Summary

Three small follow-ups now that the Internet Computer connector is published in Anthropic's directory (https://claude.ai/directory/connectors/icp): remove invisible characters from a file the server serves to models, bring the README's dependency snippet up to the released version, and close out the submission record.

Related issues

None.

Changes

• crates/imcp2-core/static/candid-reference.md: strip the byte-order mark at the top of the file and three zero-width spaces (U+200B) that sat after ellipses on lines 153 and 307. The file is include_str!'d into the server and served as candid://reference, and the directory's policy scan looks for invisible characters in model-facing text. No visible content changes.
• README.md: the library snippet now reads imcp2 = "0.6" instead of "0.4"; 0.6.0 is what is on crates.io.
• docs/anthropic-directory-submission.md: the submission log records the 2026-10-27 review (the sign-in rounds and the zero-width-space cause, the Critical Priority finding on the financial guard, the optional suggestion), the 2026-10-28 resolution in 0.6.0 (Ask the user for an unknown app's URL instead of sending the model to a web search #212, Refuse every update to a canister that provides ICRC-1/ICRC-2 methods #213, Refuse update calls whose method name carries a financial keyword #214, Describe the guard's three checks in the server instructions, and drop the keyword scope's exemption list #215, Bump the crates to 0.6.0 #217) with what was verified on production, and the approval and publication, including what the public catalog shows for the listing (the Verified checkmark, all 10 tools, no icon and no categories yet). Blocker 3 records what the test-credentials field actually carried and the lesson for the next edit; the self-serve test-instructions draft is marked superseded; the two 0.5.1 mentions say 0.6.0; the submission-day checklist is closed out with one new open item for the icon and categories; the escalation note says which address reached a person. The listing URL uses the documented permanent form, claude.ai/directory/connectors/SLUG.

Not touched: docs/openai-directory-submission.md. That submission's state is not known to me, so its status is left as is.

Testing

• cargo build --locked --all-targets
• cargo test --locked --all-targets (run with --workspace: imcp2 71 + 8 + 10, imcp2-core 203, imcp2-local 21, all passing)
• cargo fmt --all / cargo clippy --all-targets (fmt clean; clippy reports six warnings in imcp2-core that predate this PR, all in Rust files it does not touch; this PR changes no Rust code)
• npm test --prefix monitoring/mcp-status (dashboard unchanged)

Also verified: a scan of every tracked file for U+200B, U+200C, U+200D, U+2060 and U+FEFF finds none after the change.

Checklist

• I have read the Contributing guidelines.
• Docs (README / comments) updated for any user-visible change.
• No secrets, credentials, or internal-only information are included. The doc names the test account's username, which the reviewer already holds, and not its password.
