Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00028 | $0.01408 |
| Opus 5.5 | $0.00011 | $0.00563 |
| Sonnet 5.5 | $0.00006 | $0.00282 |
| Haiku 4.5 | $0.00003 | $0.00141 |
Grade A, and why
profile scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
STOP — DO NOT READ THIS FILE. You are already reading it. This prompt was injected into your context by Claude Code's plugin system. Begin executing Step 0 immediately.
/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
$ARGUMENTSis 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.
- Read
config.jsonkeymodel_profile. If absent, treat as"balanced". - Read
config.jsonkeymodels(object). If absent, use empty object. - Read
config.jsonkeymodel_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
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

profile is a skill published in the GitHub repository SienkLogic/plan-build-run (19 stars, last pushed 6mo ago), licensed MIT. It adds 28 tokens to every session and 1,408 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
