/pbr:set-profile — Model Profile Manager

You are running the profile skill. Your job is to show the current model profile or switch to a new one by writing model assignments to .planning/config.json.

Reference: @references/model-profile-resolution.md for profile resolution logic and precedence rules.

Step 0 — Immediate Output

Before ANY tool calls, display this banner:

╔══════════════════════════════════════════════════════════════╗
║  PLAN-BUILD-RUN ► MODEL PROFILE                              ║
╚══════════════════════════════════════════════════════════════╝

Then proceed to Step 1.

Step 1 — Load Config

Read .planning/config.json.

If the file does not exist, output:

Error: .planning/config.json not found. Run /pbr:new-project first.

Stop immediately.

Step 2 — Parse Arguments

Extract the first word from $ARGUMENTS as the profile name. Trim whitespace.

• If $ARGUMENTS is empty or blank → show-mode (go to Step 3).
• If a profile name is present → switch-mode (go to Step 4).

Step 3 — Show Mode (no argument)

Display the current profile status and available options.

1. Read config.json key model_profile. If absent, treat as "balanced".
2. Read config.json key models (object). If absent, use empty object.
3. Read config.json key model_profiles (object, optional custom profiles). If absent, use empty object.

Output the following (fill in actual values):

Active profile: <model_profile value>

Current model assignments:
  researcher          : <models.researcher or "not set">
  planner             : <models.planner or "not set">
  executor            : <models.executor or "not set">
  verifier            : <models.verifier or "not set">
  integration_checker : <models.integration_checker or "not set">
  debugger            : <models.debugger or "not set">
  mapper              : <models.mapper or "not set">
  synthesizer         : <models.synthesizer or "not set">

Available presets:
  quality   — all agents use opus (maximum capability)
  balanced  — mix of sonnet/inherit/haiku (default)
  budget    — all agents use haiku (minimum cost)
  adaptive  — sonnet for planning/verification, inherit/haiku for execution

If model_profiles has any keys, also display:

Custom profiles:
  <profile-name>  — <key count> model overrides

Output: "Run /pbr:set-profile <name> to switch profiles."

Stop. Do not write anything.

Step 4 — Switch Mode (argument provided)

Step 4a — Validate Profile Name

Built-in preset names: quality, balanced, budget, adaptive.

Custom profile names: keys in config.json model_profiles (if any).

If the provided name does not match any of the above:

Error: Unknown profile "<name>".

Valid presets: quality, balanced, budget, adaptive
<list any custom profile names from config.json model_profiles, if any>

Run `/pbr:set-profile` to see the current status.

Stop immediately.

Step 4b — Resolve Model Values

Use the preset table to resolve model values:

Agent	quality	balanced	budget	adaptive
researcher	opus	sonnet	haiku	sonnet
planner	opus	inherit	haiku	sonnet
executor	opus	inherit	haiku	inherit
verifier	opus	sonnet	haiku	sonnet
integration_checker	sonnet	sonnet	haiku	haiku
debugger	opus	inherit	haiku	inherit
mapper	sonnet	sonnet	haiku	haiku
synthesizer	sonnet	haiku	haiku	haiku

For a custom profile (name found in config.json model_profiles):

• Start with the balanced defaults from the table above.
• Overlay any keys present in config.json model_profiles[<name>].
• Any agents not specified in the custom profile use the balanced default.

Step 4c — Write to config.json

Update config.json using the Bash tool with node -e inline script:

node -e "
const fs = require('fs');
const cfg = JSON.parse(fs.readFileSync('.planning/config.json', 'utf8'));
cfg.model_profile = '<name>';
cfg.models = cfg.models || {};
cfg.models.researcher = '<value>';
cfg.models.planner = '<value>';
cfg.models.executor = '<value>';
cfg.models.verifier = '<value>';
cfg.models.integration_checker = '<value>';
cfg.models.debugger = '<value>';
cfg.models.mapper = '<value>';
cfg.models.synthesizer = '<value>';
fs.writeFileSync('.planning/config.json', JSON.stringify(cfg, null, 2));
console.log('OK');
"

Replace each <value> with the resolved model string for that agent. Replace <name> with the profile name.

Step 4d — Confirm

Output:

Active profile set to: <name>

Model assignments updated:
  researcher          : <value>
  planner             : <value>
  executor            : <value>
  verifier            : <value>
  integration_checker : <value>
  debugger            : <value>
  mapper              : <value>
  synthesizer         : <value>

Config written to .planning/config.json.
Run /pbr:set-profile to verify.

Commit Changes

Reference: skills/shared/commit-planning-docs.md for the commit pattern.

If planning.commit_docs is true in config.json, commit config.json:

docs(profile): switch to {profile_name} model profile

Stop. Done.
