Add security-remediation skill and restructure security-review report format

[Atharva0506]

Addressed Issues:

No related issue — this adds tooling under .claude/skills/, agreed on separately with a maintainer.

Screenshots/Recordings:

Not applicable — this change only adds/updates Claude Code skill definitions, no application behavior changes.

Additional Notes:

Updates the security-review skill and adds a new companion security-remediation skill:

• security-review now separates deliberate design tradeoffs into a Notes section instead of misfiling them as Findings or Limitations, and saves its report to unremediated-security-reviews/ (gitignored) instead of only printing it to chat.
• security-remediation (new) reads that report, matches remediating commits via git log, confirms with the user, and — once every finding is remediated or explained — publishes both files to a tracked security-reviews/ folder.

Summary by CodeRabbit

• New Features
  • Added guided security reviews that assess applicable project areas, prioritize findings by severity and confidence, and produce structured reports with review details and limitations.
  • Added a remediation workflow that helps verify findings against subsequent changes, record explanations for unresolved issues, and publish completed reports once every finding is addressed or explained.

Walkthrough

Adds security review and remediation skill procedures. The review skill creates structured reports. The remediation skill checks commits, requests confirmation, and publishes reports only after all findings are resolved. The change also ignores the unremediated-report directory and updates a checklist timestamp.

Changes

Security Review and Remediation Workflow

Merge Risk: 🔵 Low · up to 8a8f5

Most runs using the standard unremediated-report location are unaffected, but closeout can fail for a report already in the destination, and rapid repeated reviews can collide. These are bounded issues to address or accept before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 8a8f5

The new workflow has useful confirmation and publication gates, but it can accept a report from outside the usual report directory and does not specify how to recover if publishing the two files stops partway through. No exploitable command injection has been established.

Retained concerns

• Low · security · inferred: An explicitly named report need not be under the ignored review directory, yet the workflow can read it, save a companion file beside it, and move it into the trackable review directory. The instructions do not establish path containment or how move arguments are handled.
• Low · reliability · inferred: Publishing the original and companion report requires separate moves. A failed, interrupted, repeated, or concurrent closeout can leave the pair in different states; the specified post-move check does not define rollback or recovery.

Security review details

Security Blast Radius

• inferred — The direct scope is files reachable with the coding agent's local read and move authority, plus reports placed where Git can track them. The supplied evidence does not establish a remote push or a broader service dependency.

Security Findings and Attack Paths

• inferred — The deferred injection candidate identifies the move operation as a sensitive sink, but the report path is selected before parsing report contents. The available instructions do not prove that attacker-controlled report text reaches a command argument or that a path escapes execution-layer controls.

Trust Boundaries and Controls

• observed — The skill treats report text as untrusted for Git queries, requires a full hexadecimal review commit and quoted report-derived Git arguments, and requires user confirmation or explanation before publication. Its explicitly named source path has no corresponding containment rule in the skill.

Resilience and Maintainability Implications

• inferred — The all-findings gate protects against intentional early publication, but sequential file moves leave pair integrity dependent on successful completion and recovery not specified here.

Hardening Proposals

• proposed — Define canonical source-path containment and safe command argument handling, and specify preflight destination checks plus a recoverable, repeatable two-file publication procedure.

Inline comments:
In @.claude/skills/security-remediation/SKILL.md:
- Around line 143-151: Update the report publication flow in Step 6 to use the
report path selected in Step 1, rather than assuming the source is in
unremediated-security-reviews/. Preserve the selected path throughout the
workflow; alternatively, validate and reject paths outside the expected
directory before processing them.
- Line 8: Update the allowed-tools frontmatter in the security-remediation skill
to include the AskUserQuestion tool used by Step 4, or revise Step 4 to use a
host-supported interaction; keep the change limited to enabling its required
user-confirmation flow.
- Around line 88-92: Update the commit-link normalization and publication
guidance to remove URL userinfo before constructing links; publish only when a
safe HTTPS base URL can be produced, and otherwise refuse publication.
- Around line 55-60: Update the Git command guidance in steps 2–3 to validate
the report-derived <review-commit> as a full commit ID and pass both
<review-commit> and <file> as safely delimited arguments, preventing report text
from changing command parsing. Keep the existing commit-range and file-filter
behavior.
- Around line 58-62: Update step 3 in the security-remediation instructions to
use the full post-review commit list as the candidate pool. Keep commits
touching the finding’s file as the initial priority, but inspect commits
affecting other files when their paths or diffs may address the finding; retain
the existing guidance for judging candidates.

In @.claude/skills/security-review/SKILL.md:
- Around line 312-316: Update the Network communication checklist in the
security review skill so missing certificate pinning alone is not reported as a
vulnerability; require a concrete trust-bypass condition or classify pinning as
defense-in-depth. Keep the existing checks for sensitive HTTP requests and
disabled certificate validation.
- Line 522: Add a Markdown or text language identifier to each untagged
report-format fence: the report outline at
.claude/skills/security-review/SKILL.md lines 522–522, findings template at
.claude/skills/security-review/SKILL.md lines 558–558, findings example at
.claude/skills/security-review/SKILL.md lines 571–571, notes template at
.claude/skills/security-review/SKILL.md lines 597–597, and remediation template
at .claude/skills/security-remediation/SKILL.md lines 96–96.
- Around line 661-663: Update the report filename generation in the
security-review report flow to prevent same-second reviews from overwriting each
other: include the reviewed revision in the filename or use an exclusive-create
check, while preserving the report directory and timestamp.
- Around line 69-70: Update the review-scope instructions around `git diff` to
resolve and use an explicit base and reviewed revision, so committed PR changes
are included and the revision matches the review. Record a snapshot identifier
that remediation can use instead of relying on `git diff` without a base or `git
rev-parse HEAD`.
- Around line 672-674: Update the user-facing instruction in the security-review
skill to describe the saved folder as untracked and excluded from Git, not
private. Clarify that Git exclusion does not provide filesystem privacy and that
confidentiality requires appropriate filesystem access controls; preserve the
existing remediation-skill guidance.
- Around line 662-668: Resolve the repository root with `git rev-parse
--show-toplevel` before using workflow paths, and anchor both the report
directory and `.gitignore` operations to that absolute path. Apply this change
in `.claude/skills/security-review/SKILL.md` at lines 662-668 and
`.claude/skills/security-remediation/SKILL.md` at lines 31-39.

can we make this less claude-specific by putting these files in a folder different from .claude/ where both Claude and other agents could find and use them?

[Zahnentferner]

I am 100% familiarized with the most current conventions related to this.
