What it does

Cross Repo Cache is an agent skill from closedloop-ai/claude-plugins. Check if cross-repo coordinator results can be reused, avoiding redundant Sonnet agent launches. Compares peer repo git hashes against stored hashes from last coordinator run. Triggers on: entering Phase 1.4.1, checking cross-repo cache, before discovering peers. Returns CROSSREPOCACHEHIT with cached status or CROSSREPOCACHEMISS to re-run coordinator.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/check_cross_repo_cache.sh`).

It sits in Development. It works with Git. The repository describes itself as: Open-source Claude Code plugins for multi-agent software delivery. Plan-first SDLC workflow, code review, LLM quality judges, and self-learning — grounded in your codebase… The licence is Apache-2.0.

Requirements

Python 3
A Bash shell
Pre-approved tools (allowed-tools): Bash

What it can do on your machine

Read from SKILL.md and the folder at commit 476b54c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
- bash
- python3
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cross Repo Cache loads about 683 tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 177 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~94
When it runs · the whole SKILL.md, loaded when a task matches: ~683

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Cross-Repo Cache Skill

Check whether prior cross-repo coordinator results are still valid, avoiding redundant Sonnet agent launches when peer repositories haven't changed.

When to Use

Activate this skill at the start of Phase 1.4.1 (Discover peers), before launching @code:cross-repo-coordinator. If the cache is fresh, skip the coordinator and use cached results.

Usage

Check Cache (Phase 1.4.1)

bash

bash ${CLAUDE_SKILL_DIR}/scripts/check_cross_repo_cache.sh <WORKDIR>

Stamp Cache (after coordinator completes)

After the cross-repo-coordinator runs successfully, stamp the cache:

bash

# Compute hash of peer repo states
if [ -f ".workspace-repos.json" ]; then
  repo_hashes=""
  for repo_path in $(python3 -c "import json; [print(r['path']) for r in json.load(open('.workspace-repos.json')) if r.get('path')]" 2>/dev/null); do
    [ -d "$repo_path/.git" ] && repo_hashes="$repo_hashes$repo_path:$(git -C "$repo_path" rev-parse HEAD 2>/dev/null || echo unknown) "
  done
  echo "$repo_hashes" | shasum -a 256 > $WORKDIR/.cross-repo-hash
else
  shasum -a 256 $WORKDIR/.cross-repo-needs.json > $WORKDIR/.cross-repo-hash
fi

Interpreting Output

Cache Hit

CROSS_REPO_CACHE_HIT
status: NO_CROSS_REPO_NEEDED | CAPABILITIES_IDENTIFIED
capabilities:
  - peer-name: capability description

Action:

If status is NO_CROSS_REPO_NEEDED: Mark 1.4.x phases complete, proceed to Phase 2
If status is CAPABILITIES_IDENTIFIED: Skip coordinator, proceed to Phase 1.4.2 with cached capabilities

Cache Miss

CROSS_REPO_CACHE_MISS
reason: <why the cache is stale or missing>

Action: Launch @code:cross-repo-coordinator as normal. After it completes, stamp the cache.

How Freshness Works

The script hashes the git HEAD commit of each peer repository listed in .workspace-repos.json. If any peer has new commits, the hash changes and the coordinator re-runs. This correctly handles the case where a peer repo is updated between iterations.

Cache Location

Coordinator results: $WORKDIR/.cross-repo-needs.json (written by coordinator)
Cache hash: $WORKDIR/.cross-repo-hash (written by stamp step)
Per-repo cache: .learnings/cross-repo-cache/{repo-name}/ (used by generic-discovery agents)

Can I use Cross Repo Cache in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add closedloop-ai/claude-plugins --skill cross-repo-cache -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cross-repo-cache, .gemini/skills/cross-repo-cache, .github/skills/cross-repo-cache and .opencode/skills/cross-repo-cache in your project.
