Multi-agent collaboration plugin that spawns N parallel subagents competing on the same task via git worktree isolation. Agents work independently, results are evaluated by metric or LLM judge, and the best branch is merged. Use when: user wants multiple approaches tried in parallel — code optimization, content variation, research exploration, or any task that benefits from parallel competition. Requires: a git repo.
Design production-grade multi-agent orchestration systems. Covers five core patterns (sequential pipeline, parallel fan-out/fan-in, hierarchical delegation, event-driven, consensus), platform-specific implementations, handoff protocols, state management, error recovery, context window budgeting, and cost optimization.
App Store Optimization toolkit for researching keywords, optimizing metadata, and tracking mobile app performance on Apple App Store and Google Play Store.

Build a bipartite graph of people and files from git history, then compute ownership risk and export graph artifacts for Neo4j/Gephi. Also build a file co-change graph (Jaccard similarity on shared commits) to cluster files by how they move together while ignoring large, noisy commits.
networkx (required; community detection is enabled by default)Install with:
pip install networkx
--since/--until).scripts/run_ownership_map.py (co-change graph is on by default; use --cochange-max-files to ignore supernode commits).--graphml).scripts/query_ownership.py for bounded JSON slices.references/neo4j-import.md).By default, the co-change graph ignores common “glue” files (lockfiles, .github/*, editor config) so clusters reflect actual code movement instead of shared infra edits. Override with --cochange-exclude or --no-default-cochange-excludes. Dependabot commits are excluded by default; override with --no-default-author-excludes or add patterns via --author-exclude-regex.
If you want to exclude Linux build glue like Kbuild from co-change clustering, pass:
python skills/skills/security-ownership-map/scripts/run_ownership_map.py \
--repo /path/to/linux \
--out ownership-map-out \
--cochange-exclude "**/Kbuild"
Run from the repo root:
python skills/skills/security-ownership-map/scripts/run_ownership_map.py \
--repo . \
--out ownership-map-out \
--since "12 months ago" \
--emit-commits
Defaults: author identity, author date, and merge commits excluded. Use --identity committer, --date-field committer, or --include-merges if needed.
Example (override co-change excludes):
python skills/skills/security-ownership-map/scripts/run_ownership_map.py \
--repo . \
--out ownership-map-out \
--cochange-exclude "**/Cargo.lock" \
--cochange-exclude "**/.github/**" \
--no-default-cochange-excludes
Communities are computed by default. To disable:
python skills/skills/security-ownership-map/scripts/run_ownership_map.py \
--repo . \
--out ownership-map-out \
--no-communities
By default, the script flags common auth/crypto/secret paths. Override by providing a CSV file:
# pattern,tag,weight
**/auth/**,auth,1.0
**/crypto/**,crypto,1.0
**/*.pem,secrets,1.0
Use it with --sensitive-config path/to/sensitive.csv.
ownership-map-out/ contains:
people.csv (nodes: people)files.csv (nodes: files)edges.csv (edges: touches)cochange_edges.csv (file-to-file co-change edges with Jaccard weight; omitted with --no-cochange)summary.json (security ownership findings)commits.jsonl (optional, if --emit-commits)communities.json (computed by default from co-change edges when available; includes maintainers per community; disable with --no-communities)cochange.graph.json (NetworkX node-link JSON with community_id + community_maintainers; falls back to ownership.graph.json if no co-change edges)ownership.graphml / cochange.graphml (optional, if --graphml)people.csv includes timezone detection based on author commit offsets: primary_tz_offset, primary_tz_minutes, and timezone_offsets.
Use scripts/query_ownership.py to return small, JSON-bounded slices without loading the full graph into context.
Examples:
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out people --limit 10
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out files --tag auth --bus-factor-max 1
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out person --person alice@corp --limit 10
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out file --file crypto/tls
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out cochange --file crypto/tls --limit 10
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out summary --section orphaned_sensitive_code
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out community --id 3
Use --community-top-owners 5 (default) to control how many maintainers are stored per community.
Run these to answer common security ownership questions with bounded output:
# Orphaned sensitive code (stale + low bus factor)
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out summary --section orphaned_sensitive_code
# Hidden owners for sensitive tags
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out summary --section hidden_owners
# Sensitive hotspots with low bus factor
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out summary --section bus_factor_hotspots
# Auth/crypto files with bus factor <= 1
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out files --tag auth --bus-factor-max 1
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out files --tag crypto --bus-factor-max 1
# Who is touching sensitive code the most
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out people --sort sensitive_touches --limit 10
# Co-change neighbors (cluster hints for ownership drift)
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out cochange --file path/to/file --min-jaccard 0.05 --limit 20
# Community maintainers (for a cluster)
python skills/skills/security-ownership-map/scripts/query_ownership.py --data-dir ownership-map-out community --id 3
# Monthly maintainers for the community containing a file
python skills/skills/security-ownership-map/scripts/community_maintainers.py \
--data-dir ownership-map-out \
--file network/card.c \
--since 2025-01-01 \
--top 5
# Quarterly buckets instead of monthly
python skills/skills/security-ownership-map/scripts/community_maintainers.py \
--data-dir ownership-map-out \
--file network/card.c \
--since 2025-01-01 \
--bucket quarter \
--top 5
Notes:
--touch-mode file to count per-file touches.--window-days 90 or --weight recency --half-life-days 180 to smooth churn.--ignore-author-regex '(bot|dependabot)'.--min-share 0.1 to show stable maintainers only.--bucket quarter for calendar quarter groupings.--identity committer or --date-field committer to switch from author attribution.--include-merges to include merge commits (excluded by default).Use this structure, add fields if needed:
{
"orphaned_sensitive_code": [
{
"path": "crypto/tls/handshake.rs",
"last_security_touch": "2023-03-12T18:10:04+00:00",
"bus_factor": 1
}
],
"hidden_owners": [
{
"person": "alice@corp",
"controls": "63% of auth code"
}
]
}
Use references/neo4j-import.md when you need to load the CSVs into Neo4j. It includes constraints, import Cypher, and visualization tips.
bus_factor_hotspots in summary.json lists sensitive files with low bus factor; orphaned_sensitive_code is the stale subset.git log is too large, narrow with --since or --until.summary.json against CODEOWNERS to highlight ownership drift.
