+## Summary
+
+Implements Issue #90 Tool Script Safety Guard as an opt-in pre-execution guard
+for Python and Bash tool scripts.
+
+## Issue #90 Acceptance Checklist
+
+- [ ] Scans script/command text, command-line arguments, cwd, env, and tool metadata.
+- [ ] Produces `allow`, `deny`, and `needs_human_review` decisions.
+- [ ] Supports Python and Bash scanners.
+- [ ] Supports YAML policy configuration, including strict validation.
+- [ ] Emits structured reports with decision, risk type, rule, evidence, and recommendation.
+- [ ] Writes sanitized audit JSONL events and OpenTelemetry attributes.
+- [ ] Includes manifest-driven samples with high-risk detection >= 90%.
+- [ ] Covers secret-read, dangerous-delete, and non-whitelist-network samples with no allow decisions.
+- [ ] Keeps 500-line script scanning under 1 second in the safety test suite.
+- [ ] Documents that static scanning is not a sandbox.
+- [ ] Preserves default behavior for existing Tool and CodeExecutor paths.
+
+## Code Path Mapping
+
+- Scanner, rules, policy, reports: `trpc_agent_sdk/tools/safety/`
+- CLI: `scripts/tool_safety_check.py`
+- Manifest report generation: `scripts/tool_safety_manifest_report.py`
+- Samples and policy: `examples/tool_safety/`
+- Safety tests: `tests/tools/safety/`
+
+## Validation
+
+```bash
+python -m pytest tests/tools/safety -q
+python scripts/tool_safety_manifest_report.py --strict-policy
+python scripts/tool_safety_check.py \
+  examples/tool_safety/samples/safe_bash.sh \
+  --language bash \
+  --policy examples/tool_safety/policy.yaml
+python scripts/tool_safety_check.py \
+  examples/tool_safety/samples/bash_pipe_exfiltration.sh \
+  --language bash \
+  --policy examples/tool_safety/policy.yaml
+```
+
+## Sample Matrix
+
+- Sample count: 52
+- Decision matches: 52/52
+- Required rule matches: 52/52
+- Categories include safe, secret-read, dangerous-delete, non-whitelist-network,
+  secret-exfiltration, dynamic-code, resource-exhaustion, and process execution.
+
+## Compatibility
+
+- `BashTool` safety guard remains disabled by default.
+- `UnsafeLocalCodeExecutor` safety guard remains disabled by default.
+- `needs_human_review` is not blocked unless `block_on_review=True`.
+
+## Known Limitations
+
+This is a deterministic static pre-execution guard, not a sandbox. It cannot
+guarantee safety against obfuscation, generated code, external binary behavior,
+runtime-only data flow, or interpreter/runtime bugs. Production deployments
+still need filesystem isolation, network egress control, resource limits, and
+runtime audit monitoring.

+```
+
+`examples/tool_safety/all_reports.json` is generated by:
+
+```bash
+python scripts/tool_safety_manifest_report.py --strict-policy
+```
+
+It is a deterministic normalized artifact: report `scan_id` and telemetry
+scan id are pinned to `manifest:<file>`, `timestamp` is pinned to
+`1970-01-01T00:00:00+00:00`, and elapsed duration fields are pinned to `0.0`
+before writing the committed JSON.
+
+## Default Compatibility
+
+- `BashTool` does not enable the safety guard by default.
+- `UnsafeLocalCodeExecutor` does not enable the safety guard by default.
+- Filter, Wrapper, Skill-like callable, and MCP-like callable payload paths are opt-in.
+- `needs_human_review` is not blocked by default unless `block_on_review=true`.
+
+## Known Limitations
+
+This is a deterministic static pre-execution guard, not a sandbox.
+
+It does not replace process sandboxing, least-privilege filesystem permissions,
+network egress controls, resource limits, or runtime audit and monitoring.
+
+Obfuscation, generated code, dynamic imports, external binary behavior, and
+environment-dependent behavior are handled conservatively where possible and may
+require human review.

+# Tool Script Safety Guard
+
+The tool safety guard is an opt-in static pre-execution scanner for Python and
+Bash-like tool scripts. It catches common high-risk patterns before local tool
+execution, returns structured reports, writes sanitized audit events, and can
+attach OpenTelemetry span attributes.
+
+## Threat Model
+
+The guard targets accidental or model-generated tool scripts that read secrets,
+delete sensitive paths, exfiltrate files, install dependencies, invoke privilege
+escalation, run dynamic code, or use shell constructs that need review.
+
+Static scanning is not a sandbox. It cannot guarantee runtime safety against
+obfuscation, encoded payloads, dynamic imports, generated code,
+environment-dependent behavior, external binaries, or interpreter/runtime bugs.
+Production systems still need sandboxing, least privilege, network egress
+control, resource limits, and audit logging.
+
+## Supported Languages
+
+Python scanning uses AST parsing with lightweight alias and constant propagation
+plus targeted text-pattern fallback.
+
+Bash scanning uses shell tokenization, raw-line operator checks, and
+cross-command flow checks for sensitive reads piped into network clients.
+
+Argv-style inputs are scanned with the script or command. Interpreter forms such
+as `python -c ...`, `bash -c ...`, and `bash -lc ...` are scanned using the
+language of the inline code.
+
+## Risk Types
+
+Common risk types include `secret_read`, `secret_output`, `secret_exfiltration`,
+`dangerous_delete`, `network_access`, `process_execution`,
+`dependency_install`, `privilege_escalation`, `dynamic_code`, `shell_features`,
+and `resource_exhaustion`.
+
+## Policy Fields
+
+The YAML policy supports:
+
+- `allowed_domains`
+- `allowed_commands`
+- `denied_paths`
+- `max_timeout_seconds`
+- `max_output_bytes`
+- `long_sleep_seconds`
+- `deny_dependency_install`
+- `deny_privilege_escalation`
+- `review_process_execution`
+- `review_unknown_network`
+- `review_dynamic_code`
+- `review_shell_features`
+- `block_on_review`
+
+Wildcard domains such as `*.trusted.internal` match subdomains. Denied paths
+support user expansion, glob-style filenames, and sensitive basenames such as
+`.env`, `*.pem`, and `id_rsa`.
+
+## Policy Files
+
+`tool_safety_policy.yaml` is the canonical example policy used by the manifest
+report. `policy.yaml` is kept as a compatibility alias for shorter CLI examples
+and contains the same settings.
+
+## CLI Usage
+
+```bash
+python scripts/tool_safety_check.py \
+  --file examples/tool_safety/samples/bash_pipe_exfiltration.sh \
+  --language bash \
+  --policy examples/tool_safety/tool_safety_policy.yaml \
+  --output /tmp/tool_safety_report.json \
+  --audit-log /tmp/tool_safety_audit.jsonl
+```
+
+Exit codes are `0` for allow, `2` for needs human review, `3` for deny, and `1` for CLI errors.
+
+The CLI also accepts a positional file path:
+
+```bash
+python scripts/tool_safety_check.py \
+  examples/tool_safety/samples/safe_bash.sh \
+  --language bash \
+  --policy examples/tool_safety/tool_safety_policy.yaml
+```
+
+Use strict policy mode when validating reviewed policy files:
+
+```bash
+python scripts/tool_safety_check.py \
+  examples/tool_safety/samples/safe_bash.sh \
+  --language bash \
+  --policy examples/tool_safety/tool_safety_policy.yaml \
+  --strict-policy
+```
+
+## Filter Usage
+
+```python
+from trpc_agent_sdk.tools.safety import ToolSafetyFilter
+
+tool_filter = ToolSafetyFilter(
+    policy_path="examples/tool_safety/tool_safety_policy.yaml",
+    audit_log_path="/tmp/tool_safety_audit.jsonl",
+    block_on_review=True,
+)
+```
+
+The filter scans request fields such as `script`, `code`, `command`, `cmd`,
+`python_code`, `bash_code`, and `code_blocks`.
+
+It also scans argv-style fields:
+
+- `command_args`
+- `args`
+- `argv`
+- nested dict-like tool inputs containing those fields
+
+A safety block returns `SAFETY_GUARD_BLOCKED` with a `safety_report` and does
+not set a filter error.
+
+## Wrapper Usage
+
+```python
+from trpc_agent_sdk.tools.safety import with_tool_safety
+
+@with_tool_safety(language="bash", block_on_review=True)
+def run_command(command: str):
+    ...
+```
+
+The wrapper supports sync and async callables.
+
+Tool and Skill-like payloads can opt in through the same Filter/Wrapper path.
+MCP-like payloads can be protected through the generic Filter/Wrapper examples.
+See `skill_wrapper_example.py` for an async Skill-like handler that scans
+`python_code`, argv-style `command_args`, nested dict-like payloads, and
+MCP-like `params.arguments` input before calling the wrapped function.
+
+## BashTool Opt-In Usage
+
+```python
+from trpc_agent_sdk.tools import BashTool
+
+bash = BashTool(
+    enable_safety_guard=True,
+    safety_policy_path="examples/tool_safety/tool_safety_policy.yaml",
+    safety_audit_log_path="/tmp/tool_safety_audit.jsonl",
+    safety_block_on_review=True,
+)
+```
+
+The default remains disabled to preserve existing behavior.
+
+## UnsafeLocalCodeExecutor Opt-In Usage
+
+```python
+from trpc_agent_sdk.code_executors.local import UnsafeLocalCodeExecutor
+
+executor = UnsafeLocalCodeExecutor(
+    enable_safety_guard=True,
+    safety_policy_path="examples/tool_safety/tool_safety_policy.yaml",
+    safety_audit_log_path="/tmp/tool_safety_audit.jsonl",
+    safety_block_on_review=True,
+)
+```
+
+The default remains disabled to preserve existing behavior.
+
+## Report Schema
+
+Reports include `scan_id`, `timestamp`, `decision`, `risk_level`, `findings`,
+`tool_name`, `language`, `elapsed_ms`, `sanitized`, `blocked`, `summary`, and
+`telemetry_attributes`.
+
+Each finding includes `rule_id`, `risk_type`, `risk_level`, `decision`,
+`evidence`, `recommendation`, `message`, `line`, `column`, and `metadata`.
+
+## Sample Manifest
+
+`samples/manifest.yaml` is the source of truth for the sample validation matrix. Each entry contains:
+
+- `file`
+- `language`
+- `expected_decision`
+- `required_rule_id`
+- `category`
+- `high_risk`
+
+Tests read this manifest directly. Adding a new sample requires one manifest
+entry with the expected scanner outcome and at least one rule that must appear
+unless the sample is expected to allow.
+
+Run manifest validation with:
+
+```bash
+python -m pytest tests/tools/safety/test_manifest_validation.py -q
+```
+
+## All Reports
+
+`all_reports.json` is generated by statically scanning every manifest sample
+with `tool_safety_policy.yaml`. It stores:
+
+- expected decision
+- actual decision
+- required-rule match
+- category
+- high-risk flag
+- full sanitized report
+
+The manifest report normalizes dynamic fields so rerunning the generator
+produces a stable review artifact: report `scan_id` and telemetry scan id are
+`manifest:<file>`, `timestamp` is `1970-01-01T00:00:00+00:00`, and elapsed
+duration fields are `0.0`.
+
+Regenerate it with:
+
+```bash
+python scripts/tool_safety_manifest_report.py --strict-policy
+```
+
+This command is CI-friendly: it exits with status `1` if any sample decision
+differs from the manifest, any required rule is missing, or strict policy
+validation fails. Failure output includes the sample file, expected decision,
+actual decision, required rule, and actual rule IDs.
+
+The current corpus contains 52 samples with 52/52 decision matches and 52/52
+required-rule matches.
+
+## Audit Schema
+
+Audit JSONL writes one event per scan with `scan_id`, `timestamp`, `tool_name`,
+`decision`, `risk_level`, `rule_ids`, `elapsed_ms`, `sanitized`, `blocked`, and
+`trace_attributes`. Evidence and raw scripts are not written to audit events.
+
+## Telemetry Attributes
+
+When OpenTelemetry is installed and a span is recording, the guard sets:
+
+- `tool.safety.scan_id`
+- `tool.safety.decision`
+- `tool.safety.risk_level`
+- `tool.safety.rule_id`
+- `tool.safety.blocked`
+- `tool.safety.sanitized`
+- `tool.safety.tool_name`
+- `tool.safety.duration_ms`
+
+## Extension Guide
+
+Add new rule checks in `trpc_agent_sdk.tools.safety._rules`, return
+`RiskFinding` with sanitized evidence, and cover the behavior with Python/Bash
+scanner tests. Keep rules deterministic and avoid executing target scripts.
+
+For local, in-process customization, register a small callable rule:
+
+```python
+from trpc_agent_sdk.tools.safety import Decision
+from trpc_agent_sdk.tools.safety import RiskFinding
+from trpc_agent_sdk.tools.safety import RiskLevel
+from trpc_agent_sdk.tools.safety import register_safety_rule
+
+
+def block_marker(context):
+    if "CUSTOM_MARKER" not in context.script:
+        return []
+    return [
+        RiskFinding(
+            rule_id="CUSTOM_MARKER_BLOCK",
+            risk_type="custom",
+            risk_level=RiskLevel.HIGH,
+            decision=Decision.DENY,
+            evidence="CUSTOM_MARKER",
+            recommendation="Remove the custom marker before execution.",
+            message="Custom marker detected.",
+        )
+    ]
+
+
+register_safety_rule("marker", block_marker, languages=["python", "bash"])
+```
+
+Custom rules are called after built-in rules. If a custom rule raises, the
+scanner emits a `needs_human_review` finding instead of allowing execution.
+The API intentionally does not load rules through dynamic imports.
+
+## Validation Matrix
+
+The sample matrix covers:
+
+- safe Python and Bash scripts
+- dangerous and dynamic deletion
+- secret reads, credential files, and sensitive taint propagation
+- whitelisted and non-whitelisted network calls
+- `requests.Session`, `httpx.Client`, `aiohttp.ClientSession`,
+  `urllib.request`, and sockets
+- command-line argument scanning for argv and interpreter forms
+- bypass regression samples for `Path.home()`, `subprocess` interpreter forms,
+  shell `bash -c` / `sh -c`, `find -delete`, `xargs rm -rf`, and curl data-file
+  exfiltration
+- subprocess review and shell injection review
+- dependency install denial and eval review
+- infinite loops, long waits, large allocation review, unbounded output review,
+  and large zero-fill write review
+- sensitive output denial and pipe exfiltration denial
+- Bash network egress through `curl`, `wget`, `nc`, `netcat`, `socat`, `ssh`,
+  `scp`, `rsync`, `openssl s_client`, and `/dev/tcp`
+- dynamic URL review, shell features, and background processes
+
+## Limitations
+
+Static scanning favors fast deterministic checks over completeness. It can miss
+obfuscated payloads, encoded commands, generated code, external binary behavior,
+and runtime-dependent flows.
+
+Treat it as a pre-execution guardrail, not isolation. It does not replace:
+
+- process sandboxing
+- least-privilege filesystem permissions
+- network egress controls
+- resource limits
+- runtime audit and monitoring
