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 | $0.00118 | $0.01400 |
| Opus 5 | $0.00059 | $0.00700 |
| Sonnet 5 | $0.00024 | $0.00280 |
| Haiku 4.5 | $0.00012 | $0.00140 |
Grade A, and why
mode 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 5d 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.
This is a copy
100% identical to mode — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/mode — operational overlays on the taste corpus
Identity is centralized in .rockie/taste/. Modes carry the small,
context-dependent policy bits that flip between sessions:
paper-deadline vs. exploratory vs. dogfooding vs. teaching.
A mode is a TOML file at .rockie/taste/modes/<name>.toml. The
active mode is named in .rockie/taste/modes/_active (one line).
SessionStart loads it and surfaces a compact summary alongside the
researcher identity from INDEX.md.
When to use
- A new context (deadline, area, register) where overrides apply.
- The harness behavior shouldn't change who you are, just what you optimize for this session.
Subcommands
python3 .agents/skills/mode/runtime/mode.py show # active mode + diff vs central
python3 .agents/skills/mode/runtime/mode.py list # available modes
python3 .agents/skills/mode/runtime/mode.py switch <name> # atomic flip _active
python3 .agents/skills/mode/runtime/mode.py new <name> [--from <template>]
python3 .agents/skills/mode/runtime/mode.py edit <name> # opens in $EDITOR
python3 .agents/skills/mode/runtime/mode.py diff <a> <b> # compare two modes
python3 .agents/skills/mode/runtime/mode.py active # print just the active name
Built-in templates
Shipped in <rockie>/project-harness/skills/mode/templates/. The
installer copies them into .rockie/taste/modes/ on first run if
that directory doesn't exist yet.
| Template | When |
|---|---|
default |
No overrides — central corpus is canonical |
paper-crunch |
Deadline-locked: scope_lock, formal register, smoke gates, Opus on attack/review |
exploratory |
No scope lock, broad reading window, sonnet-first, register=lab-notebook |
dogfooding |
Harness self-modification or first-run testing — tight budgets, fast cycles |
learning |
Educational sessions: register=teaching, gates relaxed, Opus on explanations |

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 5d ago First seen · 145 lines · 118 tokens per session scan A 2a718f0aa58f
mode is a skill published in the GitHub repository Rockielab/rockie-codex (20 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 118 tokens to every session and 1,400 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to mode, differing in 16 lines, and is treated as a copy.
