provider-claude — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited provider-claude (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Process guidance for keeping the gateway's Claude (claude) integration aligned with the upstream CLI. This skill does not define argv/env behaviour — the single mechanical source of truth is UPSTREAM_CLI_CONTRACTS.claude in src/upstream-contracts.ts, enforced by validateUpstreamCliArgs / validateUpstreamCliEnv. Never re-encode flags, output modes, permission modes, or session rules here or in TOML.
| Field | Value |

| CliType | claude |
| Executable | claude |
| Package | @anthropic-ai/claude-code (npm) |

These values mirror UPSTREAM_CLI_CONTRACTS.claude.upstreamMetadata and docs/upstream/provider-sources.dag.toml ([providers.claude]). The TypeScript metadata is authoritative; the TOML is scanner input only.
claude request fails the upstream contract check before spawn.npm run upstream:scan -- --live reports a change on the Claude changelog.controls:
provider_tool_capabilities({cli:"claude"})For a cached read-only resource, use provider-tools://claude.
claude_request for normal turns and claude_request_async forlong-running review, implementation, or analysis. Sync calls may auto-defer; poll llm_job_status and fetch with llm_job_result when that happens.
model unless the caller explicitly asked for a specific variant; thegateway resolves the configured Claude default.
allowedTools, disallowedTools, and tools, but do not pass an empty allowlist for reviews.
mcpServers only for gateway-known MCP servers, and setstrictMcpConfig:true when missing MCP access should fail fast.
approvalStrategy:"mcp_managed" over rawdangerouslySkipPermissions; the gateway approval gate runs before Claude's permissive execution mode is applied.
createNewSession, sessionId, or continueSession for real Claudecontinuity. Claude also supports structured output via outputFormat and jsonSchema.
# Offline summary (no network):

npm run upstream:scan -- --live --provider claude --fail-on-critical
# Persist a content-hash snapshot + dated report:
npm run upstream:scan -- --live --provider claude --write-snapshot --write-reportA failed fetch is advisory (exit 0) unless --fail-on-critical is passed; it never breaks the default release gate.
