The engine is a heavy third-party package and is **not bundled**: the first `--deep` run offers to install it interactively (isolated, version-pinned `uv tool install`, pip `--user` fallback), or set it up ahead of time with `rafter agent update-skill-scanner` / `rafter agent init --with-skill-scanner`, and remove it with `rafter agent remove-skill-scanner`. Node + Python parity (both shell out to the same external CLI and parse identical JSON, mirroring the betterleaks pattern). `rafter agent audit-skill --deep` remains as a deprecated back-compat alias. Security-reviewed: list-form subprocess (no shell), version-pinned installer, untrusted skill paths passed as single argv elements. + +### Fixed +- **Hardened `RAFTER_API_KEY` handling** (sable-q9to). Three credential gaps closed across Node + Python: (1) `~/.rafter/config.json` is now written `0600` (dir `0700`) and an existing looser-perm file is tightened on the next write; (2) `config show`/`get`/`set`, the MCP `get_config` tool, and the `rafter://config` / `rafter://policy` resources now **redact** values under credential-named keys (`api_?key|token|secret|password|credential` → `abcd****`) at every render path — the stored config is never mutated; (3) a key persisted via `rafter agent config set backend.apiKey` is now read as the lowest-precedence source (`--api-key` flag > `RAFTER_API_KEY` env > global config). Trust boundary verified: the config fallback is read only from the **global** config (`get` → `load`, never `loadWithPolicy`), so a hostile project-local `.rafter.yml` cannot inject a key that redirects scans to another account. `rafter-secure-design` run before coding. + ### Changed - **Pinned the `.rafter.yml` `ignore` matching contract in `CLI_SPEC.md`** (sable-eltr). The glob semantics are now specified exactly — `*` stays within a path segment, `**` crosses segments, bare patterns match the basename, relative globs auto-anchor anywhere — replacing the vague (and slightly inaccurate) "minimatch (Node) / fnmatch (Python)" wording. `rules` selectors now documented as matching a finding's **rule name or rule id** (case-insensitively). These semantics are honored identically by the local CLI engines and the remote `rafter run` backend, which adopted the CLI's matcher (rafter-backend ra-a8j, in response to rafter-cli#166) — so a suppression that works locally now works remotely. `suppress_finding` tool descriptions updated to match. diff --git a/README.md b/README.md index f207b3ad..b47073d0 100644 --- a/README.md +++ b/README.md @@ -306,6 +306,8 @@ rafter skill review --installed --summary # terse table across all agents **Deep analysis** (via OpenClaw, if installed): 12-dimension security review covering trust/attribution, network security, command execution, file system access, credential handling, input validation, data exfiltration, obfuscation, scope alignment, error handling, dependencies, and environment manipulation.

Optionally add an installer hook + (`rafter agent update-skill-scanner` / a `--with-skill-scanner` init flag) + that runs `uv pip install cisco-ai-skill-scanner` into a managed location, + analogous to `rafter agent update-betterleaks` / the BinaryManager. This PoC + implements option 3 (detect + hint); the installer hook is the GA follow-up. + +**Recommendation: option 3.** Keeps Rafter's zero-dependency / offline default +intact, preserves Node↔Python parity, and isolates skill-scanner's heavy tree +behind an explicit opt-in. + +--- + +## (f) Surprises / GA blockers + +- **skill-scanner only scans directories, never single files.** Our + `audit-skill` takes a file path.

We rely on the parsed JSON for + truth and use `--fail-on-severity medium` only as corroboration. Worth a note + in CLI_SPEC so nobody trusts the bare exit code. +- **Heavy dependency tree + import-time noise.** litellm prints Bedrock/ + SageMaker pre-load warnings to stderr on every invocation (botocore absent). + Harmless for us (we don't use those paths) and we read stdout only, but it's + ugly; consider suppressing skill-scanner stderr in the wrapper for clean UX. +- **`policy_violation`/INFO findings (e.g. missing license) are noise** for a + security audit. Mapped to `low` and excluded from the exit-code floor so they + don't cause false "fail" signals. GA: consider filtering INFO out of default + output entirely, surfacing only with a `--verbose`/`--all-findings` flag. +- **Version drift risk.** The JSON shape is stable in 2.0.11 but undocumented as + a contract. GA: pin/record a known-good version and parse defensively (we + already `.get()` every field). An installer hook would let us pin like + `BETTERLEAKS_VERSION`. +- **Not a GA blocker but a decision:** whether to also expose `--use-behavioral` + (offline AST dataflow) as a deeper still-offline tier.
