Claude Code Multi-Provider Profiles

Overview

This skill creates an isolated-but-shared profile system for Claude Code CLI. Each profile gets its own .claude.json state file (credentials and session history) while sharing skills, projects, hook scripts, agents, and installed plugin state across all profiles — and converging each profile's settings.json (hook registration, marketplaces, env feature flags, permissions, preferences) from the default profile, so the only intended difference between profiles is the model/provider.

The result: you can open one terminal with Kimi, another with DeepSeek, another with Anthropic — each running as a fully independent Claude Code process, without configuration bleed.

How It Works

• CLAUDE_CONFIG_DIR tells Claude Code CLI which directory to use as its config root.
• Each profile lives in ~/.claude-profiles/<name>/ with an isolated .claude.json.
• Content directories (skills/, projects/, hooks/, agents/, settings/) are symlinked back to the main ~/.claude/ directory so you only maintain one copy. Note this shares hook scripts, not hook registration — registration lives in each profile's own settings.json (next bullet).
• Config layer — settings.json: each profile has its own settings.json (Claude Code treats it as config-dir-local), so everything stored there — hook registration, extraKnownMarketplaces, enabledPlugins, env feature flags, permissions, behavior preferences — silently drifts the moment it changes in the default profile (measured 2026-07-18: 9/9 real profiles had zero hook registrations). sync-profile-settings.py is the converger: registered as a SessionStart hook, it copies every key from the default profile's settings.json into the active profile's, except identity keys (top-level model; and env vars that carry provider routing or Anthropic-native isolation — ANTHROPIC_*, CLAUDE_CODE_SUBAGENT_MODEL, ENABLE_TOOL_SEARCH, DISABLE_GROWTHBOOK/TELEMETRY/AUTOUPDATER — which the provider settings file deliberately sets differently). Profile-only keys are preserved; the sync never deletes. This is what makes "everything except the model works in every profile" actually hold.
• Exception — plugins/: marketplace content and install state are shared, but each profile keeps its own known_marketplaces.json. Claude validates a marketplace's installLocation with path.resolve() (which does NOT resolve symlinks), so a single shared file would make every non-writing profile report "corrupted installLocation". claude-plugins-sync.py builds and maintains this per-profile structure.
• claude-plugins-sync.py also mirrors enabledPlugins from the default ~/.claude/settings.json into each profile's settings.json (sharing cache files is not enough; Claude Code treats "enabled" state as config-dir-local). The SessionStart converger above covers the same key as part of its whole-settings sync; claude-plugins-sync.py remains the owner of the per-profile known_marketplaces.json structure.
• Local source sync is automatic on maintainer machines. Installed Claude plugin cache directories and Codex/agents skill copies are symlinked to the source repos, so normal source edits are live immediately. sync-local-skill-sources.py is the idempotent repair primitive; claude-profile init/launch runs it automatically, and sync-local-skill-sources-daemon.sh --install installs a macOS LaunchAgent that watches default Claude install state plus local marketplace manifests for structural changes. When a skill is removed from a marketplace manifest, the same repair pass prunes only stale Codex/agents symlinks that point back into the managed source repos; it never deletes real skill directories.
  • Pitfalls with daemon-owned symlinks (both observed 2026-07): ① never hand-create a symlink into a daemon-owned directory (ln -s <repo>/<skill> ~/.codex/skills/<skill>) — if the daemon already created it, BSD ln puts the new link inside the target directory, leaving a self-referential <skill>/<skill> stray that directory walks can recurse into; repair by hand only with ln -sfn, or after readlink confirms the link is missing. ② Verify symlinks with readlink, not ls -la <link> — ls follows the link and lists the target's contents, which reads as "link created" even when the actual outcome was a stray inside the target.
• Sync scripts use a shared cross-process lock. This is required because users often open several provider windows from tmux or multiple terminals at once; concurrent launches must serialize marketplace/cache rewrites while still allowing all profiles to start.
• For the full local-source architecture, read references/local-source-sync-architecture.md before changing these scripts.
• Provider routing is done via ~/.claude/settings/<name>.json, which sets ANTHROPIC_MODEL, ANTHROPIC_BASE_URL, and ANTHROPIC_AUTH_TOKEN for that window.

One-Click Setup Workflow

When the user says something like "set up Claude Code profiles" or "I want to use Kimi and DeepSeek in different windows":

1. Check prerequisites

   • claude CLI is installed: which claude
   • Shell is zsh or bash: detect via $SHELL
   • python3 is available

2. Install the profile manager scripts

   • Copy scripts/claude-profiles.sh to ~/.config/claude-switch-models-setup/claude-profiles.sh
   • Copy scripts/claude-plugins-sync.py to ~/.config/claude-switch-models-setup/claude-plugins-sync.py
   • Copy scripts/sync-local-skill-sources.py to ~/.config/claude-switch-models-setup/sync-local-skill-sources.py
   • Copy scripts/sync-local-skill-sources-daemon.sh to ~/.config/claude-switch-models-setup/sync-local-skill-sources-daemon.sh
   • Copy scripts/sync-profile-settings.py to ~/.config/claude-switch-models-setup/sync-profile-settings.py
   • Make all five executable

3. Add shell integration

   • Source the profile manager in ~/.zshrc or ~/.bashrc
   • Add aliases: csk, csks, csd, csg, css, cssp
   • Tell the user to run source ~/.zshrc (or open a new terminal)

4. Generate provider settings files

   • For each provider the user wants, create ~/.claude/settings/<provider>.json
   • Use the templates in assets/templates/ as a starting point
   • Prompt the user for their API key and base URL; never hardcode defaults
   • Set the context window correctly for this specific provider — [1m] suffix vs explicit CLAUDE_CODE_MAX_CONTEXT_TOKENS/CLAUDE_CODE_AUTO_COMPACT_WINDOW, see "Configuring Context Window Size" below. Do this explicitly for every new profile rather than copying whatever the nearest template happens to already have — the nearest template not needing it is not evidence that this one doesn't either.
   • Include the required isolation flags:
     • CLAUDE_CODE_SUBAGENT_MODEL (same as ANTHROPIC_MODEL)
     • ENABLE_TOOL_SEARCH: "false"
     • DISABLE_GROWTHBOOK: "1"
     • DISABLE_TELEMETRY: "1"
     • DISABLE_AUTOUPDATER: "1"

5. Initialize profile directories

   • Run claude-profiles-init
   • This creates ~/.claude-profiles/<provider>/ with isolated .claude.json and symlinks
   • On maintainer machines, this also repairs local source symlinks before syncing plugin metadata

   Statusline wiring: claude-profiles-init auto-detects a statusline script from ~/.claude/settings.json or ~/.claude/statusline.sh and injects it into each new profile. If neither is present, profiles will work but without a status bar. It is the AI's job to decide whether the user needs a statusline, install the statusline-generator skill if appropriate, and run its installer — not the profile setup script. Do not hardcode dependency installs into shell scripts.

6. Register the settings converger

   • Add ~/.config/claude-switch-models-setup/sync-profile-settings.py as a SessionStart hook in the default profile's ~/.claude/settings.json hooks.SessionStart list (it no-ops when the active profile IS the default; its job there is to propagate into every profile's own hooks key on the first sync)
   • Run the initial alignment: python3 ~/.config/claude-switch-models-setup/sync-profile-settings.py --all
   • From then on every profile converges its settings.json from the default profile at each session start (changes apply next session). Audit without writing: --check --all

7. Verify isolation

   • Run claude-profiles-doctor
   • Confirm each profile directory has .claude.json and valid symlinks

8. Install automatic local source sync for maintainers

   • Skip this for normal students or users who do not edit the skill source repos
   • On a maintainer macOS machine, run sync-local-skill-sources-daemon.sh --install
   • This watches default Claude install state plus local marketplace manifests and repairs Claude/Codex installed copies automatically after install/uninstall or plugin topology changes

9. Show the user how to launch

   • csk → Kimi K3 window
   • csks → Kimi K2.7 highspeed window
   • csd → DeepSeek window
   • csg → GLM window
   • css → StepFun window
   • cssp → StepFun paid/account-specific window, when step-pay.json exists
   • claude (no alias) → default Anthropic profile

Commands

After setup, the user can run:

claude-profiles-init          # Re-scan settings/*.json, create missing profiles;
                               # reports symlink drift (real dirs that should be symlinks).
                               # Add --repair to archive drift and replace with symlinks.
claude-profile <name>         # Launch a specific profile
claude-profiles-ls            # List profiles
claude-profiles-doctor        # Check symlink health
claude-profile-rm <name>      # Remove a profile's isolation directory
python3 ~/.config/claude-switch-models-setup/claude-plugins-sync.py
                               # Repair per-profile plugin structure and enabledPlugins
python3 ~/.config/claude-switch-models-setup/sync-profile-settings.py --all
                               # Converge every profile's settings.json from the default
                               # profile (hooks, marketplaces, env flags, permissions,
                               # preferences); --check --all audits without writing
python3 ~/.config/claude-switch-models-setup/sync-local-skill-sources.py --apply
                               # Maintainers: one-shot repair for Claude/Codex source symlinks
~/.config/claude-switch-models-setup/sync-local-skill-sources-daemon.sh --install
                               # Maintainers: install automatic macOS watcher

These are not day-to-day commands. Normal source edits are live through symlinks. The one-shot commands are for repair, bootstrap, or non-macOS environments without the LaunchAgent watcher.

Provider Templates

Templates live in assets/templates/:

• kimi.json — Kimi K3 (1M context via the [1m] marker — see "Configuring Context Window Size" below)
• kimi-highspeed.json — Kimi K2.7 highspeed (legacy 200K context)
• glm.json
• deepseek.json
• stepfun.json
• anthropic.json

Each template has placeholders for <API_KEY> and <BASE_URL>. Ask the user for real values; do not guess or reuse values from the current machine unless the user explicitly provides them.

Configuring Context Window Size

Every provider template sets the model's context window one of two ways — get this wrong and Claude Code doesn't know how much context the model can actually hold. Undershoot and it compacts (summarizes, drops old detail) far earlier than the provider actually requires; overshoot and it won't compact until the real limit is already blown past.

The full client-side mechanism of the [1m] marker — what it strips off the model field, what it adds to the anthropic-beta header, and why a missing [1m] does not mean the provider can't hold a big prompt — is documented in references/context-window-config.md. Reach for it when a context number looks wrong, not at template-writing time.

Decision rule

When writing a new provider's settings/<name>.json, pick based on the provider's real, verified context window — not the model's marketing name, and not by copying whatever the nearest template happens to do:

deepseek.json and glm.json set both [1m] and an explicit CLAUDE_CODE_AUTO_COMPACT_WINDOW: "1000000". That's belt-and-suspenders, not redundant filler to strip out — the exact precedence between the marker and the explicit override hasn't been independently reverse-engineered, so if you're copying one of those two templates, keep both rather than dropping one.

The full step-2-16k template-correctness war-story (why an internally-consistent-looking context value is not the same as a currently-correct one — cross-check the model name against the provider's live docs, not just the numbers around it), plus a reusable recipe to verify whether any env var actually changes the bytes sent over the wire (a local http.server capture, since --debug api only shows internal state), live in references/context-window-config.md.

Common base URLs (verify with your provider)

Important: The exact endpoint depends on whether the user is calling the provider directly or through a compatibility gateway (e.g., OpenRouter). Always ask.

Shared vs. Isolated

Troubleshooting

A profile directory exists but claude-profiles-doctor reports it as an "orphan profile"

Symptom: claude-profiles-doctor reports WARN: orphan profile — no settings/<name>.json; claude-profile <name> fails. Run: claude-profile-rm <name>.

Cause: the profile isolation directory exists under ~/.claude-profiles/ but the corresponding ~/.claude/settings/<name>.json provider config file is missing. claude-profiles-init only scans settings/*.json, so an orphan profile's symlinks are never created or maintained, and claude-profile <name> will fail to launch with "Error: Settings file not found." The profile directory may still contain useful per-profile data (history.jsonl, .claude.json with provider credentials, settings.json, skill workspaces).

Fix:

• If the profile is no longer needed: claude-profile-rm <name> — this safely removes the isolation directory (it checks for unexpected files first).
• If you want to revive it: recreate the settings file at ~/.claude/settings/<name>.json (use a provider template from assets/templates/), then run claude-profiles-init.

A shared directory (skills/projects/hooks/agents/...) shows as a real directory, not a symlink

Symptom: claude-profiles-doctor reports <name> is a real directory (expected symlink to ~/.claude/<name>) — drift; run: claude-profiles-init --repair.

Cause: the profile was created before the symlink-convergence design landed (or was hand-created), so a shared content directory ended up as a real per-profile directory instead of a symlink. That profile's copy now silently diverges from the main ~/.claude/ copy — its skills/projects/hooks/agents are not the same as every other profile's. The broken-symlink check cannot see this (a real directory is not a broken link); on a real machine this drift went undetected for months until the dedicated real-directory check was added (2026-07-21: legacy profiles created before this check existed carried real projects/ dirs for months, undetected).

Fix (reversible — data is archived, never deleted):

claude-profiles-init --repair

For each drifted directory this archives the real dir to <name>.pre-symlink-bak-<timestamp> inside the profile directory, then creates the symlink that should have been there. Run claude-profiles-doctor again to confirm a clean bill. If an archive turns out to hold data you need, it is sitting right there — nothing was destroyed.

Note on what gets shared: after repair, that directory points at the main ~/.claude/<name> copy, so the profile sees the same skills/projects/etc. as the default profile — which is the entire point of the shared-symlink design. The per-profile state that must stay isolated (.claude.json, settings.json identity keys like model/provider env, plugins/known_marketplaces.json) is never one of these symlinked dirs, so repair never touches it. Inspect the archive before discarding it if the profile held session/history data you care about — those would now resolve to the shared copy.

Marketplace says "corrupted installLocation"

Symptom: /plugin or claude plugin marketplace update reports corrupted installLocation ... expected a path inside <config-dir>/plugins/marketplaces.

Cause: known_marketplaces.json ended up shared across profiles (or hand-edited). Its installLocation is config-dir-specific because Claude validates with path.resolve() (symlinks NOT resolved), so one shared copy cannot satisfy multiple profiles.

Fix: claude-plugins-sync.py rebuilds each profile's own copy + the shared-content symlinks. It runs automatically at claude-profile init/launch; to run manually:

python3 ~/.config/claude-switch-models-setup/claude-plugins-sync.py

Skill exists in default Claude but is missing in Kimi/GLM/DeepSeek

Symptom: the default Anthropic profile can see a skill, but a third-party profile cannot.

Cause: Claude Code stores enabledPlugins in each config directory's settings.json. Sharing plugins/cache only makes files available; it does not enable them.

Fix:

python3 ~/.config/claude-switch-models-setup/claude-plugins-sync.py

Then restart the affected Claude Code window.

Local source edits do not show up in Claude Code or Codex

Symptom: you edit a skill in a local source repo, but Claude Code or Codex still loads an old installed copy.

Expected design: normal edits to existing source files are live immediately because the installed locations are symlinks. Existing Claude Code/Codex sessions may still need a restart because skill metadata is loaded at session start.

If the edit is structural (new plugin, new skill entry, version bump, install/uninstall, or marketplace manifest change), the macOS LaunchAgent should run automatically. Check:

launchctl print gui/$(id -u)/ai.daymade.claude-skill-source-sync

Repair manually only if the watcher is not installed or you are on a non-macOS machine:

python3 ~/.config/claude-switch-models-setup/sync-local-skill-sources.py --apply

This moves existing real copies into timestamped .source-sync-backups/ folders, replaces them with symlinks to the source repos, and prunes stale managed symlinks after a skill is removed from the manifest.

A profile is missing hooks, marketplaces, env flags, or other default-profile settings

Symptom: the default profile has hook guards, marketplaces, or feature flags configured, but a third-party profile behaves as if they don't exist (no PreToolUse guards fire, claude plugin marketplace list is empty, a feature enabled in the default profile is off).

Cause: those live in each profile's own settings.json, which is config-dir-local — symlinking directories does not cover the config layer, and it drifts silently the moment the default profile changes.

Fix:

python3 ~/.config/claude-switch-models-setup/sync-profile-settings.py --all

Then restart the affected window. Once the converger is registered as a SessionStart hook (setup step 6), every profile self-converges at session start, so this should only be needed after a manual settings edit you want propagated immediately.

Third-party profile tries to use Anthropic-specific features

Symptom: WebSearch or other Anthropic-native tools fail with 400 errors. Fix: Ensure the profile's settings.json sets:

{
  "env": {
    "ENABLE_TOOL_SEARCH": "false",
    "DISABLE_GROWTHBOOK": "1",
    "DISABLE_TELEMETRY": "1",
    "DISABLE_AUTOUPDATER": "1"
  }
}

Subagent calls fall back to a different model

Symptom: Subagents inside a Kimi window call claude-opus-4-7. Fix: Set CLAUDE_CODE_SUBAGENT_MODEL to the same value as ANTHROPIC_MODEL in the profile's settings.json.

A huge-context provider compacts/summarizes way too early, or the statusline context number looks wrong

Symptom: a provider whose own docs claim ~1M tokens of context gets auto-compacted by Claude Code well below that — long sessions get summarized when there's clearly no real need to yet, or the context percentage in the statusline tracks like it's looking at a ~200K model instead of the real ceiling.

Cause: the profile's ANTHROPIC_MODEL (and its ANTHROPIC_DEFAULT_*_MODEL / CLAUDE_CODE_SUBAGENT_MODEL siblings) is missing the [1m] marker. Claude Code has no other way to learn the provider's real context size — the request itself succeeding with a huge prompt doesn't tell Claude Code anything, since that's a property of the upstream provider, not of the client. See references/context-window-config.md for the full mechanism.

Fix: add the literal [1m] suffix to ANTHROPIC_MODEL, every ANTHROPIC_DEFAULT_*_MODEL, and CLAUDE_CODE_SUBAGENT_MODEL in the profile's settings.json (match kimi.json's pattern). Restart the affected window.

Adding a New Provider Later

1. Create ~/.claude/settings/<new-provider>.json using a template.
2. Check the provider's real, verified context window and configure it — [1m] marker or explicit CLAUDE_CODE_MAX_CONTEXT_TOKENS/CLAUDE_CODE_AUTO_COMPACT_WINDOW, see "Configuring Context Window Size" below and references/context-window-config.md. Don't skip this because the template you copied from happened not to need it.
3. Run claude-profiles-init.
4. Add an alias to the shell rc file if desired.

Security Notes

• API keys are written to ~/.claude/settings/<provider>.json in plain text, the same way Claude Code stores ANTHROPIC_AUTH_TOKEN. This matches Claude Code's own security model.
• This skill never uploads keys or settings anywhere.
• For public distribution, the bundled scripts contain no hardcoded secrets, endpoints, or user-specific paths.

Next Step

After setup, the user can immediately test by opening two terminals and running csk (Kimi K3) in one and csd in the other. Each window is independent.
