deps

/deps — Dependency Health & Decision Tracker

Scans project dependencies for outdated versions and CVEs, classifies severity, and records human decisions (update / defer / skip) in Atrium so the reasoning survives across sessions.

Data flow: /deps scan both reads AND writes to Atrium:

• Reads: existing decisions to mark assessed deps
• Writes: fresh outdated findings via POST /api/dev-projects/sync (keeps Atrium current between scheduled audit runs)

Graceful degradation: When Atrium is unreachable, scan/classify still works locally. Decision storage and decision-coverage checks are silently skipped with a note.

Quick Start

/deps                        # summary: outdated deps + decision status for current project
/deps scan                   # full scan → PASS/WARN/FAIL gate (used by /health deps)
/deps decide                 # interactive: assess each unassessed finding, record to Atrium
/deps status                 # fetch current snapshot from Atrium (deps + active decisions)
/deps history                # fetch version changelog from Atrium (newest first)

Invoked by: /health deps as part of the full project health audit.

Atrium URL Resolution

All subcommands that talk to Atrium resolve the base URL in this order:

---

Subcommand: /deps (summary)

Show dependency status for the current project — outdated count by severity, decision coverage.

Steps:

1. Detect project slug from current directory (last segment of pwd).
2. If Atrium unreachable: fall through to local scan mode (show outdated only, no decisions).
3. If Atrium available: show dep table with decision column.

Output:

## Dependency Status — <project> — <date>

  next                 14.2.0 → 15.0.0   [HIGH]     DEFERRED until 2026-04-27
  fastapi              0.109.0 → 0.115.0  [MEDIUM]   unassessed
  httpx                0.27.0 → 0.28.0    [LOW]      unassessed

Summary: 1 CRITICAL · 0 HIGH unassessed · 2 MEDIUM unassessed
Run `/deps decide` to record decisions. Run `/deps scan` for full gate.

---

Subcommand: /deps scan

Full dependency scan producing a Deps [PASS|WARN|FAIL] gate. Used by /health deps.

Step 1 — Detect ecosystems

Scan the current directory for manifest files:

HAS_PYTHON=false; HAS_NODE=false; HAS_RUST=false; HAS_GO=false
[ -f pyproject.toml ] || [ -f requirements.txt ] || [ -f setup.py ] && HAS_PYTHON=true
[ -f package.json ] && HAS_NODE=true
[ -f Cargo.toml ] && HAS_RUST=true
[ -f go.mod ] && HAS_GO=true

If no manifests found: output Deps [SKIP] — no manifest files found, stop.

Step 2 — Collect outdated packages

Run package manager outdated commands. Parse into a unified list of findings.

Each finding has: package, ecosystem, current_version, available_version

Python:

# uv preferred; fallback to pip
if command -v uv &>/dev/null; then
  uv pip list --outdated --format json 2>/dev/null
else
  pip list --outdated --format json 2>/dev/null
fi

Parse: jq '.[] | {package: .name, ecosystem: "python", current_version: .version, available_version: .latest_version}'

Node.js:

npm outdated --json 2>/dev/null || true
# npm outdated exits non-zero when outdated deps exist — `|| true` prevents abort

Parse: jq 'to_entries[] | {package: .key, ecosystem: "npm", current_version: .value.current, available_version: .value.latest}'

Rust (if cargo-outdated installed):

if command -v cargo-outdated &>/dev/null; then
  cargo outdated --format json 2>/dev/null
fi

Parse the dependencies array. If cargo-outdated not installed: note "install cargo-outdated for Rust dep checking" and skip.

Go:

if [ "$HAS_GO" = "true" ]; then
  go list -m -u -json all 2>/dev/null | jq -s '.[] | select(.Update != null) |
    {package: .Path, ecosystem: "go", current_version: .Version, available_version: .Update.Version}'
fi

Step 3 — Run security audits

Python:

pip audit --format json 2>/dev/null

Parse: extract packages with vulns list non-empty. Each vuln has id (CVE/GHSA), fix_versions.

Node.js:

npm audit --json 2>/dev/null || true

Parse: jq '.vulnerabilities | to_entries[] | {package: .key, severity: .value.severity, cves: [.value.via[] | select(type=="object") | .cve // .url]}'

Rust (if cargo-audit installed):

if command -v cargo-audit &>/dev/null; then
  cargo audit --json 2>/dev/null
fi

Step 4 — Classify severity

For each finding, assign severity:

Severity	Condition
critical	Has CVE IDs OR package is EOL (detected by pip-audit fix_versions empty)
high	Major version bump: available_version major > current_version major (semver X changed)
medium	Minor version bump: major same, minor changed
low	Patch only: major.minor same, patch changed

Semver parsing (bash):

major() { echo "$1" | cut -d. -f1 | tr -dc '0-9'; }
minor() { echo "$1" | cut -d. -f2 | tr -dc '0-9'; }

Security audit findings always override to critical regardless of version bump type.

Merge: if a package appears in both outdated and audit lists, take the higher severity and union the CVE IDs.

Step 5 — Fetch decisions from Atrium

SLUG=$(basename "$(pwd)")

DECISIONS=$(curl -sf --max-time 5 \

If DECISIONS is empty: mark all findings as unassessed, skip coverage check.

For each finding:

• If an active decision exists for (package, ecosystem): mark as assessed, show decision + review_at.
• Check GET /{slug}/dep-decisions/overdue — any overdue decisions escalate to critical.

Step 6 — Push fresh findings to Atrium

Construct a POST /api/dev-projects/sync payload from the scan results. This keeps Atrium current between scheduled audit runs.

# Build deps array as JSON
DEPS_JSON=$(jq -n \
  --argjson findings "$FINDINGS_JSON" \
  '$findings | map({
    package: .package,
    ecosystem: .ecosystem,
    current_version: .current_version,
    available_version: .available_version,
    severity: .severity,
    cve_ids: (.cve_ids // []),
    is_dev_dep: false
  })')

SYNC_PAYLOAD=$(jq -n \
  --arg name "$SLUG" \
  --arg slug "$SLUG" \
  --arg path "$(pwd)" \
  --argjson deps "$DEPS_JSON" \
  '{projects: [{name: $name, slug: $slug, path: $path, deps: $deps}]}')

  -H "Content-Type: application/json" \
  -d "$SYNC_PAYLOAD" >/dev/null 2>&1 || true

Skip silently if Atrium unreachable.

Step 7 — Gate and output

Gate logic:

Gate	Condition
PASS	0 critical findings AND 0 unassessed high findings AND 0 overdue decisions
WARN	0 critical BUT unassessed high/medium findings exist OR ≥1 decision due within 7 days
FAIL	Any critical (CVE or EOL) OR any overdue deferred decision
SKIP	No manifest files found

Output format (matches /health report style):

### Deps [PASS|WARN|FAIL]

Scanned: python (pyproject.toml), npm (package.json)
Date: YYYY-MM-DD

| Package  | Ecosystem | Current  | Available | Severity | Decision          |
|----------|-----------|----------|-----------|----------|-------------------|
| next     | npm       | 14.2.0   | 15.0.0    | HIGH     | DEFERRED 2026-04-27 |
| fastapi  | python    | 0.109.0  | 0.115.0   | MEDIUM   | unassessed        |
| httpx    | python    | 0.27.0   | 0.28.0    | LOW      | unassessed        |

- ✗ 0 CRITICAL
- ⚠ 1 unassessed HIGH
- ⚠ 2 unassessed MEDIUM
- ✓ 1 DEFERRED (within review date)

Summary line for /health report: Deps [WARN] 0 critical · 1 unassessed HIGH · 2 unassessed MEDIUM

Subcommand: /deps decide

Interactive decision workflow. For each unassessed finding (sorted by severity desc), present options and record the decision in Atrium.

Steps:

1. Run /deps scan to get current findings.
2. Filter to unassessed only.
3. For each finding (CRITICAL first, then HIGH, MEDIUM, LOW):

─────────────────────────────────────────────────
Package:   next  (npm)
Current:   14.2.0  →  Available: 15.0.0
Severity:  HIGH (major version bump)
CVEs:      none
─────────────────────────────────────────────────

Decision:
  [u] update   — will update now (no Atrium record needed)
  [d] defer    — not now, but schedule review
  [s] skip     — permanently skip this version jump

Choice:

4. For update: Record nothing in Atrium (dep will disappear after update+rescan). Print: → Marked for update. Run update commands after this session.

5. For defer:

   • Prompt: Rationale (why not now)?
   • Prompt: Review in how many days? [30]

6. For skip:

   • Prompt: Rationale (why skip this version permanently)?
   • POST with review_at: null

7. After all findings processed, print summary:

Decisions recorded: 2 deferred · 1 to update · 1 skipped
Run `/deps scan` to verify gate status.

Atrium unavailable: If POST fails, print the decision in a copyable format and suggest recording manually later.

---

Subcommand: /deps status

Fetch the current dep snapshot + active decisions from Atrium.

SLUG=$(basename "$(pwd)")
echo ""
echo "Active decisions:"
  jq '.[] | "\(.package) [\(.ecosystem)]: \(.decision) — \(.rationale) (review: \(.review_at // "never"))"'

If project not found in Atrium (404): print "Project '${SLUG}' not yet registered in Atrium. Run /deps scan to register and popula
