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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00041 | $0.00991 |
| Opus 5.5 | $0.00016 | $0.00396 |
| Sonnet 5.5 | $0.00008 | $0.00198 |
| Haiku 4.5 | $0.00004 | $0.00099 |
Grade A, and why
validate 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/validate
Run full validation on the current finding before writing a report.
What This Does
- Runs 7-Question Gate (one wrong answer = kill it)
- Checks against the always-rejected list
- Runs 4 pre-submission gates
- Outputs: PASS (write the report) or KILL (move on)
Usage
/validate
Describe the finding when prompted. Include:
- The endpoint
- The bug class
- What the PoC shows
- The target program
The 7-Question Gate
Answer each. ONE wrong answer = STOP.
Q1: Can I demonstrate this step-by-step RIGHT NOW?
Write this out:
1. Setup: I need [own account / another user's ID / no account]
2. Request: [exact HTTP method, URL, headers, body]
3. Result: Response shows [exact data / action completed]
4. Impact: Real consequence is [account takeover / PII exposed / money stolen]
5. Cost: Time: [X min], Capital: [$0 / $X]
If step 2 is "I need to look at the code more" → KILL IT.
Q2: Is the impact accepted by this program?
Check program scope page. Is your bug class listed? Is it excluded?
Q3: Is the vulnerable asset in scope?
Exact domain in scope? Not staging/dev? Not a third-party service?
Q4: Does it need admin or privileged access that an attacker can't get?
"Admin can do X" → KILL IT. "Regular user can do X that only admin should" → valid.
Q5: Is this known or documented behavior?
Search disclosed reports + changelog + API docs.
Q6: Can you prove impact beyond "technically possible"?
- XSS → actual cookie value in exfil request, not just alert()
- SSRF → response body from internal service, not just DNS callback
- IDOR → actual other-user's private data in response, not just 200 status
Q7: Is this on the never-submit list?
Missing headers, GraphQL introspection alone, clickjacking without PoC,
self-XSS, open redirect alone, SSRF DNS-only, logout CSRF, banner disclosure,
rate limit on non-critical forms, missing cookie flags alone...
If yes → KILL IT unless you have a chain.
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.

validate is a command published in the GitHub repository elementalsouls/Claude-BugHunter (4,874 stars, last pushed 6d ago), licensed MIT. It adds 41 tokens to every session and 991 once invoked, about $0.0002 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.
