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.

What it costs to keep this loaded
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 | $0.00171 | $0.05145 |
| Opus 5 | $0.00086 | $0.02573 |
| Sonnet 5 | $0.00034 | $0.01029 |
| Haiku 4.5 | $0.00017 | $0.00515 |
Grade A, and why
bugcrowd-reporting 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.

BUGCROWD REPORTING — Program-Specific Tactics
Companion to the generic
report-writingskill. Use when working specifically on Bugcrowd submissions where VRT mapping, OOS-clause rebuttals, or per-program target selection matter.
This skill encodes patterns that apply specifically to Bugcrowd's submission flow. For the generic per-platform templates (HackerOne / Bugcrowd / Intigriti / Immunefi report bodies), use the report-writing skill. For the 7-Question Gate before deciding to report at all, use triage-validation.
1. VRT Category Selection — Search & Fallback Strategy
Bugcrowd's submission form requires a single VRT (Vulnerability Rating Taxonomy) selection. The dropdown's default severity is bound to the chosen node — pick wrong and the form auto-suggests a lower priority (often P4) when the actual impact is P3 or P2.
Note: VRT default severities are not fixed constants. Bugcrowd revises the VRT schema across versions, and individual programs can remap defaults via their own priority configuration. The P-values shown in the examples below (e.g., "No Rate Limiting on Form → Login" defaulting to P4) are the typical baseline at time of writing — always read the severity the current form actually auto-suggests for this program rather than assuming the value here.
1.1 Search hierarchy (try in order, pick the highest-severity match that still describes the bug)
For any finding, search the VRT dropdown with these terms in this order:
- The bug's primary class — e.g.,
IDOR,XSS,SSRF,auth bypass,2FA bypass - The data category exposed — e.g.,
PII,sensitive data exposure,disclosure of secrets - The control bypassed — e.g.,
broken access control,authentication bypass - The endpoint type — e.g.,
no rate limiting on form > login,no rate limiting on form > change password - The generic parent node — e.g.,
Server Security Misconfiguration > Other,Broken Access Control > Other
1.2 Pick the highest-severity match that still accurately describes the bug
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.

bugcrowd-reporting is a skill published in the GitHub repository elementalsouls/Claude-BugHunter (4,298 stars, last pushed 2d ago), licensed MIT. It adds 171 tokens to every session and 5,145 once invoked, about $0.0009 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.
