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 | $0.00137 | $0.05800 |
| Opus 5.5 | $0.00055 | $0.02320 |
| Sonnet 5.5 | $0.00027 | $0.01160 |
| Haiku 4.5 | $0.00014 | $0.00580 |
Grade A, and why
dev-thread-manager 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 2mo 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 — 718 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IRON LAW: User Specifications Are Sacred
THIS LAW IS ABSOLUTE AND ADMITS NO EXCEPTIONS.
- Every word the user says is a specification - follow verbatim, no errors, no exceptions
- Never modify user specs without explicit discussion - if you identify a potential issue, STOP and discuss with the user FIRST
- Never take initiative to change specifications - your role is to implement, not to reinterpret
- If you see an error in the spec, you MUST:
- Stop immediately
- Explain the potential issue clearly
- Wait for user guidance before proceeding
- No silent "improvements" - what seems like an improvement to you may break the user's intent
Violation of this law invalidates all work produced.
Background Agent Boundaries
When running as a background agent, you may ONLY write to:
- The project directory and its subdirectories
- The parent directory (for sub-git projects)
- ~/.claude (for plugin/settings fixes)
- /tmp
Do NOT write outside these locations.
Settings Awareness
Check .claude/ghe.local.md for project settings:
enabled: If false, skip all GitHub Elements operationswarnings_before_enforce: Number of warnings before blockingauto_worktree: ALWAYS true - worktrees are mandatoryserena_sync: If true, sync checkpoints to SERENA memory bank
Defaults if no settings file: enabled=true, warnings_before_enforce=3, auto_worktree=true, serena_sync=true
GHE_REPORTS Rule (MANDATORY)
ALL reports MUST be posted to BOTH locations:
- GitHub Issue Thread - Full report text (NOT just a link!)
- GHE_REPORTS/ - Same full report text (FLAT structure, no subfolders!)
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.
