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 | $0.00000 | $0.02354 |
| Opus 5.5 | $0.00000 | $0.00942 |
| Sonnet 5.5 | $0.00000 | $0.00471 |
| Haiku 4.5 | $0.00000 | $0.00235 |
Grade A, and why
feature-develop-hermit 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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/feature-develop-hermit — Claude plans, Hermit implements
Same outline as /feature-develop, but the Phase 3 implementation
is delegated to Hermit over MCP so Claude's context never absorbs the
grunt-work tool output.
Claude is the orchestrator (interview, pattern search, plan, final verification). Hermit is the executor (TDD red-green implementation).
Arguments
$ARGUMENTS — PR number (or a short slug if you are not using GitHub PRs).
--strategy {aggressive|moderate|conservative}— delegation depth. If omitted, inferred from the model-strategy map in the checkpoint config (see "Checkpoint policy").--model <model_name>— which executor model Hermit should run with (e.g.--model glm-5.1,--model qwen3-coder:30b). If omitted, the gateway's default model is used.
Checkpoint policy
The delegation depth is read from:
$HERMIT_CHECKPOINT_CONFIG (env override)
├── ~/.claude/state/hermit-checkpoints.json (user-local)
└── scripts/harness/hermit-checkpoints.default.json (repo default)
Three strategies
| Strategy | Claude does | Hermit does |
|---|---|---|
aggressive |
interview · plan review · final verify | pattern search · plan doc · implementation |
moderate |
interview · pattern search · plan review · final verify | plan doc · implementation |
conservative |
interview · pattern search · plan doc · plan review · final verify | implementation only |
Auto-selection
If --strategy is absent, query the gateway's active model
(./bin/gateway.sh --status or GET /health → active_models[0]) and look
it up in the config's model_strategy_map:
- Prefix or substring match (e.g.
glm-5.1→glm→aggressive) - If nothing matches, fall back to
default_strategy.
Prerequisites
ghCLI authenticated (or skip the GitHub steps if you don't use it)- Hermit gateway + MCP server running (
./bin/gateway.sh --status) - Current branch is the PR branch, or the worktree already exists
Workflow
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.

feature-develop-hermit is a command published in the GitHub repository cafitac/hermit-agent (4 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,354 tokens. 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.
