last30days Skill

Agent Skills package for researching any topic across Reddit, X, YouTube, and web. Installable across Claude Code (most common host), Codex, Cursor, GitHub Copilot, Gemini CLI, and 50+ other Agent Skills hosts. Python scripts with multi-source search aggregation.

Structure

• skills/last30days/SKILL.md — canonical skill definition / runtime spec the model reads when the slash command fires
• skills/last30days/scripts/last30days.py — main research engine
• skills/last30days/scripts/lib/ — search, enrichment, rendering modules
• skills/last30days/scripts/lib/vendor/bird-search/ — vendored X search client
• docs/solutions/ — documented solutions to past problems (bugs, best practices, workflow patterns), organized by category with YAML frontmatter (module, tags, problem_type)
• CONCEPTS.md — shared domain vocabulary (Skill, Engine, Harness, Beta channel) — relevant when orienting to the codebase or discussing project terminology
• CONFIGURATION.md — user-facing knobs (env vars, flags, per-host install patterns); keep in sync per the rules below
• CHANGELOG.md — structured release history (launch copy lives in GitHub Releases)
• HERMES_SETUP.md — install instructions for the Hermes harness specifically

Orientation

• This is an Agent Skills package, not a CLI tool. The product is the slash-command-invoked skill (/last30days <topic> in most harnesses); scripts/last30days.py is implementation. Claude Code is the most common host but not the only one — features must work across every harness the skill installs into.
• Feature design starts from the slash-command UX. A new engine flag with no SKILL.md integration is incomplete — the model invoking the skill won't know the flag exists.
• README and PR examples show /last30days <topic> first. Direct CLI invocation (python3 scripts/last30days.py ...) is a fallback for scripting, cron, and dev-time engine testing; label it as such, never as the primary path.
• Slash commands don't pass shell mechanics through. /last30days OpenClaw --emit=html | pbcopy is invalid in any harness — either use the slash form (no flags or pipes; let the model translate user intent into engine flags) or use the direct CLI form (full python3 ... with explicit flags and a real shell).

Commands

# Dev/fallback: direct engine invocation (scripting, cron, or engine testing only).
# Saves to $LAST30DAYS_MEMORY_DIR when set in shell or ~/.config/last30days/.env;
# add --save-dir <path> for a one-off override. Mirrors LAST30DAYS_STORE convention.
python3 skills/last30days/scripts/last30days.py "test query" --emit=compact
npx skills add . -g -y   # copies skill into ~/.agents/skills/<name>/ (frozen at install time); re-run to sync working-tree edits — see Rules below

# Tests (pytest, ~89 files under tests/, configured in pyproject.toml)
uv run pytest                              # full suite
uv run pytest tests/test_dedupe_v3.py      # single file
uv run pytest tests/test_dedupe_v3.py -k some_case   # single case
uv run pytest --cov                        # with coverage (skips lib/vendor/)

Python 3.12+ required. Use uv for the env; the venv lives at .venv/.

Rules

• lib/__init__.py must be bare package marker (comment only, NO eager imports)
• One-time setup: npx skills add . -g -y copies the skill into ~/.agents/skills/<name>/ (real directory) and, for harnesses that support symlinked skill dirs, drops a per-host symlink pointing at that copy. Working-tree edits do NOT propagate automatically — the ~/.agents/skills/<name>/ copy is frozen at install time. To sync after edits, re-run npx skills add . -g -y. For live-edit on a dev machine, replace the install copy with a symlink to the working tree: ln -sfn "$PWD/skills/last30days" ~/.agents/skills/last30days (run from the repo root).
• Git remote: origin = public (mvanhorn/last30days-skill)
• Every lib/*.py call to log.source_log(...) must pass tty_only=False. The default is True, which silently drops every line when stderr isn't a TTY (Claude Code, Codex, CI, captured output) — turning source observability into invisible failure. Enforced by tests/test_source_log_visibility.py.
• CLI-gated optional sources (Digg via digg-pp-cli, YouTube via yt-dlp) activate only when shutil.which resolves the binary on the agent subprocess PATH — not merely when the file exists on disk. First-run setup installs Digg through @mvanhorn/printing-press-library (default $HOME/.local/bin); Hermes/OpenClaw gateways often need that directory on PATH. Setup must distinguish PATH-visible installs from off-PATH binaries and must not claim "now active" unless the engine gate would pass. See docs/solutions/integration-issues/digg-cli-agent-path-setup-wizard.md.

Security hygiene

• Never commit real API keys, browser cookies, auth tokens, app passwords, access tokens, or .env contents.
• Use the env-based auth patterns in skills/last30days/scripts/lib/env.py; tests and fixtures must use obvious dummy values only.
• Keep examples safe by redacting secrets and avoiding copy/pasteable live credentials in docs, fixtures, and test data.
• Do not weaken or disable the advisory security workflow (.github/workflows/security.yml) without explaining why in the PR description or review thread.

Maintaining CONFIGURATION.md

CONFIGURATION.md is the user-facing configuration reference — save paths, per-source API keys, web-search backend priority, trend-monitoring stack, per-client install patterns. Distinct from SKILL.md (the canonical runtime spec).

Update CONFIGURATION.md when:

• adding a new env var (e.g. LAST30DAYS_*, BSKY_*, *_API_KEY)
• adding a new CLI flag that affects configuration (e.g. --store, --web-backend)
• adding a new per-client install pattern (Claude Code, Gemini, Codex, Cursor, Hermes…)
• adding a new optional source that requires its own credential
• changing the priority order of config layers (per-run flag > env > .env file > defaults)

Keep the existing structure organized by how often each layer is touched: per-run flags → env vars / .env → optional trend-monitoring stack → per-client patterns. Add new content into the right section rather than appending at the end.

When a new config concept lands in SKILL.md or AGENTS.md, mirror the user-facing knob in CONFIGURATION.md so non-agent readers can configure the skill without reverse-engineering it from the runtime spec.

Beta channel

Experimental changes get tested on mvanhorn/last30days-skill-private, which installs as a parallel /last30days-beta slash command. Beta-only changes never ship to public without a review PR here. Workflow guide lives at BETA.md in the private repo. Plan that established this setup: docs/plans/2026-04-17-005-feat-beta-skill-from-private-repo-plan.md.
