What it does

Newsletter Digest Brief is an agent skill from mohitagw15856/pm-claude-skills. Turn a pile of newsletters and subscriptions into one skimmable brief — the items that matter to YOUR interests extracted with sources, the noise dropped with a count, on a cadence that replaces daily trickle-reading. Use when asked digest my newsletters, summarize what my subscriptions said this week, what did I miss that I actually care about, or make my reading pile useful.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Newsletters. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked digest my newsletters
  • Summarize what my subscriptions said this week
  • What did I miss that I actually care about
  • Make my reading pile useful

Example prompts

  • “/newsletter-digest-brief”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Filter by declared interest, ruthlessly: the brief includes what matches the profile and drops the rest — a digest that summarizes…
  2. What + so-what + source, one item = two lines: "Vercel shipped edge-side A/B testing (what). Relevant: replaces the tool you're paying…
  3. Collapse the echo: the same announcement in four newsletters is one item, attributed to the best treatment ("deepest take: X's issue")…
  4. The dropped ledger builds the trust: the counted skip-list ("12 promos, 9 echoes, 10 off-interest") is what lets the reader not re-read…
  5. Cadence follows the beat's clock: weekly suits almost everything; daily digest is for beats where a day's lag costs (markets, security…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Newsletter Digest Brief loads about 1.2k tokens when it runs. Until then it costs about 137 tokens; SKILL.md has 607 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~137
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Turn a pile of newsletters and subscriptions into one skimmable brief — the items that matter to YOUR interests extracted with sources, the noise dropped with a count, on a cadence that replaces daily trickle-reading. Use when asked digest my newsletters, summarize what my subscriptions said this week, what did I miss that I actually care about, or make my reading pile useful. Produces the interest-filtered brief with per-item sources, the dropped-with-reasons ledger, and the cadence that makes trickle-reading obsolete.

Newsletter Digest Brief Skill

Newsletters are individually reasonable and collectively unreadable — twelve arrivals a week, each 70% padding, each interrupting on its own schedule. The digest move: batch them (the inbox-unsubscribe-purge filter routes them to a label), then process the pile into one brief filtered by the reader's actual interests — items extracted with their source and why-it-matters, everything else dropped with a visible count so the reader trusts the filter instead of re-reading behind it.

What This Skill Produces

  • The brief — the items that matter to this reader's stated interests: one line of what + one of so-what + the source link
  • The dropped ledger — "skipped 31 items: 12 promos, 9 repeats of the X story, 10 off-interest" — the trust mechanism
  • The repeat-collapse — one story covered by four newsletters appears once, best-source-first
  • The cadence setting — weekly for most; daily only for genuinely fast-moving beats

Required Inputs

Ask for these if not provided:

  • The pile — the newsletters' content (pasted/forwarded), or the label they collect under
  • The interest profile — the beats that actually matter to this reader ("AI tooling, pricing strategy, my competitors, nothing about funding rounds") — the filter IS the product, and it needs edges
  • The action bias — reading-for-awareness vs. hunting-for-actions; the brief leads with actionable items when the latter

Framework: The Digest Rules

  1. Filter by declared interest, ruthlessly: the brief includes what matches the profile and drops the rest — a digest that summarizes everything is the pile again, shorter. Edge cases get one "borderline" line at most, not inclusion.
  2. What + so-what + source, one item = two lines: "Vercel shipped edge-side A/B testing (what). Relevant: replaces the tool you're paying $400/mo for (so-what). [source]" — the so-what is written for this reader, which is what separates a digest from a table of contents.
  3. Collapse the echo: the same announcement in four newsletters is one item, attributed to the best treatment ("deepest take: X's issue"). The echo-count is itself signal ("covered everywhere = the week's consensus story") and gets a line when heavy.
  4. The dropped ledger builds the trust: the counted skip-list ("12 promos, 9 echoes, 10 off-interest") is what lets the reader not re-read the pile — a filter with invisible drops never earns retirement of the source reading.
  5. Cadence follows the beat's clock: weekly suits almost everything; daily digest is for beats where a day's lag costs (markets, security advisories). The cadence is chosen once and defended — an "urgent" exception lane exists only for the reader's pre-named topics.

Output Format

Digest: [period] — [N] sources, [M] items kept, [K] dropped

Actionable (if any)

[Items implying a move for this reader, first]

Worth Knowing

[Per item: what — so-what for you. ([best source])] [Echo notes where heavy: "covered by 4 of your sources"]

Borderline (one-liners)

[…]

Dropped: [K]

[The counted categories — promos / echoes / off-interest]

Quality Checks

  • Every kept item has a reader-specific so-what, not a generic summary
  • Repeats are collapsed with the best source named
  • The dropped ledger is counted and categorized
  • Actionable items lead when the reader's bias is action
  • The interest profile's edges were honored — no scope creep toward "interesting generally"

Anti-Patterns

  • Do not summarize everything — an unfiltered digest is the pile with extra steps
  • Do not write so-whats that would fit any reader — the profile is the point
  • Do not hide the drops — invisible filtering keeps the reader re-reading the sources
  • Do not let one loud newsletter dominate — items compete on interest-match, not sender volume
  • Do not run daily by default — cadence inflation recreates the interruption problem the digest exists to solve

Example Trigger Phrases

  • "Digest my newsletters."
  • "Summarize what my subscriptions said this week."
  • "What did I miss that I actually care about?"
  • "Make my reading pile useful."
