# claude-profile

## Purpose

Launch Claude Code with a named configuration profile and an engagement mode. The profile selects which `~/.claude-*` config directory to use (and optionally embeds non-Anthropic provider config); the engagement mode bundles a driver model, subagent policy, async tolerance, and workflow stance.

## Usage

```
claude-profile [OPTIONS] [PROFILE] [-- CLAUDE_ARGS...]
```

### Arguments

| Argument | Default | Description |
|----------|---------|-------------|
| `PROFILE` | (interactive picker) | Name of a profile under `~/.claude-<PROFILE>/`. Pass `default` to use `~/.claude/`. |
| `CLAUDE_ARGS` | (none) | Arguments after `--` are passed through to `claude` unchanged. |

### Options

| Flag | Description |
|------|-------------|
| `--mode <NAME>` | Skip the mode picker and use the named mode (`chat`, `quick`, `deep`, `deep-fable`, `hybrid`, `orch`). |
| `--preset <NAME>` | Use a named preset from the active profile's `presets.yaml`. Sets profile, mode, and any preset-defined defaults in one shot. |
| `--project <NAME>` | Pre-select a project (skips the project question for modes that ask it). |
| `--dryrun`, `-n` | Print all resolved values and the command that would be executed; do not launch `claude`, do not write `active-mode.env` or `last-mode`. |
| `--help`, `-h` | Show usage. |

### Mutual exclusion

- `--preset` is mutually exclusive with `--mode` and `--project` — the preset defines all of those. Passing both is an error.
- A positional `PROFILE` combined with `--preset` is allowed only if the preset's `profile` field matches; mismatch is an error.

## Behaviour

The script runs in three phases: **profile selection**, **mode selection**, **launch**. Each phase has an interactive path (prompt the user) and a non-interactive path (CLI flag or config file).

### Phase 1 — Profile selection

1. If `--preset <name>` is given, read the preset from the global presets file (see "File contracts" below) and use its `profile` field. Skip the rest of phase 1.
2. Else if `PROFILE` is given as a positional argument, use it directly.
3. Else (interactive): list profiles by scanning `~/.claude-*` directories, display a numbered menu, prompt for selection. Default selection is `default` (`~/.claude/`).
4. Resolve the profile to a directory: `default` → `~/.claude/`; otherwise `~/.claude-<NAME>/`.
5. If the directory does not exist, error and exit 1.
6. Export `CLAUDE_CONFIG_DIR=<resolved>`.
7. Emit the WezTerm theme escape sequence for the profile (existing behaviour, unchanged).

### Phase 2 — Mode selection

1. If `--preset` is given, use the preset's `mode` and any other fields (project, async, autoloop). Skip the rest of phase 2.
2. Else if `--mode <name>` is given, use it.
3. Else (interactive): list available modes by scanning `<repo>/data/claude-profile/modes/*.md`, display a numbered menu with each mode's `tag` and the first sentence of its `## Purpose` section. Default selection is the contents of `$CLAUDE_CONFIG_DIR/last-mode` (if present), else `quick`.
4. Validate the chosen mode file exists at `<repo>/data/claude-profile/modes/<name>.md`. If not, error and exit 1.
5. Read the mode file's frontmatter to extract `driver`, `tag`, `async_ok`, `autoloop`, `plan_mode_auto`, `spec_driven`, `escalates_to`.

### Model ID resolution

The model ID is determined by combining the mode's `driver` field with the profile's optional `provider.env`:

1. Map the driver to an Anthropic model ID using the hardcoded table:

| Driver | Model ID |
|---|---|
| `haiku` | `claude-haiku-4-5-20251001` |
| `sonnet` | `claude-sonnet-4-6` |
| `opus` | `claude-opus-4-8` |
| `opus-1m` | `claude-opus-4-8[1m]` (Opus 4.8 has 1M context natively; `opus-1m` is retained for the `[1m]` launch convention) |
| `fable` | `claude-fable-5` |

2. If `$CLAUDE_CONFIG_DIR/provider.env` exists, parse it. If it contains a `MODEL_ID` entry, use that instead of the hardcoded default.

This means Anthropic profiles need no extra config. Non-Anthropic profiles embed their model and API config in `provider.env`.

**Project selection is intentionally NOT asked by claude-profile.** The existing CLAUDE.md session-start flow handles project selection once `claude` is running. claude-profile accepts `--project <name>` as a non-interactive override (for presets and scripted launches), which writes `CLAUDE_PROJECT` into `active-mode.env`.

### Phase 3 — Launch

1. Write the resolved values to `$CLAUDE_CONFIG_DIR/active-mode.env` (key=value, one per line, see "File contracts").
2. Write the chosen mode name to `$CLAUDE_CONFIG_DIR/last-mode`.
3. Read the mode file's prose body (everything after the frontmatter) and append it to the context that `context-load` produces. The mode body becomes part of `--append-system-prompt`.
4. Set `CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING=1` (existing behaviour).
5. Set `COLORTERM=truecolor` for proper colour support.
6. If `provider.env` specifies `ANTHROPIC_BASE_URL`, export it.
7. If `provider.env` specifies `ANTHROPIC_API_KEY_FILE`, read the key from the file and export it as `ANTHROPIC_API_KEY`. Error if the file is missing.
8. Export any other entries from `provider.env` as environment variables.
9. Execute `claude --model "<model_id>" --append-system-prompt "$context_plus_mode" "${CLAUDE_ARGS[@]}"`.
10. On exit, the existing WezTerm reset trap runs.

## File contracts

### Mode files — `<repo>/data/claude-profile/modes/<name>.md`

YAML frontmatter (machine-readable) + markdown body (read by the driver model). Required frontmatter fields:

```yaml
name: <short name, matches filename>
tag: <status-line tag, ≤8 chars>
driver: <haiku|sonnet|opus|opus-1m|fable>
async_ok: <yes|no>
autoloop: <none|"/loop 2m /orchestrate"|other slash command>
plan_mode_auto: <yes|no>
spec_driven: <yes|no>
escalates_to: <none|opus>  # used by statusline to render →Opus arrow
```

The body must include sections (in order): `## Purpose`, `## Driver constraint`, `## Subagent policy`, `## Reasoning posture`, `## Async policy`, `## Workflow stance`, `## Auto-fire at session start`, `## Status line format`, `## Escalation triggers`, `## Out of scope`, `## On context wipe (/clear)`. `## Named workflows available` is optional.

### Profile provider config — `$CLAUDE_CONFIG_DIR/provider.env`

Optional. Only needed for non-Anthropic profiles. Plain key=value format (no quoting, no shell expansion):

```
MODEL_ID=MiniMax-M2.7
ANTHROPIC_BASE_URL=https://api.minimax.io/anthropic
ANTHROPIC_API_KEY_FILE=~/.claude-secrets/minimax-auth-token
ANTHROPIC_MODEL=MiniMax-M2.7
ANTHROPIC_SMALL_FAST_MODEL=MiniMax-M2.7
API_TIMEOUT_MS=3000000
```

Reserved keys with special handling:
- `MODEL_ID` — overrides the driver→model_id mapping; passed to `claude --model`
- `ANTHROPIC_BASE_URL` — exported as-is
- `ANTHROPIC_API_KEY_FILE` — file is read and its contents exported as `ANTHROPIC_API_KEY`

All other keys are exported as environment variables unchanged.

### Active mode env — `$CLAUDE_CONFIG_DIR/active-mode.env`

Written on every launch, overwritten each time. Read by:
- The status-line script (to render the mode tag)
- CLAUDE.md session-start hook (to re-apply the mode after `/clear`)

```
CLAUDE_MODE=deep
CLAUDE_MODE_TAG=deep
CLAUDE_DRIVER=sonnet
CLAUDE_ESCALATES_TO=opus
CLAUDE_PROJECT=cluster-bootstrap
CLAUDE_ASYNC_OK=yes
CLAUDE_AUTOLOOP=none
CLAUDE_PLAN_MODE_AUTO=yes
CLAUDE_SPEC_DRIVEN=yes
CLAUDE_MODE_FILE=/home/paul/dev/claude/small-scripts/data/claude-profile/modes/deep.md
```

### Last mode — `$CLAUDE_CONFIG_DIR/last-mode`

Single line: the mode name. Used as the default in the next interactive picker.

### Presets — `$CLAUDE_CONFIG_DIR/presets.yaml`

Per-profile, user-edited. Each preset is a named bundle of answers to the picker:

```yaml
deep-cluster:
  profile: oreillyit-anthropic
  mode: deep
  project: cluster-bootstrap
  async: yes

quick-skills:
  profile: oreillyit-anthropic
  mode: quick
  project: small-scripts

quick-minimax:
  profile: oreillyit-minimax
  mode: quick
  project: small-scripts
```

The `profile` field is required. See `data/claude-profile/presets.yaml.example` for a full example.

## Status line integration

The status-line script (`~/.claude/status/statusline.sh`) reads `$CLAUDE_CONFIG_DIR/active-mode.env` when `CLAUDE_CONFIG_DIR` is set. It uses `CLAUDE_DRIVER` and `CLAUDE_ESCALATES_TO` to build the model bracket, and `CLAUDE_MODE_TAG` to prefix the topic:

```
[Sonnet→Opus] deep · cluster-bootstrap: M10 Gitea CI | 23% ctx
```

- `escalates_to: opus` → `[Sonnet→Opus]` (shows escalation path)
- `escalates_to: none` → `[Sonnet]` (no arrow)
- Mode tag is prepended to the topic with `·` separator

If `active-mode.env` is missing or `CLAUDE_CONFIG_DIR` is unset, the status line falls back to the full model display name from the session JSON with no mode tag.

## Dryrun behaviour

When `--dryrun` (or `-n`) is passed, claude-profile resolves all values exactly as it would in a real run, then prints them and exits 0 — no `claude` invocation, no file writes.

```
$ claude-profile --dryrun --preset deep-cluster
[dryrun] Profile:         oreillyit-anthropic (~/.claude-oreillyit-anthropic)
[dryrun] Mode:            deep
[dryrun] Mode file:       ~/dev/claude/small-scripts/data/claude-profile/modes/deep.md
[dryrun] Driver:          sonnet
[dryrun] Model ID:        claude-sonnet-4-6
[dryrun] Project:         cluster-bootstrap
[dryrun] Async OK:        yes
[dryrun] Autoloop:        none
[dryrun] Would write:     ~/.claude-oreillyit-anthropic/active-mode.env
[dryrun] Would write:     ~/.claude-oreillyit-anthropic/last-mode
[dryrun] Would execute:   claude --model claude-sonnet-4-6 --append-system-prompt "<context+mode>"
[dryrun] Context length:  4823 chars (3104 from context-load + 1719 from mode body)
[dryrun] No changes made.
```

**Dryrun with MiniMax profile:**
```
$ claude-profile --dryrun oreillyit-minimax --mode quick
[dryrun] Profile:         oreillyit-minimax (~/.claude-oreillyit-minimax)
[dryrun] Mode:            quick
[dryrun] Mode file:       ~/dev/claude/small-scripts/data/claude-profile/modes/quick.md
[dryrun] Driver:          sonnet
[dryrun] Model ID:        MiniMax-M2.7
[dryrun] Provider env:    ~/.claude-oreillyit-minimax/provider.env
[dryrun] Project:         <not set, will be picked by CLAUDE.md>
[dryrun] Async OK:        no
[dryrun] Autoloop:        none
[dryrun] Would execute:   claude --model MiniMax-M2.7 --append-system-prompt "<context+mode>"
[dryrun] No changes made.
```

In dryrun mode the interactive prompts are still shown, so the user can walk through the picker without committing.

## Edge cases

| Case | Handling |
|---|---|
| `~/dev/claude/small-scripts/data/claude-profile/modes/` does not exist | Error: "Mode files directory not found at <path>." Exit 1. |
| Mode file referenced by `--mode` does not exist | Error: "Mode file not found: <path>." Exit 1. |
| Mode file has malformed frontmatter (missing required field) | Error naming the missing field and the file path. Exit 1. |
| `provider.env` exists but has no `MODEL_ID` | Driver default is used; other entries are still exported. |
| `provider.env` specifies `ANTHROPIC_API_KEY_FILE` but the file does not exist | Error: "API key file not found: <path>." Exit 1. |
| `presets.yaml` does not exist and `--preset` was given | Error: "Preset '<name>' not found in any presets.yaml." Exit 1. |
| `presets.yaml` exists but the named preset is not in it | Error: "Preset '<name>' not found in any presets.yaml." Exit 1. |
| Preset's `profile` field references a non-existent profile | Error. Exit 1. |
| `--preset` and `--mode` both given | Error: "mutually exclusive". Exit 1. |
| Positional `PROFILE` and `--preset` profile field disagree | Error: "Profile mismatch: positional <X>, preset specifies <Y>." Exit 1. |
| `last-mode` file is missing or contains an unknown mode | Fall back to `quick` as the default. |
| Two parallel sessions launched against the same profile | Both write to the same `active-mode.env` — last writer wins. Documented limitation; not addressed in v1. |
| `CLAUDE_CONFIG_DIR` already set in the environment when claude-profile starts | Ignored; claude-profile sets it from the resolved profile, overriding whatever was inherited. |
| Mode file body is empty (frontmatter only) | Error: "Mode file has no body — nothing to load into the system prompt." Exit 1. |

## Out of scope (for v1)

- Multi-session coordination (parallel claude-profile launches against the same profile)
- Mid-session mode switching from inside Claude Code (handled by a separate `switch mode` skill; requires relaunching)
- Editing mode files in place (they are read-only data; customisation happens via `presets.yaml`)
- Network/remote profiles (everything is local)
- SOPS-encrypted provider credentials at launch time (credentials are stored as plaintext in `~/.claude-secrets/`; SOPS decryption is handled by the agent-runtimes container harness for headless agents)
- Pinning the model used by named custom subagents at the harness level (those are controlled by the subagent's own definition file; the Agent tool's per-call `model` parameter is unaffected)
