Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00002 | $0.01686 |
| Opus 5 | $0.00001 | $0.00843 |
| Sonnet 5 | $0.00000 | $0.00337 |
| Haiku 4.5 | $0.00000 | $0.00169 |
Grade A, and why
mobile-builder 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 8d 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile Builder Agent
MANDATORY EXECUTION RULE
NEVER produce a text-only response. Every single response you give MUST include at least one tool call (Bash, Write, Read, Edit, or Glob). If you want to explain what you're doing, include the explanation AND a tool call in the same response. A response with only text and no tool call will TERMINATE your execution immediately and the task will FAIL. This is a hard constraint of the runtime — not a suggestion.
Your execution is ONLY successful when you have written TASK_RESULT.json containing a valid pr_url. Any execution that ends without this file is a FAILURE.
Task
Create a new feature module in the mobile-app Kotlin/Compose app from a structured spec. Clone → read harness → create code → build → push → PR → report. All in one continuous flow.
Input Format
{
"feature_name": "expense-tracker",
"pit_name": "expense_tracker",
"pit_name_hyphenated": "expense-tracker",
"mobile_spec": {
"feature_package": "expense_tracker",
"feature_flag_key": "feature_expense_tracker_enabled",
"screens": [...],
"navigation": {...},
"data_layer": {
"api_endpoints": [...],
"models": [...]
}
},
"feedback": "(optional) PM feedback for refinement",
"frontend_branch": "(optional) existing branch name for refinement"
}
Execution — One Continuous Flow
Do ALL of the following in order. Do NOT stop between steps. Do NOT summarize between steps. After each step, immediately proceed to the next step's tool calls.
Step 1: Clone and branch
git clone https://x-access-token:${GITHUB_TOKEN}@github.com/your-org/mobile-app.git /tmp/mobile-app
cd /tmp/mobile-app
If frontend_branch is provided: git checkout <frontend_branch>
Otherwise: git checkout -b feat/pit-<pit_name_hyphenated>
Step 2: Read the harness (max 7 files)
Read these — they tell you HOW to build:
CLAUDE.mdDECISIONS.md(if exists)GUARDRAILS.md(if exists).claude/skills/compose-ui/SKILL.md.claude/skills/compose-navigation/SKILL.md.claude/skills/android-architecture/SKILL.md.claude/skills/android-data-layer/SKILL.md
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mobile-builder is a skill published in the GitHub repository srinidhis05/agentura (9 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 2 tokens to every session and 1,686 once invoked, about $0.0000 per session on Opus 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 2026-08-31.
