#24
Made-with: Cursor
- Add resolve() + is_relative_to() check in _extract_zip() to block
nested traversal entries like nested/../../escape.txt
- Sanitize server-provided skill name in import_skill() to prevent
directory escape via malicious record metadata
- Add 6 regression tests covering both attack vectors

Versions 1.82.7 and 1.82.8 of litellm were published on March 24, 2026
and contained malicious code that exfiltrated credentials (SSH keys,
cloud credentials, .env files, API keys) to an attacker-controlled domain.
Pin the dependency to >=1.70.0,<1.82.7 in both pyproject.toml and
requirements.txt as a stopgap until litellm can be replaced with direct
provider SDK calls.

Ref: PYSEC-2026-2, BerriAI/litellm#24521
Fixes#29. When a skill is already registered, register_skill_dir()
returned None, which caused fix_skill() to incorrectly report a failure.
Now returns the existing SkillMeta instead of None when the skill_id
is already present in the registry, making register_skill_dir() truly
idempotent as its callers (fix_skill, _auto_register_skill_dirs) expect.
Per reviewer feedback: keep strict \byes\b / \bno\b word boundaries to
prevent false positives, but widen confirm/reject/skip to stem-style
\bconfirm\w*\b etc. so common LLM variants like "confirmed", "rejected",
"skipping" still parse correctly instead of falling through to the
default False path.
