Conciseness

The body is mostly lean — command tables, copy-paste examples, and terse key rules — with only minor trimmable content: the host-specific `!` shell-probe wrapper paragraph (mentioning Codex), the "Current environment status" probe blocks, and repeated read-only statements. Not score 3 because nothing explains concepts Claude already knows; not score 5 because the probe/Codex material is off-topic noise that does not earn its tokens.

Actionability

Fully executable, copy-paste-ready commands cover the common cases: `tdl chat ls -o json`, `-f "VisibleName contains 'Bloomberg'"`, `tdl chat export -c @channel_name -T last -i 20 --all --with-content -o /tmp/tdl-export.json`, plus a concrete error/fix diagnostics table. This matches the 5 anchor.

Workflow Clarity

A clear 6-step sequence (install → auth → identify → execute → present → diagnose) with explicit validation checkpoints — install probe, `tdl chat ls --limit 1` auth check before other commands, start-small rule — and feedback loops for error recovery (FLOOD_WAIT wait-and-retry, re-auth on session errors). Read-only skill, so the destructive/batch cap does not apply.

Progressive Disclosure

Good structure: the body is a readable overview and the one-level-deep reference `references/commands.md` (verified to exist and well-organized) is clearly signaled with its purpose and when to read it. Minor gap: chat-identifier formats and login-method detail partially duplicate the reference and could live there, keeping it below 5.

Specificity

Lists several concrete actions — "list chats and channels, find a channel by name, and export recent messages or a date or ID range" — with only minor gaps (topic/thread export is not mentioned). It is above score 3 because it covers more than 1-2 actions, but below score 5 because coverage is not fully comprehensive.

Completeness

Clearly answers both questions: the first sentence states what the skill does, and "Use this skill whenever the user wants to check their Telegram, see what's new in their channels..." provides explicit, concrete trigger phrases. This matches the 5 anchor exactly.

Trigger Term Quality

Good natural keyword coverage: "check their Telegram", "see what's new in their channels", "read or export messages from a news, crypto, or trading channel or group", "market news and signals". A few natural variations (e.g., "catch up on my Telegram", "monitor a channel") are missing, keeping it below 5.

Distinctiveness Conflict Risk

Clear niche — reading Telegram channels/groups via the tdl CLI for financial news — with distinct triggers and an explicit read-only boundary ("it cannot send messages or join or leave channels"), so conflict risk with other skills is minimal.
