Getting it into your agent

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 | $0.00485 |
| Opus 5 | $0.00000 | $0.00243 |
| Sonnet 5 | $0.00000 | $0.00097 |
| Haiku 4.5 | $0.00000 | $0.00049 |
Grade C, and why
readonly scanned grade C with 1 finding 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 8d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- This is a **workflow guard** ("don't touch"), not a security sandbox — precise for the editor tools, best-effort for Bash. The always-on safety hooks (`rm -rf`, force-push, credential leaks) are the real floor and stay Copies of this mod

What it actually says
Read-only mode — "look, don't touch" for a while. Arguments: $ARGUMENTS ( [session|global] | off | status)
The inverse of /sc-autopilot: while read-only mode is on, Supercharger blocks every file edit (Write/Edit/MultiEdit/NotebookEdit) and every mutating shell command (rm, mv, git commit/push, npm install, sed -i, redirects that write a file, …). Reads, searches, and planning stay allowed. Great for exploring or reviewing a codebase without any risk of accidental changes. It auto-expires and is hard-capped at 2 hours.
Scope (default is per-session):
session(default) — only this Claude session is read-only.global— every session on the machine is read-only.
Run it (pass the argument straight through; default to status if none given):
bash ${CLAUDE_PLUGIN_ROOT}/tools/readonly.sh $ARGUMENTS
Then report the tool's output verbatim.
/sc-readonly 20m— read-only for 20 minutes in this session only. Accepts20m,2h,90s, or a bare number (minutes)./sc-readonly 20m global— read-only for all sessions on the machine./sc-readonly off— turn it off now; edits are allowed again./sc-readonly status— show whether it's on (per-session and/or global) and how long is left.
Notes to surface to the user:
- This is a workflow guard ("don't touch"), not a security sandbox — precise for the editor tools, best-effort for Bash. The always-on safety hooks (
rm -rf, force-push, credential leaks) are the real floor and stay active either way. - It ends automatically at the deadline (checked on each tool call — no background timer). The statusline shows a
⚡ Read-only: Nm leftindicator while it's active. - Interacts cleanly with autopilot: read-only wins — a blocked edit is blocked even if autopilot would have auto-approved it (tighten beats loosen).
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.

readonly is a command published in the GitHub repository smrafiz/claude-supercharger (11 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 485 tokens. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
