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 | $0.00124 | $0.01966 |
| Opus 5 | $0.00062 | $0.00983 |
| Sonnet 5 | $0.00025 | $0.00393 |
| Haiku 4.5 | $0.00012 | $0.00197 |
Grade A, and why
fpf-work-guide 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FPF Work Guide (Claude-native)
This is the Claude Code build of the FPF Work Guide. It shares its refresh,
cache, and protocol logic with the Codex build: the scripts/ and references/
in this skill directory are copied unchanged from the canonical source in
skills/fpf-work-guide/. Only the routing contract, paths, and packaging here
are Claude-native.
Document Roles
This SKILL.md is the routing contract Claude reads when the skill triggers.
Keep it focused on when to refresh FPF context, how to use protocol and chunk
sources, and what must be disclosed in substantive work.
Canonical detail sources (read on demand, do not inline):
references/diagnostics.md— refresh gate, environment, chunk, and protocol diagnostic fields.references/chunk-lookup.md— FPF chunk layout and pattern lookup.references/protocol-trust.md— protocol repository trust boundary and instruction-source policy.references/source-selection.md— source selection for FPF-backed answers.references/release-notes.md— user-visible release changes and publication boundaries.
How The Gate Runs In Claude Code
There are three native entry points; you do not need all of them:
- SessionStart hook (recommended) — if installed, the gate runs once at session start and its output is added to context. When that output is already present, do not run the gate again unless a forced refresh is needed.
/fpf-contextslash command — runs the gate on demand and asks you to use its output before substantive FPF-backed work.- This skill — when the skill triggers and no fresh gate output is in context, run the gate yourself as the first step (below).
Required First Move
Before any substantive answer, code edit, review, plan, or delegated task — and only if fresh gate output is not already in context — run the FPF context refresh gate:
FPF_WORK_GUIDE_SKILL_DIR="${FPF_WORK_GUIDE_SKILL_DIR:-$HOME/.claude/skills/fpf-work-guide}" \
FPF_CACHE_HOME="${FPF_CACHE_HOME:-$HOME/.cache/fpf-work-guide}" \
FPF_UPDATE_STATE_DIR="${FPF_UPDATE_STATE_DIR:-$HOME/.local/state/fpf-work-guide}" \
bash "$FPF_WORK_GUIDE_SKILL_DIR/scripts/update_fpf_context.sh"
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

fpf-work-guide is a skill published in the GitHub repository ansea09/agent-skills-and-protocols (2 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 1,966 once invoked, about $0.0006 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 2026-08-31.
