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 | $0.00015 | $0.00991 |
| Opus 5 | $0.00008 | $0.00495 |
| Sonnet 5 | $0.00003 | $0.00198 |
| Haiku 4.5 | $0.00002 | $0.00099 |
Grade A, and why
audit 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 5d 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.

ESBMC Security Audit Command
Perform a comprehensive security audit using multiple ESBMC verification passes run concurrently.
Instructions
-
Check that ESBMC is installed by running
which esbmc. If not found, stop and tell the user:- Download pre-built binaries from https://github.com/esbmc/esbmc/releases
- Or build from source: https://github.com/esbmc/esbmc
- Ensure
esbmcis in the PATH:export PATH=$PATH:/path/to/esbmc/bin
-
Read the source file to understand its structure and detect:
- Language (C, C++, Python, Solidity)
- Presence of concurrency (pthreads, std::thread, threading module)
- Complexity indicators (loops, recursion, dynamic allocation)
-
Solver detection — run
esbmc --list-solversand select the best available solver using this priority order: Boolector → Bitwuzla → Z3. Use the corresponding flag:--boolector,--bitwuzla, or--z3. Store this as<solver-flag>. If none of these solvers are listed as available, stop and tell the user that ESBMC is built without solver support, and direct them to build ESBMC with solver support: https://github.com/esbmc/esbmc -
Loop discovery — run
esbmc <file> --show-loopsto list all loops. Choose the unwind strategy:- No loops found → no unwind flag needed
- Loops with bounds apparent from the source → use
--unwindset L1:N,...with per-loop bounds derived from the source - Loops with unknown or dynamic bounds → use
--incremental-bmc
Store the resulting unwind flag(s) as
<unwind-strategy>. -
Spawn parallel subagents using the Task tool (subagent_type: general-purpose), one per pass. Launch all subagents in a single message so they execute concurrently. Each subagent receives: the file path,
<solver-flag>,<unwind-strategy>, and its specific checks.Subagent Checks Command A: Default properties (none — covers bounds, ptr safety, div-by-zero) esbmc <file> <solver-flag> <unwind-strategy> --timeout 60sB: Memory safety --memory-leak-checkesbmc <file> <solver-flag> <unwind-strategy> --memory-leak-check --timeout 60sC: Integer safety --overflow-check --unsigned-overflow-checkesbmc <file> <solver-flag> <unwind-strategy> --overflow-check --unsigned-overflow-check --timeout 60sD: UB shifts --ub-shift-checkesbmc <file> <solver-flag> <unwind-strategy> --ub-shift-check --timeout 60sE: Concurrency (only if threads detected in step 2) --deadlock-check --data-races-check --context-bound 2esbmc <file> <solver-flag> <unwind-strategy> --deadlock-check --data-races-check --context-bound 2 --timeout 60s
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.

audit is a command published in the GitHub repository esbmc/agent-marketplace (4 stars, last pushed 6mo ago), licensed MIT. It adds 15 tokens to every session and 991 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 2026-08-31.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
