docs: replace restated upstream facts with pointers in knowledge and computer-use #12775

Refs #12694

Outcome

14 passages in 9 files state a fact an external source owns. Rewrite each as a pointer to the live upstream section, or remove it, so the next upstream change cannot leave a stale copy here. Plugins: knowledge, computer-use.

Done when

• Every row below is fixed: the restated value is deleted, the local decision stays in this repository's own words, and the pointer goes to the exact upstream section with an as-of date and a recheck trigger, per .claude/rules/skill-bodies-state-current-rules.md. A record beside a restated value does not fix it. A row marked Remove has no local dependency on the fact.
• The PR passes check-stamps.sh --trigger-less (plugins/attribution/skills/audit/scripts/check-stamps.sh) on the files it touches.
• Each touched plugin has a changelog fragment.

Scope: the knowledge and computer-use rows of #12694 only: docs/contracts/plugin-reconfiguration/README.md, plugins/knowledge/README.md, plugins/knowledge/skills/distill/SKILL.md, plugins/knowledge/skills/docpage-digest/SKILL.md, plugins/knowledge/skills/docpage-digest/context/anthropic-docs-profile.md, plugins/knowledge/skills/setup/SKILL.md, plugins/computer-use/README.md, plugins/computer-use/skills/diagnose/SKILL.md, plugins/computer-use/skills/setup/SKILL.md. The context-guard and disk-hygiene rows belong to the sibling child.

Rows

knowledge

• docs/contracts/plugin-reconfiguration/README.md:116-118 (r311). Pointer: https://code.claude.com/docs/en/plugins/manifest-reference#reference-a-saved-value Drop the description of when user_config and CLAUDE_PLUGIN_OPTION_* are injected; keep the rule that observation is next-session and a same-session check reports the old value, with a pointer.
• plugins/knowledge/README.md:82-84 (r313). Pointer: https://code.claude.com/docs/en/tools-reference#read-tool-behavior Drop the claim that PDF works natively with Read; keep the requirement of a PDF or EPUB the user may read and the EPUB unzip note, and point at the Read tool section. Same text also at: plugins/knowledge/skills/distill/SKILL.md:42; a row of its own covers it only if listed.
• plugins/knowledge/README.md:121-122 (r309). Pointer: https://code.claude.com/docs/en/plugins/manifest-reference#where-values-are-stored Drop the claim about how a sensitive option persists on Windows; keep the decision that course-platform credentials stay in shell env vars, not userConfig, with a pointer.
• plugins/knowledge/skills/distill/SKILL.md:188,254 (r314). Pointer: https://code.claude.com/docs/en/tools-reference#write-tool-behavior Drop the claims that git mv invalidates or breaks Claude Code's read tracking; keep the instruction to Read the file at its new path before Edit/Write, and point at the Write tool section.
• plugins/knowledge/skills/docpage-digest/SKILL.md:48-51 (r316). Pointer: https://www.gnu.org/software/coreutils/manual/html_node/sha2-utilities.html#67-sha2-utilities-print-or-check-sha-2-digests Drop the claim about which platforms lack sha256sum; keep the hash8 slug rule and the sha256sum-or-shasum command, and point at the sha2 utilities section.
• plugins/knowledge/skills/docpage-digest/SKILL.md:48-51 (r317). Pointer: https://www.gnu.org/software/coreutils/manual/html_node/sha2-utilities.html#67-sha2-utilities-print-or-check-sha-2-digests Drop the clause on stock macOS lacking sha256sum; keep step 3's hash8 rule, the command and truncating the prefix not the hash, with a pointer.
• plugins/knowledge/skills/docpage-digest/context/anthropic-docs-profile.md:38,40-41 (r318). Pointer: none found; No fetched page documents the raw .md channel output (llms.txt only lists pages). Search the Claude Code docs for a page describing the raw markdown form; if none exists, the PR should remove these sentences instead. Drop the list of channel artifacts (fence attributes, tab expansion, escaped URLs); keep that source.* stays the unaltered fetch and the reproduce-never-repair decision, with a pointer to the owner.
• plugins/knowledge/skills/setup/SKILL.md:95-97 (r321). Pointer: https://code.claude.com/docs/en/plugins/manifest-reference#where-each-variable-resolves Drop the explanation of when ${user_config.*} is injected; keep the instruction to rerun check in a fresh session and report the observed value, and point at the section.

computer-use

• plugins/computer-use/README.md:32-34 (r060). Pointer: https://code.claude.com/docs/en/computer-use#screenshots-are-downscaled-automatically Drop the pixel-budget explanation and the claim that smaller monitors do not help; keep the decision that zoom is the lever, and point at the downscaling section. Same text also at: plugins/computer-use/skills/diagnose/SKILL.md:75-77, plugins/computer-use/skills/diagnose/SKILL.md:37-38; a row of its own covers it only if listed.
• plugins/computer-use/skills/diagnose/SKILL.md:75-77 (r061). Pointer: https://code.claude.com/docs/en/computer-use#screenshots-are-downscaled-automatically Drop the megapixel-count explanation; keep the instruction to read the reference file before advising on resolution, and point at the downscaling section. Same text also at: plugins/computer-use/README.md:32-34, plugins/computer-use/skills/diagnose/SKILL.md:37-38; a row of its own covers it only if listed.
• plugins/computer-use/skills/setup/SKILL.md:44-46,117-119 (r062). Pointer: none found; Upstream owner of the computer-use MCP tool descriptions (list_granted_applications, request_access); the fetched computer-use page does not name them. Search the docs for a tool reference or confirm via the /mcp tool listing. Drop what list_granted_applications returns and its read-only/no-side-effect description, in both places; keep the decision to use it as the check's probe, with a pointer.
• plugins/computer-use/skills/setup/SKILL.md:60-61,117-118 (r063). Pointer: https://code.claude.com/docs/en/computer-use#approve-apps-per-session Drop the statement that request_access raises a consent dialog, in both places; keep the rule never to call it during a check, and point at the approval section.
• plugins/computer-use/skills/setup/SKILL.md:65-66 (r064). Pointer: none found; Upstream doc on whether synthesized input resets the OS idle timer (Windows/macOS input injection or idle-detection docs); the computer-use page does not cover it. If none exists, reclassify as local measurement. Drop the claim that synthesized input does not reset the idle timer; keep the decision to probe and report the three timeouts, and point at an owner source once found. Same text also at: plugins/computer-use/README.md:29-31, plugins/computer-use/skills/diagnose/SKILL.md:42, plugins/computer-use/skills/setup/SKILL.md:79-81; a row of its own covers it only if listed.
• plugins/computer-use/skills/setup/SKILL.md:104-107 (r065). Pointer: https://code.claude.com/docs/en/computer-use#approve-apps-per-session (confirm the section) Drop the description of the allowlist gate's refusal and its error text; keep reporting focus-stealing utilities as INFO with the retry pattern, and point at the approval section. Same text also at: plugins/computer-use/skills/diagnose/SKILL.md:41, plugins/computer-use/skills/diagnose/SKILL.md:80-81; a row of its own covers it only if listed.

Notes

Drafted by the issue-triage session. Agent choice, not an owner answer. Split from #12694 by whole plugins, so no file is touched by both children; every file above exists on origin/main. Size Medium from the passage count (14 of the parent's 28, which intake sized Large). Three rows (r318, r062, r064) have no pointer found yet and need a docs search before writing; the rule for each is in its row.

Lines are as of 3bd42cabfe (https://github.com/melodic-software/claude-code-plugins/blob/3bd42cabfe6bdef37a05778d396869af0381bb51); locate each passage by its text if main has moved. Each rNNN is that row's number in the order of #7292's "Findings by plugin". Pointers are candidates: fetch each before writing it, and confirm the section still documents the fact.
