A deep upgrade workflow for a library, framework, or programming interface. It checks the official release notes and migration instructions, then adapts the repository to relevant breaking changes.

Use it to compare current and target versions, research official changes, plan a repository-specific migration, update code and configuration, and run checks afterward.

Raising a version number alone can leave code incompatible with the new release. The workflow identifies affected files, orders the changes, and verifies the result with type checks and tests.

deep-update — Skill for Claude Code by GlamgarOnDiscord

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.

Any agent

npx skills add GlamgarOnDiscord/claude-saas-blueprint --skill deep-update

Clone the repo

git clone --depth 1 https://github.com/GlamgarOnDiscord/claude-saas-blueprint

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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.00543
Opus 5	$0.00017	$0.00271
Sonnet 5	$0.00007	$0.00109
Haiku 4.5	$0.00003	$0.00054

Measured 11d ago against content hash 9567b3bc3a42, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

deep-update 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 11d 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.

What it actually says

Deep update — mise à jour profonde

Idée

Tu veux savoir ce qui a changé depuis ta version actuelle et adapter le code proprement, pas seulement monter un numéro de version.

Document maître

Suivre docs/processus-mise-a-jour-profonde.md étape par étape.

Déroulé agent (obligatoire)

A. Cadrage

Identifier une cible principale (X) et la version actuelle dans le repo (fichiers de config, lockfile, imports).
Si plusieurs sujets → proposer de découper en plusieurs sessions.

B. Baseline

Noter versions, chemins des fichiers sensibles, tests existants sur la zone.

C. Recherche profonde

WebSearch + WebFetch sur les pages officielles : release notes, migration guide, dépréciations.
Synthèse structurée :
- Breaking changes pertinents pour ce repo (pas tout le changelog).
- Fichiers à modifier (liste).
- Ordre des opérations (types → runtime → config).

D. Plan court

3–10 puces : QUOI changer, POURQUOI (réf. doc), COMMENT (fichiers).

E. Exécution clean

Modifications minimales mais complètes (pas de TODO laissés sans issue).
Pas de contournement type any massif sans plan de retypage.

F. Examine

tsc, tests ciblés, lint. Fail-stop : 2 échecs sur le même point → réanalyser la doc.

G. Mémoire

Mettre à jour .claude/memory/stack.md (versions). Décision notable → decisions.md ou ADR.

Différence avec `/deps`

/deps = inventaire, vulnérabilités, outdated en masse.
/deep-update = un sujet, veille changelog approfondie, migration raisonnée.

Liens

/apex pour structurer la session si le chantier est large.
/scope-task si tu hésites sur les fichiers à ouvrir en premier.

Changes

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.
