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 | $0.00145 | $0.04667 |
| Opus 5 | $0.00072 | $0.02334 |
| Sonnet 5 | $0.00029 | $0.00933 |
| Haiku 4.5 | $0.00015 | $0.00467 |
Grade A, and why
apk-redteam-pipeline scanned grade A with 1 finding 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 12d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -sk -A "Mozilla/5.0" "https://play.google.com/store/apps/developer?id=<Brand+Name>" -o /tmp/dev.html Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 408 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use this skill
Trigger when:
- Recon surfaces 1+ mobile apps under the target's developer name (Play Store dev page)
- A web app hosts
*.apkfiles directly (e.g.Recruitz.apkfound on a subdomain during one engagement) - APK package IDs leaked via stealer logs (e.g.
com.<brand>.app,com.<brand>.<sub-brand>patterns in stealer dump format) - Customer-facing app, dealer/partner portal, or employee mobile companion app is in scope
- Bug bounty program lists Android in scope
DO NOT use for:
- iOS-only targets (different pipeline — IPA reverse, MobSF, frida-ios-dump)
- React Native / Flutter web apps already covered by JS bundle analysis
- Server-side only assessments
Stage 0 — Inventory all org-owned apps
Play Store developer-page scrape
# Find developer page from the target's brand name
curl -sk -A "Mozilla/5.0" "https://play.google.com/store/apps/developer?id=<Brand+Name>" -o /tmp/dev.html
# Extract package IDs
grep -oE 'id=[a-zA-Z0-9._]+' /tmp/dev.html | sort -u
Example output (anonymized — 7 packages typical for a multi-brand conglomerate):
com.events.<brand>build
com.<corp>.<sub-brand-1>
com.<corp>.<sub-brand-2>
com.<corp>.<flagship>
com.<corp>.<product-line-1>
com.<corp>.<product-line-2>
com.<corp>.<sub-brand-3>
Cross-reference with stealer logs
Stealer-log format includes package names like *@com.<corp>.<app> — extract these from creds_userpass.txt if you have a leaked dump.
Brand permutation guesses (multi-brand conglomerate patterns)
com.<brand>.app
com.<brand>.mobile
com.<brand>.android
com.<brand>connect.app
in.<brand>.dealer
in.co.<brand>.app
Stage 1 — APK acquisition
Primary: APKPure direct (no auth required)
# Follow 302 redirects to actual download
curl -sk -L --max-time 60 \
"https://d.apkpure.net/b/APK/<package_id>?version=latest" \
-o "<package_id>.apk"
# Or via the legacy d-XX.winudf.com mirror chain (we saw this work)
Secondary: APKMirror search
curl -sk -A "Mozilla/5.0" "https://www.apkmirror.com/?post_type=app_release&searchtype=apk&s=<brand>" \
| grep -oE 'href="[^"]+\.apk[^"]*"' | sort -u
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.

apk-redteam-pipeline is a skill published in the GitHub repository elementalsouls/Claude-BugHunter (4,298 stars, last pushed 6d ago), licensed MIT. It adds 145 tokens to every session and 4,667 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
