SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 73 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
- medium Rogue Agent · line 77 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 | $0.00074 | $0.01360 |
| Opus 5 | $0.00037 | $0.00680 |
| Sonnet 5 | $0.00015 | $0.00272 |
| Haiku 4.5 | $0.00007 | $0.00136 |
Grade A, and why
e2e-runs 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

E2E runs, run diagnostics, and the dashboard's Playwright suite
Moved out of
CLAUDE.mdon 2026-08-22 so it loads when it is needed rather than in every session. Nothing was cut — the text below is those three sections verbatim.
Consumer Project Diagnostics
set-core is developed and battle-tested through consumer projects. Before fixing bugs or adding features, always consult the primary consumer for real-world diagnostics.
Harvest (primary tool)
After every E2E run, use set-harvest to scan consumer projects for framework-relevant fixes:
set-harvest # scan all registered consumer projects
set-harvest --project craftbrew-run-20260320-1445 # scan single project
set-harvest --dry-run # preview without updating state
The harvest tool scans ISS fix commits, classifies them (framework-relevant vs project-specific), and presents them for interactive adoption into planning rules, templates, or core code.
Manual workflow
- Read the latest orchestration run log — each log has a "set-core Bugs to Report" section and "Conclusions for set-core Development" with prioritized issues, root cause analysis, and design decisions.
- Diff .claude/ for upstream changes — during orchestration, the sentinel or user may improve commands, skills, or configs in the consumer's
.claude/. Diff against set-core source to find changes to adopt. - Check orchestration.yaml — the consumer's config reflects production usage. Understand what directives are actually used before changing defaults.
- Use run comparison data — run logs contain quantitative comparisons (wasted iterations, token efficiency, intervention count). Use these to validate whether a fix actually improved things.

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.

e2e-runs is a skill published in the GitHub repository tatargabor/set-core (35 stars, last pushed 2d ago), licensed MIT. It adds 74 tokens to every session and 1,360 once invoked, about $0.0004 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 2026-09-06.
