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 | $0.00013 | $0.00493 |
| Opus 5 | $0.00006 | $0.00246 |
| Sonnet 5 | $0.00003 | $0.00099 |
| Haiku 4.5 | $0.00001 | $0.00049 |
Grade A, and why
are-rebuild scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Reconstruct a project from specification documents using agents-reverse-engineer.
Steps
-
Read version: Read
.claude/ARE-VERSION→ store as$VERSION. Show the user:agents-reverse-engineer v$VERSION -
Run the rebuild command in the background using
run_in_background: true:npx agents-reverse-engineer@$VERSION rebuild --backend claude $ARGUMENTS -
Monitor progress by polling the latest progress log:
- Wait ~15 seconds (use
sleep 15in Bash), then use Glob to find the latest.agents-reverse-engineer/progress-*.logfile, and Read it (use theoffsetparameter to read only the last ~20 lines for long files) - Show the user a brief progress update (e.g. "4/12 rebuild units completed")
- Check whether the background task has completed using
TaskOutputwithblock: false - Repeat until the background task finishes
- Important: Keep polling even if no progress log exists yet (the command takes a few seconds to start writing)
- Wait ~15 seconds (use
-
On completion, read the full background task output and summarize:
- Number of rebuild units processed
- Files generated and output directory
- Any failures or partial completions
This reads spec files from specs/, partitions them into ordered rebuild units, and processes each via AI to generate source files.
Options:
--dry-run: Show rebuild plan without making AI calls--output <path>: Output directory (default: rebuild/)--force: Wipe output directory and start fresh--concurrency N: Control number of parallel AI calls (default: auto)--fail-fast: Stop on first failure--debug: Show AI prompts and backend details--trace: Enable concurrency tracing to.agents-reverse-engineer/traces/
Exit codes: 0 (success), 1 (partial failure), 2 (total failure)
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.

are-rebuild is a skill published in the GitHub repository GeoloeG-IsT/agents-reverse-engineer (20 stars, last pushed 1mo ago), licensed MIT. It adds 13 tokens to every session and 493 once invoked, about $0.0001 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 2026-08-30.
