Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00098 | $0.04397 |
| Opus 5 | $0.00049 | $0.02198 |
| Sonnet 5 | $0.00020 | $0.00879 |
| Haiku 4.5 | $0.00010 | $0.00440 |
Grade A, and why
journal-review scanned grade A with 0 findings 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 5d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/journal-review Workflow
Inputs
User provides:
- Review period: "this week", "last week", "last N days", "this sprint", a date range (YYYY-MM-DD to YYYY-MM-DD), or omitted (defaults to "this week")
- Optional: category filter (decisions, learnings, actions, themes, or all)
Scope parameters:
JOURNAL_BASE:~/journal/(hardcoded, matches /journal and /journal-recall skills)REVIEW_CATEGORIES: decisions, learnings, actions, themesDECISION_SIGNALS: "decided", "chose", "went with", "opted for", "tradeoff", "picked", "selected", "decision:"LEARNING_SIGNALS: "learned", "discovered", "figured out", "TIL", "gotcha", "insight", "realization", "aha"ACTION_SIGNALS: "- [ ]", "TODO", "follow up", "need to", "action item", "next step"- Default review period: "this week" (Monday of current week through today)
Step 0 — Configure Review Period
Action: Parse user input to determine the date range for the review.
Date resolution rules:
- "this week" (or omitted): Monday of current week through today (inclusive)
- "last week": Monday through Sunday of previous week
- "last N days": Today minus N through today (inclusive)
- "this sprint": Last 14 days (2-week sprint default)
- Date range (YYYY-MM-DD to YYYY-MM-DD): Exact range specified
- Single date: That date only
Validation:
- Start date must not be in the future
- End date must be >= start date
- Range must not exceed 90 days (safety limit)
- If validation fails, report error and FAIL
Category filter:
- If user specifies a category, only scan for that category
- Default: all categories (decisions, learnings, actions, themes)
Tool declarations: Bash (date calculations)
Checkpoint: Review period resolved to concrete start/end dates, categories determined
Step 1 — Scan Daily and Meeting Entries
Action: Read all daily and meeting entries within the review period.
File discovery:
- Use Glob to find daily entries:
$JOURNAL_BASE/daily/*.md - Filter by date range: parse
YYYY-MM-DDfrom filename, include if within [start, end] - Use Glob to find meeting entries:
$JOURNAL_BASE/meetings/*.md - Filter meetings by date: parse
YYYY-MM-DDprefix from filename - Read all matching files
What this file has done since we first saw it
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.

journal-review is a skill published in the GitHub repository backspace-shmackspace/claude-devkit (15 stars, last pushed 12d ago), licensed MIT. It adds 98 tokens to every session and 4,397 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
capture-to-vault
Use during /research, /scope (or any recipe) to write or update a vault note via dossier-mcp. Agent drafts slug + frontmatter + body + citations, writes the note, and surfaces what was captured so the user can redirect afterward. Supports create (new note) and update (refine existing note) modes.
load-context
Use at the start of /research and other workflow recipes to establish vault grounding. Loads vault bootstrap (profile.md), checks inbox, and pre-warms project context if a topic anchor is implied. Repo/git detection lands with /plan and /implement.
golang-security
Security best practices and vulnerability prevention for Golang. Covers injection (SQL, command, XSS), cryptography, filesystem safety, network security, cookies, secrets management, memory safety, and logging. Apply when writing, reviewing, or auditing Go code for security, or when working on any risky code involving…
company-brain
Your team's shared, AI-ready knowledge base — people, companies, meetings, SOPs, and decisions structured so Claude can answer questions on your team's behalf. Team-scope sibling to second-brain (which is personal-scope). Seven modes — capture (drop something into the right structured dir), compile (process into wiki…

Searchable Elixir/Phoenix/Ecto solution documentation system with YAML frontmatter. Builds institutional knowledge from solved problems. Use when consulting past solutions before investigating new issues.
