Add security-review and security-remediation skills

[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 Claude Code skill definitions, no application behavior changes.

Additional Notes:

Adds two Claude Code skills, ported from the same change in ThruBox-Server:

• security-review guides a security-focused code review, 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 identify and document vulnerabilities, assign severity, and produce structured reports.
  • Added a remediation workflow for confirming fixes or documenting unresolved findings. Reports remain unpublished until every finding is resolved or explained and publication is approved.
  • Security review and remediation reports are drafted in an excluded directory; completed reports can be published to the security reviews directory.
• Chores
  • Updated checklist status information.

Walkthrough

Adds instructions for security reviews and remediation reporting. It also ignores the directory for unremediated security reviews and updates the checklist status date.

Changes

Security review and remediation

Layer / File(s)	Summary
Security review workflow skills/security-review/SKILL.md, .gitignore	Adds instructions for selecting review scope, applying security checklists, filtering and rating findings, and saving reports. Adds an ignore rule for unremediated-security-reviews/.
Confirm and report remediations skills/security-remediation/SKILL.md	Adds instructions for finding review reports, checking candidate commits, confirming remediations with the user, and saving or publishing remediation reports.

Checklist timestamp

Layer / File(s)	Summary
Update checklist status date checklist-status.json	Changes the updated date to 2026-09-23.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Suggested labels: Bash Lang

Merge Risk: 🟡 Moderate · up to beba4

Existing security reports can be overwritten during creation or publication. Add collision safeguards before merging; application behavior is unchanged.

Security Architecture Review

Security architecture risk: 🔵 Low · up to beba4

The changes are limited to repository security-review workflows. Publication requires confirmed fixes or explicit explanations, but safe handling of selected Git references remains uncertain, and interrupted publication has no defined recovery procedure.

Retained concerns

• Low · security · inferred: The new diff-review workflow does not specify the selected base ref's trust source or safe passage into shell commands. Command safety consequently depends on unavailable execution controls. This is an unresolved authority-boundary concern, not verified command injection.

Security review details

Security Blast Radius

• inferred — The intended mutable scope is repository report storage, the ignore rule, and relocation of the selected report pair. If the deferred ref-to-shell path proved exploitable, its maximum exposure would depend on the executor's filesystem and credential privileges, which are unknown; repository-local instructions do not establish sandbox containment.

Security Findings and Attack Paths

• inferred — No verified injection path is established. The deferred candidate concerns a selected base ref entering the git diff command template, but attacker control over that ref and unsafe shell construction remain unproven. The reviewed operation restrictions are counterevidence, not proof that the missing execution boundary is safe.

Trust Boundaries and Controls

• observed — Remediation explicitly treats report text as untrusted command input, validates the reviewed commit hash, quotes arguments, and requires user confirmation for each resolution. Published commit links must omit embedded credentials, with bare hashes used when a safe HTTPS URL cannot be produced.

Resilience and Maintainability Implications

• inferred — Report creation and paired publication have no specified locking, collision handling, transaction, or recovery protocol. Interrupted moves could leave the source report publication-eligible without its accompanying closeout report. Because publication follows the all-findings gate, this is a closeout-integrity and recovery limitation, not demonstrated publication of unaccepted findings.

Hardening Proposals

• proposed — Define trusted base-ref selection and argument-safe resolution before invoking Git, and document the execution permission and sandbox assumptions. This would make the currently deferred command boundary assessable.
• proposed — Make report creation collision-safe and define resumable paired publication with destination checks and recovery for interrupted moves. Preserve the existing user-confirmation gate during retries.

Then hops through commits, stage by stage.
It asks which fixes are confirmed,
And notes where open issues turn.
Two reports rest, kept out of sight.}

Review comments at @skills/security-remediation/SKILL.md:
- Around line 171-172: Update the report publication flow around the git status
and git mv/plain mv selection to check both destination paths before writing or
moving either report; if either destination already exists, stop publication and
ask the user to resolve the collision rather than overwriting it.

Review comments at @skills/security-review/SKILL.md:
- Around line 671-674: Update the report-writing flow for the sec_review
timestamp-and-commit filename to avoid collisions when reviews share both
values: create the output path exclusively, and if it already exists, append a
unique per-run suffix and retry without overwriting an existing report.
