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 | $0.08739 | $0.08739 |
| Opus 5.5 | $0.03496 | $0.03496 |
| Sonnet 5.5 | $0.01748 | $0.01748 |
| Haiku 4.5 | $0.00874 | $0.00874 |
Grade C, and why
agentic_coding_lab CLAUDE.md scanned grade C with 3 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 11d 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.

Agentic Coding Lab
Research framework for studying how TDD workflow structures and prompt styles affect AI-generated code quality. Runs Claude Code CLI in Docker containers against coding katas, then analyzes results via RQ-driven aggregation.
Full documentation: README.md — methodology, RQ frontmatter schema, workflow descriptions, model configurations, script reference, metrics glossary.
Skills
/run-rq RQ-N
End-to-end RQ orchestration: validate README → generate fill plan → start Docker batch → monitor progress → aggregate → propose findings updates. Pure orchestration calling existing repo scripts.
- Triggers: "run-rq", "fill RQ-N", "RQ-N voranbringen", "Forschungsfrage N starten"
- Details:
.claude/skills/run-rq/SKILL.md
/reanalyze RQ-N
Re-run analysis pipeline on all runs matching an RQ, reaggregate metrics, and propose findings updates. No new runs — only refreshes existing data after pipeline changes.
- Triggers: "reanalyze RQ-N", "reanalyse", "Runs neu analysieren"
- Details:
.claude/skills/reanalyze/SKILL.md
/build-overview
Generates a frozen experiment-overview snapshot across all RQs under research/reports/. Runs generate-snapshot-skeleton.py, then fills synthesis sections from findings.md files.
- Details:
.claude/skills/build-overview/SKILL.md
/publish-site
Builds the results site and publishes it to the gh-pages branch. Checks the
preconditions deploy-site.py enforces before spending a build on them, sorts the
research/ diff a build produces into substantive changes and one-time float churn, and
deploys only on explicit request — the push is public.
- Triggers: "publish", "deploy", "site deployen", "gh-pages", "auf die Seite bringen"
- Details:
.claude/skills/publish-site/SKILL.md - Not the same as
/build-overview: that writes a frozen Markdown snapshot underresearch/reports/, this publishes the live site. Both get called "published".
/exact-coding-baseline-export [line] [date] [source-workflow]
Mint a dated consumer snapshot under research/workflow-dev/export/ for either promoted EXACT Coding line. opus (default for backward compatibility) resolves the correctness-oriented Hybrid source from workflow-construction.md; sol resolves the Predictive-TDD source from model-recommendation-matrix.md and runs export-sol.py. Both remove lab content, restore HITL, and gate invocation. The SOL path emits Claude Code, pi, OpenCode, Cursor and Copilot ports and can explicitly synchronize local sol/* branches in EXACT-Coding with --sync-distribution; it never pushes.
- Triggers: "exact-coding baseline export", "neue exact-coding baseline", "exact-coding-baseline-export"

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.

agentic_coding_lab CLAUDE.md is an instructions file published in the GitHub repository marcoemrich/agentic_coding_lab (30 stars, last pushed 5d ago), licensed MIT. It adds 8,739 tokens to every session, about $0.0350 per session on Opus 5.5. A static security scan graded it C with 3 findings (downloads and executes remote code, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
