An agent that validates movement between DEV, TEST, and REVIEW phases in a GitHub Elements workflow. It checks that the required conditions are met and blocks invalid moves.

Use it before changing a work item's phase or when checking whether a transition is allowed.

It prevents work from skipping required stages or advancing before its prerequisites are complete.

Token cost

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	$0.00132	$0.07378
Opus 5.5	$0.00053	$0.02951
Sonnet 5.5	$0.00026	$0.01476
Haiku 4.5	$0.00013	$0.00738

Security

Grade A, and why

phase-gate 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.

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 transition policies:

enabled: If false, allow all transitions (bypass mode)
enforcement_level:
- strict: All criteria must be met, no exceptions
- standard: All criteria required, but allow override with reason
- lenient: Advisory only, always allow with warning

Defaults if no settings file: enabled=true, enforcement_level=standard

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.

It adds 132 tokens to every session and 7,378 once invoked, about $0.0005 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 2026-08-31.

Git and workflow

plastic-node-work

Dispatched for a work node by Plastic's node-graph runner. Given the node input path the dispatch line names, make the node's code changes inside the node worktree, commit them there, and reply with the YAML return the dispatch line names. Never spawned outside a runner dispatch.
