Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00024 | $0.00680 |
| Opus 5 | $0.00012 | $0.00340 |
| Sonnet 5 | $0.00005 | $0.00136 |
| Haiku 4.5 | $0.00002 | $0.00068 |
Grade A, and why
local-env 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 7d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prove Local Env
Write this machine's claude-prove checkout path into the env block of .claude/settings.local.json (auto-gitignored, injected by Claude Code into hooks and Bash), and refresh the reference symlink chain .claude/prove-plugin → ~/.claude-prove/latest → checkout.
Why: git-tracked artifacts carry no machine paths — hook commands and CLAUDE.md command examples reference ${CLAUDE_PROVE_PLUGIN_DIR:-$HOME/.claude/plugins/prove} (the env block supplies the value), and CLAUDE.md @-references load through the symlink chain (the links supply the path). Each machine sets both here in one step.
Step 1: Detect the checkout
Resolve the plugin checkout directory, first match wins:
$CLAUDE_PLUGIN_ROOTif set and it containspackages/cli/bin/run.ts$(pwd)if it contains both.claude-plugin/plugin.jsonandpackages/cli/bin/run.ts(you are inside the claude-prove repo itself)- Otherwise ask the user free-form: "Where is your claude-prove checkout?"
Validate the candidate contains packages/cli/bin/run.ts. If not, report the path and ask again — do not write anything.
Step 2: Confirm
AskUserQuestion with header "Local env":
- question: "Write
CLAUDE_PROVE_PLUGIN_DIR=<resolved path>into.claude/settings.local.json? This file is local to this machine and gitignored." - "Write it" — proceed
- "Change path" — ask free-form for the correct checkout path, re-validate, re-confirm
Step 3: Write
claude-prove install local-env --plugin-dir "<resolved path>"
On failure, surface the CLI error verbatim and stop.
Step 4: Verify and repair drift
Run claude-prove install doctor and inspect the three related checks:
plugin-dir-env— must PASS now (sourceprocess-envorsettings.local.json)stable-root— must PASS when CLAUDE.md carries@.claude/prove-plugin/...references (the symlink chain resolves)hook-paths[...]— a WARN mentioning "machine-absolute dev prefix" means.claude/settings.jsonstill carries the pre-portable format
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.

local-env is a command published in the GitHub repository mjmorales/claude-prove (2 stars, last pushed 28d ago), licensed MIT. It adds 24 tokens to every session and 680 once invoked, about $0.0001 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.
