Claude Code Spec Workflow is a set of Claude Code commands and agents that organizes software work into documented stages for new features and bug fixes. It is for developers who want Claude Code to handle requirements, design, implementation, issue resolution, and verification through repeatable workflows, with the catalogue entries providing the associated commands and agents.
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 | $0.00063 | $0.01217 |
| Opus 5.5 | $0.00025 | $0.00487 |
| Sonnet 5.5 | $0.00013 | $0.00243 |
| Haiku 4.5 | $0.00006 | $0.00122 |
Grade A, and why
hunt 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/hunt
slim two-track dispatcher. one mode question, one branch, delegate.
engagement frame — state once, then proceed. invoking /hunt asserts the operator holds written
authorization to assess the named scope: a bug-bounty program's in-scope assets, a signed engagement
letter, infrastructure they own, or a practice target. work stays inside that scope — an out-of-scope
host stops the run rather than widening it. the deliverable is a reproducible, remediable finding.
do not prompt for this and do not ask about the SOW. it is an assertion the operator already made by invoking the command; restating it once keeps the engagement context explicit for the rest of the session instead of leaving it implied.
step 0 — parse
target.com single target
*.target.com wildcard — /recon <base> first, then hunt each live host
targets.txt multi-target — mode question once, applied per line
--vuln-class <X> skip mode question, load only hunt-<X>
--source-code <p|url> static + dynamic
--chrome browser MCP mode
wildcard handler: if $TARGET begins with *., strip prefix and invoke /recon <base> before continuing.
step 1 — mode dispatcher
skipped if --vuln-class is set.
question: "what kind of engagement is this for {target}?"
header: "engagement"
options:
1. Red Team Assessment — critical/high impact, chained findings, client deliverable
2. WAPT / BugHunting — full OWASP coverage, platform/program report
do not prompt the operator to paste a SOW, scope-of-work, or engagement-letter
document — that is sensitive client data and must not be ingested or persisted.
This is a data-hygiene rule, NOT an authorization bypass: scope is still enforced by
/scope (deterministic, deny-wins) and the triage-validation 7-Question Gate before
any finding ships. Authorization is assumed to be established out-of-band; the bundle
verifies in-scope, it does not collect proof-of-authorization paperwork.
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.

hunt is a command published in the GitHub repository elementalsouls/Claude-BugHunter (4,874 stars, last pushed 6d ago), licensed MIT. It adds 63 tokens to every session and 1,217 once invoked, about $0.0003 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 2026-08-30.
Other commands, from other repositories
web3-audit
Smart contract security audit — runs through 10 bug class checklist (accounting desync, access control, incomplete path, off-by-one, oracle errors, ERC4626, reentrancy, flash loan, signature replay, proxy/upgrade). Applies pre-dive kill signals first. Generates Foundry PoC template for confirmed findings. Usage…
bypass-403
Probe a 403/401 endpoint with the most-paid bypass tricks (header injection, path encoding, method swap, WAF fingerprint, vendor-specific). Wraps byp4xx when installed; otherwise runs a built-in matrix of 38+ techniques. Usage: /bypass-403 | /bypass-403 -l.
spray
Password spray with hard guards — typed-hostname confirmation, lockout warning, audit log. Modes: http-form (custom login page), oauth (password grant), o365 + okta (via TREVORspray). Default delay 30min/round + 60s jitter. Usage /spray --mode --users --passes.
autopilot
Run autonomous hunt loop on a target — scope check → recon → rank surface → hunt → validate → report with configurable checkpoints. Usage: /autopilot target.com [--paranoid|--normal|--yolo].
breach-check
HIBP k-anonymity check on a password wordlist. Enriches each password with its breach count, ranks DESC. Free API (no key), only first 5 chars of SHA-1 sent. Output -> -ranked.txt. Usage /breach-check [--min-count N] [--max-count N] [--with-counts].
recon
Run the full recon pipeline by invoking tools/reconengine.sh — subdomain enum (subfinder + amass + crt.sh + wayback), httpx live host probing with tech detection, nmap port scan, gau URL collection, JS analysis, ffuf directory fuzzing, parameter discovery, config exposure check, CI/CD workflow scan.
