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 | $0.00034 | $0.00745 |
| Opus 5.5 | $0.00014 | $0.00298 |
| Sonnet 5.5 | $0.00007 | $0.00149 |
| Haiku 4.5 | $0.00003 | $0.00075 |
Grade A, and why
zeus-discover 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 1mo 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.

Zeus Discover - Brownfield Codebase Mapper
Use this skill to analyze an existing project and generate reusable codebase context before planning and execution.
Preconditions
.zeus/{version}/exists (defaultmain).- You can write to
.zeus/{version}/. - The target project root is readable.
Inputs
--project-root <path>(optional, default current workspace root)--depth quick|auto|full(optional, defaultauto)--version vN(optional, defaultmain)
Security rules
- Never read or print secret values from
.env*,*secret*,*credential*, key/cert files. - For sensitive files, only record existence and path.
- Output must contain no credentials or token-like strings.
Deterministic workflow
1) Resolve scope
Resolve version folder and project root:
- output base:
.zeus/{version}/ - map target:
{project-root}
2) Collect structural inventory
Collect and summarize:
- top-level directories and key entry points,
- package/runtime manifests,
- test config and test file patterns,
- major module directories and size hotspots,
- TODO/FIXME/HACK markers.
3) Collect dependency and integration signals
Extract from manifests and imports:
- language/runtime/framework set,
- critical dependencies and tooling,
- external integration candidates (SDK/API clients),
- datastore/auth/observability hints when present.
4) Build module map
Generate module-level records with:
- path,
- role classification (
api,frontend,infra,data,shared,test,unknown), - approximate LOC,
- key dependency links,
- risk markers (
large-file,todo-density,high-fan-in).
5) Write brownfield artifacts
Write these files to .zeus/{version}/:
codebase-map.jsonexisting-modules.jsontech-inventory.mdarchitecture.md
6) Validate and summarize
- Validate JSON structure against schemas when available.
- If schema file is missing, continue and note validation skipped.
- Return concise summary with artifact paths and record counts.
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.

zeus-discover is a skill published in the GitHub repository huifer/zeus (22 stars, last pushed 6mo ago), licensed MIT. It adds 34 tokens to every session and 745 once invoked, about $0.0001 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 2026-08-30.
