What it does

Prime Sync is an agent skill from avibebuilder/claude-prime. Syncs Claude config between prime repo and target projects. Trigger on 'sync', 'prime-sync', 'push config', 'pull config', 'update prime', 'sync claude config'. Push mode deploys to targets; pull mode imports changes back.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: You've heard Claude Code can do amazing things. Skills, hooks, agents, memory systems — but who has time to figure all that out? Claude Prime sets it up for you in one command. The licence is MIT.

When your agent uses it

  • Sync claude config

Example prompts

  • “prime-sync”
  • “push config”
  • “pull config”
  • “/prime-sync”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Validate Target
  2. Parallel Analysis
  3. Build Sync Plan
  4. Handle Conflicts
  5. Execute Sync
  6. Report

What it can do on your machine

Read from SKILL.md and the folder at commit 80bcfa4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • 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

Prime Sync loads about 1.2k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 583 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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); files beside SKILL.md are not scanned.

Mode Detection

Detect operating mode before anything else:

  1. VERSION file exists in CWD → push mode (CWD is the prime repo)
  2. .claude/.prime-version exists in CWD → pull mode (CWD is a target project)
  3. Neither detected → ask user which mode and for the required path

Push Mode — Resolve Target

Source = CWD (prime repo). Target = resolved project path.

State file: .claude/prime-projects.json

Tracks known target paths, last sync time, and version. Shape:

json
{ "projects": [{ "path": "/absolute/path", "lastSynced": "2025-12-30T10:30:00Z", "version": "1.4.2" }] }

Create as { "projects": [] } if missing.

Resolution flow:

  1. Argument provided → Use that path, then record it after a successful sync
  2. No argument, known projects exist → Ask the user which project(s) to sync, including an All projects option
  3. No argument, no known projects → Ask the user for a path

State file management:

  • Create .claude/ only if you need to persist the state file
  • Update the synced project's time/version only after a successful sync
  • Keep one entry per absolute path

Pull Mode — Clone Prime

Source = cloned prime repo. Target = CWD.

Flow:

  1. Read current version from .claude/.prime-version in CWD
  2. Generate timestamp: date +%Y%m%d%H%M%S
  3. Clone prime repo: git clone https://github.com/avibebuilder/claude-prime.git /tmp/claude-prime-sync-<timestamp>/
  4. Set source = /tmp/claude-prime-sync-<timestamp>/, target = CWD
  5. Continue to shared process below
  6. Clean up /tmp/claude-prime-sync-<timestamp>/ after sync completes (success or failure)

No state file in pull mode — the target project is self-contained.

Process

1. Validate Target
  • Check that the target path exists, is a directory, and is not the same location as the source repo
  • Treat a valid target as a project root where writing .claude/ is appropriate
  • Read versions from target (.claude/.prime-version) and prime (VERSION)

If the path fails those checks, abort and explain why.

2. Parallel Analysis

Change Detection:

  • Detect relevant changes in prime's .claude/ based on the target's recorded version state
  • If the target has no recorded version, or already matches the current prime version, sync only uncommitted prime changes
  • If the target is on an older prime version, diff from that version tag to HEAD and include uncommitted changes; warn if the tag is missing
  • Categorize changes into commands, agents, hooks, settings, skills, and starter-skills

Stack Detection (only if skills or starter-skills changed): check target for stack indicators relevant to each changed skill/starter.

File Comparison: compare each changed file with target. Detect: NEW, UPDATE, IDENTICAL, CONFLICT.

Show full SKILL.md (209 more words)Show less
3. Build Sync Plan

Aggregate results and present:

CHANGED (will sync): ...
IDENTICAL (skip): ...
CONFLICTS (will ask): ...
IRRELEVANT (skip, wrong stack): ...

GATE: User approves sync plan.

4. Handle Conflicts

For each conflict, show the relevant diff and ask the user how to proceed:

  • Overwrite — Replace the target copy with the prime version
  • Skip — Leave the target copy unchanged
  • Merge — Surface the full diff and let the user choose which parts to keep before writing anything
5. Execute Sync
  1. Create .claude/ in target if needed
  2. Copy approved files (skills as entire folders)
  3. Sync approved starter-skills to .claude/starter-skills/ in target
  4. Update .prime-version with prime's VERSION
6. Report
Sync complete! (prime vX.X.X)
Updated: ...
Skipped: ...
Version: X.X.X → written to .prime-version

Push mode only: update state file (lastSynced timestamp + version). Pull mode only: clean up /tmp/claude-prime-sync-* clone directory.

Gotchas

  • prime-sync stays in prime — do not copy this skill into target projects.
  • Push and pull keep different state — state file is push-only; pull mode treats the target as self-contained.
  • Version history can be incomplete — if the expected tag is missing, warn and continue with that uncertainty explicit.

Constraints

  • NEVER modify the target project's source code
  • NEVER sync without user approval at the plan gate
  • In push mode, preserve one state entry per target path and update it only after success
  • In pull mode, always clean up the temporary clone, even on failure
