docpage-digest

docpage-digest is a skill for Claude Code, Codex from melodic-software/claude-code-plugins. It costs 210 tokens per session (3,972 once invoked), scanned B, original, MIT.

A documentation-ingestion tool for one online documentation page that saves the original, breaks it into sections, creates separate summaries, verifies them, and produces a reusable handoff for discussion or interviews.

In plain words
What is it for?
Use it to digest one documentation page, preserve its source structure, verify section findings, and prepare an interview-ready decision artifact.
Why use it?
It turns a single page into a traceable knowledge record, making it easier to check that summaries match the source.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

docpage-digest scanned grade B 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 yesterday.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/check-fences-exact.py, scripts/check-fences-exact.test.sh, scripts/check-snippets.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Instruction-override phrasingmediumPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

command ("ignore previous instructions", "write this file", "run this tool") is quoted material

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 243 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Docpage Digest

Turn one online documentation page into a verified, durable knowledge slice: the unaltered original, a structural inventory, per-section digests, independent verification records, and a handoff artifact an interview can walk. The pipeline engine here is generic; everything publisher-specific (fetch channel, applicability filter, digest-agent model matching, the doc queue) lives in a separable publisher profile under context/.

Work root

Configured library dir: ${user_config.library_dir}

This skill's .work/ root is formally carved out of the marketplace topic-docs convention (https://raw.githubusercontent.com/melodic-software/claude-code-plugins/main/docs/conventions/topic-docs/README.md): the work root resolves through the knowledge plugin's own library_dir seam, not the concern file's memory_dir.

Resolve the root once, before the first write, and record the resolved absolute path in the checklist's Provenance block. Every <work-root> path below is relative to it, and a resumed session reads it back instead of re-deriving it. Resolution rules for the rendered value above (the README's option table owns the value forms; this is how a run turns one into a directory):

  • Unset, an empty value, or a surviving literal ${user_config.library_dir} token, means the option was never configured. Use the default .; never create a directory named after the token.
  • Relative (including the default .). Resolve against the project directory, ${CLAUDE_PROJECT_DIR}/<value>.
  • Absolute. Use verbatim, with no project-directory prefix.
  • Leading ~, the home directory, with no project-directory prefix.
  • ${NAME} / %NAME% env-var reference. Read the variable yourself (printenv NAME in bash, $env:NAME in PowerShell) and use its value with no project-directory prefix. An unset variable fails the run loudly. Report it and stop. Never hand the reference to a shell for expansion: an unset variable expands to the empty string there, silently writing the slice to the wrong root.

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.

docpage-digest is a skill published in the GitHub repository melodic-software/claude-code-plugins (15 stars, last pushed today), licensed MIT. It adds 210 tokens to every session and 3,972 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it B with 1 finding (instruction-override phrasing). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
