2-repro-issue — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited 2-repro-issue (Agent Skill) and scored it 45/100 (orange). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.
*.sig, SIGNATURES) outside the documentation.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.

gh issue view $NUM --repo $REPO --commentsFrom the thread extract the tool, arguments, observed result, runtime, LinkedIn variant, and related issues. Distinguish observations, source findings, hypotheses, and work not run.
Map the tool to code:
linkedin_mcp_server/tools/<surface>.py. MCP entrypoint and arg validationdocs/linkedin-architecture.md. Generated ownership table; follow it to linkedin_mcp_server/linkedin/<owner>.py rather than treating linkedin/extractor.py as the implementationlinkedin_mcp_server/linkedin/fields.py. PERSON_SECTIONS / COMPANY_SECTIONS (each entry = one navigation)tests/linkedin/test_<owner>.py; use tests/test_fields.py, tests/test_identifiers.py, and tests/test_link_metadata.py for those owners, and tests/linkedin/test_facade_*.py only for facade contractsInspect the relevant source at the current SHA. Do not invent a LinkedIn result or an unimplemented tool call.
This step is complete when the report names the issue, the code SHA, the inspected evidence, the facts established, the unverified runtime claims, and the next decision.
Use one of:
A successful call on the maintainer's different account never refutes a failure on the reporter's account. Target content language is not the authenticated account's UI language. Captures and URL or attribute evidence may establish the needed variation without another live call.
Review reporter commands before execution. Publishing permission does not authorize send_message, a connection request, a forced login, or repeated calls with account side effects. Record sent, recipient_selected, and retry_safe as observed fields, not as replay authorization.
If the next decision needs a live observation, name the exact unresolved question and ask before login, session changes, or LinkedIn writes. If the human declines, keep the packet-and-source verdict.
Only after an explicit yes for this run. Use uv run, never uvx, so the server reflects the workspace. Record the actual tool, arguments, runtime, account variant, code SHA, and timestamp before the call. Keep the reporter's installed-launcher context distinct from a workspace check.
