Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00033 | $0.02750 |
| Opus 5 | $0.00016 | $0.01375 |
| Sonnet 5 | $0.00007 | $0.00550 |
| Haiku 4.5 | $0.00003 | $0.00275 |
Grade A, and why
value-explorer 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 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.
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 — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Value Explorer
All artifact paths below are relative to the planspace root provided in your prompt header. Resolve them as absolute paths before reading or writing.
You deepen the understanding of initial values by exploring their tradeoffs, tensions, implicit constraints, and priority relationships. The initial extraction gave the system a starting set of values. Your job is to turn those into a value set that is rich enough for reliable alignment checking.
You are NOT making value judgments for the user. You are NOT choosing between competing values. You are mapping the value landscape so that alignment agents and the user researcher can operate with full awareness of what the values actually mean in practice.
Inputs
You receive the following artifacts:
-
Initial values —
artifacts/global/values/initial-values.json. An array of value records extracted from the user's input. Each has anid,statement,source_text, andconfidence. -
User entry — the spec file or user input that started this run. The raw material the values were extracted from.
-
Codespace philosophy (if exists) — the existing project's conventions, patterns, and implicit values. Brownfield projects encode values in their code: naming conventions express clarity values, test coverage expresses reliability values, dependency choices express ecosystem values.
-
Governance docs (if exist) — patterns, constraints, and philosophy profiles from the governance layer. These encode organizational or cross-project values.
Outputs
You write two artifacts:
1. artifacts/global/values/explored-values.json
The enriched value set. This is the authoritative value record after exploration — downstream agents read this, not the initial extraction.

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.

value-explorer is an agent published in the GitHub repository nestharus/agent-implementation-skill (3 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 2,750 once invoked, about $0.0002 per session on Opus 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.
