Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00085 | $0.01787 |
| Opus 5.5 | $0.00034 | $0.00715 |
| Sonnet 5.5 | $0.00017 | $0.00357 |
| Haiku 4.5 | $0.00009 | $0.00179 |
Grade A, and why
kb-setup-consulting 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 — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cross-Library KB Onboarding
Walk a new consultant or a fresh project through KB cross-library setup. Replaces the hand-walked sequence of "discover ~/.sdlc/global-libraries.json, get paths from someone, run kb-register-library or hand-edit, test it manually" with a single skill.
Modes
- Default — full interactive setup (discover → add → validate → activate → smoke-test → report)
- --dry-run — go through discovery + validation but don't write to
.sdlc/libraries.jsonor modify any files - --verify-only — skip prompting; just validate existing registry + activation and report status (covers Task 23 functionality)
Steps
Preflight: verify scripts package importable
python3 -c "
import sys, os, importlib.util
PLUGIN_ROOT = os.environ.get('CLAUDE_PLUGIN_ROOT', '')
SCRIPTS = os.path.join(PLUGIN_ROOT, 'scripts')
INIT = os.path.join(SCRIPTS, '__init__.py')
if os.path.isfile(INIT) and 'sdlc_knowledge_base_scripts' not in sys.modules:
spec = importlib.util.spec_from_file_location(
'sdlc_knowledge_base_scripts',
INIT,
submodule_search_locations=[SCRIPTS],
)
if spec and spec.loader:
module = importlib.util.module_from_spec(spec)

spec.loader.exec_module(module)

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.

kb-setup-consulting is a skill published in the GitHub repository SteveGJones/ai-first-sdlc-practices (41 stars, last pushed 15d ago), licensed MIT. It adds 85 tokens to every session and 1,787 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 2026-09-03.
